Fiber is a pregnant girl’s buddy. It keeps everything moving through the large intestine, and fights against all-too-common constipation. Also, fiber-rich foods are usually nutrient-dense, meaning they fill you up without adding tons of calories.
Shoot for 25 to 35 grams of fiber a day, and drink plenty of water to help the fiber move through your system. Veggies are a great choice. Go for crunchy (like carrots and celery) and cruciferous (like broccoli and cauliflower). Legumes and most fruits are also good sources. If veggies and beans make you gassy (and they probably will), 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.
