Vitamin D and Disease Incidence Prevention

Vitamin D is associated withVitamin D is associated with disease prevention i.e. the chart from Grassrootshealth's website and prepared by Garland and Baggerly shows that breast cancer incidence is reduced by 30% when the vitamin D serum level is 34 ng/ml vs. the baseline of 25 ng/ml. There is an 83% reduction in incidence when the serum level is 50 ng/ml vs. the baseline of 25 ng/ml. Thus, the chart shows that higher vitamin D blood levels may help in the prevention of several diseases.
