The U.S. Food and Drug Administration approved the use of rBGH in 1993. Despite FDA approval of rBGH, this hormone has been the subject of substantial independent scientific studies that conclude it does pose a serious risk to human health. Other studies contradict these findings; however they tend to be produced by the industries that benefit from the use of rBGH.

rBGH , Health Dangers

Independent scientists have studied the effects of rBGH on health. According to Samuel S. Epstein, M.D., author of the book, "What's in Your Milk" and of several internationally recognized scientific journal articles on rBGH, use of this hormone is a serious potential risk factor for cancer.

Milk from cows treated with rBGH contains significantly higher levels of a hormone called insulin-like growth factor-1 (IGF-1). Experiments have shown that at higher than normal biological levels, IGF-1 is linked to cancer in humans, particularly cancers of the breast and prostrate, but also others.

Infants and children may be even more susceptible to the harmful effects of high levels of IGF-1 because intake of higher levels of IGF-1 in milk results in a higher concentration given their smaller blood plasma volume. Some scientists have even suggested that future cancers could be "seeded" in youngsters exposed to high levels of IGF-1 in hormone treated milk.

Don't Be Fooled

Recombinant bovine growth hormone is designed to increase the yield of milk from each cow and thus increase efficiency and profitability of dairy producers' operations. Some industries that profit from the use of this hormone are found to make misleading statements about the safety of rBGH.

"IGF-1 is naturally occurring anyway."

Yes, IGF-1 is naturally occurring, but naturally occurring IGF-1 is found in significantly lower quantities than are found in milk from rBGH treated cows. In addition, the IGF-1 in milk from rBGH treated cows is found to be a more bioactive form.

"IGF-1 in milk cannot be absorbed by the human gut."

Not true. In both humans and rats, studies have shown that many proteins, including IGF-1, are absorbed intact into the blood stream. Furthermore, an infant's gut is more permeable to these proteins.

"IGF-1 from cows doesn't have the same effect as human IGF-1".

Nope. IGF-1 is a protein hormone that is made up of a particular sequence of amino acid building blocks. The amino acid sequences of these proteins are identical. As such, IGF-1 from treated milk can fully interact with and affect human cells.
