INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16060990. [PMID: 30893884 PMCID: PMC6466419 DOI: 10.3390/ijerph16060990] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/05/2019] [Revised: 03/14/2019] [Accepted: 03/15/2019] [Indexed: 11/16/2022]
Abstract
Background: To examine associations of adolescents’ weight status perception and weight control intentions with dietary intakes. Methods: Cross-sectional data from adolescents aged 10–15 in the National Health and Nutrition Examination Surveys, 2005–2014 (n = 4940). Adolescents responded to questions regarding weight perception and if they were trying to change their weight. Intakes of calories, protein, carbohydrate, fat, saturated fat, sugar, and fiber were assessed using 24-h dietary recalls. Multivariable linear regression estimated associations of intakes with weight perception and weight control intentions. Results: The majority of adolescents perceived their weight as “about right”; however, 45% and 46% of boys and girls, respectively, reported trying to change their weight. Weight perception was not associated with intakes, with the exception of lower sugar (−13.65 g, 95% CI: −23.06, −4.23) and higher percent calories from protein (1.01%, 95% CI: 0.16, 1.87) in boys with overweight/obesity who perceived themselves as overweight, as well as lower percent calories from saturated fat (−1.04%, 95% CI: −2.24, −0.17) among girls with normal weight who perceived themselves as overweight. Weight control intentions were associated with intakes in boys only. Compared to boys who never tried to lose weight, boys who tried to lose weight consumed fewer calories (−188.34 kcal, 95% CI: −357.67, −19.01), a lower percent of calories from fat (−1.41%, 95% CI: −2.80, −0.02), and a greater percent of calories from protein (1.48%, 95% CI: 0.41, 2.55). Conclusions: Despite perceiving weight as “about right”, many adolescents reported trying to change their weight, which was associated with some dietary intakes. Efforts may be necessary to educate adolescents on healthy nutrition and weight management behaviors.

Abstract
BACKGROUND AND PURPOSE Daily soda consumption may lead to high energy intake and poor diet quality. Although diet sodas contain no calories, they lack healthful nutrients. The study examined different types of soda consumption [regular (sugar-sweetened) sodas, diet sodas, and non-sodas] associated with overall diet quality. METHODS Cross sectional, 24-hour dietary recall data from the National Health and Nutrition Examination Survey (NHANES) from 2005-2012 were utilized for the study. Majority of the participants (n = 4,427) were female (57%), adults aged 19-55 years (51%), and non-Hispanic whites (67%). Nutritional Quality Index (NQI) was calculated as an indicator of diet quality. Multiple linear regression models were used to estimate the significant association between types of soda consumption and NQI stratified by body mass index. RESULTS Regular soda drinkers had lower NQI than diet soda drinkers, but only for overweight (β =-9.72; p=0.031) and obese (β =-7.06; p<0.002) individuals. Non-soda drinkers had higher NQI compared to diet soda drinkers in normal weight (β =12.38; p=0.006) and obese (β =6.19; p<0.000) individuals. CONCLUSION Nutrition intervention programs, therefore, should target overweight and obese soda drinkers, emphasizing reduction in soda consumption, which may improve nutrient density in their diets and subsequently impact long-term health outcomes.

Abstract
OBJECTIVE The objective of this study was to determine the relationship between added sugar and dietary diversity, micronutrient intakes and anthropometric status in a nationally representative study of children, 1-8.9 years of age in South Africa. METHODS Secondary analysis of a national survey of children (weighted n = 2,200; non weighted n = 2818) was undertaken. Validated 24-hour recalls of children were collected from mothers/caregivers and stratified into quartiles of percentage energy from added sugar (% EAS). A dietary diversity score (DDS) using 9 food groups, a food variety score (FVS) of individual food items, and a mean adequacy ratio (MAR) based on 11 micronutrients were calculated. The prevalence of stunting and overweight/obesity was also determined. RESULTS Added sugar intake varied from 7.5-10.3% of energy intake for rural and urban areas, respectively. Mean added sugar intake ranged from 1.0% of energy intake in Quartile 1 (1-3 years) (Q1) to 19.3% in Q4 (4-8 years). Main sources of added sugar were white sugar (60.1%), cool drinks (squash type) (10.4%) and carbonated cool drinks (6.0%). Added sugar intake, correlated positively with most micronutrient intakes, DDS, FVS, and MAR. Significant negative partial correlations, adjusted for energy intake, were found between added sugar intake and intakes of protein, fibre, thiamin, pantothenic acid, biotin, vitamin E, calcium (1-3 years), phosphorus, iron (4-8 years), magnesium and zinc. The prevalence of overweight/obesity was higher in children aged 4-8 years in Q4 of %EAS than in other quartiles [mean (95%CI) % prevalence overweight 23.0 (16.2-29.8)% in Q4 compared to 13.0 (8.7-17.3)% in Q1, p = 0.0063]. CONCLUSION Although DDS, FVS, MAR and micronutrient intakes were positively correlated with added sugar intakes, overall negative associations between micronutrients and added sugar intakes, adjusted for dietary energy, indicate micronutrient dilution. Overweight/obesity was increased with higher added sugar intakes in the 4-8 year old children.

