This week, I want to highlight fiber, a nutrient that most Americans are not getting enough of. Fiber is a type of carbohydrate found in plant foods that our digestive enzymes cannot fully break down. Instead of being completely digested and absorbed, much of it travels through the digestive tract to the large intestine. There, fiber can help add bulk to stool, support regular bowel movements, and feed beneficial gut bacteria. Those bacteria can break down some types of fiber and produce compounds that help nourish the cells lining the gut, supporting overall gut health. Fiber may also support heart and metabolic health. The 2025 Dietary Guidelines Advisory Committee Report notes that higher dietary fiber intake is associated with a reduced risk of coronary heart disease. Despite these benefits, only about 6% of Americans ages 1 and older consume fiber above the recommended Adequate Intake level. Fiber is found in foods like fruits, vegetables, whole grains, beans, peas, lentils, nuts, and seeds. A few easy ways to add more fiber: - Choose whole grains - Add fruit to breakfast or snacks - Include beans or lentils in meals - Add more vegetables, nuts, or seeds throughout the day Small changes can add up. Try adding one more fiber-rich food to your meals this week.
