1 interaction related to soybeans
Edamame is whole young soybeans, and the soy protein and isoflavones bind levothyroxine in the gut and reduce its absorption, with measured drops of 16 percent at 20 grams of soy protein and over 35 percent at 40 grams. A one-cup serving of shelled edamame supplies roughly 18 grams of soy protein, enough to cause clinically meaningful interference if eaten close to the dose.
