Introduction: Food Exchange Lists (FELs) are a user-friendly tool developed to help individuals aid healthy eating habits and follow a specific diet plan. Given the rapidly increasing number of new products or access to new foods, one of the biggest challenges for FELs is being outdated. Supervised machine learning algorithms could be a tool that facilitates this process and allows for updated FELs-the present study aimed to generate an algorithm to predict food classification and calculate the equivalent portion.

Introduction: antioxidants play an important role in the antioxidant defense system. Obesity and the aging process increase oxidative stress. The disruption of the oxidant-antioxidant balance towards oxidant condition could be related to cognitive and physical disabilities.

This article takes a historical perspective combining 3 illustrative examples of the origins of the community health worker (CHW) model in Mexico, as a community-based participatory strategy. Three examples were identified from the sparse literature about CHWs in Mexico emphasizing their key roles and functions in various community settings. The CHW models illustrate what is known of training-development and planning, implementation, and evaluation of the CHWs model in different settings addressing cardiovascular disease and risk factors.

Background/aim: Genetic variation in apolipoprotein E (ApoE) has a key role in lipid metabolism. However, its contribution to the amount and distribution of body fat is under investigation. The aim of this study was to analyze the association between genetic variation in ApoE and obesity-related traits in Mexican school children.

Introduction: In Mexico, cardiovascular disease and its risk factors are growing problems and major public health concerns. The objective of this study was to implement cardiovascular health promotion and disease prevention activities of the Salud para su Corazón model in a high-risk, impoverished, urban community in Mexico City.

Methods: We used a pretest-posttest (baseline to 12-week follow-up) design without a control group.

Aim: To evaluate the ability of five clinimetric instruments to discriminate between subjects >60 years of age living at home versus those living in a residency.

Methods: Trained nutritionists applied five instruments (cognition/depression/functionality/nutrition/appetite) to 285 subjects with majorities of women (64%), aged <80 years (61%), and home residents (54%).

Results: Multivariable regression models were generated for each instrument using age, gender, and residency as independent variables.

Article Synopsis
  • Oxidative stress contributes to obesity-related health issues, and the MTHFR enzyme, influenced by its C677T genetic variant, may play a role in this process by affecting folate metabolism and homocysteine levels.
  • The study aimed to assess the frequency of the C677T SNP in the MTHFR gene, evaluate the intake of vitamins B6, B9, and B12, and measure lipid hydroperoxide levels in obese and non-obese individuals.
  • Findings indicated no significant difference in the C677T variation or vitamin consumption between normal-weight and obese groups, but there was a notable increase in lipid hydroperoxide levels in the obese group, highlighting oxidative stress across obesity levels.

Article Synopsis
  • The study aims to compare different predictive formulas for calculating resting energy expenditure (REE) against indirect calorimetry in Mexican women with varying grades of obesity (I to III).
  • Findings indicate that the Harris-Benedict, World Health Organization, and Valencia formulas provided REE estimates with good accuracy (around 63-67%), while other formulas like Mifflin and Institute of Medicine had lower accuracy (53-58%).
  • For women with grade III obesity, the Valencia and "Formula Rápida" had the highest accuracy in estimating REE, making them more reliable options for this demographic.

According to PAHO and WHO, supplementary feeding is the process that begins when human milk is insufficient to meet the nutritional needs of an infant and requires other foods and liquids. The decision to begin complementary feeding depends on socio-economic, physiological, nutritional and psychological factors. The maturation of the neuromuscular, gastrointestinal and renal system influences the chances of success of supplementary feeding.

Fruit and vegetable intake may reduce the risk of some chronic diseases. However, many children consume less-than-recommended amounts of fruit and vegetables. Because health professionals and dietetics practitioners often work with parents to increase children's fruit and vegetable intake, assessing their opinions about the effectiveness of parenting practices is an important step in understanding how to promote fruit and vegetable intake among preschool-aged children.