Abstract
CONTEXT Given its potential effect on nutrient and energy density, the sugar content of the diet is a subject of controversy. OBJECTIVE The aim of this review was to examine the cross-sectional or prospective evidence for associations between the intake of total sugar or added sugar (high vs low intakes) and diet quality or nutrient intakes in the general population. DATA SOURCES The following databases were searched for English-language articles published between 1972 and 2012: CINAHL Plus, EBM Reviews, ERIC, MEDLINE, PREMEDLINE, PsycINFO, PubMed, and ScienceDirect. STUDY SELECTION The search identified studies that examined the association between intake of total sugar and/or added sugar and diet quality (n = 22) or nutrient intakes (n = 30). DATA EXTRACTION The following data were extracted: sample size and population, dietary assessment method, source of added sugar data, source of funding, comparator, association between total sugar or added sugar and diet quality, and the direction and magnitude of the association. DATA SYNTHESIS Of 22 studies, all except 1 found a higher intake of added sugar to be associated with poorer diet quality, and the exceptional study did not adjust for total energy intake. Twenty-one of 30 studies found a negative association between added sugar and micronutrient intakes. The same association was not found for total sugar intake. CONCLUSION Any negative association between dietary sugar and diet quality is better exposed by referring to added sugar rather than total sugar. There was substantial variation in features of study quality, including sample size, so the magnitude of the observed effect was generally small and may not be of clinical significance. Furthermore, the positive influence that core foods such as fruit and milk exert on total sugar values may bias the association between total sugar and diet quality.

Abstract
Further to reports of a reciprocal relationship between sugar and fat intakes, this review aimed to provide an in-depth analysis and to determine the likely influence of this relationship on the achievement of population dietary guidelines. Using systematic methods, relevant literature was selected according to preset criteria. A strong and consistent inverse association was found between total sugars and total fat intakes expressed as percentage energy. Fewer studies considered absolute intakes and these reported a positive relationship, which may be influenced by confounding with energy intakes. Evidence for an inverse relationship between percentage energy from fat and extrinsic sugars was weaker and less consistent than for fat and total sugars. Reciprocal relationships were also observed for sugar-saturated fat, sugar-protein, sugar-alcohol, and sugar-starch expressed as percentage energy. Under-reporting of dietary intakes had no major influence on the findings. This review confirms the existence of the sugar-fat seesaw on a percentage energy basis and concludes that it is most likely explained by a combination of mathematical and food compositional effects. This finding is relevant because dietary guidelines are expressed as percentage energy and implies that at the population level multiple guidelines may be difficult to achieve in practice.

Abstract
Several different vitamins and minerals appear to be effective augmenting agents for mood-modifying drugs, but are not potent monotherapies in themselves for treating psychiatric disorders. In contrast, broad-spectrum micronutrient interventions appear in early trials to be as effective as psychiatric medications with fewer adverse effects for treating mood disorders, ADHD, aggressivity, and misconduct in youth and adults. Broad-spectrum treatments also may improve stress responses, cognition, and sense of well-being in healthy adults, but have been less well studied in youth. Current clinical data justify an extensive expansion of research on micronutrient mechanisms and treatments in psychiatry.

Abstract
The present study aimed to evaluate the association between the consumption of energy-dense foods at 2 years of age and the consumption of foods and diet quality at 4 years of age. The sample included 705 children evaluated at 2 and 4 years of age, as part of the population-based birth cohort Generation XXI (Porto, Portugal). Data on sociodemographic and lifestyle factors of both children and mothers were collected by face-to-face interviews. The weight and height of children were measured by trained professionals. Based on FFQ, four energy-dense food groups were defined: soft drinks; sweets; cakes; salty snacks. A healthy eating index was developed using the WHO dietary recommendations for children (2006) aged 4 years. The associations were evaluated through Poisson regression models. After adjustment for maternal age and education, child's carer, child's siblings and child's BMI, higher consumption of energy-dense foods at 2 years of age was found to be associated with higher consumption of the same foods 2 years later. An inverse association was found between the intake ( ≥ median) of soft drinks (incidence rate ratio (IRR) = 0·74, 95 % CI 0·58, 0·95), salty snacks (IRR = 0·80, 95 % CI 0·65, 1·00) and sweets (IRR = 0·73, 95 % CI 0·58, 0·91) at 2 years of age and the consumption of fruit and vegetables at 4 years of age ( ≥ 5 times/d). Weekly and daily consumption of energy-dense foods at 2 years of age was associated with a lower healthy eating score at 4 years of age (IRR = 0·75, 95 % CI 0·58, 0·96; IRR = 0·56, 95 % CI 0·41, 0·77, respectively). The consumption of energy-dense foods at young ages is negatively associated with the diet quality of children a few years later.

