We make a nice cooked moong sprout sundal at home, I had it often. Amma always lightly steamed them, never fully raw. My doctor agreed cooking them is the safer choice, so that is what I followed.
I love sprouts for the protein but I always steam or boil them now instead of raw salad style. My doctor said that is the safe way in pregnancy. They go great in a warm chaat, healthy and filling.
My gynac told me sprouts are nutritious but raw sprouts can carry bacteria, so she advised cooking or steaming them lightly. Cooked sprouts are perfectly fine and good for protein. So enjoy them, just dont eat them raw during pregnancy.
