The Importance of Fiber for Health: Top Food Sources and Tips

The Importance of Fiber for Health

Fiber is an essential part of a healthy diet. Consuming adequate fiber can provide many health benefits and prevent various diseases. Most Americans do not get enough fiber in their daily diets, so making a conscious effort to add high-fiber foods is important.

What is Fiber and Why is it Important?

Dietary fiber, also referred to as roughage, is the indigestible part of plant foods. It passes through the digestive system relatively unchanged. There are two main types of fiber:

• Soluble fiber - dissolves in water to form a gel-like material. It can help lower glucose and cholesterol levels.
• Insoluble fiber - does not dissolve in water. It helps food move through the digestive system and promotes regularity.

Consuming enough fiber plays a key role in:

• Supporting digestive health
• Controlling blood sugar levels
• Lowering cholesterol
• Aiding weight management
• Reducing disease risk

Current Fiber Intakes and Recommendations

Despite its benefits, research shows that most Americans fall short when it comes to daily fiber intake. On average, American adults consume only 16 grams per day. Experts recommend between 25-40 grams of fiber per day depending on age and gender.

Children and adults should aim to increase their fiber intakes to reap important health rewards. Adding more high-fiber foods into your diet can help achieve this goal.

Top Sources of Dietary Fiber

Many delicious foods can help boost your daily fiber content. Focusing on high-fiber options whenever possible can go a long way toward better health.

1. Beans, Peas, and Lentils

Legumes like beans, peas, and lentils contain impressive amounts of fiber. Just a half-cup serving of cooked beans or lentils provides between 4-8 grams of fiber.

Some great legume choices high in fiber include:

• Kidney beans
• Pinto beans
• Navy beans
• Black beans
• Garbanzo beans
• Split peas
• Lentils

Aim to incorporate beans, peas, or lentils into recipes like soups, stews, salads, and grain bowls several times per week.

2. Nuts and Seeds

All types of nuts and seeds supply fiber, along with protein and healthy fats. Just an ounce (about 28 grams) of almonds, pecans, pistachios or sunflower seeds contains between 3-4 grams.

Great high-fiber options include:

• Almonds
• Pistachios
• Pecans
• Hazelnuts
• Peanuts
• Flaxseeds
• Chia seeds
• Sunflower seeds

Enjoy nuts as snacks, sprinkled on oatmeal or salads, blended into smoothies and much more.

3. Fruits and Vegetables

All types of produce can contribute fiber to your diet. Generally, fruits and vegetables with edible skins and seeds will be highest.

Some top high-fiber fruits and veggies are:

• Raspberries
• Pears
• Apples
• Bananas
• Broccoli
• Greens like spinach and kale
• Artichokes
• Brussels sprouts
• Carrots

Aim for a minimum of 2-3 servings of fruit and 2-3 servings of vegetables daily as a good foundation.

4. Whole and Ancient Grains

Choose whole grain versions of breads, rice, pasta and ancient grains like farro, spelt, and barley more often to up your fiber game. Refined grains contain very little fiber compared to their whole counterparts.

Just one ounce of whole grains provides:

• Oats - 4 grams
• Popcorn - 3 grams
• Brown rice - 2 grams
• Whole wheat bread - 2 grams
• Rye - 2 grams
• Quinoa - 2 grams

Some easy ways to enjoy whole grains include oatmeal, brown rice bowls, quinoa salads and toasted whole grain bread.

5. Chia Seeds and Flax Seeds

These small seeds pack an incredible fiber punch. Just 2 tablespoons of chia seeds provides 10 grams of fiber, while the same amount of flaxseed meal delivers 8 grams.

These seeds are easy to incorporate into smoothies, oatmeal, yogurt, baked goods and more.

6. Popcorn

This whole grain snack is surprisingly high in fiber, even for the low-calorie versions. Air-popped popcorn provides about 4 grams of fiber per 3-cup serving. Look for 100-calorie snack packs to easily limit portions.

7. Berries

Blackberries, raspberries and strawberries all supply around 4 grams of fiber per one-cup serving. Blueberries are bit lower at 3.5 grams per cup but still a great choice.

Enjoy berries sprinkled on oatmeal, yogurt, salads or blended into smoothies.

8. Avocados

Creamy, buttery avocados provide nearly 10 grams of fiber per medium-sized fruit. They make a great addition to salads, smoothies, sandwiches and more to significantly up your fiber content.

9. Sweet Potatoes

These vibrant orange spuds are an excellent source of fiber and vitamins. A medium cooked sweet potato with skin on packs over 4 grams of fiber.

Try roasted, mashed or as baked sweet potato fries.

10. Prunes

These dried plums are well known for their high fiber content. About 40% of the fiber found in prunes is soluble, helping regulate blood sugar levels.

A quarter cup of prunes provides nearly 4 grams of fiber. They make a great easy snack or can be added to trail mixes.

Tips to Increase Your Fiber Intake

Use some of the following practical strategies to boost the fiber content of your daily diet:

Eat More Fruits, Vegetables and Whole Grains

Make fruits, vegetables and whole grains the foundation of your meals and snacks. They all contribute higher levels of fiber.

Limit Refined Carbs

Cut back on refined carbohydrate foods like white breads, sugary cereals and crackers which contain little to no fiber. Replace them more with whole food high-fiber alternatives instead.

Add Seeds to Foods

Sprinkle chia seeds, ground flaxseeds, hemp seeds and sesame seeds onto cereals, salads and yogurts to increase fiber content.

Enjoy Smoothies with Produce and Seeds

Blend up berry smoothies with spinach or kale and seeds like flax, chia or hemp seeds for an easy high-fiber boost.
