Quick Answer

According to ACOG and the Journal of Nutrition, tofu is generally considered safe during pregnancy. Soy phytoestrogens in dietary amounts do not have clinically significant estrogenic effects in humans per published research. Excellent protein source โ€” 21g protein and 66% DV calcium per half-block (USDA data).

Key Takeaway: Tofu and soy foods are considered safe during pregnancy. Phytoestrogen concerns are not supported by clinical evidence at dietary intake levels. Tofu provides 10g protein per half cup, calcium (when calcium-set), and iron. A valuable protein source for vegetarian pregnancies.
