Top 5 Sources of Prebiotic Fiber for Kids to Support Constipation

Incorporating sources of prebiotic fiber into your kid’s diet is one way to support a healthy gut and support constipation relief. Prebiotic fiber can be obtained from various food sources or through a kid’s prebiotic supplement such as our Growing Up Prebiotic. Prebiotics, like chicory root fiber, provide nourishment for good bacteria in our little one’s digestion to promote softer stool and a balanced microbiome [3,4].

In this article, we will explore the benefits from some of the top food sources of prebiotic fiber that you can easily incorporate into your kid’s daily meals and snacks. By incorporating these fiber sources, you'll nourish your little one’s growing microbiome and encourage regular bowel movements.

Apples

Apples are abundant in prebiotic fiber, particularly pectin, which serves as nourishment for beneficial bacteria and supports the growth of anti-inflammatory bacteria [1]. Encourage your little one to enjoy a crisp apple as a healthy snack or incorporate sliced apples into salads, snack-cuterie boards, or oatmeal.

Bananas

Bananas contain a type of fiber called inulin, which promotes the growth of friendly gut bacteria [2]. Incorporate ripe bananas into smoothies, slice them onto whole-grain toast, or freeze them for a refreshing and healthy snack.

Oats

Oats contain a unique type of fiber called beta-glucan, which acts as nourishment for beneficial gut bacteria [3]. Making oatmeal with yogurt or kefir can add some extra probiotic benefits, making it a balanced, gut nourishing meal. Top it with sliced fruits for extra nutrients and to add some natural sweetness.

Avocados

One medium avocado contains 9 grams of fiber from pectin, which is a source of prebiotic fiber [1]. Try adding avocados into sandwiches, dips, or even blending it into smoothies for a creamy, nutrient boost.

Growing Up Prebiotics

Do you have a picky eater? Our Growing Up Prebiotics might be a helpful solution. Each serving contains 3 grams of plant-based fiber from chicory root to support softer stools [5]. It also contains a 2’-FL HMO (Human Milk Oliggiosachiade), a prebiotic that feeds and nourishes the friendly gut bacteria in the gastrointestinal tract, where 70% of our immune system is located [6]. Contrary to its name, it’s not from human milk but does contain the same structure and benefits as the prebiotics in human breast milk. The best part? Our Growing Up Prebiotics are tasteless and textureless, so you can easily add it to your kid's favorite beverages to increase their fiber intake. Clinical research has shown that consistent use of our chicory root fiber can increase stool frequency, soften consistency, and reduce pain in just six weeks [5].

How much fiber is in these foods?

The following chart lists the percent of the recommended daily allowance for fiber that each serving of these foods provides.

This is based on the RDA of:
