Executive summary: The role of dairy food intake for improving health among Black Americans across the life continuum. J Natl Med Assoc 2024; 116:211-218. [PMID: 38368232 DOI: 10.1016/j.jnma.2024.01.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Accepted: 01/17/2024] [Indexed: 02/19/2024]
Abstract
Given the complex relationships that many Black individuals have with dairy foods, due to issues with lactose intolerance or other cultural factors, the National Medical Association has made considerable efforts to examine the role that dairy foods play in the health and well-being of Black Americans. Over the last two decades, the National Medical Association and its partners have produced multiple reports on the value of including adequate milk and dairy foods in the diets of Black Americans. These publications have highlighted the impact that inadequate consumption of dairy foods and nutrients have on chronic disease risks. Past publications have also provided evidence-based recommendations for the proper diagnosis and management of lactose intolerance. This new series of evidence reviews focuses on dairy's role in improving nutrition and health among Black Americans across the life course and covers an extensive amount of new research that highlights additional health disparities and provides further evidence-based strategies for the management of lactose intolerance. Much like the 2020-2025 Dietary Guidelines for Americans, this work utilizes a life course approach to better address dairy intake on health outcomes for different ages and life stages: 1) pregnancy, fetal development, and lactation, 2) infants, toddlers, and young children, 3) older children and adolescents, 4) adults, and 5) geriatric populations. Overall, the findings and conclusions from this series of evidence reviews continue to indicate that higher dairy intake is associated with reduced risk for many of the most commonly occurring deficiencies and diseases impacting each life stage, and that Black Americans would receive significantly greater health benefits by increasing their daily dairy intake levels to meet the national dietary recommendations than they would from continuing to fall short of these recommendations. However, these recommendations must be considered with appropriate context and nuance as the intake of different dairy products can have different impacts on health outcomes. For instance, vitamin D fortified dairy products and fermented dairy products like yogurt - which are low in lactose and rich in live and active cultures - tend to show the greatest impacts for reducing disease risk across the life continuum, while whole-fat dairy foods may be most beneficial in early life for optimal brain development, and more protein-rich options may be most beneficial in later life to help maintain muscle mass and function.

Evaluation of a novel stationary phase for the separation of lactose and isomers in lactose-free products using high-performance anion-exchange chromatography coupled with pulsed amperometric detection (HPAEC-PAD). J Chromatogr A 2024; 1716:464661. [PMID: 38246068 DOI: 10.1016/j.chroma.2024.464661] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Revised: 01/12/2024] [Accepted: 01/14/2024] [Indexed: 01/23/2024]
Abstract
Lactose intolerance is a widespread condition, which prevents a large number of people from consuming dairy products as a part of their daily diet. It is estimated that an average of 65% of the global population is suffering from lactose intolerance. The global market for 'lactose-free' dairy products is rapidly growing and the criteria for 'lactose-free' labelled products are becoming stricter. To check the lactose contents in these products there is a need for fast, sensitive, and selective analytical method. A method is presented for fast and sensitive determination of lactose and its isomers using High-Performance Anion Exchange Chromatography in combination with Pulsed Amperometric Detection (HPAEC-PAD). The use of a new anion-exchange column, SweetSep™ AEX200, which is a strong anion-exchange column with highly monodisperse 5 µm particles, allowed the separation of all compounds of interest in less than 8 min with high resolution. A variety of dairy products were analyzed to demonstrate the versatility of the method.

Abstract
Lactose intolerance affects about 68-70% of the world population and bovine whey protein is associated with allergic reactions, especially in children. Furthermore, many people do not consume dairy-based foods due to the presence of cholesterol and ethical, philosophical and environmental factors, lifestyle choices, and social and religious beliefs. In this context, the market for beverages based on pulses, oilseeds, cereals, pseudocereals and seeds and products that mimic dairy foods showed a significant increase over the years. However, there are still many sensory, nutritional, and technological limitations regarding producing and consuming these products. Thus, to overcome these negative aspects, relatively simple technologies such as germination and fermentation, the addition of ingredients/nutrients and emerging technologies such as ultra-high pressure, pulsed electric field, microwave and ultrasound can be used to improve the product quality. Moreover, consuming plant-based beverages is linked to health benefits, including antioxidant properties and support in the prevention and treatment of disorders and common diseases like hypertension, diabetes, anxiety, and depression. Thus, vegetable-based beverages and their derivatives are viable alternatives and low-cost for replacing dairy foods in most cases.

Does the peroral chromium administration in young Hariana calves reduce the risk of calf diarrhea by ameliorating insulin response, lactose intolerance, antioxidant status, and immune response? J Trace Elem Med Biol 2023; 80:127313. [PMID: 37801788 DOI: 10.1016/j.jtemb.2023.127313] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Revised: 09/20/2023] [Accepted: 09/21/2023] [Indexed: 10/08/2023]
Abstract
BACKGROUND The reduction in insulin sensitivity during rumen development may predispose dairy calves towards lactose intolerance, which could be the reason behind neonatal calf diarrhea (NCD). Chromium (Cr) results in a range of effects when fed to ruminants, but most studies have shown improved insulin sensitivity. The aim of this study was to determine the effect of Cr supplementation on insulin sensitivity, lactose intolerance, diarrhoea and antioxidant, and immune response in young Hariana calves. METHODS A total of 20 milk-fed Hariana calves were randomly assigned to 1 of 2 treatments, each consisted of 10 calves: (1) a control group without supplemental Cr and (2) a 0.15 mg Cr as Cr-picolinate (CrPic)/kg BW0.75 supplemented group (Cr0.15). RESULTS A more rapid glucose disappearance with unaltered insulin kinetics during intravenous glucose tolerance test (IVGTT) and oral lactose tolerance test (OLTT) indicates greater insulin sensitivity in Cr supplemented calves. Better insulin sensitivity in Cr supplemented calves was further confirmed by higher values of the quantitative insulin sensitivity check index (QUICKI), revised quantitative insulin sensitivity check index (RQUICKI) and insulin receptor substrate-1 (IRS-1) and lower (P < 0.05) values of homeostasis model assessment-insulin resistance (HOMA-IR) and glucose-to-insulin ratio in Cr supplemented calves during IVGTT. Cr supplementation resulted in a lower (P < 0.05) serum cortisol concentration, whereas serum non-esterified fatty acid (NEFA) concentrations during IVGTT did not differ among the groups. The rise in serum glucose concentrations within 2 h post lactose infusion during OLTT peaked at more than twice the basal glucose concentration, therefore calves were not considered as lactose intolerant. Within monthly blood samples, concentrations of serum insulin were similar among treatments, whereas the Cr supplemented group had lower (P < 0.05) serum glucose concentration and glucose-to-insulin ratio compared with the control group. No treatment differences were detected in the biomarkers of antioxidant status and immunity. Serum Cr concentrations were higher (P < 0.05) in Cr supplemented calves while concentrations of other studied minerals were remained unaltered. The incidence, duration of diarrhea, and faecal score were better (P < 0.05) in calves fed on Cr supplemented diet whereas, no treatment effect was observed on average daily gain (ADG). During the study period, no calves died, and no calves were found to have pneumonia, navel or joint disease. CONCLUSION Feeding a Cr-supplemented diet improved insulin sensitivity and reduced the risk of diarrhoea in milk-fed young calves, but had no or minimal effects on lactose intolerance, antioxidant status, immune response, and growth performance.

Abstract
Studies have found that exclusive breastfeeding can not only promote the growth and development of infants, but also increase the emotional communication between mothers and infants, and reduce the incidence of maternal breast diseases. To analysis the current situation and influencing factors of breastfeeding twins. A total of 420 twin mothers delivered in our hospital from January 2019 to December 2022 were selected to investigate the situation of breastfeeding within 6 months after delivery. An electronic questionnaire was conducted, and clinical information were collected. Univariate analysis and multivariate logistic regression analysis were applied to analyze the factors influencing exclusive breastfeeding. The rate of exclusive breastfeeding was 21.90%; in the exclusive breastfeeding group, the age <35 years old, bachelor degree or above, rural areas, no nipple depression or flat, no breast distension, no postpartum depression, adequate breast milk, participation in health education during pregnancy, husband support for breastfeeding, no infant feeding difficulties, infant diarrhea, lactose intolerance and return to milk were 96.74%, 53.26%, 65.22%, 80.43%, 76.09%, 80.43%, 73.91%, 63.04%, 69.57%, 71.74%, 65.22%, 70.65%, and 66.30%, respectively. It was significantly higher than that in the non-exclusive breastfeeding group (P < .05). The score of Edinburgh Postpartum Depression Scale (EPDS) was (8.08 ± 1.03) in the exclusive breastfeeding group, which was significantly lower than that in the non-exclusive breastfeeding group (P < .001), while the score of Perceived Social Support Scale (PSSS) was (67.32 ± 9.92), which was significantly higher than that in the non-exclusive breastfeeding one(P < .001). Logistic regression analysis showed that age, education level, nipple depression or flat, breast tenderness, postpartum depression, breast milk volume, health education training during pregnancy, husband support for breastfeeding, PSSS score, infant diarrhea, lactose intolerance, and delectation were the influencing factors of exclusive breastfeeding (P < .001). Our findings suggest that various factors were associated with a low rate of exclusive breastfeeding in twin births, such as age, educational level, and social support. Corresponding measures should be formulated for intervention to promote exclusive breastfeeding.

Abstract
The widespread consumption of plant-based drinks, driven by health and dietary reasons (including cow's milk allergy, lactose intolerance, milk protein intolerance, following a vegetarian or vegan diet) necessitates automated and accurate test methods. Our study demonstrates the simultaneous determination of protein components and total protein concentrations in plant-based milk alternatives using a rapid and reproducible microchip gel electrophoretic method. As expected, the electrophoretic profiles of each plant-based drink differed. Based on our analyses and statistical evaluation, it can be determined that the protein profiles of different plant-based beverages do not differ significantly between different manufacturers or different expiry dates. The measured total protein content was compared with the nominal values, i.e., the values stated on the beverage labels. As the number of consumers of functional and specialized plant-based milk alternatives continues to rise, it is important to prioritize methods that provide qualitative and quantitative information on protein composition and other nutrients.

Associations of Food Intolerance with Irritable Bowel Syndrome, Psychological Symptoms, and Quality of Life. Clin Gastroenterol Hepatol 2022; 20:2121-2131.e3. [PMID: 34952206 PMCID: PMC9209586 DOI: 10.1016/j.cgh.2021.12.021] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Revised: 12/07/2021] [Accepted: 12/09/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS The impact of different types of food intolerance on gastrointestinal symptoms and quality of life (QOL) is poorly understood. We aimed to investigate associations of food intolerance and type of intolerance with irritable bowel syndrome (IBS), health-related QOL, and psychological symptoms. METHODS We conducted an observational study of United States-based adults through an online survey. Demographics, culprit foods, symptoms, medical evaluation, Rome IV criteria for IBS, health-related QOL (Short-Form Health Survey 12), and anxiety and depression scores (Hospital Anxiety and Depression Scale) were collected in participants with self-reported food intolerance (lactose, non-lactose food, lactose plus food intolerance), and controls with no intolerance. Univariable associations of group with study endpoints were analyzed with the Kruskal-Wallis and Pearson χ2 or Fisher exact test. Multivariable comparisons were analyzed by logistic and linear regression. RESULTS A total of 197 patients with (59 lactose, 61 non-lactose food, 77 lactose plus food intolerance) and 273 patients without intolerance participated. Lactose, wheat, and eggs were the most common food triggers. Gas (54.2%), abdominal pain (40.2%), and diarrhea (37.3%) were frequently reported symptoms of food intolerance. Reactions caused 57.8% to eliminate the food. Rates of IBS, abnormal anxiety scores, and abnormal depression scores were highest in lactose plus food intolerance; Short-Form Health Survey 12 scores were lowest in lactose plus food intolerance. Multivariable analyses revealed all intolerance subgroups were more likely to have IBS than controls. CONCLUSIONS Food intolerance is associated with IBS, anxiety, depression, and decreased health-related QOL and frequently leads to food elimination. Adults with lactose and lactose plus food intolerance have higher rates of IBS, increased psychological symptoms, and poorer QOL.

