Abstract
BACKGROUND AND OBJECTIVES Soy products are essential to the daily life of the Chinese population. However, the association between soy products and serum uric acid remains unclear. Better understanding of their relationship could provide food choice information for patients with gout. This study assessed the acute effects of soy and soy products on serum uric acid. METHODS AND STUDY DESIGN Sixty healthy adult male volunteers were recruited and randomly assigned to six groups. Ten participants in each group randomly ingested one of six foods: water, soy, and four different soy products. A blood test was conducted after 3 h to examine uric acid concentration. RESULTS The serum uric acid concentration significantly increased by 21.4±23.4 μmol/L at 1 h and 16.3±19.4 μmol/L at 2 h following ingestion of whole soybeans. These changes also applied to the soy powder group. The serum uric acid concentration rapidly increased by 38.1±20.5 μmol/L at 1 h, 34.4±18.2 μmol/L at 2 h, and 24.1±24.2 μmol/L at 3 h after the ingestion of soybean milk. The maximum concentration of serum uric acid was observed at 1 h after intake of soybeans and soy products, and then gradually decreased during the subsequent 2-h period. No significant uric acid changes from ingesting bean curd cake and dried bean curd stick were detected. CONCLUSIONS Ingesting different soy products resulted in different concentrations of serum uric acid, with soybeans, soybean milk, and soy powder considerably increasing serum uric acid.

Abstract
STUDY QUESTION Is soy formula feeding during infancy associated with menstrual pain in reproductive-age women? SUMMARY ANSWER Our data suggest that soy formula feeding during infancy is associated with several indicators of severe menstrual pain in reproductive-age women. WHAT IS KNOWN ALREADY A prior study observed greater severity of menstrual pain in young women who as infants participated in feeding studies and were assigned to soy-based formula feeding. STUDY DESIGN, SIZE, DURATION We used data from the Study of Environment, Lifestyle & Fibroids (SELF), a cohort of 1696 African-American women ages 23-35 years at enrollment. PARTICIPANTS/MATERIALS, SETTINGS, METHODS Data on infant soy formula feeding was ascertained by self-administered questionnaire for 1553 participants, with 89% of participants receiving assistance from their mothers. Information on menstrual pain indicators was collected by web- and telephone-interview. We estimated the relative risk (RR) and 95% confidence interval (CI) using log-binomial regression, or log-multinomial regression, adjusting for participant age and maternal education. MAIN RESULTS AND THE ROLE OF CHANCE Women ever fed soy formula as infants were more likely than unexposed women to report ever use of hormonal contraception for menstrual pain (RR 1.4, CI: 1.1-1.9) and moderate/severe menstrual discomfort/pain with 'most periods', but not 'every period', during early adulthood (ages 18-22 when not using hormonal contraception) (RR 1.5, CI: 1.1-2.0). LIMITATIONS, REASONS FOR CAUTION We relied on retrospective recall to ascertain infant exposure to soy formula feeding and data on menstrual pain indicators. WIDER IMPLICATIONS OF THE FINDINGS Our observations add to the growing body of literature from animal and human studies on the reproductive health consequences of early-life exposure to soy formula. STUDY FUNDING/COMPETING INTEREST(S) This research was supported by the Intramural Research Program of the NIH, National Institute of Environmental Health Sciences and, in part, by funds allocated for health research by the American Recovery and Reinvestment Act. This research was also supported by grant K99NR017191 (KU). None of the authors has a conflict of interest. TRIAL REGISTRATION NUMBER Not applicable.

Abstract
Estrogens play a key role in an extensive range of physiological functions in various types of tissues throughout the body in females. We previously showed that estrogen insufficiency caused muscle weakness that could be rescued by estrogen administration in a young female ovariectomized (OVX) mouse model. However, long-term estrogen replacement therapy increases risks of breast cancer and cardiovascular diseases. Soymilk contains plant-based protein and isoflavones that exert estrogen-like activity. Here we examined the effects of prolonged soymilk intake on muscle and its resident stem cells, called satellite cells, in the estrogen-insufficient model. Six-week-old C57BL/6 OVX female mice were fed with a dried soymilk-containing diet. We found that prolonged soymilk intake upregulated grip strength in OVX mice. Correspondingly, cross-sectional area of tibialis anterior muscle was significantly increased in OVX mice fed with soymilk. Furthermore, soymilk diet mitigated dysfunction of satellite cells isolated from OVX mice. Thus, these results indicated that prolonged soymilk intake is beneficial for improving muscle weakness in an estrogen-insufficient state in females.

Abstract
INTRODUCTION Even with the ultimate medical management, more than one-third of diabetic patients develop diabetic nephropathy. To our knowledge, there is no study that has examined the effect of probiotic soy milk on kidney function in type 2 diabetic patients with nephropathy. This clinical trial aimed to assess the effects of consumption of probiotic soy milk, compared with conventional soy milk, on kidney-related indexes in patients with diabetic nephropathy. MATERIALS AND METHODS In a randomized double-blinded placebo-controlled trial, 44 patients were randomly assigned to receive 200 mL/d of either soy milk containing Lactobacillus plantarum A7 or conventional soy milk for 8 weeks. Primary endpoints included urinary albumin excretion, estimated glomerular filtration rate, interlukin-18, serum sialic acid, and serum creatinine. Fasting blood samples and morning fasting spot urine samples were collected at the beginning and after 8 weeks for evaluation of biochemical parameters. RESULTS Forty patients completed the study. Administration of probiotic soymilk resulted in a significant reduction in albuminuria (P = .03), serum creatinine (P < .001), serum interleukin-18 (P = .002), and serum sialic acid (P = .001) compared with conventional soy milk. Probiotic soymilk supplementation also led to a significant improvement in estimated glomerular filtration rate (15.9 ± 10.8 mL/min versus 3.2 ± 8.4 mL/min, P < .001) compared with the control group. CONCLUSIONS Probiotic soy milk was safe and well-tolerated by patients with diabetic nephropathy for 8 weeks. Probiotic soy milk also improved indexes of kidney function in type 2 diabetic patients with nephropathy.

