Frequently Asked Questions

Are beans good for gestational diabetes?

Yes! Beans are excellent for GD. They're high in fiber and protein, which slows sugar absorption. The glycemic index is low (around 30-40). A 1/2 cup serving provides 15-20g carbs but the fiber content makes the blood sugar impact gentler than other carbs.

Can I eat hummus with gestational diabetes?

Yes! Hummus is a GD-friendly food. It's made from chickpeas (high fiber, moderate carbs) and tahini (healthy fat). About 2-3 tablespoons of hummus has 5-8g carbs. Pair with vegetables instead of pita bread for a low-carb snack.