Abstract
We describe a case of a 38-year-old woman who, after radioactive iodine therapy for Graves' disease, developed severe hypothyroidism despite receiving a high dose of levothyroxine (L-T4) tablet as replacement therapy. Her thyroid stimulating hormone (TSH) remained to be high despite the dose of L-T4 tablets to 400 μg/day after treatment for hypothyroidism, and the patient complained of general malaise and edema of the legs. Reduced intestinal absorption of L-T4 is the most common cause of failure to achieve the therapeutic target in hypothyroid patients receiving replacement therapy. She was admitted to our hospital for severe hypothyroidism due to resistance to treatment with L-T4 tablet. Our patient was found to have lactose intolerance (LI) by a detailed examination during hospitalization. Therefore, we assumed that LI was impairing intestinal absorption of L-T4 tablet in our patient, leading to severe hypothyroidism. The patient was switched to the powder formulation of L-T4 at the same daily dose, and serum levels of thyroid-stimulating hormone and thyroid hormones normalized. This is the case in which hypothyroidism due to reduced absorption of L-T4 tablet in a patient with LI was resolved by switching to L-T4 powder formulation.

Abstract
Beverages can provide improved nutrient intake and hydration, but also pose concerns related to overnutrition or contamination for children and adolescents who are in a time of critical growth. This narrative review aims to understand the impact of milk, 100% juice, and water consumption on health-related outcomes in youth. The literature review conducted used PubMed, Web of Science, and CABI global. Forty-five research articles met the quality criteria and were included. Health organization and governmental resources were also reviewed to identify current intake and consumption recommendations. All beverages in this review were associated with a variety of desirable and undesirable findings that spanned over 40 different health outcomes. Most studies that assessed milk lacked clear distinction between milk type (flavored vs. unflavored) or fat percentage, making it difficult to understand the impact of milk consumption. The relationship between milk intake and anthropometric-related outcomes were mixed within and across studies. Water was consistently associated with better hydration, while 100% juice and flavored milk intake was associated with more desirable dietary patterns or nutrients that children are currently not consuming adequate amounts of. The implications of these findings were discussed in the context of the National School Lunch Program (NSLP), while considering the impact of issues such as contaminated water and lactose intolerance. This review suggests that water may be an optimal default beverage option in the NSLP to promote hydration and accommodate beverage preferences for those with lactose intolerance.

The challenges of implementing low fermentable oligo-, di-, mono-saccharides and polyol diet in India: An analysis of available data. Indian J Gastroenterol 2022; 41:104-113.

Abstract
BACKGROUND Low fermentable oligo-, di-, monosaccharides, and polyols (FODMAP) diet is used in irritable bowel syndrome (IBS). However, data on the utility and challenges of implementing such a diet in India are scanty. Since dietary practices in India are different from other Asian and Western countries, the existing Indian data were analyzed. METHODS This study attempted to analyze the existing Indian data on the frequency of vegetarianism, cereal (wheat vs. rice), milk/milk product consumption, and lactose malabsorption (LM). A 5-point scale (quiet easy, easy, moderately easy, not easy, difficult) for implementation of low FODMAP diet for IBS patients was proposed based on regional dietary diversity and LM in India. RESULTS Our analysis showed that vegetarianism is high in India with regional differences in frequency. Similarly, there is regional variation in frequency of LM though it is quite high in most parts of India where data are available. While southern, eastern, and north-eastern [corrected] parts of the country have rice as the staple cereal, wheat is consumed more in other parts. We suggest that implementing a low FODMAP diet in north-eastern India may be most easy compared to northern India, where it may be most difficult. Implementing a low FODMAP diet in southern and eastern India may be easy, moderately easy in western India, and not easy in central India. CONCLUSIONS The variation in the difficulty in implementing a low FODMAP diet in India may stem from the regional food preference and differences in vegetarianism, as well as frequency of LM.

Abstract
The C/T-13910 LCT is closely associated with lactase persistence and LCT has emerged as a new candidate gene for obesity, in particular in northern Europeans. The aim of this research is to investigate to what degree sex determines the association between the LCT variant and anthropometric traits in a cohort of healthy individuals. We recruited 1000 (500 males and 500 females aged 18-65 years) healthy blood donors. The C/T-13910 LCT polymorphism was genotyped using TaqMan assays. All individuals were phenotyped with respect to anthropometric characteristics. Prevalence of genotypes was 22.7% CC (lactase non-persistent, LNP), 58.6% CT, and 18.7% TT. LNP genotype was present less frequently among men p = .0005; OR 0.582 [0.425-0.794]. Therefore, in addition statistical calculations were performed separately for men and women. Additional analysis demonstrated an association between the CC genotypes and higher chest (p = .03), waist (p = .005), and forearm circumference (p = .0004) or more lean body mass (p = .04), than T-allele carriers in males. In females, they were not significantly different. Men consumed more milk (p = .003), while women ate more yoghurt (p = .001). Pearson's correlation analysis showed that the higher intake of milk and dairy products was associated with higher fat body mass among men with lactase persistence. In Caucasian men, the LNP genotype is associated with reduced milk intake and dairy products, but more fat-free mass and higher forearm circumference, which may be relevant to dietary management for lactose intolerant.

