Recombinant bovine growth hormone (rBGH) is injected into cows to increase milk production. It is a synthetic version of a natural hormone produced in a cow’s pituitary gland. This artificial version was developed by Monsanto from genetically-modified E. coli bacteria.
This hormone has been banned in 30 countries including Canada, Europe, Israel, Australia, Argentina, and New Zealand because it is considered unsafe. In fact, as far back as 1999, the UN Safety Agency unanimously ruled NOT to endorse its safety which has resulted in a ban on US milk internationally.
Studies have linked it to higher risks for cancer including prostate, breast, and colorectal cancer in humans. However, in the United States, where many believe our nation’s health is less important than profits, it remains on the market.
Cows also suffer with increased mastitis, arthritis, and other health issues.
To avoid this risky hormone, look for organic milk and dairy products including whey protein or at the very least look for the words “No rBGH.”