Abstract
OBJECTIVE To describe the regional and socio-economic distribution of consumption of added sugar in Brazil in 2002/03, particularly products, sources of sugar and trends in the past 15 years. METHODS The study used data from Household Budget Surveys since the 1980s about the type and quantity of food and beverages bought by Brazilian families. Different indicators were analyzed: % of sugar calories over the total diet energy and caloric % of table sugar fractions and sugar added to processed food/ sugar calories of diet. RESULTS In 2002/03, of the total energy available for consumption, 16.7% came from added sugar in all regional and socio-economic strata. The table sugar/ sugar added to processed food ratio was inversely proportional to increase in income. Although this proportion fell in the past 15 years, sugar added to processed food doubled, especially in terms of consumption of soft drinks and cookies. CONCLUSIONS Brazilians consume more sugar than the recommended levels determined by the WHO and the sources of consumption of sugar have changed significantly.

Abstract
This study compared nutrient intake and body weight measures in children 4 to 8 (n = 1480) and 9 to 13 (n = 1790), and adolescents 14 to 18 years of age (n = 1826) participating in 1999-2002 NHANES and consuming a presweetened ready-to-eat cereal (PSRTEC), a non-PSRTEC (NPSRTEC), or other breakfast (OB). Sample weights were applied, and logistic regression identified differences among breakfast consumption groups controlling for appropriate covariates. Breakfast type varied by the above-mentioned age groups: 34% (n = 507), 33% (n = 593), and 23% (n = 416) consumed PSRTEC, respectively; 12% (n = 178), 9% (n = 165), and 8% (n = 144), respectively, consumed NPSRTEC; and 54% (n = 795), 58% (n = 1032), and 69% (n = 1266), respectively, consumed OBs. RTEC consumers had significantly higher intakes of thiamin, riboflavin, niacin, vitamin B6 and B12, folate, calcium, magnesium, iron, and zinc than OB consumers. In children 4 to 8 years old and 9 to 13 years old, added sugars (103.3 ± 2.6 and 111.3 ± 3.0 g) were highest in PSRTEC consumers. Fiber intake was highest in NPSRTEC (4-8 and 9-13 years of age) consumers (14.3 ± 0.4 and 14.7 ± 0.7 g) and lowest in 14- to 18-year-old OB consumers (11.9 ± 0.3 g). Weight measures were not higher in either group of RTEC consumers compared with OB consumers. Data suggest that RTEC contribute a high level of nutrients to the diet, and PSRTEC is not associated with higher body weight in children.

Abstract
Many countries set quantitative targets for added sugars, justifying this by expressing concern about the likely impact of sugar on weight control, dental health, diet quality, or metabolic syndrome. This review considers whether current intakes of sugar are harmful to health, and analyses recent literature using a systematic approach to collate, rank, and evaluate published studies from 1995-2006. Results from high quality obesity studies did not suggest a positive association between body mass index and sugar intake. Some studies, specifically on sweetened beverages, highlighted a potential concern in relation to obesity risk, although these were limited by important methodological issues. Diet adequacy appeared to be achieved across sugar intakes of 6 to 20% energy, depending on subject age. Studies on metabolic syndrome reported no adverse effects of sugar in the long-term, even at intakes of 40-50% energy. The evidence for colorectal cancer suggested an association with sugar, but this appeared to have been confounded by energy intake and glycemic load. There was no credible evidence linking sugar with attention-deficit, dementia, or depression. Regarding dental caries, combinations of sugar amount/frequency, fluoride exposure, and food adhesiveness were more reliable predictors of caries risk than the amount of sugar alone. Overall, the available evidence did not support a single quantitative sugar guideline covering all health issues.

Abstract
Avaliou-se a influência exercida pela aquisição de calorias de açúcar sobre a participação calórica dos demais macronutrientes da dieta. As estimativas deste estudo são baseadas em dados da Pesquisa de Orçamentos Familiares realizada no Brasil pelo Instituto Brasileiro de Geografia e Estatística entre julho de 2002 e junho de 2003. Modelos de regressão linear múltiplos foram utilizados para estudar a influência das calorias de açúcar sobre a participação calórica de cada um dos macronutrientes na aquisição domiciliar de alimentos com o controle do valor calórico total da aquisição de alimentos e variáveis sócio-demográficas. Cada caloria adquirida de açúcar eleva em 0,3 caloria a participação de gorduras na aquisição domiciliar de alimentos e diminui em 0,07 a participação de proteínas. Cada caloria de açúcar procedente de alimentos processados aumenta em 1,6 caloria a participação de gorduras e em 0,4 caloria de ácidos graxos saturados e diminui em 0,8 caloria a participação de outros carboidratos que não o açúcar. Os resultados encontrados trazem novas evidências sobre o papel prejudicial do açúcar à saúde humana.

