soy protein raises IGF-1 levels in humans
'Circulating levels of insulin-like growth factor-1 (IGF-1) and
insulin-like growth factor-binding protein-3 (IGFBP-3) have
each been associated with premenopausal breast cancer risks.
We analyzed data from a cross-sectional study of 261
premenopausal Japanese women aged 20-54 yr with adequate
nutritional status to evaluate the relationships between
concentrations of IGF-1 and IGFBP-3 in serum and dietary
intakes of soy, fats and other nutrients. Diet was assessed by
a semiquantitative food frequency questionnaire. There was
no significant correlation between soy product as well as soy
isoflavone intake and serum IGF-1 or IGFBP-3 levels after
controlling for age, total energy, percent body fat, and
education level. Total fat intake was significantly inversely
correlated with serum IGFBP-3 level (r = -0.13, P = 0.04).
The correlations of saturated and monounsaturated fats with
serum IGFBP-3 were of borderline significance (r = -0.12,
P = 0.06 and r = -0.11, P = 0.07, respectively).

'Frequent consumption (more than once a day) of soy milk was
associated with 70 per cent reduction of the risk of prostate cancer
(relative risk = 0.3, 95 percent confidence interval 0.1-1.0, p-value
for linear trend = 0.03). The association was upheld when extensive
adjustments were performed. CONCLUSIONS: Our study suggests
that men with high consumption of soy milk are at reduced risk of
prostate cancer. Possible associations between soy bean products,
isoflavones and prostate cancer risk should be further investigated.

MILK CONSUMPTION IS KEY
Using data from a large, long-term study of more than 1,000 nurses
who record their diets carefully and who are then watched for
changes in health, Holmes' team also found that those who drank
the most milk had higher levels of IGF-1.
IGF-1 is important to the growth and function of many organs, but
higher levels have been associated with an increased risk of prostate,
colon, lung and breast cancer.
"We concluded that greater milk consumption was associated with
higher levels of IGF-1," said Holmes. "This association raises the
possibility that diet could increase cancer risk by increasing levels
of IGF-1 in the blood stream.
