What if the simple fact of consuming grapes every day helped to preserve our muscles as they age? This is what a study published in the journal suggests Foods And led on 480 mice for two and a half years. Partly funded by California Table Grape Commission, this research highlights the deep genetic effects of a grape -enriched diet on muscle tissues.
2 portions of reason per day are enough
Sarcopenia, progressive loss of mass and muscle function, affects between 10 and 16 % of the elderly, especially women, especially after menopause. The study reveals that the daily addition of the equivalent of two portions of grapes in food leads to a significant modification of the expression of 25 muscle genes. In female in particular, researchers observed genetic reshaping that brought their profile closer to that of males, generally more resistant to muscle loss. “”This study brings convincing evidence regarding the genetic potential of grapes to improve muscle health“Explains Dr. John Pezzuto, principal and dean researcher at the Western New England University. He insists on the promise of future human applications, given the safety and availability of this fruit.
This fruit promotes muscle massage
Among the genes involved, some promote the growth of lean muscle mass, while others, linked to degeneration, see their activity reduced. If the “physical appearance of the muscles does not differ visibly, it is at the cellular level that the grapes seem to act, suggesting an upstream impact of the visible symptoms of sarcopenia. The grapes, with its more than 1,600 bioactive compounds, then appears as a” natural cocktail “whose combined effects could explain this beneficial genetic action. could promote muscle health.
A fruit with a thousand and one benefits
Beyond this study, the grape has already demonstrated its virtues for heart, renal, skin or even digestive health. This new research opens the way to potential targeted nutritional interventions to support the autonomy of the elderly.
However, researchers, however, call for caution: if these results are promising, human clinical trials are necessary to confirm the effect of grapes on muscle aging. In the meantime, the adoption of a food rich in fruit, combined with regular physical activity, remains the best strategy to maintain its vitality with age.