Abstract
Metabolism changes play a key role in many mammalian diseases such as decreasing bone mineral density, osteoporosis, digestive disorders. Lactose intolerance is found in 75% of the in human world's population. The aim of this study was evaluation of the genetic aspects of lactase deficiency in different ethnic groups and its relation with pathologies of bone tissue and gastrointestinal tract. The world data of lactose tolerance, hip fracture incidence, digestive diseases were derived from websites the International Osteoporosis Foundation and World Health Organization. Statistical analysis was carried out by Shapiro-Wilk test, Spearman correlation. An analysis of the world population showed that the lactose tolerance parameters have a statistically significant positive correlation with the hip fractures frequency (r=0.656) and a negative correlation with digestion diseases mortality (r=-0.577). An important factor in the pathologies prevention is the diet correction taking into account the phenotype and genotype of lactose tolerance.

Abstract
PURPOSE A variety of enteral formulas for various diseases have become available in India in the last few years. Awareness among pediatricians about the availability and indications for these therapeutic formulas is low. METHODS A literature search was conducted in PUBMED and relevant data collected from all English language publications available. Data on the commercial preparations was sourced from the individual companies, the Diet 4 life initiative as well as FSSAI (Food safety and standards authority of India). CONCLUSIONS Therapeutic enteral formulas, which are indicated in various disease states belong to four categories - lactose modified, hydrolyzed, MCT based and metabolic disease specific formulas. Lactose modified formulas which are used in temporary or permanent lactose intolerance and Galactosemia are either casein or soy protein based. Hydrolyzed formulas could be partially hydrolyzed, extensively hydrolyzed or amino acid based. Only extensively hydrolyzed formula should be recommended in milk protein allergy. Amino acid (elemental) formulas are mainly indicated in patients with diffuse intestinal mucosal disease. MCT formulas are used in chronic liver disease with cholestasis, and have 30 to 80% MCT. Formulas for inborn errors of metabolism are free of specific carbohydrate, amino acid or fatty acid. Proprietary formulas presently available in India with their specifications have been listed.

The Importance of Lactose in the Human Diet: Outcomes of a Mexican Consensus Meeting. Nutrients 2019; 11:E2737.

Abstract
Lactose is a unique component of breast milk, many infant formulas and dairy products, and is widely used in pharmaceutical products. In spite of that, its role in human nutrition or lactose intolerance is generally not well-understood. For that reason, a 2-day-long lactose consensus meeting with health care professionals was organized in Mexico to come to a set of statements for which consensus could be gathered. Topics ranging from lactase expression to potential health benefits of lactose were introduced by experts, and that was followed by a discussion on concept statements. Interestingly, lactose does not seem to induce a neurological reward response when consumed. Although lactose digestion is optimal, it supplies galactose for liver glycogen synthesis. In infants, it cannot be ignored that lactose-derived galactose is needed for the synthesis of glycosylated macromolecules. At least beyond infancy, the low glycemic index of lactose might be metabolically beneficial. When lactase expression decreases, lactose maldigestion may lead to lactose intolerance symptoms. In infancy, the temporary replacing of lactose by other carbohydrates is only justified in case of severe intolerance symptoms. In those who show an (epi)genetic decrease or absence of lactase expression, a certain amount (for adults mostly up to 12 g per portion) of lactose can still be consumed. In these cases, lactose shows beneficial intestinal-microbiota-shaping effects. Avoiding lactose-containing products may imply a lower intake of other important nutrients, such as calcium and vitamin B12 from dairy products, as well as an increased intake of less beneficial carbohydrates.

Lower Gastrointestinal Conditions: Malabsorption Syndromes. FP ESSENTIALS 2019; 483:20-24. [PMID: 31411845] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/10/2023]
Abstract
Malabsorption syndromes are common in family medicine but may be overlooked because of a wide variation in presentation. Classic symptoms include diarrhea, steatorrhea, weight loss, flatulence, and postprandial abdominal pain. Nongastrointestinal manifestations can include elevated levels of liver function markers, anemia, skin conditions, infertility, and bone disease. Associated conditions include lactose intolerance, celiac disease, and exocrine pancreatic insufficiency. Testing should include screening for anemia. A standard test for lactose intolerance is the hydrogen breath test; however, formal testing typically is not required for diagnosis. The diagnosis of celiac disease depends on serologic testing, histologic findings on duodenal biopsy, or both. Patients should not restrict their diets before testing for malabsorption syndromes. If the initial evaluation is negative for celiac disease, other conditions should be considered, including nonceliac gluten sensitivity, irritable bowel syndrome, and fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) intolerance. Therapies for patients with malabsorption syndromes involve dietary modification. A lactose-restricted diet and use of dairy substitutes are recommended for lactose intolerance. A gluten-free diet is the primary intervention for celiac disease. Pancreatic enzyme replacement therapy and replacement of fat-soluble vitamins are the primary therapies for management of exocrine pancreatic insufficiency.

