Why Fiber Matters

Fiber is the part of plant foods your body cannot fully digest. It moves through your gut and supports regular bowel movements.

MedlinePlus says fiber can help with weight management, blood sugar control, constipation, diarrhea and cholesterol. It also helps you feel full.

Yet most people do not get enough. USDA research found the average American diet provided only about 58 percent of the recommended fiber in 2017 to 2018.

Soluble vs Insoluble Fiber

MedlinePlus explains that soluble fiber attracts water and turns to gel during digestion. Research shows it helps lower cholesterol.

Insoluble fiber adds bulk to stool and helps food pass more quickly through the gut. Most fruits and vegetables contain a mix of both.

High-Fiber Fruits

The Dietary Guidelines for Americans publishes a list of food sources of dietary fiber based on USDA data. These fruits rank near the top.

Berries are fiber superstars and easy to add to breakfast. Frozen berries work just as well and cost less in winter.

Pears and apples are great winter choices. See our guides to the best apples for baking and eating and how to eat a persimmon.

High-Fiber Vegetables

These values come from the Dietary Guidelines fiber list, which uses USDA FoodData Central. Cooked amounts pack more fiber per cup since vegetables shrink.

Brussels sprouts and sweet potatoes are easy wins. Try our guides on how to cook Brussels sprouts and sweet potato vs potato.

Avocado adds fiber and healthy fats. Read more in our avocado nutrition guide.

Beans, Peas and Lentils

Beans and lentils count as both vegetables and protein foods. They are some of the richest fiber sources you can eat.

Canned beans are a quick, budget-friendly option. Rinse them to reduce sodium.

Dried beans cost even less. Soak them overnight, then simmer until tender, and freeze cooked beans in small portions for later.

Easy Ways to Eat More Fiber

• Add berries to oatmeal, yogurt or cereal.
• Snack on an apple or pear with the skin on.
• Toss beans into soups, salads and tacos.
• Swap white rice for brown rice or add lentils.
• Roast a big tray of vegetables for the week.
• Keep frozen peas and broccoli on hand.

Overnight oats with berries make a high-fiber breakfast in minutes. Try our easy overnight oats recipe.

Roasting brings out sweetness in fiber-rich vegetables. Our roasted vegetables recipe shows how.

Frozen produce is just as useful as fresh. Compare them in frozen vs fresh vegetables.

Add Fiber Slowly

MedlinePlus advises that you slowly increase the amount of fiber in your diet. Adding too much too fast can cause gas and bloating.

1. Add one new high-fiber food every few days.
2. Drink plenty of fluids as you add fiber.
3. Cut back for a few days if you feel bloated.
4. Increase again slowly once you feel better.

MedlinePlus also warns that not getting enough fluids can make constipation worse instead of better. Water helps fiber do its job.

A Sample High-Fiber Day

A day like this can get many adults close to their fiber goal. Adjust portions to your needs and appetite.

Fiber, Blood Sugar and Heart Health

Fiber does more than keep you regular. MedlinePlus notes it can help people with diabetes manage blood sugar.

Soluble fiber slows how fast sugar enters the blood after a meal. That can help prevent sharp spikes and dips in energy.

Soluble fiber also helps lower cholesterol, which supports heart health. Oats, beans, apples and citrus are good sources.

• Pair fruit with protein, like an apple with peanut butter.
• Choose whole fruit instead of juice.
• Add beans to rice dishes to slow digestion.
• Start the day with oats or another whole grain.

If you have diabetes or heart disease, ask your care team how fiber fits your eating plan. A dietitian can help you build meals you enjoy.

Fiber and Gut Health

Fiber feeds the helpful bacteria in your gut. Some types act as prebiotics, which support those microbes.

Curious about supplements for gut health? Read our guide on whether probiotics work. Food sources of fiber are a great place to start.

Fiber Supplements vs Food

Fiber supplements like psyllium can help some people. MedlinePlus notes psyllium is a common soluble fiber supplement.

Whole foods offer more than fiber, though. Fruits and vegetables also provide vitamins, minerals and other helpful plant compounds.

Ask your doctor before starting a fiber supplement, especially if you take other medicines. Some supplements can affect how medicines are absorbed.

Reading Food Labels for Fiber

Packaged foods list fiber on the Nutrition Facts label. Look for the line called dietary fiber and its percent Daily Value.

• A higher percent Daily Value means more fiber per serving.
• Check the serving size, since it may be smaller than you eat.
• Look for whole grains as the first ingredient.
• Compare similar products side by side.

Fresh fruits and vegetables usually have no label. That is why lists like the Dietary Guidelines fiber table are so helpful.

High-Fiber Winter Meals

Cold months are perfect for hearty, fiber-rich dishes. Soups and stews make it easy to combine beans, vegetables and grains.

• Lentil and vegetable soup
• Black bean chili with squash
• Split pea soup with carrots
• Roasted root vegetables with chickpeas
• Barley and mushroom stew

Make a big pot and freeze extra portions. You will have a quick high-fiber lunch ready on busy days.

Winter produce like pears, citrus, squash and Brussels sprouts is also at its best. Leafy greens help too, so see our guide to kale vs spinach.

Fiber for Kids

Children need fiber too, though amounts vary by age. Offer a mix of fruits, vegetables, beans and whole grains every day.

• Serve berries or sliced pears at breakfast.
• Pack apple slices or carrot sticks in lunch boxes.
• Add beans to quesadillas or pasta sauce.
• Choose whole grain bread and cereals.

Add fiber gradually for kids too, along with plenty of water. A pediatrician can advise on your child’s needs.

Fiber Myths

Whole foods are the simplest way to boost fiber. Small changes at each meal add up quickly.

Saving Money on High-Fiber Foods

• Buy dried beans and lentils in bulk.
• Choose frozen berries and vegetables.
• Buy fruit that is in season.
• Use canned pumpkin and beans for quick meals.

Many of the highest-fiber foods are also among the cheapest. Beans, lentils and frozen peas cost little per serving.

Who Should Be Careful

• People with inflammatory bowel disease during a flare
• People told by a doctor to follow a low-fiber diet
• People recovering from bowel surgery
• People with certain swallowing or digestive conditions

Your doctor or dietitian can tell you which fiber foods are right for you.
