Adipose tissue is a vital component of the human body, but in excess, it represents a risk to health. According to the World Health Organization, one of the main factors determining excessive body adiposity is the dietary habit. This systematic review investigated longitudinal studies that assessed the association between diet and body fat in adolescents and young adults. Twenty-one relevant papers published between 2001 and 2015 were selected. The most used method for estimating body fat was the body mass index (15 studies)...

INTRODUCTION: Across the U.S., afterschool programs (ASPs, 3:00pm-6:00pm) are trying to achieve nationally endorsed nutrition standards (Healthy Eating Standards) calling for fruits/vegetables and water to be served every day, while eliminating sugar-sweetened beverages and foods. The purpose of this study was to evaluate the 2-year changes in the types of foods and beverages served during a community-based intervention designed to achieve the Healthy Eating Standards. STUDY DESIGN: Randomized delayed treatment trial with an immediate (1-year baseline and 2-year intervention) or delayed (2-year baseline and 1-year intervention) group...

D-tagatose is a prospective functional sweetener that can be produced by L-arabinose isomerase (AI) from D-galactose. To improve the activity of AI toward D-galactose, the AI of Bacillus coagulans was rationally designed based on molecular modeling and docking. After alanine scanning and site-saturation mutagenesis, variant F279I that exhibited improved activity toward D-galactose was obtained. The optimal temperature and pH of F279I were determined to be 50°C and 8.0, respectively. This variant possessed 1...

Sugar 4-epimerization reactions are important for the production of rare sugars and their derivatives, which have various potential industrial applications. For example, the production of tagatose, a functional sweetener, from fructose by sugar 4-epimerization is currently constrained because a fructose 4-epimerase does not exist in nature. We found that class II D-fructose-1,6-bisphosphate aldolase (FbaA) catalyzed the 4-epimerization of D-fructose-6-phosphate (F6P) to D-tagatose-6-phosphate (T6P) based on the prediction via structural comparisons with epimerase and molecular docking and the identification of the condensed products of C3 sugars...

Although the use of low-calorie sweeteners (LCSs) is widespread, methods of assessing consumption within free-living populations have inherent limitations. Five commonly consumed LCSs, namely, acesulfame-K, saccharin, sucralose, cyclamate, and steviol glycosides, are excreted via the urine, and therefore a urinary biomarker approach may provide more objective LCS intake data. A LC-ESI-MS/MS method of simultaneously determining acesulfame-K, saccharin, sucralose, cyclamate, and the excretory metabolite of steviol glycosides, steviol glucuronide, in human urine was developed and validated...

Food sources of nutrients in Mexican children are not well known. To fill the knowledge gap, dietary intake was assessed in 2057 children using a 24-hour dietary recall. All reported foods and beverages were assigned to one of 76 food groups. Percent contribution of each food group to nutrient intake was estimated for four age groups: 0-5.9, 6-11.9, 12-23.9, and 24-47.9 months. Breast milk, infant formula, and cow's milk were the top sources of energy and nutrients, especially in younger groups. Among infants aged 6-11...

V Lee Grotz, Xavier Pi-Sunyer, Daniel Porte, Ashley Roberts, J Richard Trout
The discovery of gut sweet taste receptors has led to speculations that non-nutritive sweeteners, including sucralose, may affect glucose control. A double-blind, parallel, randomized clinical trial, reported here and previously submitted to regulatory agencies, helps to clarify the role of sucralose in this regard. This was primarily an out-patient study, with 4-week screening, 12-week test, and 4-week follow-up phases. Normoglycemic male volunteers (47) consumed ∼333.3 mg encapsulated sucralose or placebo 3x/day at mealtimes...

BACKGROUND: Use of nonnutritive sweeteners (NNSs), which provide sweet taste with few to no calories, has increased, but data on whether children's hedonic responses to NNSs differ from nutritive sugars or from adults' hedonic responses are limited. METHODS: Most preferred levels of sucrose and the NNS sucralose were determined via a forced-choice tracking procedure in 48 children, 7-14 years (mean = 10 years), and 34 adults. Each participant also rated the liking of these taste stimuli, as well as varying concentrations of aspartame on 3- and 5-point facial hedonic scales...