Abstract
The objective of the present study was to elucidate the possible correlations between the vitamin D3 level in the blood serum and lactase gene polymorphism (LCT-13910 T>C) in the patients presenting with chronic polypous rhinosinusitis (CPRS). The study included 50 patients with this condition and 14 subjects comprising the control group. The variants of lactase gene polymorphism (LCT-13910 T>C) were identified with the use of polymerase chain reaction (PCR) in real time. The total level of serum vitamin D3 (VD3) was determined by means of the immunochemical analysis (the electrochemiluminescence technique). In the group of patients presenting with chronic polypous rhinosinusitis, the level of VD3 in the blood serum ranged from 48 nm/l to 85 nm/l (mean 60 nm/l) compared with that in the patients of the control group (from 78 nm/l to 112 nm/l; mean 97 nm/l) . The level of vitamin D3 'below the normal values' was documented in 71% of the patients with CPRS in comparison with 7% in the control subjects. Lactase gene polymorphism (LCT-13910 CC, CT) suggesting pronounced and latent hypolactasia was identified in 94% of the patients with CPRS compared with 78.6% in the control group. The occurrence of the CC genotype in the patients of both study groups was virtually identical: 52% in the patients presenting with chronic polypous rhinosinusitis and 57% in the control group. CT polymorphism was identified in 42% of the patients with CPRS and in 21% of the control subjects. The significant difference between the patients of the two groups was documented for the occurrence of TT polymorphism: 6% among the patients with CPRS and 21% in the controls (i.e. much higher in the healthy subjects). There was no significant difference between the serum levels of vitamin D3 either among the patients with CPRS having LCT-13910 gene polymorphisms (CC, CT, TT) or among the control subjects. It is concluded that the study revealed the higher levels of vitamin D3 in the blood sera from the control subjects in comparison with that in the patients with chronic polypous rhinosinusitis. Moreover, the patients of the latter group more frequently exhibited the variant of the LCT CT-13910 gene polymorphism suggesting latent hypolactasia whereas the subjects comprising the control group more frequently had the variant of the LCT CT-13910 gene polymorphism indicative of the normal tolerance of lactose.

Abstract
OBJECTIVE To investigate the effects of milk with inulin and vitamin D3 on bone health and gastrointestinal symptoms in lactose intolerance( LI) population. METHODS A total of 42 volunteers diagnosed as LI by breath hydrogen test were randomized into A or B group. Whole milk supplemented with inulin( 150 mg /100 g), vitamin D3( 2. 0μg /100 g), casein phosphopeptides( 5. 0 mg /100 m L), milk minerals( 40 mg /100 g), and low-lactose whole milk were given to A or B groups respectively. Bone mass density( BMD), calcium absorption and gastrointestinal symptoms were measured at the 0th and6 th week of the intervention. RESULTS After 6 weeks, BMD increased significantly in group A( P = 0. 013). In group B, BMD also increased but the trend was not significant. Calcium absorption increased in group A but decreased slightly in group B, the trends in both groups lacked of statistic significant. Gastrointestinal symptoms were ameliorated in both groups, but still there was no significance. For all the measurements, there was nostatistic significant difference between groups. CONCLUSION Milk with inulin and vitamin D3 could improve bone health in LI population, gastrointestinal symptoms after drinking this certain milk were analogous to low lactose milk.

Abstract
The prevalence of symptomatic adverse reactions to gluten and adherence to gluten-free diet in Latin American countries is unknown. These measurements are strongly linked to gluten-related disorders. This work aimed to estimate the prevalence of adverse reactions to oral gluten and the adherence to gluten-free diet in the adult Mexican population. To reach this aim, a self-administered questionnaire was designed and tested for clarity/comprehension and reproducibility. Then, a self-administered questionnaire-based cross-sectional study was conducted in the Mexican population. The estimated prevalence rates were (95% CI): 11.9% (9.9–13.5) and 7.8 (6.4–9.4) for adverse and recurrent adverse reactions to gluten respectively; adherence to gluten-free diet 3.7% (2.7–4.8), wheat allergy 0.72% (0.38–1.37); celiac disease 0.08% (0.01–0.45), and NCGS 0.97% (0.55–1.68). Estimated pooled prevalence of self-reported physician-diagnosis of gluten-related disorders was 0.88% (0.49–1.5), and 93.3% respondents reported adherence to gluten-free diet without a physician-diagnosis of gluten-related disorders. Symptom comparisons between those who reported recurrent adverse reactions to gluten and other foods showed statistically significant differences for bloating, constipation, and tiredness (p < 0.05). Gluten-related disorders may be underdiagnosed in the Mexican population and most people adhering to a gluten-free diet are doing it without proper diagnostic work-up of these disorders, and probably without medical/dietician advice.

Abstract
Objectives Knowledge about the prevalence of allergies to foods in childhood and adolescence is incomplete. The purpose of this study was to investigate the prevalence of allergies to milk, egg, cod, and wheat using reported data, clinical examinations, and double-blind placebo-controlled food challenges, and to describe the phenotypes of reported food hypersensitivity in a cohort of Swedish schoolchildren. Methods In a population-based cohort of 12-year-old children, the parents of 2612 (96% of invited) completed a questionnaire. Specific IgE antibodies to foods were analyzed in a random sample (n=695). Children reporting complete avoidance of milk, egg, cod, or wheat due to perceived hypersensitivity and without physician-diagnosed celiac disease were invited to undergo clinical examination that included specific IgE testing, a celiac screening test, and categorization into phenotypes of food hypersensitivity according to preset criteria. Children with possible food allergy were further evaluated with double-blind challenges. Results In this cohort, the prevalence of reported food allergy to milk, egg, cod, or wheat was 4.8%. Food allergy was diagnosed in 1.4% of the children after clinical evaluation and in 0.6% following double-blind placebo-controlled food challenge. After clinical examination, children who completely avoided one or more essential foods due to perceived food hypersensitivity were categorized with the following phenotypes: allergy (29%), outgrown allergy (19%), lactose intolerance (40%), and unclear (12%). Conclusions There was a high discrepancy in the prevalence of allergy to milk, egg, cod and wheat as assessed by reported data, clinical evaluation, and double-blind food challenges. Food hypersensitivity phenotyping according to preset criteria was helpful for identifying children with food allergy.

