Tomatoes have power to ward off skin cancer risk: Study

ISLAMABAD: A study encouraged daily consumption of tomatoes saying that it cuts skin cancer tumour development.

According to Halth News, tomatoes have a wealth of benefits to offer, for instance, they prevent heart diseases, purify blood and remove toxins, lower bad cholesterol levels, improve eyesight, et al.

Researchers at Ohio State University in the US conducted an experiment on mice through which this conclusion was made.

The relationship between tomatoes and cancer is that dietary carotenoids, the pigmenting compounds that give tomatoes their colour, may protect skin against ultraviolet (UV) light damage, said Jessica Cooperstone, co-author of the study published in the journal Scientific Reports.

There was no significant difference in tumour number for the female mice in the study, researchers said.

Previous research has shown that male mice develop tumours earlier after UV exposure and that their tumours are more numerous, larger and more aggressive.

"What works in men may not always work equally well in women and vice versa," said Oberyszyn.

"Lycopene, the primary carotenoid in tomatoes, has been shown to be the most effective antioxidant of these pigments," she said.

"However, when comparing lycopene administered from a whole food (tomato) or a synthesised supplement, tomatoes appear more effective in preventing redness after UV exposure, suggesting other compounds in tomatoes may also be at play," said Cooperstone.

In the new study, the researchers found that only male mice fed dehydrated red tomatoes had reductions in tumour growth.

Those fed diets with tangerine tomatoes, which have been shown to be higher in bioavailable lycopene in previous research, had fewer tumours than the control group, but the difference was not statistically significant.
