How does fiber in food affect your digestive health?

Fiber plays a crucial role in digestive health by adding bulk to stool and helping it move through the intestines more efficiently, which prevents constipation and promotes regular bowel movements. Soluble fiber, found in oats and beans, dissolves in water to form a gel-like substance that slows digestion and feeds beneficial gut bacteria. Insoluble fiber, found in whole grains and vegetables, adds bulk and speeds up transit time through the colon. A fiber-rich diet supports a healthy gut microbiome, reduces the risk of colorectal cancer, and can lower the chances of developing diverticular disease. It also helps maintain a healthy intestinal lining. Most adults should aim for 25 to 38 grams of fiber per day for optimal digestive function.
