Women Could Be at Risk From Soy
By Judi Sheppard Missett
CEO of Jazzercise, Inc.
Soy created a tremendous buzz in
health circles when the U.S. Food and
Drug Administration approved special
labeling for foods containing 6.25
grams of soy protein per serving. Such
foods can carry the following health
claim: "Diets low in saturated fat and
cholesterol that include 25 grams of
soy protein per day may reduce the
risk of heart disease."
The FDA's decision to allow this claim
was influenced by studies like the one
conducted at Wake Forest University
Baptist Medical Center in
Winston-Salem, N.C., which found that
people who ate low-fat diets high in
soy foods lowered their LDL, or "bad"
cholesterol, by 10 percent. In addition
to decreasing the risk of heart
disease, soy also has been credited
with building strong bones and
preserving lean body mass.
But soy may not be the wonder food
early reports have implied. New
concerns have surfaced regarding soy
and breast cancer. Plant-based
estrogens found in soy protein, called
isoflavones, have been found to
stimulate breast cell proliferation. As
some types of breast cancer rely on
estrogen to grow, it is possible that a
diet high in soy protein may actually
speed the growth of cancerous cells.
Additional research is warranted, but
women who have breast cancer or are
at high risk are advised not to
consume large quantities of soy. In
fact, if soy is not currently part of their
diets, experts suggest, leave it out. For
women who eat soy regularly,
moderation is the key.
Many experts believe that cancer
survivors are safe consuming 2 to 3
ounces of soy-based foods a day. One
to three servings of soy are
appropriate for women who are not at
high risk for breast cancer.
Of course, diet is only half of the health
equation. To lower your risk of
disease, you should also:
Refrain from smoking
Consume alcohol and caffeine in
moderation
Maintain a healthy weight
Exercise regularly
A well-rounded fitness program
includes both aerobic exercise and
strength training. Guidelines set forth
by the American College of Sports
Medicine recommend three to five
aerobic workouts and two strength
training sessions per week.
