Is too much soy on a vegan diet bad for you?

Im on a vegan diet. I love soy! I heard eating lots of tofu and soy is bad for you and can lead to weight gain. I eat 3 smart dogs a day sometimes! I have switched from soy milk to almond to help. I do eat a ton of veggies and fruit, so I get plenty of that!



Thanks for the advice.Is too much soy on a vegan diet bad for you?
That study small scale, preliminary study that Dr. Jorge Chavarro from the Harvard School of Public Health claiming “soy products may lower sperm count” do not tell the whole story. It was a small scale, preliminary study was based on recollected intake of soy and not on
specific diets containing soy. The research did not find a negative relationship between soy and sperm mobility or sperm quality, which are both key factors to fertility. The study also did not determine directly what other foods, medications, supplements, existing medical conditions, sexual activities or environmental factors may have directly affected the drop in sperm count.
According to New Scientist in http://www.newscientist.com/article/dn12… , Chavarro admits that many East Asian men consume much more soy than the participants in his trial and do not develop fertility problems. "He speculates that his study found a link between soy and low sperm count because many of the participants were overweight or obese. Men with high levels of body fat produce more oestrogen than their slim counterparts.” "They already have a lot of background estrogen," says Chavarro. He found that “soyfood and soy isoflavone intakes were unrelated to total sperm count, ejaculate volume, sperm motility, or sperm morphology” which are the important measures of sperm quality and male fertility.

Generations of Asians, not just the Japanese, have regularly consumed soy without fertility disorders, and Asian countries have produced very healthy, highly functioning children for centuries.
And previous rodent studies have suggested that high intake of soya products can reduce male fertility. This has led scientists to wonder how isoflavones might influence men's reproductive function, which is highly sensitive to hormones. http://www.newscientist.com/article/dn75…
The rest of the garbage that Daisy listed are either studies that were conducted on animals like mice or rabbit or were small-scale, preliminary, cross-sectional, uncontrolled studies, or short-term studies, not randomized controlled studies. They mean nothing overall. They do not tell the whole story and are based on? big, noticeable limitations. These study also did not determine? directly what other foods, medications, supplements, existing medical conditions, activities or environmental factors may have directly affected the the test subjects. Humans metabolize soy a lot differently than animals do.

I think you'll find some disagreement among medical types about soy. Health agencies in several countries have issued warnings about soy consumption:



"While the U.S. has stayed out of the fray over soy, other countries have taken action to limit the possible dangers of soy. The French Center for Cancer Research put out a warning saying that soy products -- in any amount -- should not be eaten by children under 3 years of age or women who have breast cancer or are at risk of the disease. The Israeli Health Ministry has also issued a public warning on soy, suggesting that soy consumption be limited in young children and avoided if possible in infants. In Germany, the Federal Institute for Risk Assessment is doing a study of isoflavone supplements, and has reported that there's a lack of evidence to confirm the safety of such supplements, and some evidence to suggest that there may be health risks..."

There are documented cases of soy causing low sperm count in men who eat a lot of it. It's also been tied to early puberty in girls and thyroid disease:

If you don't have a thyroid condition or a family history, some soy probably won't hurt you. But too much of anything isn't good and it sounds like you're eat a lot of soy. (A thyroid condition can lead to weight gain)



The Japanese eat soy, but they eat mostly fermented soy. But tofu and most soy products in the US are not fermented.



Considering the potential problems with a lot of soy in the diet, perhaps you should cut back some?Is too much soy on a vegan diet bad for you?
25 grams of soy protein a day is beneficial in protecting against heart disease. Asian countries, especially Japan, eat a lot of soy every day. And they're the healthiest people in the world.

Smart dogs are processed junk. Eating any kind of processed food 3 times a day is extremely unhealthy.Is too much soy on a vegan diet bad for you?
Er yeah...soya three times a day is probably going to be bad for you. It is an important and useful addition to a vegetarian diet but anything in excess is not great...also these Smart Dog things look pretty processed and you want to try and focus on less processed stuff if you are vegan.
Everything in moderation. 'Smart dogs' probably aren't as good for you as tofu, as it is more processed, has more ingredients, and probably contains gmo soy, which I have read is more allergenic than non-gmo. Not to mention soy protein isolate is often processed with hexane, something nobody should be consuming.



I personally keep my soy consumption narrowed down to tofu, tempeh, and soy milk. If money wasn't a concern, and health was my number 1 goal, I'd probably get all of my soy from tempeh.
