Une consommation quotidienne de raisin pourrait renforcer la protection cutanée au niveau génétique

De nouvelles découvertes montrent que manger l'équivalent de trois portions de raisin par jour pendant deux semaines peut modifier l'activité des gènes dans la peau humaine. Ces changements semblent renforcer la barrière externe de la peau et réduire les signes de stress oxydatif après une exposition à de faibles doses d'ultraviolets.

Les volontaires de l'étude ont consommé du raisin quotidiennement pendant deux semaines. Les chercheurs ont ensuite mesuré l'expression génique de leur peau avant et après cette période, avec et sans exposition aux ultraviolets. Si les schémas d'activité génique différaient d'une personne à l'autre et évoluaient avec le temps, la consommation de raisin a produit des effets constants chez tous les participants.

Preliminary research from USC Norris Comprehensive Cancer Center, presented at the American Association for Cancer Research (AACR) annual meeting, found that non-smokers diagnosed with lung cancer before age 50 reported eating more fruits, vegetables and whole grains—and had higher overall Healthy Eating Index scores—than the U.S. population average. The researchers emphasized that the results do not prove diet causes lung cancer and said a possible explanation could involve environmental exposures such as pesticides, a hypothesis that requires direct testing.

Polyphenols, natural plant compounds acting as antioxidants, help reduce inflammation and support health, according to experts cited in a Vogue article. Registered dietitians recommend incorporating berries, dark chocolate, coffee, artichokes, apples, nuts, seeds, and herbs. These foods provide varying amounts of polyphenols, with benefits linked to disease prevention.

A new study from the Environmental Working Group finds that consuming more fruits and vegetables with higher pesticide residues, such as strawberries, spinach, and bell peppers, correlates with increased pesticide levels in urine. The research underscores diet as a primary exposure route while emphasizing the health benefits of produce. Findings highlight needs for better monitoring of cumulative pesticide effects.

Researchers at Israel's Weizmann Institute of Science have determined that genetics explain about 50% of differences in human lifespan, far more than previously estimated. The finding, published in the journal Science, challenges earlier views that placed genetic influence at 20-25% or less. By analyzing twin data and filtering out external death causes, the team uncovered this stronger hereditary role.
