Can your child get too much fiber? Fiber is an important nutrient, but how much is too much? This post reviews fiber needs for kids and symptoms of too much fiber.
Fiber is an essential nutrient for health throughout all ages and stages.
It helps promote bowel regularity to support digestive health, and getting enough in the diet can reduce the risk for a number of chronic diseases, like diabetes, heart disease, and certain digestive cancers.
Luckily, fiber is super easy to find on a plant-based diet.
That’s because plants – including fruits, veggies, whole grains, legumes, nuts, and seeds – are the only sources of fiber! Animal products (meat, dairy, fish, eggs) don’t contribute fiber to our diets.
But while fiber is important, how can you tell if your child is getting too much of it? Is that even possible?
Fiber needs for kids
While most kids on a predominantly plant-based diet won’t have any trouble meeting minimum fiber requirements, it can be helpful to know what those basic needs are.
General fiber needs for children are as follows:
- Male and female, 1-3 years: 19 grams per day
- Male and female, 4-8 years: 25 grams per day
- Males, 9-13 years: 31 grams per day
- Females, 9-13 years: 26 grams per day
- Males, 14-18 years: 38 grams per day
- Females, 14-18 years: 25 grams per day
Staying within these ranges provides beneficial amounts of fiber without over-consuming and possibly causing upset tummies.

How much fiber is too much?
A child’s gut microbiome takes time to develop into a stable and diverse community of microorganisms. Interestingly, children’s gut microbiomes are more individualized compared to adults.
Therefore, children’s digestion of various plant fibers may respond differently.
Introducing a variety of plant foods containing pro- and prebiotics, starting as early as during the weaning phase, gives the opportunity to positively influence a child’s gut health.
For example, prebiotics found in bananas, asparagus, apples, and many other plant-based foods may be beneficial for children prone to constipation, because of their ability to increase microbes, bulk and soften stools.
But while fiber is an important nutrient, it’s possible for kids to consume more than they actually need.
Some of the signs that your child may be getting too much fiber include:
- Changes in bowel habits, e.g. looser stool than usual, or abnormal constipation (no stools)
- Complaints of abdominal pain
- Bloating
How much fiber is too much? It depends on your child. If you think these symptoms are likely due to fiber intake, it may help to examine exactly how much fiber your child is getting on an average day.
Another factor in promoting fiber tolerance for kids is hydration.
Hydration and fiber
One way to prevent risk for these symptoms is to make sure your child stays hydrated.
Kids who eat a high-fiber diet, but not enough liquid, are more likely to experience side effects. Water works with fiber to promote healthy digestion and passage of food and waste.
A general daily water recommendation for children is to consume enough 8 oz glasses of water to equal their age (eg., a 5 year old drinks 5 x 8 oz glasses per day).
A good tip is to get your child his or her own water bottle and keep it filled – and with you – throughout the day.
How to reduce fiber intake (if needed)
If you think your child is experiencing symptoms of too much fiber, and hydration isn’t helping, there are a few things you try do to reduce the amount of fiber in his/her diet:
- Swap out whole grain breads for white, enriched breads
- Remove peels or skins from fruit and veggies
- Switch to canned fruit or applesauce versus whole apples
- Avoid fiber-fortified foods, like orange juice with pulp or super seedy breads and granola bars
And of course, if symptoms continue or you have concerns, it’s always best to speak to your child’s healthcare provider.

Chime In: What are some of your child’s favorite fiber-rich foods? Have you ever wondered whether he/she is getting enough or too much fiber?
If you liked this article, we think you’ll enjoy some of these too:
Our child (5 years old) has perpetual “functional constipation” that has required medical intervention on a number of times. The generic advice we get from healthcare providers is always fiber and hydration (and MiraLax sigh). But I’ve wondered exactly this – is it too much fiber?? Can you have functional constipation as a result of too much fiber?
Yes, you can have too much fiber and have constipation. How much fiber does your child get? How much fluid? We can’t respond to personal medical nutrition needs online; but I would check those numbers and see how he is doing. If he’s getting too much fiber and not enough water then more fiber will only make constipation worse. On the other hand, if he’s only getting a handful of grams a day, then it’s likely not enough fiber.
Do you have a list of how much fiber is in foods ? I think my 1.5 years twins are getting too much but I’ve no idea how to monitor it . They are both very well hydrated.
