Nutritional Myth #8: Growth hormone (rBGH) is of no conern in milk.

cows on rbghNutrition Myth #8: Growth hormone (rBGH) is of no concern in milk.  It is injected into cows to increase milk production and does not enter the milk.  TRUTH: Consider this: back in 1930, the average dairy cow produced 12 lbs. (1 ½ gal) of milk per day.  By 1988, the average was 39 lbs. per day.  This was done by selective breeding to obtain dairy cows that produced a lot of pituitary hormones, thus producing large amounts of milk.  Today, a synthetic growth hormone (rBGH) is injected into these dairy cows bringing the average up to 50 lbs. of milk/day.

This sounds great for the dairy farmers, right?  However, messing with Mother Nature comes with consequences.  It has been shown that cows injected with rBGH are 79% more likely to contract mastitis.  This, along with other problems, required an increased need for antibiotics.  Consumers’ Union reports that because of increased udder infections, it is more likely that milk from rBGH treated cows will be of lower quality – containing more pus and bacteria – than from untreated cows.

Bovine growth hormones are not natural and can cause many problems in humans as they have in cows.  The rBGH hormone has been found in the milk from the Bovine injected cows.  rBGH can be absorbed from the milk into the blood producing hormonal and allergic effects – particularly in infants and children.  Increased levels of cell stimulating growth factors have been found in rBGH milk.  These could induce premature growth and breast stimulation in infants and possibly promote breast cancer in adults.

Increased bacterial infections in rBGH cows require treatment with antibiotics that will pass into the milk.  This is likely to result in antibiotic – resistant infections in the general population.  Also, steroids and adrenaline-type stressor chemicals induced in cows by these hormones are likely to contaminate the milk and may be harmful, particularly to infants and young children.

The FDA has ignored the large amount of evidence that associates increased consumption of insulin growth factor-1 (IGF-1), which increases in milk from rBGH treated cows, with a potential risk of breast cancer and other types of cancer.

Published research shows that rBGH use on dairy cows induces a marked and sustained increase in the levels of IFG-1 in cows’ milk.  One report found a tenfold increase of IGF-1 in the milk of rBGH treated cows.  They also found the IGF-1 in rBGH milk is more bioactive than in non-hormonal milk.

IGF-1 is NOT destroyed by pasteurization.  In fact this process increases the IGF-1 levels in milk.  The FDA admits that IGF-1 is readily absorbed across the intestinal wall and into the bloodstream.  It can then affect other hormones.

Researchers have found IGF-1 induces rapid division and multiplication of normal human breast epithelial in tissue cultures.  It is highly likely that IGF-1 promotes transformation of normal breast epithelium to breast cancers.  Moreover, IGF-1 maintains the malignancy of human breast cells, including their invasiveness and ability to spread to distant organs.  IGF-1 has also been similarly associated with colon cancer.

After careful examination of the potential negative effects of recombinant bovine growth hormone (rBGH) milk on human health, it has been banned in Canada, Australia, Japan and the European Union.  Yet, it is used EXTENSIVELY by the dairy industry in the United States.  You may ask why?  I say it’s the big dollars of the Monsanto’s and other involved companies that dictates the FDA rulings – NOT OUR HEALTH!

    It’s somewhere between “drives me nuts” to “ticks me off” when I see on the front of dairy products the label “Made from cows not treated with rBGH- bovine growth hormone” and then on the back the idiotic statement about how there is no significant difference between treated and non-treated milk.

    BS! All these years with us eating animal products with no regard to hormones I’m convinced is causing not only reproductive issues, but the reason kids seem to be going through puberty at younger and younger ages…. not to mention all the diseases that are hormone-based, like diabetes. Between this and HFCS, no wonder it’s an epidemic.

    And I have serious issues with HFCS. I’m going to have to search your site for an article on that to agree with. :D I have extreme dislike for the corn industry’s new “Sugar is sugar- don’t be hatin’ on the HFCS” campaign. UGH
