Know the foods that contain vitamin D. There are some foods that are rich in vitamin d.
What food sources have vitamin d? Vitamin D is available only in some foods, but the best way to obtain vitamin D is through the exposure to sunlight.
It is available free of charge from sun light. Just daily sit for 20 minutes in sun, exposing around 15 per cent of the body (it could be hands or feet) to sunlight.
A person would have to drink ten glasses of vitamin D fortified milk each day just to get minimum levels of vitamin D into their diet.
Fatty fish like mackerel, tuna and sardines and fish liver oils are among the best sources. Small amounts of vitamin D are found in egg yolks, fortified milk, fortified dairy products, fortified cereals are good natural sources of D. The milk is fortified with 100 IU/cup of vitamin D, which is 25% of the Daily Value.
If you look at the food labels, you will not find the Vitamin D content, as the food labels are not required by law to list its content unless it has been fortified with vitamin D.
