Vitamin D necessary to fight disease

When members of our body's immune system called T cells encounter germs and viruses they change into "killer cells" and "helper cells".
A new study published today in Nature Immunology explains why Vitamin D is so important to our health.

"When a T cell is exposed to a foreign pathogen, it extends a signaling device of 'antenna' known as a vitamin D receptor, with which it searches for vitamin D," ...If there is an inadequate vitamin D level, they won't even begin to mobilize."

Most people lack enough Vitamin D

According to a recent study in the Archives of Internal Medicine, found that "77 percent of U.S. adults and teenagers surveyed did not have the estimated minimum healthful level of 30 nanograms per milliliter in their blood. And just three percent of blacks in the survey were getting enough of the vitamin."

Cod liver oil

While living with my parents, I was given a table spoon of cod liver oil, a bowl of oatmeal, and a half of an orange for breakfast each day. I might have to consider adding cod liver oil to my diet again (most people think it tastes nasty).

My boyfriend's mom gave us both two big bottles of Vitamin D supplements for Christmas this year. She works at a hospital, and one of the doctors there told her that especially in Northern latitudes, people tend to be deficient in this vitamin. He also said how important it is for health.

I wonder how taking supplements compares to cod liver oil? I agree - that sounds pretty gross.

I think your right about the taste being disguisting but not everything that is good for you taste good. Sometimes you just have to be health minded and take what's best for you no matter the smell.
