7 sunscreen mistakes that could be damaging your skin: Keep your skin sun-safe

Researchers found that three daily servings of grapes for two weeks changed skin gene activity and lowered a marker of UV-related oxidative damage.

  • A large study suggests that eating three helpings of grapes daily for two weeks may help reduce sun skin damage, complementing other protective measures like SPF sunscreens and hats.
  • Grapes are rich in polyphenols, known antioxidants present in the fruit's skin and seeds that neutralize unstable free radicals damaging cells during metabolic processes.
  • Gene expression analysis revealed that grape consumption consistently altered patterns in every participant, specifically affecting genes involved in keratinization, the process producing skin's outer protective layer.
  • After low-dose ultraviolet exposure, volunteers who ate grapes showed lower levels of malondialdehyde, a chemical marker of oxidative stress, suggesting benefits for the body's largest organ.
  • Interestingly, researchers suggest that grape consumption might also influence gene expression in other organ tissues, including the liver, kidney, and brain, indicating broader physiological impacts.