Abstract
OBJECTIVE To determine whether a 21-day milk-drinking intervention could reverse milk aversion. DESIGN Participants consumed increasing amounts of cow's milk for 21 days. Milk and dairy consumption, aversion, and likeness were assessed pre- and post-intervention and at 3 and 6 months post-intervention. SETTING A large Midwestern university. PARTICIPANTS Twenty-seven milk-averse individuals completed the intervention, 26 completed the 3-month follow-up, and 24 completed the 6-month follow-up. MAIN OUTCOMES MEASURED Participants self-reported milk and dairy consumption, aversion, and degree to which they liked milk. ANALYSIS Analysis of variance determined between-subject effects. Independent samples t test determined the effect of time. Fisher exact test determined factors affecting milk consumption. RESULTS Lactose digesters and maldigesters showed a significant decrease in overall symptom scores after the milk intervention, with no significant difference between groups. Independent of digestive status, subjects demonstrated a significant decrease in aversion, an increase in the amount to which they liked milk, and an increase in milk and overall calcium consumption at 3 and 6 months post-intervention. CONCLUSIONS AND IMPLICATIONS The results suggest a reversal of milk avoidance and the possibility that milk avoiders can increase likeness and incorporate milk into their diet after exposure.

Abstract
The new guideline on irritable bowel syndrome (IBS) advocates distinguishing IBS patients who predominantly suffer from constipation from those who mainly suffer from diarrhoea or from alternating bouts of diarrhoea and constipation. In the latter two groups, coeliac disease should be excluded, as should lactose intolerance if at all possible. Since there is no gold standard for the treatment of IBS a thorough explanation of the condition to patients is recommended.

Abstract
Lactose intolerance is a common condition caused by intestinal lactase deficiency, and a lactose-free diet represents the simplest way to avoid gastrointestinal symptoms. The emerging use of dietary supplements requires analytical tools that are capable of assessing these analytes, particularly for those based on dry herbal extracts that contain lactose together with maltose and sucrose, because of cross-contamination and/or deliberate addition as excipient. Electrospray ionization mass spectrometry (ESI-MS) and MS/MS are valuable detection methods for underivatized disaccharides; however, the absence of distinctive ions and collision-induced dissociation (CID) fragmentation patterns does not allow discrimination of stereoisomers without good chromatographic resolution. We developed an ultrahigh performance liquid chromatography-ESI (U-HPLC-ESI) approach, based on porous graphitic carbon (PGC) columns, working at 5 °C to separate and detect the disaccharides in their anomeric forms as formate adducts obtained directly in-column by eluting with formate buffer/acetonitrile gradient mixtures. Using a Paul trap, we monitored the adducts [M + HCOO](-) at m/z 387 in ESI negative mode (MS(1)) as well as the CID fragment ion [M - H](-) at m/z 341 (MS(2)) and used MS(3) fragment ions at m/z 178 and 161 to confirm disaccharides identity in complex vegetable matrices. Complete resolution of lactose α- and β-anomers, maltose α- and β-anomers, and sucrose was obtained with R ≥ 2.0 for all peaks and selectivity α = 1.2 between α- and β-anomers of lactose. The limits of detection were in the range of 3-7 µg/l (ppb) for the target disaccharides. Because of the rapidity and good anomeric discrimination, the described method represents an alternative tool to investigate the mutarotation phenomenon for reducing disaccharides.

Abstract
OBJECTIVE To determine whether camel's milk can be consumed by patients intolerant to lactose without undesirable reactions. PATIENTS AND METHOD Twenty-five patients with clinical and laboratorial diagnosis of lactose intolerance underwent provocation tests with growing amounts of cow's milk and subsequently with camel's milk. RESULTS Except for two patients, who had mild reactions to the maximum dosage of camel's milk (250 mL), the acceptance was excellent. Pasteurization of camel's milk did not affect tolerance. Also, most of the patients showed significant clinical reactions when drinking very low amounts of cow's milk. CONCLUSION Camel's milk can be considered an option for the individuals intolerant to lactose who present symptoms when ingesting cow's milk.

Abstract
BACKGROUND The contribution of specific foods to the genesis of symptoms in irritable bowel syndrome (IBS) has been increasingly recognised in recent years. OBJECTIVE This article discusses the dietary triggers for IBS and the role of diagnostic testing in patients with IBS. DISCUSSION In addition to the long standing implication of lactose in lactase deficient patients, fermentable dietary oligosaccharides, disaccharides, monosaccharides and polyols, together with very low carbohydrate diets, have been increasingly recognised as important in the causation and treatment of irritable bowel syndrome. Understanding their role and utilising the services of a practising dietician have become additional important tools for general practitioners managing this common complaint.

