IF BREASTFEEDING WORKS, DOES COW'S MILK DELIVER POWERFUL
HORMONES TO ALL HUMANS?
A DOCTOR WHO MAKES "FREE" HOUSECALLS
Welcome to the home page of Alan Greene, M.D., a
pediatrician who takes questions and in answering them
offers detailed advice dispensed with caring bedside manner.

I asked Dr. Greene a question which he posted to his
"I met with top scientists at the FDA in Rockville,
Maryland, discussing among other things, breastfeeding. It
was their collective opinion that breastfeeding offered
psychological nurturing benefits, but nothing more. Their
logic was that all proteins are broken down by strong
digestive enzymes. What do you think?"
DR. GREENE WROTE:
"Many studies comparing the frequency of illness between
breast and formula-fed infants have demonstrated fewer
illnesses and less severe illnesses in breast-fed infants
(Garza et al, Special Properties of Human Milk, Clinics of
Perinatology, 14: 11-32, 1987).
"Mounting evidence shows a striking reduction in the
incidence and seriousness of gastrointestinal infections,
respiratory infections, and ear infections in breast-fed
babies (Duncan et al, Exclusive Breast Feeding for at Least
Four Months Protects Against Otiis Media, Pediatrics, 91:
"If the immunoglobulins are rendered useless by digestion,
how could this be?
"All types of immunoglobulins are found in human milk. The
highest concentration is found in colostrum, the pre-milk
which is only available from the breast the first three to
five days of the baby's life.
"Lactoferrin is an iron-binding protein that is found in
human milk, but not available in formulas. It limits the
availability of iron to bacteria in the intestines, and
alters which healthy bacteria will thrive in the gut.
"Human breast milk contains lysosomes (a potent digestive
ingredient) at a level thirty times higher than in any
formula. It has a strong influence on the type of bacteria
which inhabit the intestinal tract.
"Human breast milk specifically encourages the growth of
Lactobacillaceae, helpful bacteria which can inhibit many of
the disease-causing gram-negative bacteria and parasites.
In fact, there is a striking difference between the bacteria
found in the guts of breast and formula-fed infants.
"The cows' milk protein used in many formulas is a foreign
protein. When babies are exposed to non-human milk, they
actually develop antibodies to the foreign protein.
Research has shown that without exception the important food
allergens found in milk and soybean formulas are stable to
digestion in the stomach for as long as 60 minutes (as
compared to human milk protein which is digested in the
stomach within 15 minutes). Thus, the foreign proteins pass
through the stomach and reach the intestines intact, where
they gain access and can produce sensitization.
"It becomes clearer year by year, that human milk is
precisely designed for human babies. There may well be
other important micro-nutrients or factors that we don't
even have instruments to measure yet. Not many decades ago,
immunoglobulins weren't even imagined."
THANK YOU, DR. GREENE!
What are the implications? Clearly, proteins in milk
survive digestion. Nursing mothers believe this. Their
pediatricians certainly believe this. The only ones who do
not believe this are the FDA scientists. If proteins in
human milk survive digestion, then proteins in cow milk
survive digestion. If IGF-I is the most powerful growth
hormone in the human body, and if cow IGF-I is identical to
human IGF-I, then every time we drink a glass of milk or eat
a slice of cheese we take hormones into our body. Indeed,
protein hormones do survive digestive processes. Milk is a
hormonal delivery system.