Abstract
Community-based Management of Acute Malnutrition using ready-to-use therapeutic food (RUTF) has revolutionised the treatment of severe acute malnutrition (SAM). However, 25% milk content in standard peanut-based RUTF (P-RUTF) makes it too expensive. The effectiveness of milk-free RUTF has not been reported hitherto. This non-blinded, parallel group, cluster randomised, controlled, equivalence trial that compares the effectiveness of a milk-free soy-maize-sorghum-based RUTF (SMS-RUTF) with P-RUTF in treatment of children with SAM, closes the gap. A statistician randomly assigned health centres (HC) either to the SMS-RUTF (n = 12; 824 enrolled) or P-RUTF (n = 12; 1103 enrolled) arms. All SAM children admitted at the participating HCs were enrolled. All the outcomes were measured at individual level. Recovery rate was the primary outcome. The recovery rates for SMS-RUTF and P-RUTF were 53.3% and 60.8% for the intention-to-treat (ITT) analysis and 77.9% and 81.8% for per protocol (PP) analyses, respectively. The corresponding adjusted risk difference (ARD) and 95% confidence interval, were -7.6% (-14.9, 0.6%) and -3.5% (-9,6., 2.7%) for ITT (P = 0.034) and PP analyses (P = 0.257), respectively. An unanticipated interaction (interaction P < 0.001 for ITT analyses and 0.0683 for PP analyses) between the study arm and age group was observed. The ARDs were -10.0 (-17.7 to -2.3)% for ITT (P = 0.013) and -4.7 (-10.0 to 0.7) for PP (P = 0.083) analyses for the <24 months age group and 2.1 (-10.3,14.6)% for ITT (P = 0.726) and -0.6 (-16.1, 14.5) for PP (P = 0.939) for the ≥24 months age group. In conclusion, the study did not confirm our hypothesis of equivalence between SMS-RUTF and P-RUTF in SAM management.

Abstract
PURPOSE Milk protein ingestion reduces post-meal glycemia when consumed either before or together with carbohydrate foods. The aim of this study was to compare the effects of dairy and soy milk consumed either before (preload) or together with (co-ingestion) a carbohydrate (bread), on postprandial blood glucose, insulin and gastric emptying in healthy participants. METHODS Twelve healthy Chinese male participants were studied on five separate occasions using a randomized crossover design. White wheat bread consumed with water was used as a reference meal. Capillary and venous bloods were sampled pretest and 3.5 h post-test meal for glucose and insulin measurement. Gastric emptying was measured using real-time ultrasonography. RESULTS Co-ingestion of dairy milk or soy milk with bread lowered postprandial blood glucose response and glycemic index. Co-ingesting soy milk with bread increased insulin response and insulinemic index significantly compared to co-ingestion of dairy milk and preload treatments. Preloads (30 min prior to bread) significantly lowered postprandial glycemia and insulinemia compared to co-ingestion. Gastric emptying was slower after co-ingesting dairy milk with bread than after reference meal. CONCLUSIONS Preloading either soy milk or dairy milk results in greater reduction in glycemic response compared to co-ingestion alone. This dietary practice may have therapeutic advantage in communities consuming high GI diets. Optimal glucose control may have the potential for increasing the time of transition from prediabetes to type 2 diabetes in Asian communities.

Abstract
BACKGROUND/PURPOSE The rapid progress of biotechnology and molecular biology has led to genetically modified (GM) crops becoming a part of agricultural production. There are concerns that the issues of the functional ingredients in GM products have not been addressed, such as the bioactivities of soy proteins and isoflavones. This study aimed to investigate the effects of probiotic-fermented GM soy milk on hypercholesterolemia, and atherosclerotic risks in hamsters. METHODS One hundred and twelve male Golden Syrian hamsters (Mesocricetus auratus) were randomly assigned into 14 groups of 8 animals each. Normal- and high-cholesterol experimental diets were supplemented with GM or non-GM soy milk with or without probiotic-fermentation for 8 weeks. Serum and fecal lipid levels were measured. Moreover, aortic plaque in artery were stained, and thiobarbituric acid reactive substance content, super oxide dismutase activity and caralase activity were determined. RESULTS GM or non-GM soy milk with or without probiotic-fermentation significantly decreased (p < 0.05) serum TC levels, compared with a high-cholesterol diet group. TC levels in hamsters fed GM soy milk were not significantly different from TC levels in the non-GM soy milk group (p > 0.05). GM soy milk groups can reduce risk of developing atherosclerosis through lowered oxidative stress and reduced atherosclerotic plaque formation in the aorta, and are thus at least equivalent to non-GM soy milk. CONCLUSION GM soy milk with or without probiotic-fermentation can improve hypercholesterolemia and reduce the risk of atherosclerosis, and is considered substantially equivalent to non-GM soy milk in terms of these bioactive functions.

Abstract
The article is dedicated to the use of a specialized fermented milk product on the basis of soybeans in cardiology practice. 45 patients of both sexes (27 men and 18 women) aged 38 to 69 years (mean age 53.7 +/- 3.1 years) who underwent macrofocal myocardial infarction and abide in the acute period and the period of early rehabilitation have been observed. The data obtained by the comparison of the dynamics of clinical, laboratory and functional parameters in patients, strongly suggests the possibility of increasing the effectiveness of the basic treatment by anti-atherogenic diet with fermented soy drink, enriched with magnesium salts, water-soluble forms of beta-carotene and alpha-tocopherol, ascorbic acid and selenium. 30-35 day inclusion of a fermented soy-based product in comprehensive treatment was accompanied by a marked lipid lowering effect, compared with the standard anti-atherogenic diet. Total cholesterol level in patients from the intervention group (n = 21) decreased by 36.3 per cent, thus reaching the standard level, the corresponding figure in the control group (n = 24) decreased by 24.7 per cent (the difference is statistically significant). Total number of rhythm and conduction disorders in patients receiving product was 1.43 per patient, while it reached 1.83 per patient on the basic therapy and a standard diet. The vast majority were beats, no cases of ventricular fibrillation and one case of atrioventricular block took place in patients from the experimental group. Paroxysmal and atrial fibrillation in the control group of patients were recorded 2 fold more often than in the main group. In addition, three cases of ventricular fibrillation were reported in patients from the control group. Early usage of soy drink 3 fold reduced the incidence of complications in the 10-14 day from the moment of macrofocal myocardial infarction. The frequency of angina attacks per week per patient more significantly reduced under nutritional support, compared with patients receiving standard therapy and diet. The decrease of mean number of nitroglycerin tablets taken per week for one person from the experimental group was equal to 9.0 fold, and in the control group--2.43, this demonstrates a significant strengthening of the effectiveness of basic therapy with early administration of soy product. The recovery of ischemic changes in the electrocardiogram in patients receiving soy product was significantly decreased compared with those receiving standard therapy and anti-atherogenic diet, the degree of reduction in the intervention group was 43.3%, while in the control group--27.5%. These data indicate that the use of soy product in a comprehensive early rehabilitation therapy of patients with macrofocal myocardial infarction significantly reduces the risk of arrhythmias and conduction.

Abstract
Patients with birch pollen allergy may suffer from severe anaphylactic reactions after ingestion of foodstuffs containing soya. The reason for this is similarities in protein structure between a major birch pollen allergen (bet v 1) and Gly m 4, a pollen-related protein in soya. A 65-year-old patient allergic to birch pollen developed an adverse systemic reaction after consumption of a soya-containing drink. The diagnosis could be confirmed by in vitro and skin testing methods. Patients who suffer from birch pollen allergy should strictly avoid the intake of soya-containing foodstuffs.