Abstract
OBJECTIVE A large body of evidence supports a role for soy in the management of type 2 diabetes. However, little is known about the current consumption, perceptions and knowledge of soy among those living with type 2 diabetes. The purpose of this research was to explore the consumption, perceptions and knowledge of soy among adults with type 2 diabetes. METHODS A total of 202 adults with type 2 diabetes completed a detailed questionnaire designed to gather data about soy consumption, motivations for consuming soy, purchase locations for soy, methods of obtaining information about soy, barriers to soy consumption, as well as general health/lifestyle, medical and demographic information. RESULTS Soy consumers were significantly more likely to be vegetarian, lactose intolerant and avoid cow's milk and significantly less likely to take medications, when compared to soy non-consumers. There were no significant differences between soy consumers and soy non-consumers in factors related to diabetes management. The prevalence of soy consumption was 19% and the majority of soy was consumed on a weekly basis and most often at breakfast. The three most commonly consumed soy products were soy beverage, tofu and roasted soy nuts and they were purchased most often from the grocery store. Soy consumers were significantly more aware of soy's potential health benefits, compared to soy non-consumers. More than half (63.8%) of soy non-consumers had consumed soy in the past and the top reason for no longer consuming soy was 'dislike taste, texture or appearance'. The most commonly reported barriers to soy consumption were being unsure of how to prepare soy, taste and texture. CONCLUSIONS Although soy consumption was not predictive of factors related to diabetes management, valuable information was generated regarding patterns of soy consumption, motivations for and barriers to soy consumption, beliefs and knowledge about soy, and most common sources of information about soy. This information will be useful to numerous stakeholders including those who produce, market and sell soy, as well as those who disseminate health information about soy.

Abstract
We report the clinical course of a case of X-linked lissencephaly with absent corpus callosum and abnormal genitalia (XLAG) exhibiting severe diarrhea. The patient demonstrated lactose intolerance and his intractable seizures were relieved with lactose-free, extensively hydrolyzed whey protein formula. At the age of 2 years while being treated with the antiallergic formula, he was affected with severe diarrhea that resembled watery diarrhea-hypokalemia-acidosis syndrome (WDHA). Administration of octreotide was effective in relieving his secretory diarrhea. Hypoglycemia without hyperinsulinemia was seen during fasting, and plasma vasoactive intestinal polypeptide was not increased when he had WDHA-like diarrhea. Although pancreas of ARX mutant mice revealed an increased number of beta and delta cells, we did not detect the cause of hypoglycemia and secretory diarrhea by pancreatic endocrinology. His urinary findings mimicked the symptoms of Fanconi syndrome, so it was possible that his hyperaldsteronemia affected not only his intestinal tract, but also his renal tubules.

Abstract
PURPOSE OF REVIEW The high-nutrient needs of children for normal growth and development are matched by ready access to low-nutrient high-energy foods. Parents are often confused by new and at times conflicting information. This review discusses three recently published papers that offer specific and important dietary information for school-aged children. RECENT FINDINGS Lactose intolerance is common in some populations and there are misconceptions about dairy intake. Most lactose-intolerant children can consume some dairy products without symptoms. Fruit-juice intake can predict increased weight gain in children, especially those who are already overweight or at risk for being overweight. Hypertension is a serious disease with onset likely in childhood. This paper discusses the importance of dietary sodium as a contributor to the development of hypertension, and the sodium content of children's diets. SUMMARY Advice to parents on feeding children should be based on the food pyramid and include information on exercise. Recent publications suggest that children consume dairy products, even if lactose intolerant, restrict juice intake, remove sweetened beverages from their diets and reduce sodium consumption.

Abstract
It has been proposed, on the basis of animal models and ecological studies, that consumption or metabolism of dairy sugar may increase the risk of ovarian cancer. Case-control and cohort studies of the association between lactose and dairy food consumption and ovarian cancer risk, however, have yielded varied findings. We summarized the available literature on this topic using a meta-analytic approach. Random-effects models were used to estimate the summary relative risks (RR(summary)). A linear regression analysis of the natural logarithm of the RR was carried out to assess a possible dose-response relationship between lactose intake and ovarian cancer risk. Eighteen case-control and 3 prospective cohort studies were eligible for inclusion in the meta-analysis. The findings of case-control studies were heterogeneous, and, except for whole milk (RR(summary) for highest vs. lowest category = 1.27, 95% confidence interval [CI] = 0.97-1.68), do not provide evidence of positive associations between dairy food and lactose intakes with risk of ovarian cancer. In contrast, the 3 cohort studies are consistent and show significant positive associations between intakes of total dairy foods, low-fat milk, and lactose and risk of ovarian cancer. The RR(summary) for a daily increase of 10 g in lactose intake (the approximate amount in 1 glass of milk) was 1.13 (95% CI = 1.05-1.22) for cohort studies. In conclusion, prospective cohort studies, but not case-control studies, support the hypothesis that high intakes of dairy foods and lactose may increase the risk of ovarian cancer.

Abstract
Lactose is a very important sugar because of its abundance in the milk of humans and domestic animals. Lactose is a valuable asset as a basic nutrient and the main substrate in fermentative processes that led to the production of fermented milk products, such as yogurt and kefir. In some instances, lactose also can be a problem as the causative agent of some diseases, such as lactose intolerance and galactosemia, or for being a by-product generated in huge amounts by the cheese industry. The study of the biochemical reactions leading to the synthesis and assimilation of lactose has provided valuable models for the understanding of biosynthetic and catabolic processes. Lactose-hydrolyzing enzymes are structurally and phylogenetically related to different types of beta-galactosidases and bacterial cellobiases involved in the enzymatic degradation of cellulose. Biotransformation of lactose, by either enzymatic or fermentative procedures, is important for different types of industrial applications in dairy and pharmaceutical industries.

Abstract
BACKGROUND Feeding intolerance (ie, achieving and maintaining full enteral feedings) is a significant problem in preterm infants. A relation exists between feeding intolerance and incomplete lactose digestion. OBJECTIVES We sought to identify the factors relating to lactose digestion and absorption, lactase activity, and small-intestinal mucosal growth. DESIGN Lactose digestion and absorption, lactase-specific activity, and lumen-to-mucosa water flux as a measure of small-intestinal mucosal surface area were determined by using the triple-lumen perfusion technique on 2 occasions 3 wk apart in 10 preterm infants (x+/-SEM gestational age: 28.0+/-0.2 wk). RESULTS Lactose digestion and absorption and lactase activity doubled between studies (P=0.035 and P=0.041, respectively). The change in digestion and absorption was related to lactase activity (P=0.034, R2=0.38). Lactase activity correlated with gestational age at birth (P=0.012, R2=0.51). The number of days of feeding explained 80% of the variability in small-intestinal mucosal surface area (P=0.001). CONCLUSIONS To our knowledge, this is the first study to measure directly lactose digestion and absorption, lactase activity, and small-intestinal surface area in preterm infants. Changes in lactose absorption relate primarily to lactase activity rather than to mucosal growth. We showed directly a relation between enteral feeding and small-intestinal mucosal growth.

