Is soy flour bad for people with thyroid problems?

There is some concern that soy flour may be bad for people with thyroid problems, as it contains isoflavones which can interfere with thyroid function. However, there is no clear consensus on this and scientific studies have shown mixed results. Some studies have found that soy isoflavones can worsen symptoms of hypothyroidism, while others have found no effects or even some beneficial effects.

For people with thyroid conditions, it's always a good idea to talk to your doctor or dietician to discuss your specific case. They can help you determine if soy flour is right for you and provide guidance on how to include it as part of a healthy diet.
