Soy has come under some scrutiny lately, largely due to a recent review of studies conducted by the American Heart Association on the protein source's efficacy in protecting or improving cardiovascular health. The results of the study found no conclusive link between soy and such health benefits.

Additional studies also put soy in the hot seat. For women, soy was revealed to be almost worthless in alleviating menopause symptoms. Then, in a different study, researchers allegedly discovered that a diet rich in soy may actually lead to thyroid problems.

It seems as though the official verdict is still not in on soy, as there is still plenty of evidence to the contrary of that which was just mentioned.

Feel free to weigh in with your own opinions and/or links to studies and research on the health benefits (or lack thereof) of soy.
