    Hi! I’m Jill Castle, MS, RDN, a pediatric nutritionist and registered dietitian. I’ve spent my 30-year career helping parents nourish healthy kids with nutritious foods, effective feeding strategies, and healthy habits that last a lifetime. I integrate these three areas in all my work and believe this is the cornerstone of raising healthy kids and cohesive, connected families. I’m the founder of The Nourished Child®, the only website dedicated to parent education about childhood nutrition, feeding kids, and raising nourished ones, inside and out. You can find free articles, classes, audio lessons/podcasts and other comprehensive resources.

    I mentor other pediatric professionals in business development, so they can grow professionally and help more parents. If you’re a pediatric nutrition professional, check out my mentoring programs and other resources here.

    Additionally, I’m an author of 5 books, speaker, media dietitian, and nutrition consultant for the food industry and start-up companies targeting the kid’s space.

    Last, but certainly not least, I’m a mom and have raised four kids, so I intimately know the ups and downs parents experience, understand the challenges and successes of feeding and raising children. Poke around my website — there’s a lot to discover!



    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!
