Diet rich in tomatoes may cut skin cancer risk: study
Tomato consumption was found daily to reduce the development of skin cancer tumors in half in mice, according to scientists.
Researchers at Ohio State University in the US Found that male mice fed a diet of 10% tomato powder daily for 35 weeks and then exposed to ultraviolet light, experienced an average of 50% of skin cancer tumors compared to mice having eaten dehydrated tomato .
The relationship between tomatoes and cancer is that dietary carotenoids, pigmented compounds that give color to tomatoes, can protect the skin from damage to ultraviolet (UV) rays, said Jessica Cooperstone, co-author of the study published In the journal Scientific Reports.
There was no significant difference in the number of tumors in female mice in the study, according to the researchers.
Previous research has shown that male mice developed tumors earlier, after UV exposure and their tumors are more numerous, larger and more aggressive.
“This study showed us that we must take gender into account when exploring different prevention strategies,” said Tatiana Oberyszyn, a professor at Ohio State.
“What works for men may not always work so well in women and vice versa,” Oberyszyn said.
Previous clinical trials in humans suggest that tomato paste consumption over time can absorb sunburns, perhaps because of carotenoid plants that deposit on the skin of humans after eating, and can be protected against damage Caused by UV rays, Cooperstone said.
“Lycopene, the main carotenoid in tomatoes, has proven to be the most effective antioxidant of these pigments,” he said.
“However, comparing lycopene administered from a whole food (tomato) or synthesized supplement, tomatoes appear to be more effective in preventing redness after UV exposure, suggesting that other compounds tomatoes may also be at play, Cooperstone said.
In the new study, researchers found that only male mice fed dehydrated red tomatoes had a reduction in tumor growth.
Those fed diets with mandarin tomatoes, who demonstrated that they were higher in bioavailable lycopene in prior research, had fewer tumors than those in the control group, but the difference was not statistically significant. PTI SAR SAR
