Learn how to add more fiber to your diet with 12 simple food swaps, a high-fiber sample day, fiber amounts in common foods, and tips to avoid bloating.
The easiest way to add more fiber to your diet is to make small swaps at each meal: whole grains instead of refined, a serving of beans or lentils most days, fruit with the skin on, and a handful of nuts or seeds. Increase slowly over a few weeks and drink enough water, and most people can move much closer to the recommended amount without much discomfort. Commonly cited US guidance is about 25 grams a day for women and 38 grams for men, and most Americans fall well short.
Fiber is one of the most consistently supported parts of a healthy diet. It helps with regular digestion, helps you feel full, and diets rich in fiber are associated with better heart health and more stable blood sugar. Here’s how to get more without overhauling everything you eat.
Soluble vs. insoluble fiber
There are two main types, and most plant foods contain both. Soluble fiber dissolves in water to form a gel; it’s found in oats, beans, apples and chia, and it’s the type linked with helping manage cholesterol. Insoluble fiber adds bulk and helps things move along; it’s found in whole wheat, bran, nuts and the skins of fruits and vegetables. You don’t need to track them separately. Eating a variety of plant foods covers both.
Fiber in common foods
Amounts vary by brand, variety and preparation, so treat these as approximate. Checking the Nutrition Facts label on packaged foods is the most reliable way to know.
