It's no wonder that some of the healthiest foods are also fiber powerhouses, with a slew of health-boosting benefits. This all-important, plant-derived nutrient is vital for optimal gut health and overall well-being. That's why fiber should play a pivotal part in anyone's diet—including kiddos! 

Yet, it is estimated that only 5% of American adults and children get an adequate amount of dietary fiber. That's a pretty big problem, considering, "Studies show that children who eat fiber-rich diets have a reduced risk of obesity and chronic diseases later in life," says Whitney English, M.S., RDN. Fiber can also help prevent constipation—a common problem for young children.

What's more, "Fiber helps feed children's developing microbiome, which sets the stage for their lifelong health—the microbiome does everything from helping to digest food to regulating metabolism to influencing immune responses," says English.

Those first three years of life are especially crucial because it's when a child develops their microbiome, says William Bulsiewicz, M.D., MSCI, best-selling author of Fiber Fueled. "We need to view this as an opportunity to support the healthiest gut microbiome possible by feeding it with prebiotics," he says. "There are two main sources that are relevant, human breast milk and the fiber found in plant foods."

How much fiber do kids need?

Ensuring proper fiber consumption is key to promoting your child's health—but what exactly is dietary fiber, anyway?

Usually called roughage, dietary fiber is a plant-derived food component that is not digested by the body. It moves through the digestive system and then out of the body. There are two kinds of dietary fiber: soluble fiber or viscous (think fruits and veggies) and insoluble fiber or bulking (think whole grains and chia seeds). To ensure you're getting both types, most health experts recommend eating a variety of nutritious, fiber-rich foods.

But how do you know how much fiber your child requires to meet an adequate fiber intake? It varies by age. Here's an estimate for different age groups, according to the Cleveland Clinic:

  • Children 1 to 3 years: 19 grams of fiber/day.
  • Children 4 to 8 years: 25 grams of fiber/day.
  • Boys 9 to 13 years: 31 grams of fiber/day.
  • Girls 9 to 13 years: 26 grams of fiber/day.
  • Boys 14 to 19 years: 38 grams of fiber/day.
  • Girls 14 to 19 years: 26 grams of fiber/day

While consuming enough fiber is critically important for optimal health, too much fiber or an imbalance of soluble and insoluble fiber might become a problem. Ideally, you want to start by increasing the amount of plant-based, fiber-rich foods in your child's diet bit by bit to prevent unwanted side effects such as gas, diarrhea, bloating, or tummy aches. Also, make sure to focus on hydration as you increase their fiber intake.


15 high-fiber foods for kids.

If you're looking to incorporate some fiber-rich foods into your child's diet, here are a few (picky-eater-friendly) favorites to help your kiddos stay healthy for years:

1. Ancient grains

Whether it's kamut, teff, sorghum, amaranth, millet, fonio, farro, rye, freekeh, quinoa, or barley—ancient grains are a compelling, nutrient-rich staple worldwide.

What about supplements?

Fiber supplements should never supersede a diet rich in high-fiber foods. However, these may help if you find it tough to meet your child's daily fiber intake through fruits, veggies, whole grains, seeds, and nuts. Just be sure to consult with your pediatrician before adding any type of supplement to your child's diet.

If you decide to opt for a fiber supplement, high-quality fiber gummies or a nourishing greens powder may be good options. Make sure to read the supplement labels first to guarantee the best ingredient list possible, free of additives, added sugar, and other processed ingredients.

Bottom line.

To fill your child's daily fiber intake, include a diversity of seeds, nuts, legumes, veggies, and fruits in their diet.