Abstract
UNLABELLED THE AIM of this study was to evaluate selected parameters of calcium and phosphorus metabolism in children with CMA treated with the following milk substitute formulas: lactose-containing extensively hydrolyzed wheat protein formula, lactose-free extensively hydrolyzed casein protein formula, as well as soy-based formula. MATERIAL AND METHODS The study involved 66 children with CMA aged 2-5 years treated with milk-free diet for at least one year. Group I included 31 children fed with a lactose-containing formula, group II - 35 children treated with lactose-free formula. In all children the mean energy intake and nutritional value of daily food rations were assessed. Serum concentrations of calcium (Ca), phosphorus (P), sodium (Na) and magnesium (Mg) were determined using standard methods. Serum values of 25 hydroxyvitamin D (25-OH D) and parathormone (PTH) were assessed by chemiluminescence, whereas concentrations of biochemical markers of bone formation-bone alkaline phosphatase (BALP), osteocalcin (OC) and bone resorption marker-collagen type I crosslinked C-telopeptide (CTX) were determined by immunoenzymatic methods (ELISA), using specific monoclonal antibodies. RESULTS There were no significant differences in the mean dietary supply of calcium, phosphorus, magnesium, sodium, total protein and vitamin C in children from both groups. In the diets of children from group II, the mean content of lactose (0.5±1.0 vs 10.0±6.8 g/d) and 25-OH vitamin D (4.1±2.3 vs 8.5±4.0 ug/d) were significantly lower and dietary fibre content (14.7±3.9 vs 10.4±3.9 g/d) was higher. Calcium and vitamin D dietary supply was lower with respect to nutritional recommendations in all the studied children, whereas the dietary deficiency of vitamin D was higher in children from group II. The mean serum concentrations of evaluated biochemical parameters did not reveal any differences in children from the study groups and were in the normal ranges. There were also no differences in the mean serum concentration of 25-OH vitamin D, ALP, BALP, CTX and PTH in patients from both groups. The mean concentration of OC was significantly higher in group II (71±26.6 ng/ml) than in children from group I (61.1±23.4 ng/ml) <0.01. Positive correlation was found between OC and CTX in both study groups. CONCLUSIONS 1. In children with CMA basic blood laboratory tests may have limited importance in the evaluation of calcium and phosphorus metabolism. 2. Our results suggest that the disturbances in the balance between bone formation and bone resorption processes may occur in children with CMA treated with lactose-free formulas. 3. In order to assure optimal conditions for achieving adequate bone mass by children with CMA, it is necessary to provide them with regular medical and nutritional care.

Abstract
This study was performed to investigate the beneficial effects of powdered whole soy milk and its hydrolysate, compared to the processed soy milk and its hydrolysate, on the alteration of lipid metabolism and their possible effects on antiobesity in C57BL/6N mice fed a high-fat and -cholesterol diet. The mice were divided into a control group (20% casein) and four test groups for 5 weeks: soy milk (SM, 20% soy milk protein), soy milk hydrolysate (SMH, 20% hydrolyzed soy milk protein), whole soy milk (WSM, 20% whole soy milk protein), and whole soy milk hydrolysate (WSMH, 20% whole soy milk hydrolysate protein). The body weight and adipose tissue weights were significantly lowered in SMH, WSM, and WSMH groups compared to the control group despite providing an isoenergetic diet. Plasma lipid concentrations and hepatic fatty acid synthase (FAS) and glucose-6-phosphate dehydrogenase (G6PD) activities were significantly lowered in all soy milk groups; however, the hepatic lipid contents and malic enzyme (ME) activity were only significantly lowered in the WSM and WSMH groups, compared to the control group. Data suggest that powdered WSM or WSMH appears to be more beneficial than SM or SMH in overall antiobesity and antihyperlipidemic properties following in the order WSMH/WSM, SMH, SM, and casein.

Abstract
BACKGROUND Soy drink replacement in the diet might have beneficial effects on anthropometric and blood pressure values for overweight and obese subjects. Therefore, we are going to determine the effects of soy drink replacements on the weight, waist circumference and blood pressure among overweight and obese female youths. PATIENTS AND METHODS This was a cross-over randomized clinical trial on 23 overweight and obese female subjects. All patients were on a weight reducing diet. There were two trial periods for six weeks (soy drink period and cow's milk period) and a washout period for 3 weeks. In the soy drink period only one glass of soy drink (240 cc) was consumed instead of one glass of cow's milk. RESULTS The mean age of the patients was 22±2 years. Mean of BMI was 28.1±0.5. Weight and waist circumference did not changed significantly after the soy drink period compared to the cow's milk period. Systolic blood pressure reduced significantly following the soy drink period (mean percent change in soy drink period: -4.0±0.9 vs -1.7±0.5 in the cow's milk period; p<0.05). Diastolic blood pressure also reduced in the soy drink period (-0.4±0.1 vs 0.4±0.1; p<0.05). CONCLUSION Soy drink replacement could reduce both systolic and diastolic blood pressure among overweight and obese female youths. However, this replacement had no significant results on weight and waist circumference.

Abstract
In this study, the milk-soymilk and milk-soymilk supplemented with Momordica charantia , a common oriental vegetable possessing medicinal activities, were fermented by lactic bacteria. The objective of this study was to investigate the effects of milk-soymilk and fermented milk-soymilk with or without M. charantia on atherosclerosis in hyperlipidemic hamsters. Fermented 25% milk and 75% soymilk combinations, supplemented with 1% M. charantia solution, can improve the acceptability of the fermented beverage. A total of 72 male Golden Syrian hamsters were divided into 9 groups (n = 8/group), and experimental diets were provided with a normal diet for the normal group and a high-cholesterol diet for others. The milk-soymilk and fermented milk-soymilk with or without M. charantia were administrated for 8 weeks. The milk-soymilk and fermented milk-soymilk with and without M. charantia were able to significantly decrease (p < 0.05) the serum cholesterol and the atherosclerotic plaque in aorta based on the comparison to the high-cholesterol diet (H) group. The groups on fermented milk-soymilk by Lactobacillus plantarum NTU 102 with or without M. charantia could significantly decrease (p < 0.05) the ratio of low-density lipoprotein cholesterol (LDL-C) to high-density lipoprotein cholesterol (HDL-C). The femented milk-soymilk by Lactobacillus paracasei subsp. paracasei NTU 101 supplemented with M. charantia had an anti-atherosclerotic activity by increasing superoxide dismutase (SOD) and total antioxidant status (TAS) activity of the blood and relieving the degree of thiobarbituric acid reactive substances (TBARS) compared to the other treatments. It is concluded that the milk-soymilk and the fermented milk-soymilk supplemented with or without M. charantia by L. paracasei subsp. paracasei NTU 101 are effective in preventing and retarding the hyperlipidemia-induced oxidative stress and atherosclerosis.

