Among Vitamins, D Seems Short for 'Does a Lot'

Vitamin D helps bones and muscles to grow strong and healthy. But more and more research is suggesting that vitamin D might also help to prevent many diseases.

The easiest way to get vitamin D is from sunlight. The sun's ultraviolet rays react with skin cells to produce vitamin D. But many people worry about skin damage from the sun. As a result they cover their skin or wear sunblock or stay out of the sun. Not many foods naturally contain vitamin D. Foods high in this vitamin include oily fish such as salmon and tuna, and fish liver oils. Researchers reported that farmed salmon had only about one-fourth as much vitamin D as wild salmon.

Small amounts of D are found in beef liver, cheese and eggs. Research in the last several years has shown that low levels of vitamin D may increase the risk of heart attacks and cancer. Other studies have shown that people with rheumatic diseases often have low levels of vitamin D.

More doctors are now testing their patients for their vitamin D levels. But if people take too much vitamin D, it might act as a poison (яд).