Abstract
While virtually absent in our diet a few hundred years ago, fructose has now become a major constituent of our modern diet. Our main sources of fructose are sucrose from beet or cane, high fructose corn syrup, fruits, and honey. Fructose has the same chemical formula as glucose (C(6)H(12)O(6)), but its metabolism differs markedly from that of glucose due to its almost complete hepatic extraction and rapid hepatic conversion into glucose, glycogen, lactate, and fat. Fructose was initially thought to be advisable for patients with diabetes due to its low glycemic index. However, chronically high consumption of fructose in rodents leads to hepatic and extrahepatic insulin resistance, obesity, type 2 diabetes mellitus, and high blood pressure. The evidence is less compelling in humans, but high fructose intake has indeed been shown to cause dyslipidemia and to impair hepatic insulin sensitivity. Hepatic de novo lipogenesis and lipotoxicity, oxidative stress, and hyperuricemia have all been proposed as mechanisms responsible for these adverse metabolic effects of fructose. Although there is compelling evidence that very high fructose intake can have deleterious metabolic effects in humans as in rodents, the role of fructose in the development of the current epidemic of metabolic disorders remains controversial. Epidemiological studies show growing evidence that consumption of sweetened beverages (containing either sucrose or a mixture of glucose and fructose) is associated with a high energy intake, increased body weight, and the occurrence of metabolic and cardiovascular disorders. There is, however, no unequivocal evidence that fructose intake at moderate doses is directly related with adverse metabolic effects. There has also been much concern that consumption of free fructose, as provided in high fructose corn syrup, may cause more adverse effects than consumption of fructose consumed with sucrose. There is, however, no direct evidence for more serious metabolic consequences of high fructose corn syrup versus sucrose consumption.

Abstract
AbstractObjectiveTo study the role of energy derived from sugar (both table sugar and sugar added to processed foods) in the total energy content of food purchases in Brazil.DesignFood purchase data were collected during a national household budget survey carried out between June 2002 and July 2003 on a probabilistic sample representative of all households in the country. The amount of food purchased in this 12-month period was transformed into energy and energy from sugar using food composition tables. Multiple linear regression models were used to study the association between amount of energy from sugar and total energy content of food purchases, controlling for sociodemographic variables and potential interactions between these variables and sugar purchases.ResultsThere was a positive and significant association between energy from sugar and total household energy purchases. A 1 kJ increase in sugar purchase corresponded to a 3·637 kJ increase in total energy. In the absence of expenditure on meals outside the home, i.e. when household food purchases tend to approximate actual food consumption by household members, sugar purchase of 1926·35 kJ/d (the 90th percentile of the distribution of sugar purchases in Brazil) was associated, depending on income strata, with total energy purchase over 40–60 % of the recommended daily value for energy intake in Brazil.ConclusionsThe present results corroborate the recommendations of the WHO and the Brazilian Ministry of Health regarding limiting the consumption of sugar.

Abstract
In the present study the relationship of sugar-sweetened beverage (SSB) consumption with the intake of single nutrients and total diet quality in German children and adolescents was evaluated using a repeated-measures regression analysis model. We used dietary data from 7145 three-day weighed records of 1069 subjects aged 2-19 years participating in the Dortmund Nutritional and Anthropometric Longitudinally Designed (DONALD) Study. Intake of macronutrients as percentage of total energy intake (%En), intake of micronutrients as percentage of German reference values (intake quality score) and nutritional quality index (NQI) as an indicator of diet quality were chosen as separate dependent variables. SSB consumption was positively associated with %En from carbohydrates (boys v. girls: +4.00 v. +4.09 En%/MJ from SSB) and added sugars (boys v. girls: +7.36 v. +9.52 En%/MJ from SSB) and negatively with %En from protein (boys v. girls: - 1.25 v. - 1.31 En%/MJ from SSB) and fat (boys: - 2.82 v. - 2.73 En%/MJ from SSB). With respect to micronutrients, SSB consumption was negatively associated with folate and Ca intake, for which mean intake levels were inadequate in girls. Absolute diet quality was negatively associated with SSB consumption, whereas the effect was larger for girls (boys v. girls: - 1.41 v. - 2.63 points of NQI/MJ from SSB). Overall, results show a diluting effect of SSB consumption on micronutrient intake and diet quality. This effect might be relevant especially in girls as the association with diet quality was larger and mean NQI levels were lower in comparison with boys.