Abstract
Alternative medicine is a heterogeneous group of treatments which has become increasingly popular in cancer patients in the Western world in recent years. We describe a 77-year-old female with chronic lymphocytic leukemia, who developed severe hyponatremia during treatment with alternative medicine given by a general practitioner over a 3-year-period. From a hematological point of view, there was no need for this expensive treatment as the disease was stable with a normal hemoglobin and thrombocyte count and no B-symptoms. The case illustrates a need for better control of the alternative practitioners and for the adverse reactions to their treatments by the National Health Service.

Abstract
We investigated the effects of consuming an isoflavone aglycone-enriched soya milk containing viable bifidobacteria on urinary isoflavone excretion and percentage recovery. Sixteen postmenopausal women were randomly divided into two groups to consume either fermented or non-fermented soya milk. Each group participated in a double-blind, crossover study with three 14 d supplementation periods, separated by a 14 d washout. Subjects ingested three daily dosages of isoflavone via the soya milk and collected four 24 h pooled urine specimens per supplementation period. Soya milks were prepared with soya protein isolate and soya germ, followed by fermentation with bifidobacteria. Isoflavone levels were quantified using HPLC. Non-fermented soya milks at 20, 40 and 80 mg isoflavone/200 ml contained 10 %, 9 % and 7 % aglycone, respectively, with their fermented counterparts containing 69 %, 57 % and 36 % aglycone (P<0·001). A trend to a greater percentage urinary recovery of daidzein and glycitein was observed among women consuming fermented soya milk at a dosage of 40 mg isoflavone (P=0·13). A distinct linear dose response for the fermented soya milk group (R2=0·9993) compared with the non-fermented group (R2=0·8865) suggested less interindividual variation in isoflavone absorption. However, total urinary isoflavone excretion was similar for both groups (P>0·05), with urinary isoflavone recovery at approximately 31 %. Increasing the isoflavone dosage correlated positively with its urinary excretion, but urinary percentage recovery of isoflavone was inversely related to dosage level. Hence, a modest dosage ranging from 20 to 30 mg/d may provide the most bioavailable source of isoflavone, regardless of whether it is via an aglycone-rich fermented soya milk or a glucoside-rich soya milk.

Abstract
BACKGROUND Artemether-lumefantrine (AL) is the only fixed, artemisinin-based combination antimalarial drug which is registered internationally and deployed on a large scale. Absorption of the hydrophobic lipophilic lumefantrine component varies widely between individuals and is greatly increased by fat coadministration; but patients with acute malaria are frequently nauseated and anorexic, making dietary advice difficult to comply with. The aim of this study was to describe the dose-response relationship between coadministration of fat and relative lumefantrine bioavailability, in order to determine the minimum amount of fat necessary to optimize absorption. METHOD We conducted a multiple crossover pharmacokinetic study in 12 healthy volunteers. This compared the area under the plasma concentration-time curve (AUC) for lumefantrine after administration of a single dose of AL in the fasting state given with 0, 10, 40, 150 and 500 ml of soya milk corresponding to 0, 0.32, 1.28, 4.8 and 16 g of fat. All volumes of milk supplements were tested in all subjects with a 3- to 4-week washout period in-between. RESULTS A dose-response relationship was demonstrated between the volume of soya milk administered and lumefantrine bioavailability. AL administration with soya milk increased the lumefantrine AUC more than five fold. The population mean estimated volume of soya milk required to obtain 90% of maximum effect (in terms of lumefantrine AUC) was 36 ml (corresponding to 1.2 g of fat). CONCLUSIONS Coadministration of artemether-lumefantrine with a relatively small amount of fat (as soya milk) was required to ensure maximum absorption of lumefantrine in healthy adult volunteers.

Abstract
Equol production, isoflavone excretion, and the salivary estradiol profile among 36 females, native Irish Caucasian volunteers following ingestion of 200mL soymilk is reported. The soymilk contained daidzein (73+/-6.7mg) and genistein (86+/-10.2mg). Volunteers provided personal and family medical history. Dietary analysis revealed that all volunteers regularly consumed soy-based or soy-supplemented food products. The mean age, mean age at menarche, and body mass index of volunteers were 46.6+/-12.3 years, 13.1 years and 26.1, respectively. The average number of children per volunteer was 2.13. Twelve (34%) of the volunteers were found to be first-degree relatives of breast cancer patients. Following consumption of the soymilk, equol was detected in the urine of 18 (51%) of the volunteers. Mean urinary daidzein and genistein concentrations during the hours following soymilk ingestion were 13.5 and 16.7microg/mg creatinine, respectively, however, some volunteers excreted little (less than 4.0microg/mg) or no isoflavone. Salivary estradiol in most (24) volunteers had decreased from 51.5+/-28.67pmol/L pre-ingestion to 29.75+/-16.13pmol/L 5h after drinking the soymilk. However, the salivary estradiol in 12 subjects (34%) increased from 33.76+/-13.4pmol/L to 137.4+/-65.64pmol/L over the same period. Individuals whose salivary estradiol increased had significantly less children (1.58 (P<0.05)), were more likely to (a) return urine samples with low isoflavone content (50.3% compared to 25%), (b) to be equol producers (67% compared to 41.7%), and (c) to be first-degree relatives of breast cancer patients (41.7% compared to 25%). Volunteers who reported a first-degree link to breast cancer were more likely to have a higher body mass index (29.0 compared to 26.1 (P<0.05)), to be equol producers (75% compared to 51%), and to excrete isoflavones in low quantities only (60% compared to 50%). First-degree relatives also had fewer children (1.75 (P<0.05)). The results indicate a significant, distinctive variation in equol production, isoflavone excretion and salivary estradiol profile among individual volunteers following ingestion of soymilk.

Abstract
OBJECTIVE To determine whether chicken-based formula can replace soy-based formula in infants with cow milk allergy. SUBJECTS AND METHODS Thirty-eight infants with cow's milk allergy, aged between 2-24 months of age were randomized to receive either chicken-based formula or soy-based formula for 14 days. RESULTS In the group of soy-based formula, 12 out of 18 infants had evidence of intolerance and could not continue with the formula. However, only 4 out of 20 infants in the chicken-based formula group had evidence of clinical intolerance. All other 16 infants were fed the chicken-based formula with success. The number of infants who were intolerant to chicken formula was significantly lower than the number of those fed soy-based formula (p = 0.009). CONCLUSION Chicken-based formula can be used more effectively than soy-based formula in infants with cow milk allergy.

