You have probably seen it in your feed: "Seed oils are toxic." "Omega-6 fats cause inflammation." "Never cook with vegetable oil." But is any of that actually true? And more importantly, what does it mean for what you are feeding your children? In this episode, I sit down with Dr. Martha Belury, a registered dietitian and professor at The Ohio State University who has spent more than 30 years studying fatty acid metabolism. She is one of the few researchers in the world who has actually tested the omega-6 theory in clinical settings, and her findings may surprise you. We cover: • What omega-6 fatty acids are and why they are considered essential nutrients • The only two fatty acids your body cannot make on its own and why children need them for healthy growth • Why the science does not support the idea that seed oils cause inflammation • The difference between acute and chronic inflammation, and why parents are often confused about what inflammation actually is • What decades of cardiovascular research tells us about vegetable oils and heart health • Why there is still no RDA for essential fatty acids and what that gap means for your family • How to think critically about nutrition claims on social media, especially ones that lead with fear Dr. Belury also shares what the adult research on linoleic acid and metabolic health may suggest for children with obesity, and why pediatric-specific studies in this area are so urgently needed. This is not a conversation about what oil to buy. It is a conversation about how to think clearly when you are surrounded by conflicting information and you just want to feed your kids well.

Protein bars in the lunchbox. Protein powder in the smoothie. Protein added to everything from waffles to mac and cheese. If it feels like protein is suddenly everywhere! You're not imagining it. In this episode, I'm pushing back on the idea that more protein is automatically better for kids, walking through what the RDA actually recommends, what newer research on "optimal" protein intake really means, and the research-backed downsides of overdoing it, especially for younger kids. I also draw a clear line for families navigating severe picky eating, ARFID, or an eating disorder, where the real concern is too little protein, not too much. I'll share a story from my practice that shows exactly how this trend can backfire, and what I want you to know before you reach for another scoop.

Summer should feel like a break. But for parents of kids between nine and fourteen, it often quietly unravels everything that kept their child healthy during the school year. Sleep shifts later. Breakfast gets skipped. Screens fill the hours. Movement drops off. And by August, you're wondering how things got so far off track. In this episode, I walk through what the research actually shows about what happens to children's health over the summer break, why tweens are especially vulnerable, and what one structural change can make a meaningful difference before the drift sets in. If you want to go deeper, I'm also hosting a free live webinar in June where I walk parents through a complete summer health framework. The registration link is in the show notes.

Nutrition advice for kids can feel overwhelming right now. In this episode, pediatric dietitian Jill Castle breaks down popular nutrition trends like seed oils, sugar, protein obsession, clean eating, and the Dirty Dozen list. She explains what parents actually need to know, what's worth paying attention to, and how to support a child's health without creating fear or rigid food rules.

What if the way we feel about our child's body matters more than anything we say? In this powerful conversation, I'm joined by body image psychotherapist Zoë Bisbing to unpack what body image really is—and how it quietly develops in childhood. We talk about the subtle, often unintentional ways parents influence their child's relationship with their body, and why even well-meaning efforts to "help" can sometimes backfire. You'll learn: What body image actually is (and why it's more than appearance) The difference between body positivity and body neutrality Early signs your child may be struggling with body image Why some children are more vulnerable than others How parental "vibe" around food and bodies shapes kids more than words What to do if your child says, "I hate my body" When to seek professional support—and what therapy looks like We also explore a powerful idea: that supporting your child's body image often starts with your own awareness, beliefs, and healing. This episode will help you create a home where kids feel safe, respected, and supported in their bodies—no matter their size.
