Between tofu and tempeh, miso and soy milk, and the ever-popular edamame, there'due south certainly no shortage of soy on the shelves of your local food store. Long touted by health-minded folks as a better-for-you, eco-friendly alternative to meat, soy is a favorite amid followers of increasingly mainstream found-based diets. Yet, do a quick Google search for "soy" and some of the commencement results include headlines like, "The Dangers of Soy" and "Is Soy Bad for Yous?"

So what's the bargain? Here'south what you should know about the pros and cons of eating soy.

The Benefits of Swapping Hot Dogs for Soy

1 of the biggest benefits of eating soy is that it tin supplant foods that may compromise your health, says University of Nutrition and Dietetics Spokesperson Vandana Sheth, RDN, CDE. "If we are talking near soy in its whole class such equally edamame, tofu and whole soy milk, then it is healthier than meat in the sense that soy provides an first-class source of protein, fiber, vitamins and minerals -- without the cholesterol and saturated fatty found in meat," she says.

It's the same rationale the Meatless Monday campaign uses to validate the claim that forgoing meat one mean solar day a week can lower your risk for cancer, cardiovascular disease, diabetes and obesity. You're probably (or, hopefully!) swapping out less healthful foods, such as cherry meat, in favor of establish-based foods. And while there's some prove that soy might slightly lower your take a chance of eye disease, the effects are minor -- but more than on that below.

But Is Soy Really a Superfood?

Aside from the thought that eating more soy might pb y'all to swallow less meat, there'due south not much evidence that soy itself produces wellness benefits. Claims that it lowers cholesterol, calms hot flashes, prevents breast and prostate cancer, aids weight loss and wards off osteoporosis are all based on preliminary research, inconclusive show or overstated claims according to a 2014 Harvard T.H. Chan School of Public Wellness report.

For example, while the American Heart Association used to abet eating soy as role of a "centre salubrious diet," they have since backed off that recommendation because the information did not back up such a merits, says Heather Patisaul, a developmental biologist at North Carolina State University who has studied the effects of eating soy. "For well-nigh people the benefits of soy on heart health are very small: a few cholesterol points just not much else," she notes.

In fact, an American Middle Clan review of 22 randomized trials found that eating fifty grams of soy a day merely lowers LDL (aka: bad) cholesterol by three percent. To put that in perspective, y'all'd accept to eat one-and-a-one-half pounds of tofu or drink eight, viii-ounce glasses of soy milk a day in club to eat 50 grams of soy. And that'due south a lot of tofu, even for the nigh defended of soy fanatics.

The Darker Side of Soy

Soy has a shadier side, too -- near notably regarding the issue it may have on your hormones. That'due south because soy contains isoflavones -- a blazon of phytoestrogren that mimics the effect of estrogen on the body. When you lot swallow lots of soy, it has the potential to disrupt estrogen-sensitive systems in your trunk, including the reproductive arrangement (which includes the brain, the pituitary gland and the reproductive organs), says Patisaul. There have even been cases where women have eaten so much soy (think: threescore grams a day for a calendar month) that they've temporarily shut down their menstrual cycle, Patisaul says. "The developing brain is too very sensitive to estrogen, every bit is the mammary gland and the eye," she notes.

It's the same argument you lot've likely heard against using plastic water bottles containing bisphenol A (BPA), except that soy is even more estrogenic than BPA, co-ordinate to a review of research on the pros and cons of phytoestrogens past Patisaul and her team. Beyond that, the NIH states that soy's possible role in breast cancer is "uncertain" and advises that, "women who have or who are at increased risk of developing chest cancer or other hormone-sensitive conditions (such every bit ovarian or uterine cancer) should be particularly careful nearly using soy and should discuss it with their wellness care providers."

"Because everybody is unlike, information technology is impossible to know what the 'right' amount of soy is, but people can certainly go overboard," says Patisaul. "For people wanting to reach a reasonably healthy poly peptide intake without experiencing possibly negative furnishings of soy, there is no need to have soy at every meal or to replace all foods [similar milk and cheese] with soy-based ones."

The Takeaway

So should you give up soy for expert? Non necessarily. Eating some soy tin can exist a healthy fashion to cut back on meat while withal making sure you lot're eating enough protein. But too much of a skilful thing has the potential to take its toll on your hormones and your health. "For healthy adults, I think about soy the way I recall about things like sugar, alcohol and caffeine," says Patisaul. "Moderation is cardinal."