Abstract
OBJECTIVE To present an up-to-date and critical review regarding food allergies, focusing mainly on treatment and prevention. SOURCES Review of published literature searched on MEDLINE database; those data which were the most up-to-date and representative were selected (2000-2006). The search included the European Society of Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) and the American Academy of Pediatrics (AAP). SUMMARY OF THE FINDINGS The prevalence of allergic diseases has increased over the last decades, and food allergy seems to be part of this increase. Food allergy is much more common in pediatrics and has a significant medical, financial and social impact on young children and their families. Treatment and prevention of food allergy is a major challenge for public health, scientific and medical communities. There is a lot of misinformation and the medical management of this condition is still discussable. We present and discuss the guidelines regarding criteria for the prevention of food allergy and atopic diseases published by the Nutrition Committees of ESPGHAN jointly with the European Society for Pediatric Allergy and Clinical Immunology (ESPACI) and AAP. CONCLUSION The overdiagnosis of food allergy is quite prevalent. There is a need for standardization of definitions and diagnostic procedures. The primary goal of therapy should be to first establish effective means of preventing food allergies. There is a need for accurate diagnostic methods to confirm or rule out the diagnosis. Patients need appropriate treatment by eliminating foods that cause symptoms, while avoiding the nutritional side effects and the cost of inappropriate diets.

Abstract
BACKGROUND Allergies and food reactions in infants and children are common and may be associated with a variety of foods including adapted cow's milk formula. Soy based formulas have been used to treat infants with allergy or food intolerance. However, it is unclear whether they can help prevent allergy and food intolerance in infants without clinical evidence of allergy or food intolerance. OBJECTIVES To determine the effect of feeding adapted soy formula compared to human milk, cow's milk formula or a hydrolysed protein formula on preventing allergy or food intolerance in infants without clinical evidence of allergy or food intolerance. SEARCH STRATEGY The standard search strategy of the Cochrane Neonatal Review Group was used. Updated searches were performed of the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 1, 2006), MEDLINE (1966-March 2006), EMBASE (1980-March 2006), CINAHL (1982-March 2006) and previous reviews including cross references. SELECTION CRITERIA Randomised and quasi-randomised trials that compare the use of an adapted soy formula to human milk, an adapted cow's milk or a hydrolysed protein formula for feeding infants without clinical allergy or food intolerance in the first six months of life. Only trials with > 80% follow up of participants and reported in group of assignment were eligible for inclusion. DATA COLLECTION AND ANALYSIS Eligibility of studies for inclusion, methodological quality and data extraction were assessed independently by each review author. Primary outcomes included clinical allergy, specific allergies and food intolerance. Where no heterogeneity of treatment effect was found, the fixed effect model was used for meta-analysis. Where significant or apparent heterogeneity was found, results were reported using the random effects model and potential causes of the heterogeneity were sought. MAIN RESULTS Three eligible studies enrolling high risk infants with a history of allergy in a first degree relative were included. No eligible study enrolled infants fed human milk. No study examined the effect of early, short term soy formula feeding. All compared prolonged soy formula to cow's milk formula feeding. One study was of adequate methodology and without unbalanced allergy preventing co-interventions in treatment groups. One study with unclear allocation concealment and 19.5% losses reported a significant reduction in infant allergy, asthma and allergic rhinitis. However, no other study reported any significant benefits from the use of a soy formula. Meta-analysis found no significant difference in childhood allergy incidence (2 studies; typical RR 0.73, 95% CI 0.37, 1.44). No significant difference was reported in one study in infant asthma (RR 1.10, 95% CI 0.86, 1.40), infant eczema (RR 1.20, 95% CI 0.95, 1.52), childhood eczema prevalence (RR 1.10, 95% CI 0.73, 1.68), infant rhinitis (RR 0.94, 95% CI 0.76, 1.16) or childhood rhinitis prevalence (RR 1.20, 95% CI 0.73, 2.00). Meta-analysis found no significant difference in childhood asthma incidence (3 studies, 728 infants; typical RR 0.71, 95% CI 0.26, 1.92), childhood eczema incidence (2 studies, 283 infants; typical RR 1.57, 95% CI 0.90, 2.75) or childhood rhinitis incidence (2 studies, 283 infants; typical RR 0.69, 95% CI 0.06, 8.00). One study reported no significant difference in infant CMPI (RR 1.09, 95% CI 0.45, 2.62), infant CMA (RR 1.09, 95% CI 0.24, 4.86), childhood soy protein allergy incidence (RR 3.26, 95% CI 0.36, 29.17) and urticaria. No study compared soy formula to hydrolysed protein formula. AUTHORS' CONCLUSIONS Feeding with a soy formula cannot be recommended for prevention of allergy or food intolerance in infants at high risk of allergy or food intolerance. Further research may be warranted to determine the role of soy formulas for prevention of allergy or food intolerance in infants unable to be breast fed with a strong family history of allergy or cow's milk protein intolerance.

Abstract
OBJECTIVE To study the effects of consuming isoflavone aglycone-enriched soymilk fermented by bifidobacteria on urinary excretion of equol with respect to fermentation, daidzein dose, supplementation duration and background diet. DESIGN Double-blind crossover pilot study comprising three 14-day supplementation periods separated by a washout. SETTING Victoria University, Melbourne, Australia. SUBJECTS Sixteen postmenopausal women. INTERVENTION SUBJECTS randomized into two groups consuming either fermented (FS) or non-fermented soymilk (NFS), ingested three daily dosages of daidzein via soymilk and collected pooled urine specimens. Daidzein and equol were quantified using high-performance liquid chromatography. RESULTS After 14-days supplementation six women (38%) excreted equol (>1 micromol equol/day), including four from the FS group, two of whom were classified as non-producers at day 4. Bifidobacteria ingestion, composition of daidzein and its glucosides, and carbohydrate intake appeared to influence equol formation among equol producers. CONCLUSIONS Pilot-study group mean urinary equol excretion results provided insufficient evidence (P>0.05) that FS consumption instigates equol production in women predetermined as non-producers.

Abstract
It is unknown whether the bioavailability of isoflavones is affected by the concomitant ingestion of glucosides or aglycones. This study was designed to investigate the effects of soymilk-based beverages containing different types of isoflavones on their absorption, excretion, and metabolism. Twelve healthy volunteers consumed 3 kinds of soymilk: untreated soymilk, beta-glucosidase-treated soymilk, and fermented soymilk. Blood samples were collected after 0, 1, 2, 3, 4, 5, 6, 7, 8, and 24 h. Urine samples were collected from 0 to 48 h. Concentrations of isoflavones and daidzein metabolites in serum and urine were measured by liquid chromatography-mass spectrometry. After the ingestion of soymilk, the total concentration of isoflavones in serum rose slowly and reached a maximum of 0.94 +/- 0.39 micromol/L at 6.0 +/- 1.2 h. However, beta-glucosidase-treated soymilk and fermented soymilk increased the serum isoflavone concentration significantly more quickly with maximum concentrations at 1.0 h of 1.75 +/- 0.33 micromol/L and 2.05 +/- 0.32 micromol/L, respectively. The urinary excretion of isoflavones after ingesting of these aglycone-enriched preparations was significantly greater than after consumption of untreated soymilk up to 8 h after injection, but not thereafter. The total and individual concentrations of isoflavones in serum and urine did not differ when subjects consumed the 2 aglycone-enriched soymilks. However, in equol producers (n = 5), the ingestion of ESM tended to increase urinary excretion of equol compared with the consumption of FSM (P = 0.08). These results demonstrated that the isoflavone aglycones of soymilk were absorbed faster and in greater amounts than their glucosides in healthy adults and that the metabolism of isoflavones might be affected by the type of soymilk consumed.