Abstract
BACKGROUND Soft drinks are thought to displace milk in diets of children and adolescents and therefore might affect variables of bone modeling and remodeling. OBJECTIVE We assessed the association between long-term consumption of several types of soft drinks and bone variables in children and adolescents. DESIGN Long-term dietary data from 3-d weighed dietary records collected by 228 healthy children and adolescents enrolled in the DONALD Study in 4 y of study participation were used for data analysis. Variables of bone modeling and remodeling of the radius were assessed by using peripheral quantitative computed tomography. RESULTS After adjustment for age, sex, total energy intake, muscle area, BMI SD scores, and growth velocity, long-term consumption of all soft drinks and uncaffeinated soft drinks was negatively associated with bone mineral content (P < 0.05), cortical area (P < 0.05), and polar strength strain index (P < 0.05), all of which reflect a combination of bone modeling and remodeling. Long-term consumption of caffeinated soft drinks was negatively associated with polar strength strain index (P < 0.01) and periosteal circumference (P < 0.05), which reflect bone modeling. Milk intake was positively associated with polar strength strain index (P < 0.05). Consumption of all soft drinks was negatively associated with total protein and milk intake, but was not associated with potential renal acid load. CONCLUSIONS Long-term consumption of caffeinated and uncaffeinated soft drinks appears to have bone catabolic effects in boys and girls. This effect is mainly mediated by the negative association with total protein intake and is not primarily based on milk displacement.

Abstract
The aim was to identify the important sources of added sucrose and determinants of high intake, and to evaluate what impact a high proportion of energy from added sucrose has on the intake of foods and nutrients. The subjects consisted of children invited to the nutrition study within the Type 1 Diabetes Prediction and Prevention birth cohort and born in 2001 (n 846). Of these, 471 returned 3 d food records at 3 years of age. The average daily intake of added sucrose was 35 (sd 17) g (11·3 % of energy intake) and that of total sucrose was 41 (sd 18) g (13·3 % of energy intake). Sucrose added by manufacturers accounted for 82 %, naturally occurring sucrose for 15 % and sucrose added by consumers for 3 % of the total sucrose. Juice drinks, yoghurt/cultured milks, and chocolate and confectionery were the main contributors to added sucrose intake. Consumption of rye bread, porridge, fresh vegetables, cooked potatoes, skimmed milk, hard cheeses, margarine and fat spread as well as intake of most nutrients decreased across the quartiles of added sucrose (P < 0·05). Being cared for at home, having a father with a vocational school degree, having at least two siblings and a milk-restricted diet increased the risk for a high-sucrose diet. The study implied that a high proportion of added sucrose in the diet had mainly an unfavourable impact on the intake of recommended foods and key nutrients in Finnish children. The rationale for the recommendation to reduce the intake of refined sugars to ensure adequate intakes of nutrients seems reasonable.

Abstract
BACKGROUND Previous studies have suggested that interventions to lower dietary fat content and improved fat quality lead to a compensatory increase in sucrose content. OBJECTIVE The purpose of this work was to determine what associations exist between sucrose intake and intake of nutrients, intake of specific foods, and growth in children aged 13 months to 9 years of age in the prospective, randomized Special Turku Coronary Risk Factor Intervention Project. SUBJECTS AND METHODS Nutrient intake and food consumption were evaluated annually at ages 13 months through 9 years by using food records. Altogether, 543 children were divided into 3 groups according to mean sucrose intake: constantly high sucrose intake (highest 10%), constantly low sucrose intake (lowest 10%), and average sucrose intake (80%). Absolute and relative weights and heights were recorded at 7, 13, and 24 months of age and annually thereafter until 9 years old. RESULTS The high sucrose-intake group exceeded the recommended sucrose intake (<10% of energy intake, World Health Organization) already at the age of 2 years. Energy and total fat intake did not differ between the sucrose-intake groups. Children with low and average sucrose intake consumed more protein and had a better dietary fat quality than children with high sucrose intake. They also tended to receive more vitamin E, niacin, calcium, iron, zinc, and dietary fiber than children who consumed a high sucrose diet. Children in the low sucrose-intake group consumed more grains, vegetables, and dairy products than the other children. Sugar intake had no direct association with obesity, but weight, height, and BMI of children differed between the sucrose-intake groups between 7 months and 9 years of age. CONCLUSIONS In children aged 13 months to 9 years, long-term low sucrose intake is associated with better nutrient intake and growth than high sucrose intake.

Relationship between energy from added sugars and frequency of added sugars intake in Irish children, teenagers and adults. Br J Nutr 2008; 99:1117-26.

