A new study led by Western New England University shows that long-term grape consumption can significantly enhance muscle health in both men and women by modifying gene expression. This finding could provide a new nutritional approach to combating age-related muscle decline.
A new study led by Western New England University (WNE) has revealed promising outcomes for muscle health through the long-term consumption of grapes. Published in the journal Foods, the research indicates that incorporating grapes into the daily diet can beneficially alter gene expression in muscle tissue for both men and women.
The study highlights that muscle health improvements were particularly significant in females, but both genders saw notable benefits.
By modifying gene expression associated with lean muscle mass and muscle degeneration, grape consumption could be a game changer in the battle against age-related muscle loss — a condition known to affect 10-16% of the elderly population.
“This study provides compelling evidence that grapes have the potential to enhance muscle health at the genetic level,” John Pezzuto, the senior investigator of the study and professor and dean of pharmacy and health sciences at Western New England University, said in a news release. “Given their safety profile and widespread availability, it will be exciting to explore how quickly these changes can be observed in human trials.”
Key Findings
Research findings illustrate that daily grape consumption induces significant changes in muscle gene expression, bringing male and female muscle characteristics closer together at a metabolic level. Genes related to healthy muscle were elevated, while those linked to muscle degeneration saw a reduction, suggesting enhanced muscle function.
This nutrigenomic approach could complement traditional strategies for muscle maintenance, such as regular exercise and high-protein diets.
The experts are particularly enthusiastic about the potential applications for combating sarcopenia, a condition characterized by age-related muscle loss. Techniques targeting gene expression through diet could provide a new frontier in nutritional science.
Study Overview
Nutrigenomics — the study of how diet impacts gene expression — played a crucial role in these findings.
Grapes, with their rich phytochemical content, were shown to offer disease-preventive properties through these mechanisms.
The study focused on the effects of consuming two servings of grapes per day, revealing a significant convergence of male and female muscle phenotypes when following this grape-rich diet.
Muscles naturally exhibit significant gender differences, but the study reported that grape consumption resulted in male and female muscles sharing similar metabolic parameters. The researchers noted elevation in genes associated with lean muscle mass and a decrease in genes linked to muscle degeneration.
The research team plans to delve deeper into the mechanisms behind these genetic changes and to understand the timeline for their effects. This evolving field could offer new strategies for maintaining muscle health across all age groups.
