Of course you can eat bhutta, but don't eat it from those unhygienic roadside stalls. Make it fresh at home, boil it or roast it properly, and put some lemon on it. Simple and safe.
When I was staying at my parents' place, my mother used to boil fresh sweet corn for me at home. It is very safe and good for digestion, just avoid the raw or half-cooked ones from outside. Homemade is best.
Bhutta is generally very safe and has good fiber, but please ensure it is made hygienically to avoid any stomach infection, which can complicate things. Avoid outside street vendors if you can, and always check with your doctor if you have gestational diabetes as corn is high in carbs.
Yes, you can definitely have bhutta! Just make sure it is freshly roasted and hot. Eating healthy, high-fiber food during my pregnancy really helped with digestion and made my recovery after the C-section much smoother.
