- New study finds grapes may reduce chances of disease Sunburn for some people.
- The ultraviolet radiation from the sun that causes sunburn is skin cancer.
- This study suggests that differences in the microbiome may explain why grapes reduce sensitivity to UV exposure in some people and not in others.
A new study in humans shows that after eating grapes, some people become less sensitive to the harmful effects of the sun’s ultraviolet (UV) rays.
One-third of the study participants had less UV-induced skin redness after eating three servings of powdered grapes daily.
In some individuals, the protective effect persisted for 1 month after consuming grapes.

The study was funded in part by the California Table Grape Board, which was not otherwise involved. One of the authors was a member of the Scientific Advisory Board.
by skin cancer foundationIn the United States, more than 9,500 cases of skin cancer are diagnosed every day, and more than 2 people die from skin cancer every hour.
Excessive UV exposure is responsible for about 90% of non-UV.melanoma It causes cancers such as basal cell carcinoma and squamous cell carcinoma and is considered a major factor in melanoma. Nonmelanoma cancers can usually be managed.
Burning your skin five or more times in the sun doubles your risk of melanoma. Even one blistering sunburn during childhood or adolescence can double your risk.
The American Cancer Society predicts that there will be 97,610 new melanoma diagnoses in the United States this year and 7,990 people will die from the disease. Early detection of melanoma increases the chances of survival.
Latest information on UV damage caused by LED nail dryers
Dermatologist Dr. Beth G. GoldsteinHowever, although he was not involved in the study, he said, “It clearly documents damage to cell lines that cause extensive oxidative damage and yield cell markers found in skin cancer.” rice field.
Dr. Goldstein says more epidemiological studies are needed to fully understand the risks of manicure dryers, but she recommends using them less frequently.
“Infrequent use a few times a year probably isn’t too much of an issue. [as] Using it every two weeks is not uncommon. “
“There are alternative nail products such as dip powders and options that don’t require UV light to cure and don’t cause the kind of skin damage you might think these devices can cause,” says Dr. Goldstein. .
2021, approx. 6.05 million A large amount of grapes were produced in the United States. inflammationcancer, gastrointestinal health, central nervous system effects, osteoarthritis, bladder function, and vision, according to new research.
Lead author of the study, Dr. John PezutoProfessor and Dean of Western New England University in Springfield, Massachusetts, explained his interest in studying grapes: Medical news today.
“Years ago, I
“In addition to relatively small amounts of resveratrol, grapes contain even more resveratrol. phytochemicalso it makes sense to investigate the health benefits of whole grapes,” he added.
Research into the role of grapes as a protective agent against skin cancer dates back more than a decade, with the first human trials.
In the current study, 36 people were enrolled, of whom 7 (19%) dropped out and 29 participants left complete data. Thirteen were female and 16 were male, with ages ranging from 24 years for him to 55.7 years for him.
The group was predominantly Caucasian (21), the rest Hispanic. The authors report that 25 participants were his type III and the rest were his type II.
The trial began with a 2-week diet period. This was followed by a two-week study period, during which individuals prepared two 36-gram packets of freeze-dried, ground seed and seedless red, green, and black grapes each day. This is equivalent to 3 servings of grapes (378g total).
Participants provided the researchers with fecal, urine, and blood samples at the end of the diet period, the end of the grape-eating period, and one month later. An ultraviolet irradiation sensitivity test was performed.
The analysis found that nine participants had decreased sensitivity to UV exposure at the end of the grape-eating period. Three of them were still effective after one month.
The findings were similar to, but not the same as, the 2021 findings. The authors speculate that the difference between Fitzpatrick skin types needs to be accounted for, and that people with lighter skin types may derive better UV protection from grapes.
The researchers looked for differences in samples of people the grapes had no effect on, those who exhibited short-term tolerance to UV radiation, and those who maintained tolerance longer. I was hoping to explain why the responses are different.
“People who showed greater tolerance to UV radiation showed the greatest differences in their microbiomes,” said Dr. Petzuto.
According to the study, the nine who achieved UV tolerance were “clearly distinguished from the remaining 20 volunteers by metabolomics and microbiomics analyses.”
Dr. Pezzuto added that there is, for example, a perfect correlation between resistance to UV radiation and decreased urinary metabolites indicative of UV-induced skin damage.
He noted that it was impossible to establish causation in the study, but “this strong correlation does not appear to be mere chance. Additional studies would be interesting.”
Dr. Pezzuto cautioned that his study “does not suggest, for example, that people should inadvertently avoid using sunscreen.”
“In my view, the broader implication of this research is the ability of human consumption of grapes to strengthen cellular systems that protect us from potentially harmful free radicals and reactive oxygen species.”
