  • A soybean - a rather simple legume originating from Eastern Asia thousands of years ago,

  • has, in one form or another, beaned its way into the pantries of almost every household.

  • Soybeans are nutritionally one of the best plant crops discovered, containing high amounts

  • of calcium, potassium, fiber, vitamin c, folic acid, and healthy polyunsaturated fats.

  • But these legumes are best known for its high protein content, where at 36 grams of protein

  • in a serving, beats out all other plants.

  • It's even been called a superfood, with links to reducing heart disease risk, prostate cancer,

  • osteoporosis, and even Alzheimer's.

  • Soy is now popular as an alternative for common food products such as burgers, pasta, and

  • milk.

  • But it wasn't always popular.

  • It made its US debut in the 1700s and was fed exclusively to animals.

  • Not until the 1920s did we started eating it ourselves.

  • Today, soy is the second most popular crop in the US, surpassing other big names such

  • as wheat, cotton, and rice.

  • It was all fine and dandy for this little super food up until new studies began making

  • some really serious claims.

  • Claims that made soy seem completely evil.

  • People got scared, pitchforks went up, and soy's popularity is in disarray.

  • But what exactly are the studies saying?

  • Should we really fear a little legume?

  • According to the studies, a reason to avoid soy is due to soy's high concentration of

  • isoflavones, which in high doses, can cause the development of cancerous cells.

  • Quite a serious problem if true, however, other studies showed that isoflavones had

  • no correlation to cancer cells at all, but in fact, it might prevent cancer cell development.

  • And women, it might even reduce menopausal symptoms as well.

  • But men, be careful since a study showed lower testosterone levels in mice after ingesting

  • 20 milligrams per kilogram of these evil isoflavones!

  • Wait!

  • Not soy fast.

  • How much isoflavone is that exactly?

  • In human levels, that's equivalent to an unreal 57 cups of soymilk per day!

  • A more practical study found zero testosterone changes when subjects consumed the equivalent

  • of 3 cups of soymilk per day.

  • But there's more claims against soy.

  • In another case, claims were made that soy can interfere with thyroid function because

  • soy contains goitrogens, a substance that leeches iodine away from thyroid hormones.

  • Not good at all.

  • But again, studies show that even subjects with low iodine levels showed zero changes

  • in their thyroid from eating soy.

  • In fact, the American Thyroid Association reviewed 14 studies about this problem and

  • concluded that there is "little evidence" of soy negatively impacting thyroid function.

  • But perhaps the biggest soy controversy is genetic modification.

  • A staggering 93% of all soybeans in the US and 79% in the WORLD are genetically modified.

  • Although genetic modification, aka GMO, is a colossal topic that can't be covered in

  • this video alone, it can be said that, as far as research goes, there is no sign that

  • GMO soy will cause harmful effects to human health.

  • This stance, however, can change in the future if the research shows otherwise.

  • Of course, we also don't know how the substances, such as pesticides, used on GMO crops might

  • affect our health.

  • Now with all these studies analyzed, what's the verdict?

  • Should we still eat soy?

  • Indications are that moderate consumption should be okay.

  • There's no strong evidence showing that soy will cause cancer, lower testosterone, or

  • mess up your thyroid.

  • Also, if you cook or ferment the beans, a lot of these supposedly dangerous toxins are

  • actually eliminated in the process.

  • Oh, and for anti-GMO peeps, stick with the organic stuff.

  • Whether you're going to eat soy or not from now on, it won't change the fact that this

  • small bean is jam packed with nutrients.

  • The title of "super food" doesn't seem too far-fetched.

  • What are your thoughts on soy?

  • Curious about any other health and nutrition topics?
