Dairy Products and Prostate Cancer

Dairy Products and Prostate CancerOver the past 50 years, a number of studies have been done examining the link between dairy products and prostate cancer. While some believe the calcium in dairy products is to blame, other studies have found a link between bovine insulin growth factor (IGF-1) in dairy products and prostate cancer.

The Harvard School of Public Health has this to say: “A diet high in calcium has been implicated as a potential risk factor for prostate cancer. In a Harvard study of male health professionals, men who drank two or more glasses of milk a day were almost twice as likely to develop advanced prostate cancer as those who didn’t drink milk at all.”

A review of 12 studies done between 1966 and 2005 concluded that consumption of dairy products increased the risk of prostate cancer by 11% and consumption of calcium increased the risk of prostate cancer by 39%.

Several studies have found a link between prostate cancer and high levels of growth factor IGF-I in the bloodstream. IGF has also been linked to breast cancer and lung cancer.

IGF is a growth factor present in both human and cow’s milk that helps a newborn grow. It is intended to be consumed by babies during the nursing stage. When consumed by adults who are no longer growing, it has been found to stimulate growth of cancer and other abnormal cells. Humans are the only animals who consume milk after the nursing stage. The growth factors and nutrients contained in milk are suited to infants in the first years of life and not to adults.

Studies by Monsanto have found that use of rBGH in cows increases the amount of IGF-1 in cow’s milk, which means there are higher levels of growth hormone in commercially produced dairy products than even a newborn would receive from its mother.

One study found that vegans, who consume no dairy products or meat, have 9% lower levels of circulating IGF-I. Vegans also have lower rates of cancer than dairy and meat eaters.

Given the National Dairy Council’s marketing push to have every American consume three servings of dairy products per day in their “3 a day” campaign, it’s important to know that two separate studies found that adding three servings of dairy products to one’s diet per day was associated with a 10% increase in circulating IGF-1 levels.

The National Dairy Council is a lobby group and propaganda machine for the U.S dairy industry. Their job is to sell more dairy products. When they tell you to consume three servings of dairy per day, they aren’t doing it because they’re concerned about your health. They’re doing it because it lines the pockets of the dairy industry with money.

Many studies touting the benefits of milk have been sponsored by the Dairy Council. The Dairy Council is also a commercial sponsor of many consumer health publications that publish articles telling us to eat three servings of dairy products every day.

Perhaps we ought to take some advice from Arnold Schwarzenegger, who said: “Milk is for babies. When you grow up you have to drink beer.”