Abstract
Milk from domestic cows has been a valuable food source for over 8,000 years, especially in lactose-tolerant human societies that exploit dairy breeds. We studied geographic patterns of variation in genes encoding the six most important milk proteins in 70 native European cattle breeds. We found substantial geographic coincidence between high diversity in cattle milk genes, locations of the European Neolithic cattle farming sites (>5,000 years ago) and present-day lactose tolerance in Europeans. This suggests a gene-culture coevolution between cattle and humans.

OBJECTIVE To examine daily cows milk consumption and duration of breastfeeding in infants and young children with anal fissure and constipation. METHODS Two groups of 30 consecutive children aged between 4 months and 3 years were evaluated retrospectively. Group I comprised children with chronic constipation and anal fissure in whom surgical causes were excluded, and group II comprised normal children. The daily consumption of cows milk, duration of breastfeeding and other clinical features of the children were investigated RESULTS The mean daily consumption of cows milk was significantly higher in group I (756 mL, range 200-1500 mL) than group II (253 mL, range 0-1000 mL) (P < 0.001). Group I children were breastfed for a significantly shorter period (5.8 months, range 0-18 months) than group II (10.1 months, range 2-24 months) (P < 0.006). The odds ratios for the two factors - children consuming more than 200 mL of cows milk per day (25 children in group I, 11 children in group II) and breastfeeding for less than 4 months (16 children in group I, 5 children in group II) - were calculated to be 8.6 (95% confidence interval [CI]: 0.23-0.74, P = 0.0005) and 5.7 (95% CI: 0.37-0.66, P = 0.007), respectively. CONCLUSIONS Infants and young children with chronic constipation and anal fissure may consume larger amounts of cows milk than children with a normal bowel habit. Additionally, shorter duration of breastfeeding and early bottle feeding with cows milk may play a role in the development of constipation and anal fissure in infants and young children.

Diarrhoea and gastroenteritis in the infant and young child. THE JOURNAL OF FAMILY HEALTH CARE 2003; 12:146-50. [PMID: 12630142] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 03/01/2023]
Abstract
Gastroenteritis is a major cause of diarrhoea in children. These children first present in the primary care setting for management, and the management and advice given varies between different practitioners. Unfortunately, the treatment and advice offered can occasionally be inadequate and inappropriate. This article highlights basic principles of management of gastroenteritis in children. The aim is to produce easily understandable, usable and reproducible evidence-based guidelines.

Abstract
OBJECTIVE To compare three low-lactose milk formulas differing in osmolality and degree of protein hydrolysis in the treatment of diarrhoea and malnutrition in subjects with high rates of lactose intolerance, osmotic diarrhoea and a tropical/environmental enteropathy. METHODS A randomized double-blind trial of 180 Aboriginal children under 3 years of age admitted with acute diarrhoea and/or malnutrition was carried out. The intervention milk formulas were: (i) De-Lact, a low-osmolality lactose-free formula; (ii) O-Lac, a lactose-free formula; and (iii) Alfaré, a partially hydrolysed formula. Outcome measures were diarrhoeal severity, weight gain, formula palatability and changes in intestinal permeability (L/R ratios). RESULTS The duration of diarrhoea in days (mean; 95% confidence interval) was significantly longer on Alfaré (8.5; 7.0-10.0) compared to De-Lact (6.1; 5.0-7.2) and O-Lac (6.9; 5.6-8.1; P = 0.04). There were no differences in mean intake between formulas, but palatability of Alfaré was significantly worse (P < 0.01) than the other formulas. Over the trial 5 days, improvement in L/R ratios was significantly greater (P = 0.05) for De-Lact (18.6; 10.6-26.6) than for Alfaré (8.5; 2.1-14.9). Weight gain was not significantly different between the three formulas, except in a malnourished subgroup who had better weight gain on De-Lact (P = 0.05). CONCLUSIONS In these Aboriginal children with diarrhoea and growth failure, a low osmolality milk was associated with better outcomes and a partially hydrolysed formula with less improvement in mucosal recovery, suggesting that cow's milk protein intolerance is not contributing to greater diarrhoeal severity or enteropathy in Aboriginal children.

Abstract
Irritable bowel syndrome affects 10% of adults with an unexplained female predominance. Although only a few people see their family doctor, the disease causes reduced quality of life and represents a multi-billion pound health-care problem. The disorder clusters in families, which is possibly because of intra-familial learning and a genetic predisposition. Visceral hypersensitivity is a key feature in most patients. Results of imaging studies of regional cerebral blood flow during rectal distension suggest underlying disturbances of central processing of afferent signals, though this is not unique to the disorder, since it is seen in other chronic pain syndromes. Environmental factors that are strongly implicated in at least some patients include gastrointestinal infection and inflammation and chronic stress. Diagnosis is based on positive symptoms and absence of any alarm indicators. Treatment remains unsatisfactory and hinges on an excellent doctor-patient relationship, with drugs for symptom exacerbations. Cognitive behavioural treatment, psychotherapy, and hypnosis could provide long-lasting benefit in some patients. Tricyclic antidepressants in low doses seem to be the most effective class of drugs for the disorder on the basis of limited data.
