El consumo diario de uvas podría mejorar la protección de la piel a nivel genético

Nuevos hallazgos demuestran que consumir el equivalente a tres porciones de uvas al día durante dos semanas puede alterar la actividad genética en la piel humana. Los cambios parecen fortalecer la barrera externa de la piel y reducir los signos de estrés oxidativo tras una exposición a dosis bajas de luz ultravioleta.

Los voluntarios del estudio consumieron uvas diariamente durante dos semanas. Posteriormente, los investigadores midieron la expresión genética en su piel antes y después del periodo, tanto con exposición a luz ultravioleta como sin ella. Aunque los patrones de actividad genética variaron entre las personas y cambiaron con el tiempo, el consumo de uvas produjo efectos consistentes en todos los 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.
