One of the biggest advantages of popcorn is that it's a whole grain. Whole grains help ward off long-term diseases such as heart disease, diabetes, and high blood pressure (via WebMD). The tasty treat also contains fiber, which can help with pregnancy constipation. A three-ounce serving contains an impressive 15 grams of fiber (via Healthline).
It also has polyphenols, an antioxidant that protects our cells against damage from free radicals and improves blood circulation. Polyphenols are even thought to reduce the risk of breast and prostate cancer. That means that even if you eat popcorn every day, it's not necessarily bad for you.
Popcorn is a low glycemic index food that will give you a burst of energy, according to WebMD. It also helps stabilize your blood sugar, which is necessary always but especially during pregnancy when your rapidly changing hormones are causing nausea as well as cravings.
In early pregnancy, popcorn can be a lifesaver when you can't hold much food down. It's plain enough to not upset an already upset stomach yet also has nutritional value. A sprinkle of salt on it can be soothing during morning sickness and help keep electrolytes up, too (via Pregnancy Food Checker).
