Fiber is an indigestible part of food that helps us poop regularly, keeping our bowels and intestines healthy.
Fiber digests very slowly, which helps to stabilize blood sugar and keep us feeling full, but a high-fiber diet also reduces the risk of stroke, hypertension, and heart disease. Too much or too little fiber can cause digestive issues — the ideal amount is about 38 grams per day for men and 25 grams for women. Despite popular preconceptions, there is no proven link between a high fiber diet and a reduced risk of bowel cancer.
Good sources of fiber include legumes, green vegetables, berries, avocados, seeds, and whole grains. Fiber is only found in plant-based foods.
