7. Soy and its derivatives
Soy foods are rich in nutrients including vitamin B, fiber, potassium, magnesium, and high-quality protein. It’s considered a complete protein because it contains all 9 essential amino acids that the body cannot make. But if you’ve changed your diet recently due to thyroid problems, beware: soy might interfere with hormone medication used to treat hypothyroidism in female patients. Although studies are not conclusive, it’s worth monitoring carefully.
