Dairy & Prostate Health

-

Prostate cancer (the aggressive type that requires treatment) incidence is increasing worldwide, particularly in areas in which the rich American diet is becoming more prevalent.  The disease is the second leading cause of death in men, and the most common cause of cancer death in non-smoking males.  

One of the major dietary culprits in increasing prostate cancer risk is dairy foods.  The Health Professionals Follow-up Study* included 47, 781 health care professionals and concluded that men who consumed more than two servings per day of cow’s milk products increased their risk of cancer by 60% more than those who consumed no cow’s milk.  More than 80% of the milk consumed by study participants was low-fat or no-fat milk, adding to the body of evidence that suggests that dairy protein is the major culprit.

Another study conducted by Giovannucci** concluded that higher calcium intake resulted not only in increased risk of cancer, but also higher risk of advanced and fatal cancers.  Men who consumed over 2000 mg of calcium per day had more than two times the risk of advanced or fatal cancer as compared to men who consumed less than 750 mg per day.  

The Physicians Health Study*** concluded that men who consumed 2.5 servings of dairy products per day had significantly increased risk of prostate cancer as compared to those who consumed less than .5 serving daily.

It appears that the prostate prefers a diet that excludes dairy foods and high calcium intake, and includes more fruits, vegetables, grains, legumes nuts and seeds.  In fact, Dean Ornish is currently conducting research on a low-fat vegan diet on prostate cancer patients with some positive preliminary results.  

In any case, this is further documentation for the case that cow’s milk is for cows, and that humans are best advised to stay away from it.
