Consumo diário de uvas pode melhorar a proteção da pele em nível genético

Novas descobertas mostram que ingerir o equivalente a três porções de uvas por dia durante duas semanas pode alterar a atividade genética na pele humana. As mudanças parecem fortalecer a barreira externa da pele e reduzir sinais de estresse oxidativo após exposição a baixas doses de raios ultravioleta.

Voluntários no estudo consumiram uvas diariamente por duas semanas. Os pesquisadores então mediram a expressão gênica em sua pele antes e depois do período, tanto com quanto sem exposição ultravioleta. Os padrões de atividade genética diferiram entre as pessoas e mudaram ao longo do tempo, mas o consumo de uvas produziu efeitos consistentes em todos os participantes.

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.
