How to get the intake of sunlight?
Sunlight provides 90 percent of the vitamin D your body needs. When the heat and ultraviolet light touches the skin, the production of vitamin D is activated. In food, the liver is the main natural source and fish oil. Eggs contain small amounts of vitamin D, as well as some foods such as cereals, fresh fruit juice and yogurt are fortified with vitamin D.
"A serving of fortified foods only provide nearly 20 percent of the daily requirement of vitamin D. It's hard to get all of their vitamin D from food alone," said Catherine Collins, a dietician at St George's Hospital, London, as reported by dailymail, Tuesday (31 / 1/012).
Many people avoid going out without wearing sunscreen and then end up with a deficiency of vitamin D. Research has found that people who were diagnosed with malignant melanoma, the most serious form of skin cancer, are those with the lowest levels of vitamin D.
To meet the ideal intake of vitamin D, exposure to sunlight on a regular basis during the summer is very necessary. Duration is about 10 to 15 minutes a day without sunscreen at 11:00 to 15:00, which is when the sun is hot-hot.
"Almost everyone in the country is deficient in vitamin D this year. We live too far north and was not sure the weather would clear enough to produce vitamin D is enough. Amount of vitamin D produced depends on how much skin terkana sun exposure. Arms and face is not enough, the arm is also necessary, "said Dr. Robert Moy, a pediatrician at Birmingham.
