Soy May Reduce Risk of Colorectal
Cancer
A new study published in the American Journal of Clinical
Nutrition explores how soyfood consumption may
lower the risk of colorectal cancer, or cancer of the
colon or rectum, in postmenopausal women. According to the
National Cancer Institute, an estimated 71,560 American women
were diagnosed with the fourth most common cancer.
Vanderbilt University School of Medicine researchers found
that women who consumed at least 10 grams of soy protein daily
were one-third less likely to develop colorectal cancer in
comparison to women who consumed little soy. This is the
amount of soy protein available in approximately one serving
of tofu (1/2 cup), roasted soy nuts (1/4 cup),
edamame (1/2 cup) or soy breakfast patties (2
patties).
The study observed soy intake in 68,412 women between the ages
of 40 and 70, all free of cancer and diabetes prior to the
initial screening. Researchers identified 321 colorectal
cancer cases after participants were monitored for an average
of 6.4 years. After adjusting for confounding factors, total soy
food intake was inversely associated with colorectal
cancer risk among postmenopausal women.
"Research this comprehensive demonstrates how important it is
for baby boomer and older women to add soy into their
daily diet," said Lisa Kelly, RD, MPH, for the United
Soybean Board. "Furthermore, the study's recommended serving
is a simple and affordable nutritional step towards
everyday wellness."
Evidence shows soy can play an important role in a
healthy diet for a variety of reasons. It is a source of
high-quality protein, and contains relatively little saturated
fat as well as zero grams of trans fat. Soy protein also
directly lowers blood cholesterol levels. And, for
postmenopausal women in particular, the largest and longest
trial published to date reported that the phytoestrogens in
soy reduced hot flashes by 50 percent. A range of products -
from soymilk to soy burgers to soy protein bars
- can help deliver soy's benefits with convenience.
