All about fiber: Why it matters and how to increase your intake

Fiber is a plant-based nutrient that’s important for keeping your body’s digestion running smoothly. Unlike most other carbs, fiber resists digestion in your small intestine, so it travels through your body mostly unchanged. This trait is what makes fiber so beneficial. Some fibers are fermented in the colon, producing short chain fatty acids that support gut health.

Soluble fiber can help lower LDL cholesterol and slow the absorption of glucose, helping support healthy blood sugar levels. On the other hand, insoluble fiber assists in moving food along your digestive tract, making it great for avoiding constipation and keeping things regular.

Diets high in fiber are associated with a lower risk of heart disease, Type 2 diabetes, colorectal cancer and some gastrointestinal conditions. Understanding the value of a high-fiber diet is the first step toward increasing your intake and improving your overall health.

Current dietary guidelines recommend that women ages 19 to 30 consume 28 grams per day. For women ages 31 to 50, the recommendation is 25 to 28 grams per day. For women age 50 and older, the recommendation is 22 grams per day.

For men ages 19 to 30, current dietary guidelines recommend 34 grams per day. For men ages 31 to 50, the recommendation is 31 to 34 grams per day. For men age 50 and older, the recommendation is 28 grams per day.
