“We found a positive association between intake of skim milk
and acne. This finding suggests that skim milk contains hormonal
constituents, or factors that influence endogenous hormones, in
sufficient quantities to have biological effects in consumers.”


Notmilkman’s Comment:

At last! Epidemiological data to support scientific research:

Acne occurs when steroids (androgens) stimulate the sebaceous glands
within the skin’s hair follicles. These glands then secrete an oily
substance called sebum. When sebum, bacteria and dead skin cells
build up on skin, pores become blocked, creating a zit.

“As pointed out by Dr. Jerome Fisher, ‘About 80 percent of cows that
are giving milk are pregnant and are throwing off hormones continuously.
Progesterone breaks down into androgens, which have been implicated
as a factor in the development of acne…Dr. Fisher observed that his
teenage acne patients improved as soon as the milk drinking stopped.”

Pediatrics, Johns Hopkins University School of Medicine)

“Acne usually begins at puberty, when an increase in androgens causes
an increase in the size and activity of pilosebaceous glands…if a food
is suspected, it should be omitted for several weeks and then eaten
in substantial quantities to determine if acne worsens.”

“Acne is an end-organ hyper-response to androgens…These data show
that sebaceous glands are stimulated by androgens to varying degrees
and support the theory of an end-organ response in acne.”

“Acne vulgaris is a self-limiting skin disorder seen primarily in
adolescents, whose etiology appears to be multifactorial. The
immunologic response involves both humoral and cell-mediated
pathways. Further research should clarify the role of complement, cytotoxins,
and neutrophils in this acne-forming response.”

“Hormones found in cow’s milk include: Estradiol, Estriol,
Progesterone, Testosterone, 17-Ketosteroids, Corticosterone,
Vitamin D, insulin-like growth factor, growth hormone,
prolactin, oxytocin…”

Journal of Endocrine Reviews, 14(6) 1992

“We studied the effects of growth hormone (GH) and insulin-like
growth factors (IGFs), alone and with androgen, on sebaceous
epithelial cell growth…IGF-I was the most potent stimulus of
DNA synthesis. These data are consistent with the concept that
increases in GH and IGF production contribute in complementary
ways to the increase in sebum production during puberty.”
