The consumption of broccoli is not only good for general health, but also combat the effects of ultraviolet radiation from the sun, revealed a study released today by the journal Proceedings of the National Academy of Sciences.

Scientists from Johns Hopkins University reported that the extract of the seeds of that vegetable, called sulforafane reduces redness of the skin and skin lesions to increase the production of enzymes that protect cells from radiation.

Until now we knew that broccoli is high in carbohydrates, vitamin C, vitamin A, potassium, folic acid, calcium and iron, all of which help to combat a long list of diseases.

It also contains antioxidants and fibre to prevent the increase in cholesterol and help regulate sugar and insulin in the blood.

The group of scientists managed to extract six people to test different doses in several areas of the skin exposed to ultraviolet radiation and compared the state of skin with untreated areas.

As indicated in its higher doses, the extract reduced the redness and swelling at an average of 37 percent, which ranged from eight percent to 78 percent, according to the ethnicity of participants.

  “This is important because it shows that (the seed extract of broccoli) is successful in humans,” said Dr. Paul Talalay, leader of the group, who recalled that these effects had already been confirmed in animals.

Talalay added that the extract can protect from ultraviolet radiation especially for people with problems in their immune system and are more at risk of skin cancer.

However, the scientist explained that it must not be replaced by solar blockers who are preventing radiation penetrates the skin cells.
