Fiber is a pregnant girl’s buddy. Why? It keeps everything moving through the large intestine and fights against that all-too-common pregnancy symptom, constipation. Plus, fiber-rich foods are usually nutrient-dense, meaning they fill you up without adding tons of calories. (You really only need an extra 350 extra calories in the second trimester and about 450 extra calories in the third trimester, according to Pooja Shah, MD, regional medical director for Banner Medical Group AZ East and a practicing ob-gyn.)

Shoot for 25 to 30 grams of fiber a day, the American Pregnancy Association says, and drink plenty of water to help the fiber move through your system.

So which fiber-rich foods can help you get to your daily goal? Fruits, veggies and beans are all excellent sources, but if those make you gassy, try whole grain breads and cereals. These also contain lots of fiber but may be easier to digest. Avoid white foods like pasta, rice and non-whole grain bread. Check out more high-fiber options:
