Bovine Growth Hormone Causes Cancer
On their own, cows can't produce enough milk to support a product — and profit — hungry diary industry. The solution: inject the cows with Bovine Growth Hormone (rBGH), which causes the cows to produce milk double-time. While the hormone does wonders for milk production, it isn't so great for the quality of the product. When cows produce more milk, there is more chance for infection, so cows on rBGH are typically on an amped-up regime of antibiotics. rBGH also increases the production of the Insulin-Like Growth Factor-1 hormone, which stimulates cell growth and may accelerate cancer cell growth in humans.