Abstract
OBJECTIVE To explore soy intake and urinary isoflavonoid excretion within several generations of American-Japanese women based on the hypothesis that earlier generations excrete higher levels of urinary isoflavonoids, in particular the metabolite equol, than later generations. SUBJECTS A convenience sample of 43 women from 19 families aged 18-78 years, all of whom reported at least 50% Japanese ancestry. INTERVENTIONS Each woman collected overnight urine samples at baseline and after consuming one serving of soymilk, both samples were analyzed for the isoflavonoids daidzein, genistein and equol using liquid chromatography-mass spectrometry. RESULTS Median isoflavone intakes during the last year were 7.2 mg/day for the first generation, 7.3 mg/day for the second generation and 6.3 mg/day for the third generation (P=0.36). At baseline, the median isoflavonoid excretion for the first generation was nonsignificantly higher than for later generations (190, 86 and 42 nmol/h; P=0.20) but after intervention, the median urinary isoflavonoid excretion was very similar for the three groups: 2465, 1895 and 2775 nmol/h (P=0.70). Following intervention, a nonsignificantly higher proportion of older than younger women (53 vs 32 and 33%; P=0.41) excreted the metabolite equol. The respective median equol excretion rates by generation following intervention were 39.5, 4.2 and 3.5 nmol/h (P=0.04). CONCLUSIONS This small investigation among three generations of Japanese-Americans detected a higher equol production among older women after a soy challenge, but no difference in the excretion of total isoflavonoids after a standardized dose of soymilk was observed.

Abstract
Dairy products are the main source of calcium in the National School Lunch Program. Children who avoid dairy products because of lactose intolerance or other concerns can benefit from the availability of another calcium-rich beverage in the National School Lunch Program. This study assessed whether elementary school children would select and consume calcium-fortified soymilk in school cafeterias and whether the addition of soymilk would increase the percentage of students selecting a calcium-rich beverage at lunch. The ratio of saturated fat to calcium consumed from calcium-rich beverages with and without the availability of soymilk was also determined. After 4 weeks of soymilk availability, 22.3% of students chose soymilk and consumed an average of 58% of each carton, whereas 77.6% chose dairy milk and consumed an average of 52.6%. Total calcium-rich beverage selection with lunch increased from 79% to 83.1%. Calcium consumption per gram of saturated fat consumed from calcium-rich beverages also rose from 194 mg to 237 mg with the addition of soymilk.

The objective of this randomized study was to determine if fiber-supplemented soy formula reduced regurgitation in young infants. We compared regurgitation in 179 infants randomly assigned cow's milk-based (CM, 90) formula or soy formula with fiber (SF, 89). Initial daily incidence was similar (CM, 3.6; SF, 3.9 episodes), but significantly lower after 7 days on SF (CM, 3.4; SF, 2.3; p = 0.001). Less frequent regurgitation after 7 days on SF was sustained after 28 days (CM, 48%; SF, 31% of feedings; p = 0.001). Feeding SF effectively managed regurgitation while providing balanced nutrition without altering caloric distribution as occurs with adding rice cereal to formula.

Abstract
BACKGROUND Women with ovarian cancer who experience disease progression during or within 6 months of first-line treatment with platinum-based anticancer drugs are considered to have platinum-resistant tumors. These patients have an unfavorable prognosis, and they frequently seek complementary and alternative therapies (CAM). Historically, this represents an understudied and underreported component of ovarian cancer treatment. CASE This report describes the case of a woman with rapidly progressive, platinum-resistant ovarian cancer. Upon initiating self-directed treatment with Haelan951, a commercially available fermented soy beverage, she entered into a phase of prolonged disease stabilization including improvement in the serum tumor marker CA-125. CONCLUSION Fermented soy products are known to contain high concentrations of the isoflavone, genistein, and other compounds that exhibit anticancer activity in preclinical models. This case report supports the prospective evaluation of alternative therapies such as these in patients with platinum-refractory ovarian cancer.

Abstract
The Chinese diet is low in calcium, including among adolescent girls, with an average intake around 500 mg per day. In this study, we compared the percentage change in bone mineral density and content of the spine and hip region in a 1-year follow-up study between 104 adolescent girls aged 14 to 16 years receiving 375 ml calcium-fortified soymilk supplementation and 95 girls in the control group. The mean percentage changes of bone mineral density/content (BMD/BMC) and standard deviation (SD) at 1 year for the supplementation and control groups were as follows: neck of the femur BMD 2.7+/-2.94%, 1.8+/-3.49% (P = 0.08); trochanter BMD 3.3+/-3.27%, 1.6+/-2.94% (P < or = 0.001); intertrochanter BMD 3.6+/-3.05%, 2.32+/-2.95% (P = 0.002); total hip BMD 3.1+/-2.39%, 2.05+/-2.22% (P = 0.001); total hip BMC 3.8+/-3.05%, 2.6+/-2.96% (P = 0.006). The percent difference between the percentage of bone changes in the supplementation and control groups [100x (soymilk-control)/control] ranged from 45 to 113%. We observed no differences in the spine BMD/C and no differences in changes of height and weight between the soymilk supplementation and control groups, which yielded similar results. Stepwise multivariate regression analysis including height, weight, growth stage, dietary energy, protein, calcium from usual diet and physical activity also showed that supplementation was significantly associated with a percentage increase in BMD/C at the hip. We conclude that 375 ml calcium-fortified soymilk supplementation, or an equivalent of about two glasses, is among the effective strategies for bone acquisition and the optimization of peak bone mass in adolescent girls.

Abstract
OBJECTIVES In view of reports of the growing popularity of soy-based formula for infants, we examined soy consumption and its possible overuse during early infancy in central Israel. METHODS Mothers of 1,803 infants aged 2, 4, 6 and 12 months attending well-baby clinics participated in a telephone survey covering background data, rate, duration, and pattern of soy-based formula use and the reasons for its initiation. The reasons were grouped into those based on the recommendations of the medical personnel and those based on mothers' initiative, and evaluated according to infants' age at soy-based formula initiation (0 to 1, 2 to 4 and 5 to 12 months). The symptoms that prompted soy-based formula use were assessed quantitatively. RESULTS The rate of soy-based formula use was 10.4% at 2 months and 31.5% at 12 months (P<0.001); 70.6%+/- 2.7% of the infants were given soy for>6 months. Regardless of infants' age, the role of the mothers in the decision to use soy-based formula was greater than that of the medical personnel, and increased significantly with age (chi for trend=0.018). A suspicion of cow's milk allergy was responsible for only 10.9% (7/64) of all soy initiations in infants aged 5 to 12 months. In all ages, occasional symptoms, mainly diarrhea (33.3%) and colic (19.8%), were the leading cause for recommending soy-based formula by medical personnel, whereas the personal preference without clinical justification was the leading cause among mothers. CONCLUSIONS The use of soy-based formula in central Israel is extensive and continues for long periods, with rates far beyond clinical indications. Mothers play a greater role than medical personnel in the decision to initiate soy-based formula.

