The benefits of vitamin d are quickly spreading and the news just keeps getting better. Research has shown for awhile that the "sunshine vitamin" can increase calcium absorption, thus building strong bones
New studies published in 2007 suggests that the vitamin d has multiple other benefits: diets which are high in vitamin D may ward off diabetes, gum disease and multiple sclerosis and even cancer. The news on colon cancer is even more promising.
A large trial study showed men in the Health Professionals Follow-Up Study and women in the Nurses' Health Study who had the highest blood levels of vitamin D were half as likely to develop colon cancer as their peers with lower vitamin D.
Dr. Louise Parker, an epidemiologist and a world expert in the environmental exposures that can lead to cancer, says 1,000 units a day is well beyond what you can obtain from your diet. Vitamin D is a bit of a rare vitamin, appearing only in fatty fish, cod liver oil and egg yolks. Even if you were to sunbathe in southern climates, you would not take in 1,000 units.
“If you were to lie naked on a beach in the Bahamas, and I don’t recommend that because of skin cancer, you cannot get up to the equivalent of 1,000 units of Vitamin D a day,”say Dr.Parker
