Enjoy Soy:
Dr.Debunks Scaremonger Stories, Says Soy Beneficial For People And The Planet
If you avoid eating soy-based foods, including tofu, tempeh, edamame, veggie
burgers, and soy milk because you've heard reports claiming that soy products
are responsible for everything from "man-boobs" and cancer to deforestation
you might be interested in the recent Guardian article urging people to ignore
all the scaremonger stories and eat more soy.
According to the commentary, most anti-soy stories can be traced back to Weston
A Price Foundation (WAPF), a group that claims that saturated animal fat is
essential for good health, animal fat intake and high cholesterol levels aren't
connected to heart disease or cancer, vegetarians have lower life expectancy
than meat-eaters, and other pro-meat propaganda that contradicts leading health
experts, not to mention basic common sense. One of WAPF's more ardent
supporters, Dr. Stephen Byrnes, openly boasted about his high animal fat diet
and robust health—until he died of a stroke at 42.
Much of what the WAPF says is anecdotal, untrue, or based on scientifically
flawed animal experiments, points out Dr. Justine Butler, a health campaigner
for the Vegetarian & Vegan Foundation. There is no scientific evidence showing
that soy is harmful to humans, yet some people continue to perpetuate
groundless scare stories about soy. When Dr. Butler was interviewed for
BBC Radio London, for example, the presenter asked her if soy foods were safe,
then "fell about laughing saying he didn't want to grow man-boobs."
Now, I'm just guessing here, but I bet he wasn't equally concerned about
developing gynecomastia—the clinical term for man-boobs or "moobs"—from
eating meat and dairy products, even though many physicians believe that the
conditions is caused by the estrogen-mimicking chemicals in these foods.
(Factory-farmed animals are fed growth-promoting hormones that accumulate in
fat tissue and are taken up by the estrogen receptor sites in the body.
Hormone-treated cow’s milk, for instance, contains high levels of
Insulin Growth Factor (IGF-1), which studies show can cause gynecomastia.)
In fact, many of the people who have asked me about soy in the past think
nothing of chowing down on hamburgers and cheese pizza. Soy may not be a
"miracle food," because there really is no such thing, but unlike meat, eggs,
and dairy products, soy is cholesterol-free, low in saturated fat, and has
cardiovascular benefits.
Researchers with the Cancer Center at Children’s Hospital Oakland Research
Institute have found evidence suggesting that eating soy can help ward off
colon cancer, and soy is also known to prevent prostate and breast cancer.
Research shows that women who eat soy, especially early in life, are 30 percent
less likely to develop breast cancer, compared with women who eat little or no
soy products. For women who’ve already been diagnosed with breast cancer,
eating soy may actually help reduce their risk of a recurrence.
Research also shows that soy consumption can help prevent strokes, that
menopausal women who eat soy may have fewer hot flashes, and that soy
consumption can protect against osteoporosis. A study from Clinical and
Experimental Allergy suggests that the antioxidants in soy may also benefit
asthma sufferers.
And for those who've heard that soy production destroys the Amazonian
rain forest, Dr. Butler rightfully points out that the problem is not people
eating soy; it's that 80% of the world's soy is fed to farmed animals so that
people can eat meat and dairy products.
So, while there's no need to go overboard by drinking soy-infused water and
the like, go ahead and enjoy soy. It's not only healthy and humane, it's
versatile and delicious. As Dr. Butler concludes, both the rain forests and
our health will benefit tremendously if more people switch from animal-based
foods to a varied plant-based diet, including soy foods.
