Why is fiber important?
Dietary fiber, a type of carbohydrate that the body can’t digest, comes from plants, such as fruits, vegetables, whole grains, legumes, beans, nuts, and seeds.
Fiber is often best known for its role in the regulation of our bowels. Studies indicate that it can be very helpful in both preventing as well as managing constipation, as well as maintaining regularity.13
However, fiber has been found to do so much more! Diets higher in fiber can help reduce the risk of heart disease, stroke, high blood pressure, and diabetes.23 In fact, in epidemiological studies, populations with higher dietary fiber intakes tend to have lower chronic disease rates overall.4
Types of fiber
There are two categories of dietary fiber: soluble and insoluble. Most plant foods contain both types.
Soluble fiber dissolves in liquid and forms a gel in our stomachs, which helps to slow down digestion.5 It can bind to fats and can help reduce cholesterol, in addition it slows down the absorption of sugars, helping normalize blood sugar levels.678
Good sources include oat bran, barley, peas and beans, nuts, seeds, and most fruits and vegetables. In addition, psyllium husks and chia seeds are especially high in soluble fiber—if you’ve ever stirred them into a liquid, you know just how gelatinous they get!59
Insoluble fiber, on the other hand, doesn’t dissolve in liquid but rather stimulates the large bowels to increase stool water content, making stool easier to pass.10
Good sources include wheat bran, whole grains, and vegetables.5
How much fiber is needed?
Both soluble and insoluble fiber are considered together in dietary fiber recommendations. Your daily recommendations for adequate intake of dietary fiber vary by age, gender, and life stage.
While these recommendations apply to most people, if you have certain digestive or bowel disorders your healthcare provider might have asked you to reduce the amount of fiber in your diet.
The recommended daily intake of fiber is 14 grams per 1,000 calories.11 This amounts approximately to the following dietary fiber recommendations.
*Note that the number for children are based off their Daily Value (DV), or the amount of fiber needed based on average calorie intake at this age range.
Child and adolescent fiber recommendations:
Children* 1 to 3 years: 14 g
Girls 4 to 8 year: 17 g
Boys 4 to 8 years: 20 g
Girls 9 – 13 years: 22 g
Boys 9 – 13 years: 25 g
Adolescent girls 14 – 18 years: 25 g
Adolescent boys 14 – 18 years: 31 g

Men 19 – 30 years: 34 g
Women 31 – 50 years: 25 g
Men 31 – 50 years: 31 g
Women 50 + years: 22 g
Men 51+ years: 28 g
Pregnancy and lactation fiber recommendations:
Pregnant women ages 19 – 30 years: 1st trimester: 28 g; 2nd trimester: 34 g; 3rd trimester: 36 g
Pregnant women ages 31+ years: 1st trimester: 25 g; 2nd trimester: 31 g; 3rd trimester: 34 g

Fiber in your, your baby, and your toddler’s diet
Fiber for you
Fiber (and extra fluids!) are particularly important during pregnancy and postpartum when constipation can be a common complaint.1213 In addition to dietary sources, fiber supplementation may be very useful. Chat with your health care provider about whether a supplement may be helpful for you.
Including plenty of vegetables, fruit, whole grains, nuts, seeds, beans, and legumes in your everyday diet will help you get to your fiber intake goal. Try to include vegetables at both lunch and dinner, fruit at snacks and breakfast, and choose whole grains when possible. Top salads and yogurt with nuts and seeds, include veggies such as kale or spinach in smoothies, and you can give chia seed-packed overnight oats a try.

Fiber for your baby and toddler
To help get your little one into the habit of enjoying fiber-rich foods, begin introducing these tastes once your baby starts eating solids. Studies indicate that the more often you introduce foods, including vegetables, the more likely it is that your baby will accept them both now and in the future.1415
Offer vegetables and fruits every day; choosing and preparing foods that are a texture your child can handle. Beans and legumes are a great weekly addition to their diet as well. Getting your child used to eating whole grains is also important for fiber and nutrient intake.
The good news is that these foods are not only sources of fiber, but also many other vitamins and minerals as well.

Drink enough fluids
While increasing fiber is normally a good thing, without increasing water at the same time you or your child may experience gas, bloating, or more constipation.17
Be sure to increase fiber in your or your child’s diet slowly and drink plenty of fluids to help keep your bowels moving regularly.

Consider fiber supplementation if needed
If you need fiber supplementation because you are experiencing constipation or need extra fiber for other reasons, you have options.
Fiber supplements on the market include those with psyllium, methylcellulose, and wheat dextrin. You can also simply add wheat bran, oat bran, or ground flax seeds to your salads, oatmeal, or smoothies. Be sure to always increase fluids when you increase fiber to help prevent more constipation.
Always consult with your healthcare provider before taking anything new.
