Foods That Help (and Hurt) Digestion
Practical guidance for a comfortable gut — fiber, fermentation, herbs, and eating habits.

Most digestive complaints are not about a single food but about a pattern — too little fiber, too much speed, not enough chewing, not enough variety.
Fiber, slowly
Aim for 25–35 g of fiber daily from beans, lentils, vegetables, fruit, whole grains, and seeds. Increase gradually with plenty of water.
Fermented foods
Yogurt, kefir, sauerkraut, kimchi, miso — a small daily serving feeds beneficial gut bacteria.
Herbs that help
Fennel, peppermint, ginger, chamomile, and cumin all have a long tradition for digestion, with research increasingly to match.
Eat slowly
Most digestion begins with thorough chewing. Put down the phone.
When to seek help
Persistent symptoms, blood in stool, unintentional weight loss, or family history of GI disease warrant professional evaluation.