Abstract
The possible neurobehavioral effects of excess manganese in soy formula were studied. Male rhesus monkeys (n=8/group) were fed a commercial cow's milk based formula (Control), a commercial soy protein based formula (Soy), or the soy formula with added manganese (Soy+Mn) from birth to 4 months of age. Soy formulas naturally have higher manganese (Mn) content than cow's milk formulas. Monkeys received behavioral evaluations, growth measurements, and cerebrospinal fluid (CSF) sampling from birth to 18 months of age. Soy and Soy+Mn groups engaged in less play behavior and more affiliative clinging in social dyadic interactions. These groups also had shorter wake cycles and shorter periods of daytime inactivity than controls. An impulsivity test was sensitive to the Soy group diet. The Soy+Mn group also had a blunted response to the dopamine agonist apomorphine. Groups did not differ significantly in CSF dopamine and serotonin metabolite concentrations, but these concentrations were correlated with several tasks affected by experimental formula. This experiment suggests that components of soy formula, including Mn, may influence brain development as reflected in behavioral measures.

Abstract
Prostate cancer has become the most frequently diagnosed male cancer next to non-melanotic skin cancer in the Western world. Preventive measures would therefore have important potential effects on the incidence and prevalence of this disease. A potential for effective prevention of prostate cancer is currently seen in dietary changes and perhaps in dietary supplementation with vitamins D and E or selenium. Pharmacological prevention seems a possibility with drugs acting on intraprostatic testosterone metabolism. Several large randomised trials are ongoing to clarify the potential for successful prostate cancer prevention.

Abstract
Lead concentrations in 82 different types of infant formulae (cow's milk and soy based) marked in Spain were analysed by acid-microwave decomposition and anodic stripping voltammetry. Dietary lead intake from infant formula and tap water used for powder formula reconstitution were estimated in comparison with the provisional tolerable weekly intake (PTWI). Additionally, the influence of physical state (powder and ready-to-use formulae), the type of container used and the impact of the industrial process from different manufacturers on lead levels were evaluated. According to the results, lead exposure from drinking water was negligible with respect to formulae investigated; where soya formulae contributed the highest intake (58-73% PTWI), non-adapted starter and specialized formulae gave an moderate intake (31-42 and 26-37% PTWI, respectively), and, finally, pre-term, adapted starter and follow-up formulae provided the lowest lead intake (22-25, 22-26 and 16-22% PTWI, respectively). Based on the current state of knowledge about lead toxicity, manufacturers are called to make an additional effort in order to keep a maximum lead level at 20 microg l-1 for all infant formulae, although it is recommendable that these formulations supply the upper limit (5 microg l-1) of 'normal' human milk.

Abstract
AIM: To investigate the effect of fermented soy milk on human ecosystem in the intestinal tract by way of examining the population of different microorganisms isolated from fecal samples.
METHODS: A crossover experimental design was applied. Twenty-eight healthy adults completed this experiment. Each subject consumed 250 mL, twice a day between meals, of either fermented soy milk or regular soy milk first for 2 wk, then switched to the other drink after 2 wk. Fecal samples were collected from all subjects every week starting from the second week to the end of the experiment. The microorganisms analyzed were Bifidobacterium spp., Lactobacillus spp., Clostridium perfringens, coliform organisms, and total anaerobic organisms.
RESULTS: In the period of fermented soy milk consumption, the populations of Bifidobacterium spp. and Lactobacillus spp. increased (P<0.05) as well as the ratios of Bifidobacterium spp. and Lactobacillus spp. to Clostridium perfringens (P<0.05). The population of coliform organisms decreased (P<0.05) when subjects were in the period of fermented soy milk consumption.
CONCLUSION: Intake of fermented soy milk significantly improved the ecosystem of the intestinal tract in the body by increasing the amount of probiotics.

Abstract
OBJECTIVE This study investigated the effects of soymilk on lipid metabolism in Sprague-Dawley rats fed a cholesterol-enriched (0.3%) diet. METHODS Thirty male Sprague-Dawley rats weighing 230.0 +/- 9.8 g were randomly assigned to one of three groups: control, S1 (containing 15% soymilk powder in the diet), and S2 (22.5%). After 8 wk, lipid profiles of the plasma, liver, and feces were determined. RESULTS Body weight gain, daily food intake, and feeding efficiency showed no differences across groups (P > 0.05). The experimental groups had significantly lower plasma levels of cholesterol, triacylglycerol, and low-density lipoprotein cholesterol than the control group (P < 0.05) at weeks 4 and 8. However, total fecal excretion of neutral steroid did not significantly differ across groups (P > 0.05). CONCLUSION Soymilk affects the metabolism of plasma cholesterol in Sprague-Dawley rats.

Abstract
The purpose of this study was to explore the feasibility of implementing a soy intervention in female adolescents. Twenty girls, ages 8 to 14, were recruited to consume 1 daily serving of soymilk or soy nuts. They also provided 9 weekly urine samples over a 2-month period. Information about the study foods and procedures was collected through post-study questionnaires. Adherence to the intervention was successful using strategies that addressed both girls' and mothers' needs. The use of conveniently packaged soy foods, activities to maintain motivation, and frequent contact maintained participation. Future studies should also consider the maturity and sense of responsibility of participants to achieve compliance.

Abstract
BACKGROUND Given concerns over the use of hormone replacement therapy (HRT), women are seeking natural alternatives to cope with the symptoms and effects of menopause. The bone sparing effects of soy protein and its isoflavones is well established in animal studies, while 5 previous human studies on soy and bone have yielded variable outcomes due in part to their short duration of study. Progesterone has been suggested as a bone-trophic hormone, but the effect of long-term, low dose transdermal progesterone is unknown. AIM The aim of the study was to compare for the first time the long-term effects of soymilk, with or without isoflavones with natural transdermal progesterone, or the combination, on bone mineral density in the lumbar spine and hip. METHODS Postmenopausal, Caucasian women with established osteoporosis or at least 3 risk-factors for osteoporosis, were randomly assigned, double-blind to one of four treatment-groups: soymilk containing isoflavones (soy+, n = 23), transdermal progesterone (TPD+, n = 22), or the combination of soy+ and TDP+,(n = 22) or placebo (isoflavone-poor soymilk, soy/ and progesterone-free-cream TDP/, n = 22). All subjects received comparable intakes of calcium, minerals and vitamins. Bone mineral content (BMC) and density (BMD) were measured in lumbar spine and hip by using dual-energy X-ray absorptiometry (DEXA) at baseline and after 2 years. FINDINGS The percentage change in lumbar spine BMD and BMC respectively, did not differ from zero in the soy+ group (+1.1%, +2.0%) and TDP+ group (/1.1%, +0.4 %) but significant bone loss occurred in the control group (/4.2%,/4.3 %) and the combined treatment group (/2.8%, /2.4 %). No significant changes occurred for femoral neck BMD or BMC. INTERPRETATION Daily intake of two glasses of soymilk containing 76 mg isoflavones prevents lumbar spine bone loss in postmenopausal women. Transdermal progesterone had bone-sparing effects but when combined with soy milk a negative interaction between the two treatments occurs resulting in bone-loss to a greater extent than either treatment alone.

