MILK IS NOT A HEALTH FOOD

Gabe Mirkin, M.D.

What do you think when you see movie actors and athletes with a white mustache on their lips? Do you think that milk strengthens bones? There is little data to support any health benefits from drinking milk. I do not drink milk.

In 1977, The World Cancer Research Fund reported that milk may cause prostate cancer. Nobody noticed. This year, The Doctors study from Harvard Medical school showed that men who drink more than 4 glasses of milk per day are at higher risk for prostate cancer than those who drink less than that. The Harvard researchers explain that calcium in milk uses up vitamin D. Even though there is added vitamin D in milk, there is not enough vitamin D in milk to offset the loss of vitamin D caused by the calcium in milk. So regular milk drinkers have lower blood levels of vitamin D than those who do not drink milk. Lack of vitamin D causes cancer.

Neal Bernard, president of Physicians Committee for Responsible Medicine feels that milk increases blood levels of a hormone called insulin-like-growth-factor-1. Insulin-like -growth factor causes cancer cells to spread in the test tube and men with prostate cancer have higher levels of insulin like growth factor-1.

Furthermore, the data does not show that milk prevents osteoporosis (1). I have quoted several studies that show that osteoporosis is associated far more with taking in too much protein, than not getting enough calcium in the diet (2). Taking in too much protein causes the body to convert protein building blocks called amino acids into organic acids that acidify the blood. The kidneys respond by neutralizing the blood by taking calcium from bones and pushing it out through the urine. Furthermore, a recent study in the July journal, Pediatrics, shows that a high calcium intake does not strengthen bones in teenage girls. Further studies show that cow's milk contains cow's insulin that can sensitize susceptible infants to cow's insulin forcing the baby to make antibodies that attack the cow's insulin and these same antibodies attack the beta cells of the pancreas to cause juvenile diabetes (3). You can drink milk if you like, but you shouldn't think that it has any special health benefits.