Abstract
A WHO report on diet, nutrition and the prevention of chronic diseases recommended that frequency of consumption of foods and/or drinks containing free sugars should be limited to a maximum of four times per d. In addition, they recommended a reduction in the intake of free sugars to a maximum of no more than 10 % of energy intake. These recommendations were developed with the aim of reducing the prevalence of dental caries. The aim of the present study was to establish if there is a quantitative relationship between energy from added sugars and frequency of added sugars intakes in Irish children, teenagers and adults. In addition, the intake of added and total sugars and main contributors to added sugar intakes were examined. Data for the present analysis were based on the North/South Ireland Food Consumption Survey (n1379; aged 18–64 years), the National Children's Food Survey (n594; aged 5–12 years) and the National Teen Food Survey (n441; aged 13–17 years) which used 7 d food diaries to collect food and beverage intake data in representative samples of Irish adults, children and teenagers respectively. Results showed that in adults, frequency of intake of added sugar intake of four times per d corresponded to a mean added sugar intake of 9 %, which was similar to the WHO recommendation. In children and teenagers, a frequency of intake of four times per d corresponded to a mean added sugar intake of 14·6 and 12·4 % respectively and was therefore not in agreement with the WHO recommendation.

Abstract
Guidelines for sugars intake range from a population mean of less than 10 % energy from free sugars, to a maximum for individuals of 25 % energy from added sugars. The aim of the present review was to examine the evidence for micronutrient dilution by sugars and evaluate its nutritional significance. From a web-based search of MEDLINE and hand search of linked papers, forty-eight relevant publications were identified on sugars (total sugars, non-milk extrinsic sugars, or added sugars) or sugar-containing drinks. These included five reports from expert committees, six reviews, thirty-three observational studies and four small-scale interventions. There was inconsistency between studies as to the relationship between sugars intake (however expressed) and micronutrients. The statistical patterns varied between nutrients and population groups. Curvilinear associations were found in some analyses, with lower nutrient intakes at both extremes of sugar intake; however, factors such as dieting and under-reporting may confound the associations observed. Some studies found statistically significant inverse associations but these were weak, with sugars explaining less than 5 % of the variance. Mean intakes of most micronutrients were above the RDA or reference nutrient intake except among very high consumers of sugars. The available evidence does not allow for firm conclusions on an optimal level of added sugars intake for micronutrient adequacy and the trends that exist may have little biological significance except for a few nutrients (for example, Fe). It is established that energy intake is the prime predictor of micronutrient adequacy. A better understanding of valid approaches to energy adjustment, misreporting and the assessment of micronutrient adequacy is crucial to further progress in this area.

Abstract
A low fat, high carbohydrate diet in combination with regular exercise is the traditional recommendation for treating diabetes. Compliance with these lifestyle modifications is less than satisfactory, however, and a high carbohydrate diet raises postprandial plasma glucose and insulin secretion, thereby increasing risk of CVD, hypertension, dyslipidemia, obesity and diabetes. Moreover, the current epidemic of diabetes and obesity has been, over the past three decades, accompanied by a significant decrease in fat consumption and an increase in carbohydrate consumption. This apparent failure of the traditional diet, from a public health point of view, indicates that alternative dietary approaches are needed. Because carbohydrate is the major secretagogue of insulin, some form of carbohydrate restriction is a prima facie candidate for dietary control of diabetes. Evidence from various randomized controlled trials in recent years has convinced us that such diets are safe and effective, at least in short-term. These data show low carbohydrate diets to be comparable or better than traditional low fat high carbohydrate diets for weight reduction, improvement in the dyslipidemia of diabetes and metabolic syndrome as well as control of blood pressure, postprandial glycemia and insulin secretion. Furthermore, the ability of low carbohydrate diets to reduce triglycerides and to increase HDL is of particular importance. Resistance to such strategies has been due, in part, to equating it with the popular Atkins diet. However, there are many variations and room for individual physician planning. Some form of low carbohydrate diet, in combination with exercise, is a viable option for patients with diabetes. However, the extreme reduction of carbohydrate of popular diets (<30 g/day) cannot be recommended for a diabetic population at this time without further study. On the other hand, the dire objections continually raised in the literature appear to have very little scientific basis. Whereas it is traditional to say that more work needs to be done, the same is true of the assumed standard low fat diets which have an ambiguous record at best. We see current trends in the national dietary recommendations as a positive sign and an appropriate move in the right direction.

Abstract
OBJECTIVES To assess the effect of Dietary Reference Intakes (DRI)-recommended added sugar intake levels on nutrient and food group consumption by preschoolers. STUDY DESIGN This was a cross-sectional study of 2- to 5-year-olds in the United States Department of Agriculture Continuing Survey of Food Intake by Individuals (CSFII), 1994 to 1996, and 1998 (n = 5437). Main food sources of added sugar were established. For five categories (< or =10% energy from added sugar, 11% to 15%, 16% to 20%, 21% to 25%, and >25%), mean nutrient and food group consumption and proportion of children not meeting the DRI were ascertained. The nonparametric test for trend indicated significance of changes. Analysis was stratified by age (2- to 3-year-olds versus 4- to 5-year-olds), and survey design corrected to maintain the nationally representative character of the data. RESULTS The majority of children consumed less than 25% of energy from added sugar; the main sources were fruit and or soft drinks and desserts. Increasing added sugar consumption was paralleled by decreasing nutrient and food group intakes and increasing proportions of children with intakes below the DRI. Calcium intake was insufficient in large proportions of children consuming 16% or more from added sugar. CONCLUSIONS In preschoolers, the new DRI for added sugar are reason for concern. Further research is needed to investigate the effects of the DRI on diet quality, body weight, and health status in young children.

