The synthetic protein hormone rBST is used mainly by dairy farmers to increase the production of milk in cows and was approved by the FDA on November 5th, 1993. Bovine somatotropin (BST) is the natural form of growth hormone in cattle; rBST refers to BST that has been genetically engineered in a lab. The hormone stimulates the milk production of cattle by increasing the levels of IGF1, or a hormone known as insulin-like growth factor.
Posilac, Monsanto’s version of rBST, is used by farmers to increase a cow’s milk production. Posilac is applied to the cow’s udder approximately 50 days into the cow’s lactation. Posilac works by sustaining the mammary cells and limiting the rate of decrease of milk production after production peaks. The FDA determined BST safe for human health. However, public concern about BST relates to the fact that the form of BST given to cows is recombinant-derived from yeast or bacteria with BST gene from cattle that has been inserted into their genome or genetic material. Studies exist that suggest that large or inappropriate exposure to BST-like proteins are dangerous.
There is much controversy regarding rBST and its effect on human health. No biological side effects have been seen in humans who ingest the rBST present in cow’s milk; however, there have been some side effects for the cattle injected with rBST. One of these side effects includes an increased risk of mastitis, a type of udder infection. Several groups of consumers and researchers have expressed concern over the safety of ingesting any milk containing rBST. It is likely that rBST can make its way into the human body as a direct result of cow’s milk consumption. If the proves to be true, a variety of health problems can result in humans, including cancer, infertility, mastitis and others.
Traces of antibiotics or penicillin-based drugs used to treat mastitis in cattle may be found in cow’s milk. There are fears that such drugs in the milk could cause allergic reactions and an increase in IGF1 in humans. IGF1 also stimulates growth of intestinal cells, leading to abnormal intestinal growth. Consumers fear that IGF1 in milk may be carcinogenic to humans. In summary, livestock are fed and stuffed with dozens of medications, chemicals, foods of poor quality, potentially GMO-foods and are placed under tremendous stress. If you one should eat these foods they should not expect to maximize their health potential.
Dr. Michael Wald, author of his new book, Frankenfoods - Controversy, Lies & Your Health (available at Amazon.com), offers a riveting perspective of the GMO predicament exploring governmental and industry cover-ups, health dangers, environmental threats, GMO-free food plans and recipes, nutritional supplements and other practical solutions. Dr. Wald declares, "The GMO dilemma is here to stay and anyone interested in protecting their health and that of their loved ones, friends and the planet, must educate themselves and take political and personal action right now!" Considering the importance of this information Dr. Wald asks that you re-tweet his GMO links and follow him on Twitter - @DrMichaelWald. Thank you.
