take vitamin d to cut cancer risk

heard on the cbc last night and found the article to link to here:

Boost vitamin D supplements: Canadian Cancer Society

"We're recommending 1,000 IUs daily because the current evidence suggests this amount will help reduce cancer risk with the least potential for harm," said Heather Logan, the society's director of cancer control policy.

"More research is needed to clearly define the amount of Vitamin D that will maximize health benefits."

As more evidence on vitamin D becomes available, the society plans to update its recommendations.

Also Friday, a study published in the American Journal of Clinical Nutrition showed a 60- to 77-per-cent drop in cancer rates among postmenopausal women who took vitamin D combined with calcium, compared with a placebo.

Maps of UV Sunlight exposure correlate with incidence of Cancer and Multiple Sclerosis.

If you take NASA space satellite photos of North America and color code the UV sunlight exposure as Dr. Grant has done on his web site,, you will see a pattern remarkably similar to the incidence of cancer and multiple sclerosis. This is thought to be due to differences in Vitamin D levels. The farther north with less sun exposure and lower Vitamin D levels, there is an increased incidence of cancer and multiple sclerosis.

Diseases Caused By, or Associated With Vitamin D Deficiency:

Again here is the list: Osteoporosis, Hypertension, Cardiovascular disease, Cancer, Depression, Epilepsy, Type One Diabetes, Insulin resistance, Autoimmune Diseases, Migraine Headache, PolyCystic Ovary Disease (PCOS), Musculoskeletal and bone pain, Psoriasis, and chronic lymphocytic leukemia (CLL)(

Vitamin D deficiency has been reported in 57% of 290 medical inpatients in Massachusetts, 93% of 150 patients with overt musculoskeletal pain in Minnesota, 48% of patients with Multiple Sclerosis, 50% of patients with lupus and fibromyalgia, 42% of healthy adolescents, 40% of African American Women, and 62 % of the morbidly obese, 83% of 360 patients with low back pain in Saudi Arabia, 73% of Austrian patients with Ankylosisng Spondylitis, 58% of Japanese girls with Graves's Disease, 40% of Chinese adolescent girls, 40-70% of all Finnish medical patients.
