The Best Vegetable to Help You Poop, According to Dietitians

This surprising veggie is a perfect addition to your diet when you need a little help to get things moving.

  • Do peas help with constipation? Their fiber, fluids and magnesium say yes.
  • Green peas pack insoluble fiber that adds bulk to stool and speeds up digestion.
  • With nearly 80% water, peas help soften stool and make bowel movements easier.

When it comes to easing the act of pooping, what you eat can make a big difference. Foods rich in fiber and fluids are especially helpful, since they’re two of the best-known ways to prevent and treat constipation.

We spoke with three registered dietitians, and they all recommend prioritizing fiber and fluids if you struggle with constipation. “Less than 5% of Americans get enough fiber, with most getting under 15 grams a day, when the minimum recommendations are 25 grams for women and 38 grams for men,” says Nichole Dandrea-Russert, M.S., RDN.

To help you get in more fiber, fluids and starch so you can poop regularly, we recommend eating more green peas. Read on to learn why these dietitians say peas are the best vegetable to help relieve constipation.

They're Rich in Insoluble Fiber

A 1-cup serving of cooked peas contains a total of 9 grams of fiber, or 32% of the Daily Value. Of these 9 grams of total fiber, about 70% is insoluble fiber. This type of fiber adds bulk to your stool to help speed up transit time through your digestive tract, so it’s especially helpful for constipation.

The remaining 30% of peas' fiber is soluble fiber, which helps attract water into your gastrointestinal tract during digestion. This type of fiber is more helpful for relieving diarrhea, but it can also help reduce your risk of heart disease. Both kinds of fiber are essential for overall digestive health, says Dandrea-Russert, and most fiber-containing foods have a combination of both.

They Have High Fluid Content

Getting in enough fluids throughout the day is key to preventing and treating constipation, says Emily Maus, RD. “Hydration is important to keep stool a softer consistency for easier passing,” she explains. Because soluble fiber attracts water, the combination of the two is needed for more comfortable bowel movements.

When you think of hydration, you may think of lugging around a big water bottle, but most fruits and veggies have a high fluid content that can contribute to your total fluid intake.

Kaytee Hadley, M.S., RDN, highlights green peas as a high-fiber and high-fluid veggie because they’re made up of almost 80% water.

They're a Source of Magnesium

Many people have heard that fiber and fluid are good for relieving constipation, but did you know that magnesium—a mineral found in green peas—may also help?

“One study looked at the diets and bowel habits of 9,519 adults and found that dietary magnesium was inversely associated with constipation. Those with higher dietary magnesium reported less constipation compared to those who consumed less magnesium through their diet,” says Dandrea-Russert. Magnesium may have a laxative effect by pulling water from your body into your stool, improving stool frequency and consistency.

Interestingly, many Americans don’t meet the recommended intakes of magnesium. Eating foods like green peas can help you consume more magnesium for overall health and potentially even constipation relief. Each cup of cooked green peas contains an impressive 15% of the DV for magnesium, according to the USDA.

You may be used to having frozen or canned peas as a side dish, and this Quinoa with Peas & Lemon recipe kicks things up a notch.
