Less risk of skin cancer with the assumption of vitamin A


LESS RISK OF SKIN CANCER WITH THE ASSUMPTION OF VITAMIN A

The data of a study on 170,000 people reveal that the spinocellular carcinoma, a type of skin cancer, is less frequent in those who follow a diet rich in vitamin A deriving from fruits and vegetables.

What does this study say exactly?

“Skin tumors are difficult to prevent, including  spinocellular carcinoma. This study suggests that following a healthy diet, especially rich especially in Vitamin A can be a way to lower the risk of course continuing with good habits as the use of adequate solar filters and limiting the exposure to the sun”.

Dr Eunyoung Cho, professor of Dermatology and epidemiology at the Brown University and the Brigham and Women’s Hospital has summarized the contribution of the work done with the citation above. His research group has analyzed more than 170,000 people followed for about 25 years, were eating habits and other crucial information was recorded for the risk of skin tumors, such as the colour of skin and hair, important sunburn, cases of disease in the family. The result showed that those who regularly consumed foods rich in vitamin A had a lower risk of about 17 per cent to develop a spinocellular carcinoma with respect to the group who consumed less.

Researchers have explained that a high level of vitamin A corresponds for example to an average size sweet potato (or American) or two large carrots per day, while the lowest level to a third of a cup of fried sweet potatoes or a small carrot per day.

The observed data obviously reflect the vitamin A obtained from plant sources (green leaf vegetables, carrots, potatoes, apricots, melons) more than from animal sources or from supplements. Indeed, specify the researchers:

“An excess of vitamin A from animal sources and by supplementation may lead to nausea, liver problems, increase the risk of osteoporosis and hip fracture”. Vitamin A, or also called retinol, is useful to the health of your eyes, bones and teeth, as well as for the proper functioning of the immune response. The authors of the study also specify that today we know that vitamin A is necessary for the growth and maturation of the skin cells, but there are no clear results with regard to the protection of the skin tumors.

LESS RISK OF SKIN CANCER WITH THE ASSUMPTION OF VITAMIN A BUT WHERE IS IT LOCATED?

The study also tells us that we encounter less risk of skin cancer with the assumption of vitamin A, lets see where it is mostly found.

Vitamin A is located in food of animal origin (liver, cod liver oil, butter and cheese, eggs), while in foods of vegetable origin are its precursors, carotenoids  (carrots, apricots, pumpkin, dandelion, rocket salad (rucola), basil, tomatoes, spinach, peaches and many others). Also the work, described on the pages of the Journal of the American Medical Association of Dermatology, offers very significant data in this sense but obviously further research is required, hence this is a further reason to eat more fruits and vegetables.
