A recent study out of Harvard reveals that one in five children between the ages of one and eleven, are not getting enough Vitamin D. We need vitamin D to help maintain calcium levels to keep our bones strong. It also turns out that this vitamin might help prevent serious diseases, including infections, osteoporosis, diabetes and even some cancers.
For people with food allergies, getting enough vitamin D may be challenging. In the U.S., milk is fortified with Vitamin D. For the dairy allergic, getting vitamin D by drinking milk is not an option. Turns out, milk alone (even 8 glasses a day!) is not an adequate source. A glass of milk typically contains 50-100 IU. We may need between 1,000 to 2,000 IU per day of vitamin D. Research is ongoing to pinpoint the daily requirement of Vitamin D.
Good natural sources of Vitamin D can be found in fatty fish such as salmon, tuna and sardines. Sunlight is a source of the vitamin as well. Of course excessive sun exposure can cause other problems, so be sensible.
If you're concerned about Vitamin D, talk to your doctor and see if a supplement might be beneficial.
