    Are Seed Oils in Baby Formula Safe? A Researcher Explains

    If you've scrolled social media lately, chances are you've seen someone call seed oils toxic, and that has a lot of parents second guessing the infant formula sitting in their pantry. In this episode, pediatric dietitian Jill Castle sits down with Dr. Corrie Whisner, an infant nutrition researcher at Arizona State University, to separate the science from the scare. They cover why fat is foundational in the first year of life, why seed oils show up in formula to provide fatty acids a baby cannot make on its own, how the FDA regulates every product on the shelf, and what actually matters the next time you're standing in the formula aisle trying to make a choice. If you've ever wondered whether you picked the right baby formula, this conversation is here to help you feel confident instead of confused.

    Oreogate: What a Viral Lunchbox Feud Teaches Us About Food Restriction

    A cookie ban in one family's lunchbox turned into a school-wide group chat feud, complete with trading, secret stashes, and a full-on parent showdown. It's a funny story, but it's also a near-perfect real-world example of what happens when a food gets fully restricted. In this episode, pediatric dietitian Jill Castle breaks down the research behind the forbidden fruit effect, why restriction tends to backfire and increase a child's preoccupation with a food, and what to do instead using the feeding and eating pillars of her Whole Child Healthy Model. If you've ever wondered why your "no" around a certain snack seems to make your child want it more, this episode gives you the science and a practical, non-shaming path forward.

    Fresh Food Isn't Always More Nutritious (with Jennie Norka)

    Frozen food gets a bad reputation it hasn't earned. If you've ever felt a flicker of guilt tossing a bag of frozen peas into dinner, or wondered whether a frozen entree is really as nutritious as something made from scratch, this episode is for you. I'm joined by Jennie Norka, MPH, Senior Director of Scientific and Regulatory Affairs at the American Frozen Food Institute, to walk through what's actually happening behind your freezer door. We take on five common myths, one at a time: that frozen food is less nutritious than fresh, that it's loaded with preservatives, that frozen meals are automatically unhealthy, and that reaching for frozen makes you a lazy parent. Jennie explains how flash freezing locks in nutrients at the moment of harvest, often preserving more nutrition than produce that's been sitting in your fridge for a week. We also get into label reading, a side-by-side comparison of frozen entrees versus homemade recipes, and one food safety detail every parent of a baby or toddler needs to hear about frozen vegetables. Whether you're feeding a family on a tight schedule, a tight budget, or both, you'll walk away with practical ways to build balanced meals using what's already sitting in your freezer aisle. In this episode: • Why the "fresh is always more nutritious" belief doesn't hold up • How individual quick freezing (IQF) actually protects nutrients and texture • What's really in a frozen meal, and how to read the label with confidence • A side-by-side comparison: frozen entrees vs. homemade recipes • The one food safety step every parent should know before serving frozen vegetables to a baby or toddler • Simple ways to build a balanced meal using frozen fruit, vegetables, and proteins • How frozen food can help stretch a grocery budget and cut down on food waste Resources mentioned: • The American Frozen Food Institute: frozenadvantage.org • Sign up for the Munch newsletter and more parent resources at thenourishedchild.com

    The Truth About Omega-6 Fats and Kids, with Researcher Dr. Martha Belury

    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.

    Does Your Child Need More Protein? What the Research Actually Says

    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.

    Why Summer is the Season Your Child's Health Quietly Slides

    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.

    Raising Kids with a Healthy Body Image (Without Pressure or Shame)

    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.
