Tomatoes have the power to ward off skin cancer risk, say scientists!

Tomatoes are a global staple and can be found in every kitchen across the world. In solid or liquid form, tomatoes are quite versatile when it comes to the culinary arts.
Even in the health department, 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.
A study has further cemented these benefits and encouraged daily consumption of tomatoes saying that it cuts skin cancer tumour development.
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.
"This study showed us that we do need to consider sex when exploring different preventive strategies," said Tatiana Oberyszyn, a professor at Ohio State.
"What works in men may not always work equally well in women and vice versa," said Oberyszyn.
Previous human clinical trials suggest that eating tomato paste over time can dampen sunburns, perhaps thanks to carotenoids from the plants that are deposited in the skin of humans after eating, and may be able to protect against UV light damage, Cooperstone said.
"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.
