Common Neural Mechanisms of Palatable Food Intake and Drug Abuse: Knowledge Obtained with Animal Models
2019
Eating is necessary for survival, but it is also one of the great pleasures enjoyed by human beings. Research to date shows that palatable food can be rewarding in a similar way to drugs of abuse, indicating considerable comorbidity between eating disorders and substance-use disorders. Analysis of the common characteristics of both types of disorder has led to a new wave of studies proposing a Gateway Theory of food as a vulnerability factor that modulates the development of drug addiction. The homeostatic and hedonic mechanisms of feeding overlap with some of the mechanisms implicated in drug abuse and their interaction plays a crucial role in the development of drug addiction. Studies in…
P-77D-PENICILLAMINE, A POTENTIAL ETHANOL ANTI-RELAPSE DRUG, DOES NOT REDUCE THE VOLUNTARY ETHANOL INTAKE IN LONG-TERM EXPERIENCED RATS
2015
Experimental evidence has demonstrated that the reinforcing effects of ethanol crucially depend on the brain formation of acetaldehyde (ACD). Rationally supported by this basis, we previously evaluated a novel strategy to prevent relapse in alcoholism based on chemical ACD inactivation using D-Penicillamine (DP). Under our experimental …
Pharmacology of Acamprosate: An Overview
2003
In the last years important advances have been made in the development of drugs for the treatment of alcohol addiction. Acamprosate (calcium bis‐acetylhomotaurine) is one of the better established drugs in this field on the European market. This review focuses first on the pharmacokinetics of acamprosate. The published data and the recent advances in our knowledge on the mechanisms involved in the intestinal absorption and elimination of this drug are summarized. The importance of pharmacokinetics for the proper clinical use of acamprosate is highlighted. The anti‐relapse as well as the well‐known effects of acamprosate on ethanol intake are discussed. The recent experiments in animal model…
Prediction of type 2 diabetes mellitus based on nutrition data
2021
Abstract Numerous predictive models for the risk of type 2 diabetes mellitus (T2DM) exist, but a minority of them has implemented nutrition data so far, even though the significant effect of nutrition on the pathogenesis, prevention and management of T2DM has been established. Thus, in the present study, we aimed to build a predictive model for the risk of T2DM that incorporates nutrition data and calculates its predictive performance. We analysed cross-sectional data from 1591 individuals from the population-based Cooperative Health Research in the Region of Augsburg (KORA) FF4 study (2013–14) and used a bootstrap enhanced elastic net penalised multivariate regression method in order to bu…
Dietary Sugar and Fat Exposure : Determinants and Links with Sweet Taste Liking and Fat Sensation Liking
2017
Context : Dietary exposures in the first year of life could play a role in the development of food preferences in children. Aims : To characterize dietary sweet and fat exposures in infancy and to study their links with sweet taste and fat sensation liking in school-aged children. Methods : During the first year, dietary sweet and fat exposures were assessed with a nutritional approach in the EDEN study and with a sensory approach in the OPALINE study. Next, early factors related to these dietary sweet and fat exposures were analyzed. Associations between the nutritional sweet and fat exposure and sweet taste and fat sensation liking scores in 9-to-12 y old children in the EDEN study were s…
Conséquences des variations de teneur en sel, sucre, et matière grasse sur les préférences et les consommations alimentaires des enfants
2011
Background: In France, the National Nutrition and Health Programme (“Programme National Nutrition Santé” or “PNNS”) is in charge of implementing the recommendations aiming at reducing salt, sugar and fat quantities in foods. However, the extent to which this might impact children’s food preferences and intake is limited. Objective: The present work aimed at understanding the impact of varying salt, sugar and fat variations in foods, on toddlers and children’s food preferences and intake. Methods: Studies were conducted in toddlers’ and children’s natural eating environment (nursery and school canteen), at their usually scheduled lunch and/or snack times. Results: Concerning sucrose, the add…
An interpretive framework for assessing and monitoring the sustainability of school gardens
2016
School gardens are, increasingly, an integral part of projects aiming to promote nutritional education and environmental sustainability in many countries throughout the world. In the late 1950s, FAO (Food and Agriculture Organization) and UNICEF (United Nations Children's Fund) had already developed projects to improve the dietary intake and behavior through school and community gardens. However, notwithstanding decades of experience, real proof of how these programs contribute to improving sustainability has not been well-documented, and reported findings have mostly been anecdotal. Therefore, it is important to begin a process of collecting and monitoring data to quantify the results and …
Biomonitoring of glyphosate and AMPA in the urine of Spanish lactating mothers
2021
The objectives of this study were to evaluate the urinary levels of Glyphosate (Gly) and its metabolite aminomethylphosphonic acid (AMPA) in Spanish breastfeeding mothers (n = 97), to identify the main predictors of exposure and to perform a risk assessment. Urine samples were analyzed using a method based on solid phase extraction and liquid chromatography tandem mass spectrometry (LC-MS/MS) determination. The developed method showed limits of quantification of 0.1 μg/L for both analytes. The detection frequencies (DFs) were 54% for Gly and 60% for AMPA, with geometric means (GMs) of 0.12 μg/L and 0.14 μg/L, respectively. In the statistical analysis, no relationship was found between the u…
Biomonitoring of parabens in human milk and estimated daily intake for breastfed infants
2020
In this study, we assessed the presence of four parabens in human milk of 120 mothers from Valencia (Spain) which took part in a human biomonitoring project (BETTERMILK). The detection frequency ranges of parabens were 41-60% and 61-89% for unconjugated- and total (unconjugated + conjugated)-parabens, respectively. The concentrations ranged from <LoQ to 31 ng/mL and from <LoQ to 49 ng/mL for unconjugated- and total-parabens, respectively. The frequency of use of some cosmetic products and human milk protein levels were the main predictors of parabens in milk. The study evidences the presence of both conjugated and unconjugated paraben forms in human milk. The newborns estimated daily intake…
Valoración de la ingesta dietética a nivel poblacional mediante cuestionarios individuales: sombras y luces metodológicas
2007
El desarrollo de la moderna metodología necesaria para caracterizar con rigor la ingesta de individuos y poblaciones data de hace sólo dos décadas, cuando germinó la epidemiología nutricional. La razón del carácter reciente de esta disciplina radica en el hecho de que la valoración de la ingesta dietética a nivel poblacional presenta retos complejos, que sólo van siendo superados a medida que investigamos y mejoramos los instrumentos metodológicos disponibles. En el presente artículo se revisan los métodos alternativos para estimar la ingesta de alimentos y nutrientes en los individuos. Tras una sucinta descripción de los métodos indirectos y directos de valoración del consumo alimentario, …
