    I’m a pediatric dietitian, author, speaker, and consultant with a deep history in educating parents about childhood nutrition. I show aspiring pediatric nutrition professionals, organizations and start-up companies how to reach parents and families with their businesses, products, and services so they can have a radical impact on children’s health.

    My clients gain my in-depth knowledge, experience and insight as a nutrition entrepreneur and experienced health professional. Instead of wasting time and money on developing products and services, or wondering what families need or want, my clients fast-track to success.

    I’ve had a 30+ year career of working in clinical settings and private practice. As an author of five books (and a 6th one on the way), I aim to inspire parents and caretakers to nourish the next generation so they grow up healthy, inside and out. I created The Nourished Child®, a nutrition website dedicated to educating parents about feeding children. There, you will find free articles, classes, audio lessons/podcasts and other comprehensive resources that make feeding families easier.

    The Nutrition Prescription for Healthier Kids  | Jill Castle | TEDxDanbury


    In 2017, I appeared on the TEDx stage. My talk, The Nutrition Prescription for Healthier Kids, focused on what it will take to help our nation's children truly be healthier. I challenged my audience to shift their focus from a “food will fix our kid’s health problems” to a modernized perspective on child nutrition, including the integration of food, feeding and childhood development.

    I hope you'll watch!