Abstract
OBJECTIVE This study assessed whether the consumption of soy milk could add significantly to the lipid profile and lipid peroxidation in comparison with non-fat milk. METHODS A double-blind, randomized, crossover study was conducted on 60 outpatients with primary hypercholesterolemia following a lipid-lowering diet for at least 6 wk. Lipid profile was obtained at baseline and at 6 and 12 wk, with the patients randomly assigned to receive initially 1 L/d of soy milk or non-fat cow milk for 6 wk. Lipid peroxidation was estimated by plasma thiobarbituric reactive substances. Apolipoprotein E genotypes were examined by polymerase chain reaction restriction fragment length polymorphism. RESULTS The soy milk diet was associated with low-density lipoprotein cholesterol reduction (baseline = 157 +/- 5 mg/dL; soy milk = 148 +/- 4 mg/dL; non-fat cow milk = 158 +/- 4 mg/dL; P < 0.05, soy milk versus other treatments) and with high-density lipoprotein cholesterol increase (baseline = 58 +/- 2 mg/dL; soy milk = 62 +/- 2 mg/dL; non-fat cow milk = 57 +/- 2 mg/dL; P < 0.05, soy milk versus other treatments). In addition, plasma thiobarbituric reactive substances were reduced by the soy milk diet (baseline = 1.82 +/- 0.12 nM/L; soy milk = 1.49 +/- 0.09 nM/L; non-fat cow milk = 1.91 +/- 0.11 nM/mL; P < 0.05, soy milk versus non-fat cow milk). Changes in lipid profile were not influenced by APOE genotypes. CONCLUSIONS These results indicate that soy milk as part of a lipid-lowering diet has beneficial effects in improving lipid profile and reducing lipid peroxidation.

Abstract
Treatment of female SKH-1 hairless mice with ultraviolet B light twice a week for 20 weeks resulted in a population of tumor-free mice with a high risk of developing skin tumors during the next several months in the absence of additional UVB treatment (high-risk mice). Topical applications of nondenatured soymilk but not heat-denatured soymilk once a day, 5 days a week to these high-risk mice inhibited the formation and growth of skin tumors. Similar topical applications of soybean trypsin inhibitor or Bowman-Birk inhibitor also inhibited the formation and growth of skin tumors, but these agents were less active than nondenatured soymilk. Treatment of miniswine skin with nondenatured soymilk once a day for 5 days prior to UVB irradiation reduced or completely eliminated UVB-induced formation of thymine dimers and apoptotic cells in the epidermis. These data suggest that nondenatured soymilk could be applied to humans to prevent sunlight-induced skin damage and to reduce the risk of skin tumor formation and progression.

Abstract
BACKGROUND Allergies and food reactions in infants and children are common and may be associated with foods including adapted cow's milk formulas. Soy based formulas have been used to treat infants with allergy or food intolerance. However, it is unclear whether they can be advocated for the prevention of allergy and food intolerance in infants without clinical evidence of allergy or food intolerance. OBJECTIVES In infants without clinical evidence of allergy or food intolerance, to determine whether feeding them an adapted soy formula compared to human milk, cow's milk formula or a hydrolysed protein formula prevents allergy or food intolerance. SEARCH STRATEGY The standard search strategy of the Cochrane Neonatal Review Group was used including searches of the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 4, 2003), MEDLINE (1966 - January 2004), EMBASE (1980 - January 2004), CINAHL (1982 - December 2003) and previous reviews including cross references. SELECTION CRITERIA Randomised and quasi-randomised trials that compare the use of an adapted soy formula to human milk, an adapted cow's milk or a hydrolysed protein formula for infant feeding in the first 6 months. Only trials with > 80% follow up of participants and reported in group of assignment were eligible for inclusion. DATA COLLECTION AND ANALYSIS Eligibility of studies for inclusion, methodological quality and data extraction were assessed independently by each reviewer. Primary outcomes included clinical allergy, specific allergies and food intolerance. Meta-analysis was conducted using a fixed effects model where no heterogeneity of treatment effect existed, and a random effects model when heterogeneity was found. MAIN RESULTS Five eligible studies were found, all enrolling infants at high risk of allergy on the basis of a family history of allergy in a first degree relative. All studies compared use of a soy to a cow's milk formula. Two studies also included a group fed a formula containing hydrolysed protein. No eligible study enrolled infants fed human milk. No study examined the effect of early, short term soy formula feeding. Three studies were of good methodology and did not have unbalanced allergy-preventing co-interventions in the treatment groups. Comparing soy to cow's milk formula, one study with unclear allocation concealment and 19.5% losses to follow up reported a reduction in cumulative incidence of childhood allergy, asthma and allergic rhinitis. No other study reported a significant benefit for any allergy or food intolerance. Analysis found no significant difference in allergy cumulative incidence in infancy (one study: RR 1.02, 95% CI 0.69, 1.49) or childhood (3 studies: typical RR 0.73, 95% CI 0.37, 1.44) and no significant difference in cumulative incidence or period prevalence of any specific allergy or food intolerance in infancy or childhood. Analysis of studies comparing soy to a hydrolysed formula found a significant increase in infant (one study: RR 1.67, 95% CI 1.03, 2.69) and childhood allergy cumulative incidence (one study: RR 1.55, 95% CI 1.02, 2.35), infant eczema cumulative incidence (2 studies: typical RR 2.34, 95% CI 1.51, 3.62) and childhood food allergy period prevalence (one study: RR 1.81, 95% CI 1.09, 3.02). REVIEWERS' CONCLUSIONS Feeding with a soy formula should not be recommended for the prevention of allergy or food intolerance in infants at high risk of allergy or food intolerance.

Abstract
Cow's milk allergy (CMA) is an immunologically mediated reaction to cow's milk proteins, which affects infant and young children. Cow milk elimination requires either breast-feeding, with or without elimination diet in mother or the use of specific formulas, based on cow's milk protein extensively hydrolyzed, which fit 90-95% of children with cow's milk allergy. In others, still reactive to allergic remnants in hydrolysates, an amino acid based formula is the optimal option. The good tolerance of soy formulas in a reasonable proportion of children with cow's milk allergy make them useful, including as a 1(st)-choice alternative, except probably for those below the age of 6 months. Any elimination diet in children is at risk of nutritional deficiency so that a constant monitoring of the growth parameters should be kept in those children.
