Blood sugar can be better managed with the kind of carbohydrates that are consumed. Carbohydrates coming from whole grain cereals and millets like whole wheat products, brown rice, buckwheat, whole oats, barley, bajra, jowar, amaranth help in better glucose control. Combine these carbs either with protein or healthy fats. Also, it is advised to eat small amounts of carbs at a time rather than large amounts at a time. 

Protein rich foods like beans, lentils, unsweetened milk and milk products, cooked eggs and lean meat along with the healthy carbs help in the better management of sugar levels. Try to include protein in every meal, both plant and animal proteins as requirements increase for fetal growth.
