Know "D" truth
In your body, you have 300 million cell duplications a day. When something goes awry with those duplications, your risk of cancer increases. Luckily, you have a gene—called the p53 gene—that looks for typos in those duplications to correct problems before they start. Vitamin D helps the p53 gene do its job.

You need 800 international units of vitamin D a day to decrease cancer rates. Get it in skim or soy milk, fortified foods, supplements, or with 20 minutes a day of summer sun or winter sun south of Los Angeles. Now, what does this have to do with your heart and arteries? Vitamin D not only seems to help turn on the genes that kill cancer cells, it also kills the cells making plaque in your arteries grow abnormally bigger.