Abstract
OBJECTIVE It is debated whether the intake of added sugar displaces micronutrient-rich foods and dilutes the nutrient density of the diet, and whether there is a link between sugar and the increased rate of obesity. The objectives of this study were to examine the effect of added sugar on the intakes of energy, micronutrients, fruit and vegetables, and to examine the association between intake of added sugar and age, sex, body mass index, physical activity, inactivity and parents' education. DESIGN Participants recorded their food intake in pre-coded food diaries for 4 days and filled in a questionnaire about physical activity, watching television (TV)/using a personal computer (PC) and parents' education. SUBJECTS Three hundred and ninety-one 4-year-olds, 810 students in the 4th grade (9 years old) and 1005 in the 8th grade (13 years old) were included in the study. RESULTS The intakes of all nutrients, except alpha-tocopherol among 4-year-olds and vitamin C among 4-year-olds and 4th graders, decreased with increasing content of added sugar in the diet. Moreover, high consumers of added sugar had a 30-40% lower intake of fruit and vegetables than did low consumers. A negative association was observed between consumption of added sugar and body mass index among girls in the 8th grade (P=0.013), whereas a positive association was observed among 4-year-old boys (P=0.055). Associations between physical activity, hours spent watching TV/using a PC, parents' education and the energy intake from added sugar varied in the different age groups. CONCLUSIONS This study showed a negative association between the intake of added sugar and intakes of micronutrients, fruit and vegetables. The negative association between sugar intake and intake of fruit and vegetables is important from a public health perspective, since one of the main health messages today is to increase current intake of fruit and vegetables.

Abstract
The aim of the present analysis was to evaluate the effect of intake of added sugars on intakes of nutrients and food groups. We used a mixed linear model (PROC MIXED) to analyse data from the Dortmund Nutritional and Anthropometric Longitudinally Designed (DONALD) study (an ongoing longitudinal cohort study between infancy and adulthood). Between July 1985 and August 2001, 3 d weighed dietary records (n 4993) from 849 children and adolescents (416 male, 433 female) aged 2-18 years were collected and evaluated. Overall mean intake of added sugars was 12.4 (SD 5.3) (median 12.0) % energy. Fat intake (% energy) and intake of all analysed nutrients (as % reference values for nutrient intakes) fell across quintiles 1-5 of energy intake from added sugars (P<0.001). With the exception of 'Sugary foods' and 'Beverages' (significant increase, P<0.0001) and 'Dairy' (NS), intake of all other food groups decreased with increasing intake of added sugars (P<0.0001). In conclusion, we found a slight, but statistically significant, nutrient-dilution effect of added sugars and a significant reduction in intake of important nutrient-bearing food groups. However, the DONALD study gives no clear indicator on grounds of micronutrient dilution for a quantitative limit on intake of added sugars.

Abstract
PURPOSE To determine the long-term effects of a low fat intervention on sugar content in school lunches METHODS We calculated contributions of total sugars, 6 specific sugars, and selected nutrients in National School Lunch Program meals served in 56 former intervention, 20 randomly selected control schools that had participated 3 years before in a low fat intervention, and 12 additional schools from neighboring school districts that had never been exposed to the intervention, whose goal was the lowering of total fat to under 30% of calories and saturated fat to under 10% calories. Analysis of variance adjusted for region was used to compare treatment groups. Pearson partial correlations controlling for the effects of region and treatment group were used to assess the strength of sugar and fat relationships. RESULTS Three years after the low fat intervention, former intervention, control and unexposed schools lunches were similar in mean total sugars (25% of calories), and "added" sugars (e.g. sucrose, glucose, galactose, and maltose) at 15% of calories; and differed only in their lactose content. As percent of calories from fat or saturated fat in lunches decreased, that from sugars increased. Lunches that met reduced saturated fat goals were significantly higher than those not meeting goals in percent of calories from sugars both in meals as offered (27.6 +/- 0.3% vs. 26.2 +/- 0.3 SE p =.004) and as served (26.5 +/- 0.4 vs. 23.9 +/- 0.4 p =.009). Lunches meeting reduced total fat goals were significantly higher only in percent of calories from sugars as served. Seventy-five percent of total sugar in lunches offered was from chocolate milk, fruit/fruit juices, and white milk. More "added" sugar came from high micronutrient foods, such as fruit, fruit juices, and chocolate milk than from desserts and entrees. CONCLUSIONS The existence of a fat-sugar "see-saw" makes it important to emphasize substitutions of fat and saturated fat with starches and fiber in school lunches.

