- A new study finds that grapes may reduce the chances of sunburn for some people.
- The cause of sunburn—UV radiation from the sun—is implicated in the development of skin cancers.
- The study suggests that microbiome differences may explain why grapes reduce some peoples’ sensitivity to UV exposure and not others.
Some people become less sensitive to the damaging effects of the sun’s ultraviolet (UV) rays after consuming grapes, according to a new study in humans.
A third of the study’s participants became less prone to skin-reddening from UV rays after two weeks of eating three servings of grapes daily in powdered form.
For some individuals, the protective effect lasted a month after the grape consumption ended.
The difference between those who were less likely to get sunburned and others appear to be differences in their
The study is published in Antioxidants.
It was partly funded by the California Table Grape Commission, which had no other involvement in the research. One of the authors was a member of their scientific advisory committee.
According to the Skin Cancer Foundation, more than 9,500 cases of skin cancer are diagnosed daily in the U.S. More than two people die of skin cancer every hour.
Over-exposure to UV radiation is the cause of about 90% of non-melanoma cancers—including basal cell and squamous cell cancers—and is considered a major factor in melanoma. Non-melanoma cancers can typically be managed.
Burning your skin in the sun five or more times doubles your risk of melanoma. One blistering sunburn in childhood or adolescence can also double your risk.
The American Cancer Society predicts 97,610 new melanoma diagnoses in the U.S. this year, and that 7,990 people will die from the disease. Early detection of melanoma increases the chances of survival.
