Demand that Dairy Producers Disclose Risk of Cancer on Labels

Target: Margaret Hamburg, Commissioner of Food and Drugs

Goal: Demand that adverse health effects of consuming animal proteins are disclosed on dairy product labels.

For decades, milk has been a staple of the American diet. Until the last century, however, few people were able to afford milk and dairy products on a regular basis. This idea coupled with the growing rates of cancer in industrialized nations led researchers to question how consumption of animal proteins really effects the human body. T. Collin Campbell and his associates conducted a study that lasted 20 years to determine what impact regular consumption of dairy has on human health. In their ‘China Study,’ they found that cancer rates were highly correlated to the amount of animal protein consumed.

Campbell tested this theory on animal subjects as well. He found that the animal protein which is most prevalent in milk, Casein, caused high rates of cancer when fed to rats. Conversely, none of the rats that received less than 5% animal protein in their diet developed cancer. He also discovered that people in the Philippines and China were far more likely to develop cancer when they could afford to purchase dairy, and particularly milk, on a regular basis. A study at Harvard replicated these results, although some researchers have speculated that the reason for the increased risk of cancer could be caused by the hormones and antibiotics given to dairy cows. Either way, consuming animal proteins every day greatly increases the likelihood of developing cancer. This is something the public should be aware of.

Consumers expect that the Food and Drug Administration will inform the public of any potential health risks related to food, particularly a staple food item such as milk. Please sign this petition to ask the FDA to require dairy producers to disclose the risk of cancer on product labels.


Dear Margaret Hamburg,

T. Collin Campbell and his associates recently published a study, which included data from 20 years of research on the effects of animal protein on the human body. Campbell discovered through extensive animal testing and human observation that consumption of the animal protein, Casein, is highly correlated with cancer. In his book, The China Study, he details how one group of rats was fed a diet high in animal protein, while a control group was given far smaller amounts. The rats fed a high protein diet developed cancer at alarming rates, while the rats fed less protein developed no cancer. This is only one example of the many studies he conducted to determine the adverse health effects of consuming animal proteins on a regular basis.

Milk contains 85% animal proteins, and a high rate of the protein Casein. Consuming this protein on a regular basis has been linked to the development of cancer, not only in animal subjects, but in several human populations as well. Researchers at Harvard University also found that animal proteins, in conjunction with growth hormones and antibiotics, are highly correlated to cancer in humans.

Given this information, it is obvious the public deserves to know about the potential risks of cancer from consuming dairy products, so that they can decide for themselves whether or not to purchase these goods. Consumers trust the Food and Drug Administration to disclose the risks and warnings of products found on American shelves. Please require dairy producers to disclose the risks of cancer from the consumption of animal protein on their labels.
