Can I eat it?

Yes. Plain firm calcium-set tofu can be part of a balanced diet with PCOS and supplies plant protein. Its calcium content depends on the coagulant and brand. This does not establish that tofu improves PCOS symptoms. If you have a soy allergy, choose another protein source.

How to include tofu in a balanced meal
