The moderating role of macronutrient intake in relation to body composition and genotoxicity: A study with gym users
In a cross-sectional study of gymnasium users (both sexes, ages = 41.9 ± 14.8 years), we examined the moderating role of macronutrient intake in relation to body composition and genotoxicity. A questionnaire was administered to evaluate characteristics of the participants. To assess macronutrient consumption, we used 24-h food recalls on three non-consecutive days. Body composition (body fat percentage and muscle mass) was evaluated with a bioimpedance scale. Genotoxicity was assessed with the buccal micronucleus cytome assay. Multiple linear regression models were applied, adjusting for age; sex; tobacco and alcohol consumption; and (with regard to exercise habits) frequency, training time, intensity, and types. Micronucleus frequency was directly associated with body fat and inversely associated with muscle mass. Our study shows that carbohydrate and fat intakes affect body fat percentage and micronucleus frequency in gymnasium users.
期刊介绍：
Mutation Research - Genetic Toxicology and Environmental Mutagenesis (MRGTEM) publishes papers advancing knowledge in the field of genetic toxicology. Papers are welcomed in the following areas:
New developments in genotoxicity testing of chemical agents (e.g. improvements in methodology of assay systems and interpretation of results).
Alternatives to and refinement of the use of animals in genotoxicity testing.
Nano-genotoxicology, the study of genotoxicity hazards and risks related to novel man-made nanomaterials.
Studies of epigenetic changes in relation to genotoxic effects.
The use of structure-activity relationships in predicting genotoxic effects.
The isolation and chemical characterization of novel environmental mutagens.
The measurement of genotoxic effects in human populations, when accompanied by quantitative measurements of environmental or occupational exposures.
The application of novel technologies for assessing the hazard and risks associated with genotoxic substances (e.g. OMICS or other high-throughput approaches to genotoxicity testing).
MRGTEM is now accepting submissions for a new section of the journal: Current Topics in Genotoxicity Testing, that will be dedicated to the discussion of current issues relating to design, interpretation and strategic use of genotoxicity tests. This section is envisaged to include discussions relating to the development of new international testing guidelines, but also to wider topics in the field. The evaluation of contrasting or opposing viewpoints is welcomed as long as the presentation is in accordance with the journal''s aims, scope, and policies.
