Picky Eating and Poop Problems: Is There a Connection?

As a pediatric dietitian, I’ve worked with many families who are concerned about picky eating. And as a mom of two, I get it! We all want the best for our kiddos and that includes making sure they are getting the nutrition they need. 

While picky eating can be a normal part of development, it’s helpful to be aware of what side effects may occur and how to work through them. So if you’ve ever wondered if picky eating and poop problems are connected, this one’s for you!

First, let’s talk a little about what picky eating can look like, knowing that the experience differs from kiddo to kiddo. Often, picky, or selective, eating means kids will only eat certain foods and are unwilling to try new foods. This can lead to a diet with little variety as well as feelings of kids not eating “enough.” These factors may lead to digestive issues such as constipation or diarrhea in picky eaters. 

Constipation in Picky Eaters

Generally speaking, picky eaters are drawn to “safe” foods that tend to be highly-palatable. Things like crackers, pasta, breads, etc. While these foods can definitely offer nutritional benefits and be part of an overall healthy diet, they can also be low in fiber. This may lead to constipation in picky eaters, especially if they aren’t drinking enough water or eating many foods rich in water, such as fruits and vegetables.  

Diarrhea in Picky Eaters

Conversely, many “safe” foods for picky eaters may contribute to diarrhea. The reason for this is that carbohydrate-heavy foods are broken down to sugar in the body. Large loads of sugar may cause diarrhea by pulling water into the small intestines during digestion. 

Summary

Picky eating is a normal part of development for many kiddos. However, it can contribute to pooping problems such as constipation and diarrhea. It’s important to work with a healthcare provider to address the issues with diet and other lifestyle factors.
