Effects of dietary fiber intake on risk factors for cardiovascular disease in subjects at high risk
2009
Background: Epidemiological studies and feeding trials with supplements suggest that fibre intake is associated with a reduction in cardiovascular risk. However, the effects of changes in dietary fibre on risk factor levels have not been evaluated in free-living individuals. Thus, the effects of changes in dietary fibre intake on cardiovascular risk factors were assessed over 3 months in free-living high-risk subjects. Methods: 772 high-risk subjects (age 69±5 years) were assigned to a low-fat diet or two Mediterranean-style diets. All participants received behavioural and nutritional education, including recommendations for increasing the consumption of vegetables, fruits, and legumes. Cha…
Diabetes-related nutrition knowledge and dietary intake among adults with type 2 diabetes.
2015
Nutrition knowledge and skills enable individuals with type 2 diabetes (T2DM) to make food choices that optimise metabolic self-management and quality of life. The present study examined the relationship between nutrition knowledge and skills, and nutrient intake in T2DM. A cross-sectional analysis of diabetes-related nutrition knowledge and nutrient intake was conducted in 124 T2DM individuals managed in usual care (64 % male, age 57·4 (sd 5·6) years, BMI 32·5 (sd 5·8) kg/m2), using the Audit of Diabetes Knowledge (ADKnowl) questionnaire and a 4 d food diary. Data on sociodemographic characteristics, food label use and weight management were also collected. The average ADKnowl dietary subs…
Total and Subtypes of Dietary Fat Intake and its Association with Components of the Metabolic Syndrome in a Mediterranean Population at High Cardiova…
2019
Background: The effect of dietary fat intake on the metabolic syndrome (MetS) and in turn on cardiovascular disease (CVD) remains unclear in individuals at high CVD risk. Objective: To assess the association between fat intake and MetS components in an adult Mediterranean population at high CVD risk. Design: Baseline assessment of nutritional adequacy in participants (n = 6560, men and women, 55&ndash
Hypothalamic reactive oxygen species are required for insulin-induced food intake inhibition: an NADPH oxidase-dependent mechanism
2009
1939-327X (Electronic) Journal Article Research Support, Non-U.S. Gov't; OBJECTIVE: Insulin plays an important role in the hypothalamic control of energy balance, especially by reducing food intake. Emerging data point to a pivotal role of reactive oxygen species (ROS) in energy homeostasis regulation, but their involvement in the anorexigenic effect of insulin is unknown. Furthermore, ROS signal derived from NADPH oxidase activation is required for physiological insulin effects in peripheral cells. In this study, we investigated the involvement of hypothalamic ROS and NADPH oxidase in the feeding behavior regulation by insulin. RESEARCH DESIGN AND METHODS: We first measured hypothalamic RO…
Does ethanol intake interfere with the evaluation of glycated hemoglobins?
1989
Ethanol and/or its metabolites interfere with the chromatographic assay of glycated hemoglobins. Fasting plasma glucose, blood ethanol, HbA(1), HbA(1c), HbA(1a+b), MCV and GGT were determined in 22 control subjects; 22 alcoholics, 22 diabetic patients and 22 alcoholic diabetic patients. Fasting plasma glucose and all hemoglobin fractions were lower in alcoholic subjects and, except for HbA(1a+b), higher in diabetic patients and in alcoholic diabetic patients. HbA(1), and HbA(1c) correlated well with plasma glucose but not with blood ethanol, MCV and GGT. Glycated hemoglobin was not found to be a useful marker for alcohol abuse. With the chromatographic method we used, the evaluation of glyc…
Time course of changes in serum oxidant/antioxidant status in overfed obese rats and their offspring.
2009
The aim of the present study was to determine the time course of changes in oxidant/antioxidant status, as well as serum glucose, insulin, leptin and lipid levels, liver adipose tissue and muscle lipid and protein contents, in cafeteria-diet-fed dams during gestation and lactation, and in their offspring throughout adulthood. Food intake was also evaluated. The cafeteria diet induced a significant increase in maternal body and relative adipose tissue weights, daily energy intake, and plasma glucose, insulin, leptin and lipid levels at parturition (day 0) and at the end of lactation (day 21). Plasma total antioxidant status [ORAC (oxygen radical absorbance capacity)], erythrocyte catalase an…
Obesity interferes with the orosensory detection of long-chain fatty acids in humans
2014
Background: The association between the orosensory detection of lipids, preference for fatty foods, and body mass index (BMI; in kg/m 2 ) is controversial in humans. Objective: We explored the oral lipid-sensing system and the orosensory-induced autonomic reflex system in lean and obese subjects. Design: Lean (BMI: 19 to ,25; n = 30) and obese (BMI .30; n = 29) age-matched men were enrolled. Their oral threshold sensitivity to linoleic acid (LA) was determined by using a 3-alternative forced-choice ascending procedure, and their eating habits were established by the analysis of 4 consecutive 24-h food-consumption diaries. The effect of brief oral lipid stimulations on plasma triglyceride [(…
Child Nutrition and Bone Health
2018
AbstractNutrition is one of the modifiable factors that contributes to bone accrual during childhood and adolescence, a critical period to prevent adult osteoporosis. Calcium and vitamin D seem to be the most important nutrients for optimal bone growth. Requirements for calcium intake are different among countries and organizations, and exact recommendations are difficult to determine since other dietary factors directly affect calcium metabolism, such as salt intake and vitamin D levels. Some scientists have suggested that the actual calcium requirements are overestimated and that increased dairy intake does not necessarily translate to better bone health in adults. Moreover, calcium can b…
Perfluoroalkyl substances in Breast milk, infant formula and baby food from Valencian Community (Spain)
2016
Environmental and human exposures to perfluoroalkyl substances (PFASs) are of emerging concern since they are persistent and bioaccumulative. The present study reports PFASs levels in human milk, infant formulas and baby food (dry cereals and pots) from the Valencian Community (Spain) in order to evaluate the infant exposure to these substances through the diet. The results show that perfluorobutanoic acid (PFBA) and perfluorooctanoic acid (PFOA) were in all the samples of the four selected matrices (except PFOA in one sample of dry cereal baby food). Perfluoroheptanoic acid (PFHpA) and perfluorodecanoic acid (PFDA) were also detected in 70% of the breast milk samples. In infant formulas, P…
Link between Intestinal CD36 Ligand Binding and Satiety Induced by a High Protein Diet in Mice
2012
International audience; CD36 is a ubiquitous membrane glycoprotein that binds long-chain fatty acids. The presence of a functional CD36 is required for the induction of satiety by a lipid load and its role as a lipid receptor driving cellular signal has recently been demonstrated. Our project aimed to further explore the role of intestinal CD36 in the regulation of food intake. Duodenal infusions of vehicle or sulfo-N-succinimidyl-oleate (SSO) was performed prior to acute infusions of saline or Intralipid (IL) in mice. Infusion of minute quantities of IL induced a decrease in food intake (FI) compared to saline. Infusion of SSO had the same effect but no additive inhibitory effect was obser…
