How Much Fiber Per Day Should You Eat?


Decades-long research has shown that high-fiber diets offer a multitude of health benefits. Although fiber or roughage is best known for promoting regularity and digestive health, it provides many other health benefits, such as maintaining healthy blood sugar levels and supporting heart health, depending on the type of fiber you eat. But how much fiber do you need per day for optimum health?

Keep reading to discover the daily recommended fiber intake, how to know if you are getting enough fiber each day, and ways to get more fiber in your diet.

How Much Fiber Should I Eat Every Day?

Although the U.S. Department of Agriculture (USDA) recommends that adults consume about 28 grams of fiber daily 1, but the average U.S. adult consumes just 16 grams of fiber per day. That means fewer than 10% of Americans get enough fiber from food.1 The takeaway from all of this? American adults need more fiber in their diets.

If you think you’re not getting enough fiber from your diet, start by increasing the plant-based foods in your diet. Most plant foods contain varying amounts of fiber. Some of the best sources are vegetables, fruits, legumes, whole grains, nuts, and seeds. You can tap into the many health benefits of high-fiber diets by upping how much of fiber-rich foods you eat regularly.

3 Signs You’re Not Eating Enough Fiber

If you’re not getting enough fiber from your food, your body will signal to let you know. These are some of the most common signs you should look out for.

You feel hungry soon after eating.

Foods that are low in fiber tend to leave you reaching for a snack soon after finishing your meal. If you constantly find yourself hungry, log your diet habits for a week or so and determine the fiber content of your meals.

When the bulk of your diet consists of foods rich in dietary fiber, you tend to feel full longer. If eating more fiber-rich, plant-based foods is still not enough, fiber supplementation may be a great way to up your intake and keep you full between meals. For example, one study found that psyllium supplementation contributes to greater fullness and less hunger between meals.2

Both types of dietary fiber - soluble and insoluble - play a role in ensuring food moves through your digestive tract smoothly. Soluble fiber draws in water and can help with bowel movements. Insoluble fiber helps by adding bulk to your stool and moving food through your digestive tract. Although it's important to have both types of fiber in your diet, you don’t have to worry much, because eating a wide variety of plant-based foods will help you get plenty of each.

You feel sluggish and weighed down.

Your body needs carbohydrates for energy, and low-carb, low-fiber diets can leave you feeling sluggish and weighed down. Be sure to include ample amounts of dietary fiber—a non-digestible form of carbohydrate—in your diet to feel more energized throughout the day.

You experience occasional constipation.

If you struggle with not having regular bowel movements or having difficulty passing stools, you are certainly not alone. Constipation affects almost 20 percent of the North American population.3 Although it is one of the tell-tale signs that you may not be consuming enough fiber-rich foods, it's best to contact your healthcare provider if you have any questions or concerns.

How Do I Get More Fiber in My Diet?

Meeting the recommended daily fiber intake does not have to be complicated. You don't need a complete diet overhaul; a few simple changes may be enough to increase the amount of fiber you eat each day. Keep reading for simple ways to get more fiber in your diet.

Add fruits and vegetables to every meal

Regardless of what your current diet looks like, commit to upping your fruit and vegetable intake with your breakfast, lunch, snacks, and dinner. So, for instance, if your typical breakfast is a bowl of cereal, add a cup of fresh raspberries to get an additional 8 grams of fiber.4

For snack, try broccoli and a banana. A cup of broccoli provides about 2 grams of fiber, and a banana about another 2 grams of fiber.4 As you can see, increasing your fiber consumption is not difficult or time-consuming. You can chop the fruits and veggies in few minutes and eat them on the go.

Take a fiber supplement

Eating more plant-based foods is a great way to get more fiber plus the other nutrients your body needs. But it’s challenging to get enough to reach the 28g needed daily. So, as you add more fruits and vegetables, nuts, and seeds to your diet, supplement with Metamucil made with plant-based psyllium fiber. Metamucil Orange Smooth Sugar-Free Powder provides 3 grams of fiber per serving, about 10 percent of your recommended daily fiber intake. Add a rounded teaspoon of Metamucil Orange Smooth Powder to a glass of water and start your day on the right note by increasing your fiber intake.

Metamucil Fiber Gummies are an excellent option if you prefer taking supplements in gummy form. These orange-flavored fiber supplement gummies contain a prebiotic, plant-based fiber blend to support your digestive health* and 5 grams of fiber per serving with no added sugar.

Start your day with a tropical fruit smoothie

No matter how little time you have in the morning, in less than 5 minutes, you can make a delicious, nutrient-packed, fiber-rich smoothie. Here’s a tropical fruit smoothie recipe:

Add ½ cup vanilla low-fat yogurt, ½ medium peeled banana, 1/3 cup mango or papaya juice, 1 serving of Metamucil Orange Smooth Powder, and crushed or cubed ice. Blend and add ice until you reach your desired consistency.

With 5 grams of fiber, this smoothie is a great and tasty breakfast for anyone looking to up their fiber intake.

Snack on Metamucil Fiber Thins

Make the most of your afternoon snack by treating yourself with Metamucil Chocolate Fiber Thins. One serving contains 5 grams of fiber and only 100 calories. Not a fan of chocolate flavor? Try Metamucil Cinnamon Spice Fiber Thins, or Metamucil Apple Crisp Fiber Thins instead.

Eat a handful of nuts and seeds

Sunflower and pumpkin seeds make an excellent addition to any salad. With their unique nutritional profile, crunchy texture, and generous fiber content, they deserve a spot on your plate. Be mindful, however, that nuts are relatively high in calories, so don't go overboard.

How much fiber do nuts and seeds provide?4

  • 1 cup of whole almonds has almost 18g of fiber
  • 1 cup of chopped walnuts has about 8g of fiber
  • 1 cup of halved pecans has almost 10g of fiber
  • 1 oz of chia seeds has almost 10g of fiber

There are so many ways to up your fiber intake, many of which require little to no time commitment. Whether you start by adding a piece of fruit to your meals, snack on Metamucil Fiber Thins, or sprinkle almonds on your salad, you will be sure to reap the benefits of getting more fiber in your diet.
