Negative Health Effects of Soy

Negative Health Effects of Soy

In the early 1990′s, soy and soy products exploded onto the supermarket scene with promises of bountiful health benefits. This “new miracle food,” soy, was supposed to lower cholesterol, take the heat out of hot flashes, protect against breast and prostate cancer and offer a filling alternative to earth-loving vegetarians.

The problem with these claims? Many of them are false.

While some types of soy do have health benefits, it’s important to be aware of some of the potential negative effects as well.

For you vegetarians out there staring at the screen in open-mouthed shock, fear not. There are plenty of other healthy vegetarian alternatives, which I will discuss later in this article. What was once considered a minor industrial crop back in 1913 now covers over 72 million acres of farmland. But first, let’s examine the dangers and side effects of soy protein isolate and GMO foods.

Soy Protein Isolate — What is It, and How is it Getting in My Food?

The Soyfoods Association of America has a soy protein “fact sheet” defining soy protein isolate as the following:

“Soy protein isolate is a dry powder food ingredient that has been separated or isolated from the other components of the soybean, making it 90 to 95 percent protein and nearly carbohydrate and fat-free.”

Soy protein isolate can be found in protein bars, meal replacement shakes, bottled fruit drinks, soups and sauces, meat analogs, baked goods, breakfast cereals and some dietary supplements.

Bodybuilders beware: many weight gainer powders, bars and shakes contain this dangerous ingredient and it can cause troubling side effects such as diminished libido and erectile dysfunction — and this is just the start. You’ll find out more about these disturbing health effects later on in this article.

Kind of misleading to me. and with shock factors.
It is up to each of us to check everything out for ourselves...this technological age of computers helps, but we still have to double check.

Soy is the unspecifically mentioned cheap, chemically derived GMO oil used for making most already prepared and prepackaged foods Most people who don't eat raw foods, and/or prepare their own knowingly, are having gallons of GMO soy,even if they despise tofu.

The unrelated anatomy of the rats and mice tortured in labs is pseudo science and gives no proof of it's effects on humans, it's just sad and pathetic .

The illusion given here, maybe inadvertently is that block of tofu (which most brands i seen are Non GMO,) is the cause of all our problems.It is processed so it shouldn't be a staple. Neither should meat.You'll find more clogged arteries and heart attacks leading to death,depression, hostility and illness there -

Ayurveda 5,000 BCE was wise & kind enough to tell us whats good for our bodies, Modern science hasn't gotten past page1 since.

In America corporations are dumping GMO corn and soy in all the food they are able,what is it 80 or 90 %.of prepackaged food now -You think that could be a part of it? The same scientists who made manipulated chemicals into edibles,do animal tests to tell us their bad.Their whole way of reasoning seems pretty bad.

There's a reason Monsanto went for the cheap corn & soy oils first,and that's a problem.People can cut out organic tofu but it doesn't seem much of a favor when GMO oils are in everything else.

Eating raw foods and preparing for ourselves is the way to go.Pretty much always has been until the

From Wiki:

Phyllis Entis, a microbiologist and food safety expert, highlighted as an example of websites "likely to mislead consumers by offering one-sided, incomplete, inaccurate, or misleading information."[13] In 2005, 2006 and 2011 the U.S. Food and Drug Administration warned Mercola and his company to stop making illegal claims regarding his products' ability to detect, prevent and treat disease.[6] The medical watchdog site Quackwatch has criticized Mercola for making "unsubstantiated claims and clash with those of leading medical and public health organizations [and making] many unsubstantiated recommendations for dietary supplements.".[6]

Traditional soy such as tofu is fine, it is these modern over processed "mock" meat products and soy protein isolate that is nasty. Even tofu and soy milk should not be over consumed!

OK, if you're going to aim at writing a scientific-sounding article try eliminating alarming language ("this will shock you!") and exclamation marks and I might even take you seriously. As it is, this drivel has little credibility without actual citing studies. SHAME on care2 for allowing this.

Ok, I am not even going to touch the soy issue...however, I just HAD to comment on the fact that he just posted an article (last month?) about the dangers of eating beans and grains and now suggests them as great substitutes for soy... ???

Too contradictory for me...

So for the most part, its not soy that is unhealthy and a problem, its GMO and pesticides. So buy organic soy products is all. Also, sure there are studies that suggest that soy can have negative effects on health but there are just as many studies that say the opposite, perhaps more. All foods, but especially animal products like dairy, eggs and meat, have negative health side effects much worse than anything soy may cause.

Almond milk tastes better than soy milk.
