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

Child Nutrition Writer & Author

As a nutrition writer who writes about child nutrition and feeding, my learning curve has been wide and steep.

Early in my career as a pediatric nutritionist, 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 weekly blog, childhood nutrition articles, and in the books with which I have been involved.

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 child 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 latest science in sports nutrition for the young athlete.

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!
