A theory-based randomized controlled trial in promoting fruit and vegetable intake among schoolchildren: PROFRUVE study.

Purpose: The main objective of the PROFRUVE study was to evaluate the effectiveness of a TPB-based intervention program at increasing fruit and vegetable (FV) consumption in schoolchildren aged 7-10.

Methods: Eight eligible classrooms were randomly assigned to the intervention (classrooms n = 4; children n = 90) or control group (classrooms n = 4; children n = 95). The intervention group received 14 sessions of 1 h during an academic year (from October to June) but the control group did not.

Are conjugated linolenic acid isomers an alternative to conjugated linoleic acid isomers in obesity prevention?

Despite its benefits, conjugated linoleic acid (CLA) may cause side effects after long-term administration. Because of this and the controversial efficacy of CLA in humans, alternative biomolecules that may be used as functional ingredients have been studied in recent years. Thus, conjugated linolenic acid (CLNA) has been reported to be a potential anti-obesity molecule which may have additional positive effects related to obesity.

Resveratrol regulates lipolysis via adipose triglyceride lipase.

Resveratrol has been reported to increase adrenaline-induced lipolysis in 3T3-L1 adipocytes. The general aim of the present work was to gain more insight concerning the effects of trans-resveratrol on lipid mobilization. The specific purpose was to assess the involvement of the two main lipases: adipose triglyceride lipase (ATGL) and hormone-sensitive lipase (HSL), in the activation of lipolysis induced by this molecule.

Age-related changes in fatty acids from different adipose depots in rat and their association with adiposity and insulin.

Objective: We studied age-related changes in fatty acids (FAs) from serum and adipose tissue in rats by comparing different adipose regions and analyzed their relations to adiposity and insulin function.

Methods: Female weaned rats were fed on a high-fat diet until 6, 14, and 20 mo of age (n = 12, n = 6, n = 10, respectively). Body weight, adiposity, serum insulin, serum glucose, and homeostatic model assessment index were measured.

Adiponectin is involved in the protective effect of DHEA against metabolic risk in aged rats.

The aim of the present work was to analyze the effect of dehydroepiandrosterone (DHEA) on several metabolic risk factors, including cardiovascular health and insulin resistance, in aged rats submitted to a high-fat diet. For that, weaned rats were fed on a high-fat diet until 20 months of age. In the last 13 weeks of life, a group (n=11) received the diet supplemented with DHEA (0.

Responses to dietary macronutrient distribution of overweight rats under restricted feeding.

Changes in protein and amino acid balance after energy-restricted feeding have scarcely been studied, although it has been suggested that protein utilization may depend on the macronutrient composition of the restricted diet. The aim of this study is to investigate the influence of dietary fat quality and content, during an energy-restricted regime, on body composition and protein metabolism. Therefore, diet-induced overweight rats were divided into three dietary groups: one group was fed on a control diet ad libitum (control) and the other two groups were fed energy-restricted diets (about 60% of control group), which provided a standard amount (20%) of fat (SFR), based on olive oil, or a high amount (60%) of saturated fat (HFR), based on coconut oil.
