5 Ways Pumpkin Benefits Your Gut Health
When most people think of pumpkins , jack-o'-lanterns and pumpkin pie may be the first things that come to mind, but this isn't all they're good for. Every part of the pumpkin, from its flesh to its seeds, can be eaten in some way. And these gourds are loaded with gut-healthy nutrients like iron, fiber, potassium, beta-carotene, and magnesium.
Below are five ways that eating pumpkin regularly can help improve gut health.
1. Pumpkin Supports Bowel Regularity
Pumpkin is an excellent source of fiber , and its flesh is particularly rich in the soluble kind, which is helpful for keeping bowel movements regular.
Soluble fiber is unique in that it can improve both constipation and diarrhea, making stool more comfortable to pass, says Danielle Gaffen, RDN , the San Diego-based founder of Eat Well Crohn's Colitis, through which she provides personalized nutrition counseling for people living with inflammatory bowel disease (IBD) and other digestive conditions. Pumpkin "absorbs water and forms a gellike consistency in the digestive tract, which can help normalize stool consistency," Gaffen says.
To improve diarrhea, soluble fiber slows gastrointestinal (GI) transit time, meaning food moves through the GI tract more slowly, absorbing water in the process. On the flip side, soluble fiber serves as a bulking agent, which can help relieve constipation because it makes stool easier to pass.
If you're having trouble going to the bathroom, you may want to think twice before throwing away the pumpkin seeds. Pumpkin seeds are one of the richest sources of magnesium , a mineral that improves constipation. Research suggests that people who consume more magnesium through diet are less likely to experience chronic constipation .
In fact, magnesium's ability to promote bowel regularity is so well recognized that high doses of the mineral are included in many over-the-counter laxatives. Magnesium supplements have an osmotic effect, drawing water into the bowel to increase stool volume and stimulate motility.
If your dietary intake of magnesium falls short, you may be more likely to experience constipation, but incorporating pumpkin seeds into meals and snacks can help you meet your needs. One ounce of roasted pumpkin seeds provides nearly 37 percent of your daily value for magnesium.
Beyond magnesium, pumpkin seeds also provide plant-based protein, unsaturated fat, iron, and zinc, making them a nutrient-dense snack or meal topping, Gaffen says.
2. Pumpkin Encourages a Healthy Gut Microbiome
Soluble fiber, such as that found in pumpkin flesh, has well-established prebiotic properties, meaning it serves as food for friendly gut microbes to support a healthy gut microbiome .
Because humans cannot fully digest these fibers, some reach the colon, where gut bacteria can ferment them and produce short-chain fatty acids (SCFAs), mainly acetate, propionate, and butyrate. "These compounds help connect what we eat with gut health," Gaffen says.
SCFAs support gut health by fueling colon cells, strengthening the intestinal barrier (which allows your body to absorb nutrients while keeping harmful substances out), regulating immune responses, and helping control inflammation.
Researchers have also found that pumpkin peels are rich in pectic polysaccharides, Gaffen says. They're a type of soluble fiber that may support beneficial gut bacteria while strengthening the immune system and gut barrier function.
3. Pumpkin Promotes Healthy Digestion
Potassium is an essential mineral that your body needs to work properly. This electrolyte sends signals to your brain, allowing muscles in your intestines to contract in a process known as peristalsis. Peristalsis pushes food through the intestines, allowing for proper digestion, absorption of nutrients, and elimination of waste.
For this reason, low potassium levels can lead to constipation as peristalsis weakens. "Because the digestive tract relies on coordinated nerve and muscle activity to move food through the intestines, potassium is important for normal digestive function," Gaffen says.
When you think of potassium-rich foods, bananas may come to mind, but 1 cup of cooked pumpkin actually contains more potassium than a large banana.
4. Pumpkin Supports a Healthy Gut Lining
Both the flesh and seeds of pumpkins are rich in certain nutrients that are needed to maintain a healthy gut lining. Pumpkin flesh is rich in beta-carotene, an antioxidant that is converted to vitamin A in the body. One cup provides 200 percent of the recommended daily intake and just 30 calories for those watching their weight.
Beta-carotene may also support gut health by helping maintain the intestinal barrier and regulate inflammation, according to animal studies. In human research, higher levels of beta-carotene and other carotenoids have been linked to greater diversity of gut bacteria.
Pumpkin seeds, on the other hand, are an excellent source of zinc , which supports immune function, tissue repair, and the proteins that help hold intestinal cells together, Gaffen says.
Research suggests that both vitamin A and zinc play a role in maintaining a healthy intestinal barrier, keeping food particles and bacteria from escaping the intestinal tract and causing inflammation.
5. Pumpkin Can Be Part of a Plant-Forward Diet, Which Boosts Gut Health
Eating a wider variety of plants can expose your gut microbes to different types of fiber, resistant starches (a type of carbohydrate), and phytonutrients (plant nutrients), Gaffen says. She cites the American Gut Project, now known as the Microsetta Initiative, which found that people who reported eating more than 30 types of plants per week had more diverse gut microbial communities than those eating 10 or fewer.
"Because gut microbes vary in which carbohydrates they can break down, eating a broader range of plants may support a wider range of microbial functions," she says.
Pumpkin is a practical but often overlooked way to add another plant into the rotation, Gaffen says. If you don't want to buy and cook a whole pumpkin, 100 percent canned pumpkin is available year-round, has a long shelf life, and provides similar fiber and nutritional benefits as cooked, fresh pumpkin, she says. It can be easily incorporated into other plant-based dishes, savory or sweet. "It can be added to oatmeal, yogurt, smoothies, soups, sauces, or baked goods," she says.
When blended, mashed, or cooked until fork-tender, it's also gentle enough for people with digestive conditions like IBD. "People with IBD don't need to avoid pumpkin simply because of their diagnosis. During periods of increased symptoms, soft, peeled, well-cooked pumpkin may be easier to tolerate," she says. Start with a smaller portion and increase gradually to help identify your tolerated amount, Gaffen says.
The Takeaway
-
Pumpkin is a great source of soluble fiber, magnesium, beta-carotene, and potassium, all of which can help with healthy digestion, gut motility, and bowel regularity.
-
It also supports a healthy gut microbiome because its soluble fiber feeds beneficial gut bacteria, promoting the production of short-chain fatty acids that strengthen the intestinal barrier, control inflammation, and regulate immune responses.
-
Canned pumpkin is available year-round and can be easily added to everything from oatmeal and smoothies to soups, sauces, and baked goods, making it a versatile option for adding more plant variety to your diet.
