As 2026 starts, digestive health is becoming a major focus, and the produce section at your local grocery store might be the best place to kick things off. In the past year, dietary fiber has really stepped into the spotlight, competing with protein as more Americans lean towards whole foods that boost digestion, metabolism, and gut health.
Fruits, from tropical wonders to seasonal picks, are packed with fiber, prebiotics, and antioxidants, things that experts suggest can nurture a healthy gut microbiome. “The more fiber you consume, the more ‘good bacteria’ can thrive in your gut,” says Robin DeCicco, a holistic nutritionist in New York City. Good bacteria are essential—they help with digestion, absorption of nutrients, inflammation reduction, and they even keep bad bacteria at bay.
DeCicco adds that a fiber-rich diet enhances the intestines’ ability to absorb vitamins and minerals while promoting regular bowel movements, which is crucial for gut health. The U.S. Dietary Guidelines recommend that adults strive for 22 to 34 grams of fiber daily, yet many folks don’t meet this target.
Experts highlight two servings of certain fruits daily to improve gut health and possibly lower cancer risk. Here are five fruits you might consider adding to your diet this year.
1. Kiwi
Having two kiwis a day could enhance digestion, alleviate constipation, and even lower colorectal cancer risk due to their fiber-rich profile—about 8 grams per fruit—and a special enzyme known as actinidin. Dr. Trisha Pasricha, a gastroenterologist, notes that while no single fruit is a magical solution for gut issues, kiwis may outperform traditional choices like prunes or psyllium.
2. Passion Fruit
This fruit is notable for having around 25 grams of fiber per cup. Besides fiber, it also boasts a decent protein content and is packed with antioxidants, aiding in digestive health and regularity.
3. Peach and Plum
Peaches and plums are gaining traction as great gut enhancers, combining fiber with hydration. Peaches, made up of about 89% water, alongside their fiber, vitamin C, and potassium, support digestion and overall gut function. Plums, too, offer significant fiber and natural sorbitol, which can help relieve constipation.
4. Oranges and Other Citrus Fruits
Citrus fruits like oranges not only support gut health but may also benefit mental well-being. A recent study found that regular consumption of these fruits was linked to a 20% lower risk of depression, indicating the relationship between fiber-rich foods and mental health. That said, the study doesn’t replace conventional antidepressant treatments.
5. Figs
Figs provide about 5 grams of fiber per serving, contributing to digestion and gut health. Their sweet pulp and tiny seeds offer both soluble and insoluble fiber, promoting regularity while also being rich in antioxidants and essential minerals. Dried figs can have up to 10 grams of dietary fiber per 100 grams.
Experts suggest that pairing fruit with protein and healthy fats can help regulate sugar absorption and stabilize blood sugar levels post-meal.
