The Sun And Vitamin D

Since sun and vitamin D are closely related, we must also know the foods that have plenty of vitamin D. Cod liver oil, sardines, herring, salmon, tuna, milk, cheese, eggs, fortified margarine etc are the food items that are rich in vitamin D. If you don’t get enough exposure to the sun and live in such a country where there are very small days, then it is recommended for you to include these items in your diet. Too much of exposure to the sun will result in sunburns and excess vitamin D. This excess vitamin D increases the phosphate and calcium levels in the body that result in kidney stones, muscle weakness, upset stomachs and unusual thirst. Sometimes it can also create growth problem in children.Studies have shown that Vitamin D and sunlight always go together but there are harmful affects of sun’s UV rays as well. The extra exposure to the sunlight can cause skin cancer in many people. Other studies and articles about sun and vitamin D show that the manufacturing of vitamin D helps in preventing certain amount of cancers. Vitamin D is produced which helps in limiting the overproduction of cells. It doesn’t mean that we should roam around without wearing sun block. The maximum time that you can spend in sun without wearing sunscreen is 10 to 15 minutes.
