Myth #1: Soy Causes Cancer. Because soy isaflavones have a similar chemical structure to human estrogen, people battling hormone-related cancers were encouraged to avoid soy. But over 2000 peer reviewed studies have confirmed that soy can actually reduce the side effects of cancer and reduce the likelihood of it returning.
Myth #2: Soy Inhibits Thyroid Function. In the past, research suggested soy consumption could have a negative effect on thyroid function. However, in those studies, what was more commonly identified was the deficiency in iodine levels combined with the soy intake.
In summary, more iodine (and not less soy) is what is needed to maintain thyroid function.
Myth #3: Soy Does Not Help With Heart Health. In 2017, the FDA reversed their position on soy and heart health, thereby declaring that soy did not help with heart health. In fact, an analysis published in the Journal of the American Heart Association concluded that soy is heart-healthy and that it lowers LDL “bad” cholesterol that can increase the risk for heart disease.