Abstract
This review explores whether fructose consumption might be a contributing factor to the development of obesity and the accompanying metabolic abnormalities observed in the insulin resistance syndrome. The per capita disappearance data for fructose from the combined consumption of sucrose and high-fructose corn syrup have increased by 26%, from 64 g/d in 1970 to 81 g/d in 1997. Both plasma insulin and leptin act in the central nervous system in the long-term regulation of energy homeostasis. Because fructose does not stimulate insulin secretion from pancreatic beta cells, the consumption of foods and beverages containing fructose produces smaller postprandial insulin excursions than does consumption of glucose-containing carbohydrate. Because leptin production is regulated by insulin responses to meals, fructose consumption also reduces circulating leptin concentrations. The combined effects of lowered circulating leptin and insulin in individuals who consume diets that are high in dietary fructose could therefore increase the likelihood of weight gain and its associated metabolic sequelae. In addition, fructose, compared with glucose, is preferentially metabolized to lipid in the liver. Fructose consumption induces insulin resistance, impaired glucose tolerance, hyperinsulinemia, hypertriacylglycerolemia, and hypertension in animal models. The data in humans are less clear. Although there are existing data on the metabolic and endocrine effects of dietary fructose that suggest that increased consumption of fructose may be detrimental in terms of body weight and adiposity and the metabolic indexes associated with the insulin resistance syndrome, much more research is needed to fully understand the metabolic effect of dietary fructose in humans.

Abstract
OBJECTIVES To determine sociodemographic predictors of added sugar intake from a national representative sample of 2- to 5-year-old children. STUDY DESIGN Cross-sectional study that used dietary intake data of the US Department of Agriculture Continuing Survey of Food Intake in Individuals 1994 to 1996 and 1998 (n = 5652). Amount of added sugar intake in teaspoons per day, teaspoons per 100 kcal, and percent of total energy was calculated by selected sociodemographic variables, accounting for sample design and weighted to permit inferences applicable to the total population. Multivariate linear regression analysis was used to predict added sugar intake. RESULTS Average added sugar consumption was 15.4 tsp/d (15.7% of total energy). Significant differences were observed by several socio-demographic characteristics. Multivariate models predicting energy-adjusted intake indicated strong associations with age, ethnicity, income, day care/school attendance, Supplemental Program for Women, Infants, and Children (WIC) participation, region of residence, and female head of household's educational level. CONCLUSIONS The identified sociodemographic predictors of high added sugar intake might help target public health messages to improve children's diet quality and prevent future chronic diseases to population groups at highest risk.

Abstract
A correlation study was designed to test the hypothesis that maternal education, perceived family resources, and the importance of family routines would be related to children's dietary patterns. Additionally, the study examined the hypothesis that dietary patterns would be associated with children's cognitive and physical abilities. The sample for this study included 159 African American single-mother families with a 6- to 9-year-old child living in rural areas, most of whom lived in poverty. Children's eating patterns were assessed using a self-report questionnaire administered to the mother in an interview format. Children's cognitive ability was measured by several subscales from the Woodcock Johnson Psycho-Educational Instrument and the Harter Perceived Competence Scale for children. For male children, the mother's higher education was related to more adequate eating patterns at home, and more perceived family resources were related to the likelihood of taking vitamin supplements. For female children, greater milk intake was positively related to cognitive outcomes, including applied problem, passage comprehension, calculation, synonym identification, antonym identification, and quantitative concept scores. Milk intake was clearly related to more optimal cognitive development. The results of this study support the literature related to the importance of nutrition for cognitive and physical abilities in children.

Abstract
OBJECTIVE The associations between added sugars intake and consumption of vitamins, minerals and servings of foods in the USDA Food Guide Pyramid were examined. METHODS Data from the USDA 1994-96 Continuing Survey of Food Intakes by Individuals were used in multivariate regression analyses to assess the statistical and practical significance of added sugars intake for diet and nutrient adequacy. RESULTS The association of added sugars with consumption of vitamins, minerals and servings of foods in the USDA Food Guide Pyramid was usually statistically significant. For the model of all individuals over two years of age, individuals who consume more added sugars are predicted to consume more grains, lean meat and iron and to consume fewer vegetables and fruits and less dairy, vitamin A, calcium and folates. Children who consume more added sugars are predicted to consume more grains, vitamin C, iron and folates and to consume less dairy. Adolescents who consume more added sugars are predicted to consume more grains, vitamin C and iron and less fruit. CONCLUSION The associations, whether positive or negative, however, were always small from either a practical perspective or in comparison to the associations of other sources of energy.
