I Write about Nutrition for Kids

I’m a pediatric nutritionist who loves to write about childhood nutrition and feeding kids.

But, my learning curve has been steep.

Early in my career as a pediatric dietitian, I wrote scientific research articles and textbook chapters.

Now, I translate the science into understandable tips and practical advice for parents and practitioners on my blog, in childhood nutrition articles, and in the books with which I have written and been involved.

“I make the evidence come alive and translate it into practical information families and professionals can use right away.”

Fearless Feeding by Jill Castle, MS, RDN and Maryann Jacobsen, MS, RDN

My experiences as a childhood nutritionist and mom have shaped my vision about nutrition.

So much so, I partnered with a like-minded dietitian and wrote a comprehensive resource on childhood nutrition called Fearless Feeding: How to Raise Healthy Eaters from High Chair to High School.

Fearless Feeding breaks down nutrition and feeding for each stage of childhood, including infancy, toddlerhood, childhood and adolescence.

My book for young athletes is called Eat Like a Champion: Performance Nutrition for Your Young Athlete.

This book is for parents and coaches of young athletes aged 8 to 18. It showcases the science in sports nutrition for the young athlete.

Eat Like a Champion - Performance Nutrition for Your Young Athlete by Jill Castle, MS, RDN

Not only do you get the science aimed at kids and teens, you get practical advice for how to put it into daily practice.

This book is a game changer for young athletes! 

Author of The Smart Mom’s Guide Series

I love to write and have committed myself to writing helpful books for parents so they understand nutrition for kids better and use positive feeding practices. Here are my current offerings and there are more in the works!

My books are available on Amazon or on my parent education website, The Nourished Child®.

Child Nutrition Articles

As a nutrition writer, I’ve also written for other sports-oriented websites, such as USA Swimming, US Rowing, the National Alliance for Youth Sports magazine, Sporting Kids, USA Field Hockey, and Golf magazine.

For years, I wrote for Bundoo, a site for children ages 0-4 years,, and Wee Feed.
