The Truth About Hormone-Treatment in Whey - July 12, 2011


I’m sure if you would have told someone 50 years ago that we would be discussing the health risks associated with genetically engineered growth hormones in our milk, they would have thought you were crazy.  Why would we be injecting artificial hormones into our dairy cattle?

Here’s a Little Background for You

Bovine Somatotropin (BST or bST) is a naturally occurring hormone that triggers growth and lactation in dairy cows.  Artificial BST is produced using recombinant DNA technology (biotechnology), and called rBST (recombinant bovine somatotropin) for short.  The artificial hormone, also known as rBGH (recombinant bovine growth hormone) was introduced in 1994 and was marketed to increase milk production in dairy cattle by 10% over the course of 300 days, which is equivalent to 6-8 more pounds of milk produced each day.  This equals big money for the drug companies (an estimated 500 million annually worldwide), and an increase in profits for dairy farmers who are trying to maximize their production. img-4392.jpg

This Introduces Two Very Big Problems

One is for the health of the cattle, and the other is for the health of the consumer who is drinking the hormone-treated milk.  Studies have shown a whole variety of problems in cows being treated with rBST including; calf deformities, mastitis, infertility and lameness.  They also noted an overall decrease in body condition even though the cows were increasing the amounts of feed they were taking in.  Because of all these complications, farmers are routinely giving cows large doses of antibiotics, and the vicious cycle continues.

Studies have also shown that there is a compositional change in milk that has been treated with rBGH vs. untreated milk.  There is an increased amount of the hormone IGF-1 (Insulin-like Growth Factor), lower nutritional value (at different points in the cows cycle), and more pus in the treated milk.  Interestingly scientists have found that an increased level of IGF-1 in humans has been linked to breast and colon cancers. Whether there is a direct link between elevated levels in milk and cancer is not yet known as research continues. The FDA still stands behind its claims that the milk is safe to drink, relying on pasteurization to kill bacteria, hormones and antibiotics in the milk. However, IGF-1 is not denatured with pasteurization.

The Many Benefits of Fresh Raw Milk

The health and healing properties of raw milk are endless. Cow's milk is generally about 80% casein protein and 20% whey protein. This whey protein, considered the gold standard, contains the highest biological value of any protein you can put into your body. It provides us with an abundant source of essential amino acids and is a complete protein. The five major active proteins in whey are lactoferrin, immunoglobulins, bovine serum albumin, alpha-lactalbumin and beta-lactoglobulin.

What Sets our Whey Apart

The cows that produce the milk that becomes our Proserum are guaranteed to always be hormone-treatment-free. It is also tested to be free of any genetically modified materials. Our non-denatured year-round grass-fed whey protein is made from fresh raw milk that is then minimally processed to maintain all of the originally biological activity of the native proteins. Our ImmunoPro, RenewPro, Vital Whey and Bioactive Colostrum have the highest levels of active proteins to help support immune function (protects against bacteria, viruses, allergens), fight aging and provides the building blocks for muscle growth and repair.
