Headlines about children and GLP-1 medications have been coming fast this fall: more prescriptions for kids under 12, new trial results in children as young as 6, the World Health Organization's first guidelines on childhood obesity, and new concerns about nutrition and misuse. 
In this episode, pediatric dietitian Jill Castle walks parents through what the latest research is showing. 

You'll hear: 
•    where the AAP and WHO stand 
•    why many children on GLP-1s aren't getting nutrition support 
•    which nutrients matter most for a growing child
•    what to know about misuse and eating disorders 
•    the questions to ask your child's doctor 

Whether or not medication is part of your child's care, you'll leave with a clear picture of the foundation every child needs to thrive.

Halloween candy looks different this year. Dye-free M&M's, Skittles, and Starburst have arrived, low sugar and protein candy are cropping up everywhere, and parents are asking a new question: which candy is okay for my child?

In this episode, pediatric dietitian Jill Castle explains what has changed in the candy aisle, what the research says about food dyes and children's behavior, and why low sugar candy can lead to a stomachache. She also explains why sorting candy into good and bad can backfire, and shares a Halloween candy plan for kids that covers the weeks before, the night itself, and the leftovers.

In this episode:

•    Is dye-free candy better for kids?

•    Do food dyes cause hyperactivity in children?

•    Is low sugar or sugar free candy okay for kids?

•    Is protein candy a healthier choice?

•    Why labeling candy as good or bad can make kids want it more

•    How to handle Halloween night, from dinner to the candy sort

•    Candy guidelines for ages 5 to 8 and ages 9 to 14

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.

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.

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

The first week of school, the lunchbox is packed the night before and everything feels manageable. By week two, most of us are scrambling at seven in the morning wondering how we lost the thread so fast.

In this episode, pediatric dietitian Jill Castle shares the simple lunch framework she used with her own four kids and still walks parents through in practice today, along with a practical approach to after-school snacks and dinner timing for school-aged kids ages five to fourteen.

No complicated meal plans, no pressure for variety every single day. Just a realistic, repeatable rhythm that holds up in a real family's week.

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.

If you have a daughter who is heading into puberty or is already in the middle of it, this episode is one you will want to save.

Jill Castle sits down with Dr. Melisa Holmes, board-certified OB-GYN, co-founder of Girlology, and co-author of Youology: A Puberty Guide for Everybody. With more than 25 years of clinical experience in pediatric and adolescent gynecology, Dr. Holmes brings both the facts and the warmth that parents need when navigating this major chapter of their daughter's development.

In this conversation, you will learn:

• What puberty actually involves beyond breasts and periods, and why the timeline matters
• Why puberty is starting earlier in girls, and what is driving that trend
• How earlier puberty affects body image, peer relationships, and emotional development
• Why a period is a vital sign, and what to watch for when it stops or never shows up
• What girls should know before their first period, and how to have that conversation
• The connection between nutrition, bone health, and the menstrual cycle
• What to do if your daughter has painful periods, and when to seek care
• The truth about hormones, mood, and the myths that keep circulating
• How to find an adolescent and pediatric gynecologist

Dr. Holmes also addresses the impact of GLP-1 medications and the current cultural pressure around thinness, how to be your daughter's most trusted source of information, and three specific things parents can do right now to support a girl through puberty.

Whether your daughter is nine or fifteen, this episode gives you the foundation to talk openly, stay calm, and show up as the steady presence she needs.

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.

In this episode, I'm joined by Dani Lebovitz, co-author of Food Positivity, to explore why emotional safety at the table matters more than food rules—and what actually helps kids build trust with eating.

Most parents don't mean to shame their kids about food — but it happens more often than we realize. In this episode, Jill Castle breaks down the subtle ways food shame shows up at home, why it backfires, and how parents can shift toward supportive, emotionally safe feeding practices that help kids thrive.

When picky eating is extreme, it's rarely just about the food. Pediatric dietitian Katharine Jeffcoat explains how anxiety and sensory challenges impact eating, what helps beyond nutrition, and how to reduce pressure at the table—plus a simple "food science" approach to support progress.
