In the last two years, IGF-I has been identified as the key factor in the growth and proliferation of various cancers including prostate cancer (Science - January, 1998), breast cancer (The Lancet - May, 1998), and lung cancer (Journal Of The National Cancer Institute - January, 1999).
However, scientists at the Food and Drug Administration have previously (incorrectly) argued that this powerful growth hormone in milk did not survive digestion and cannot alter human blood chemistry. Now that the evidence is in, the scientific community has proof of how wrong government regulators were in approving the genetically engineered bovine growth hormone (rbGH). Milk from cows treated with rbGH contains increased levels of IGF-I.
The Dairy Scientists
Robert Heaney, MD, is the senior author of the dairy industry-financed study. He co-published his paper with seven other researchers, including Suzanne Oparil, and Susan Barr. This trio is listed together on the reverse of a milk mustache brochure as "dairy experts." They have very strong ties to dairy industry dollars.
It is no coincidence that these three individuals participated in a new study, critical to the dairy industry. In order to continue to market their calcium milk myth, the dairy industry planned, financed, and now is promoting this study. On Friday October 1, 1999, a press release announced:
"Adding Milk To Daily Diets Slows Bone Breakdown In Older Adults"
The dairy industry-financed study was published in the Journal of the American Dietetic On page 1231 of the journal article, tucked away in a paragraph titled "Skeletal Effects," these dairy scientists reveal the truth about the powerful growth hormone contained in milk: "Serum IGF-I level increased significantly in the milk group and the difference between groups was highly significant.
Serum IGF-I levels (blood levels) increased significantly in the milk group . . . an increase of about 10% above baseline -- but was unchanged in the control group."
Why Did FDA Find The Genetically Engineered Bovine Growth Hormone Safe?
The FDA approved the genetically engineered bovine growth hormone after concluding that IGF-I was destroyed in the stomach. According to FDA, it is not possible that milk consumption would result in an increase of IGF-I in the human body. The evidence provided by this study should forever change the thinking of the scientific community.
The evidence provided by this study should forever change the milk-drinking habits of all Americans.
Is IGF-I In Milk A Danger?
By continuing to drink milk, one delivers the most powerful growth hormone in nature to his or her body (IGF-I). That hormone has been called the key factor in the growth of breast, prostate, and lung cancer.
At the very best, or worst, this powerful growth hormone instructs all cells to grow. This might be the reason that Americans are so overweight.
At the very worst, this hormone does not discriminate. When it finds an existing cancer, usually controlled by our immune systems, the message it delivers is: GROW!
A Miracle Of Nature
There are four thousand mammals in the animal kingdom and many millions of different hormones. Only one hormone is identical in structure between two species. That hormone is IGF-I. IGF-I is a protein hormone that survives digestion, and is an identical match between human and cow.
Eat their cheese, ice cream, yogurt, or milk and you take powerful growth hormones into your body. The increase in blood levels of IGF-I have been measured and confirmed by the dairy industry to be ten percent!
A suit has been filed (FDA citizen's petition - docket #99P-4613) to remove Monsanto's genetically engineered bovine growth hormone (rbGH) from the market, a hormone that poses a serious health risk to all humans.
Recent scientific evidence supports a conclusion that the consumption of milk from cows treated with recombinant bovine growth hormone (rbGH) poses a serious health risk to milk and dairy consumers.
The Food & Drug Administration (FDA) published a review of the controversy surrounding rbGH and, in doing so, concluded that the bovine growth hormone produced no metabolic effect in humans and is, therefore, no cause for concern. (1) That conclusion was based upon two principles.
First, FDA cited a pasteurization study in which they concluded that 90% of the bovine growth hormone was destroyed by heat treatment. In fact, that study revealed that only 19% of the bGH was destroyed, and that was accomplished by exposing milk to an exaggerated heat-treatment protocol.
During pasteurization, milk is traditionally treated for 15 seconds at 162°F. The study in question treated milk at 162°F. for 30 minutes, not 15 seconds. (2) Furthermore, FDA concluded that there was no basis for concern, assuming that protein hormones are digested in the stomach and gastrointestinal tract. (1)
FDA accepted the fact that the manufacturing process for Monsanto's version of rbGH did not produce an exact duplicate of the naturally occurring bGH, citing a study in which the N-terminus of rbGH was incorrectly transcribed as methionine.
In that citation, Jerome Moore revealed that the end amino acid would not produce a significant change in a protein, but warned that a different amino acid in the middle of the sequence of a protein chain could have significant consequences, quite often disastrous. (3)
Monsanto had actually discovered that a "freak" amino acid was created in the #144 position (of the 191 amino acid chain of rbGH) but withheld that information from FDA until after rbGH was approved. (4) Although Monsanto "fixed" this error, such an admission invalidated seven previous years of research in which rbGH with a "freak" amino acid was administered to laboratory animals.
In approving rbGH, FDA concluded that "wholesome milk" and genetically engineered milk were indistinguishable. In assessing the safety of the new milk, the Journal of the American Medical Association supported that incorrect conclusion. (5)
The abstract of FDA's Science paper and studies cited within that publication support the conclusion that levels of insulin-like growth factor-I (IGF-I) increase in milk from rbGH-treated cows. (1)
The bovine growth hormone and its genetically engineered version both contain 191 amino acids.
Human growth hormone also contains 191 amino acids. The gene sequence between the two species differs, however, by a factor of 35%. IGF-I in humans and cows contains 70 amino acids and the gene sequence is identical.1 IGF-I has been called a key factor in prostate cancer, (6) breast cancer, (7) and lung cancer. (8)
New evidence published in the Journal of the American Dietetic Association indicates that "serum IGF-I levels increased significantly in the milk group ... an increase of about 10% above baseline-but was unchanged in the control group."(9)
The conclusion that hormones contained in milk do not survive digestion has been incorrectly applied to the approval of rbGH. Science has ignored a general principle and universal wisdom applied to all mammals.
Milk is a hormonal delivery system. Mechanisms in milk insure that lactoferrins, immunoglobulins, and protein hormones do indeed survive digestive processes, and exert biological effects. Mankind might very well wake up in the 21st century and respond to the GOT MILK query with this conclusion supported by the most recent scientific observations: GOT CANCER.
