I actually ate tapioca chips twice during my pregnancy because of cravings and it was totally fine! But my doctor told me to stay away from raw or boiled cassava root because if it's not cleaned and cooked properly, it can have toxic stuff. Better stick to safe, well-cooked options.
In my experience, it's best to eat cassava only occasionally and in very small quantities. Since it's a heavy root, it can sometimes cause gas or bloating which gets super uncomfortable. If you really want to eat it, boil it thoroughly and see how your stomach feels.
Honestly, you should be very careful with cassava. Because of my thyroid during pregnancy, I learned that raw or poorly cooked cassava can interfere with thyroid function. Always make sure it is cooked completely, and keep getting your thyroid levels checked regularly by your doctor.
Mera advice toh yehi hai that ask your elders. My mother-in-law completely banned me from eating cassava or any unusual roots, saying they are too heavy and hard to digest during pregnancy. We stuck to simple potato, sweet potato, and ghar ka khana.
I would suggest avoiding heavy foods like cassava as they can cause constipation, which is a nightmare especially if you end up having a C-section later. After my surgery, doctor strictly asked me to avoid gassy foods to help my stitches heal properly, so better to be safe now.
