Estimated Reading Time: 4 minutesWhen your child is melting down over the smallest thing, it’s easy to wonder if you’re missing something big. So many parents never realize that what their child eats can directly impact anxiety, focus, and emotional control.In this episode, I break down the three foods that make anxiety worse and the simple swaps that help kids feel calmer, more regulated, and more in control.

Why does my child crash after eating sugary snacks?

Sugar and processed carbs can send a dysregulated child into a full spiral. These foods spike blood sugar, then cause a hard crash that fuels irritability and anxious behavior. They also disrupt calming neurotransmitters like serotonin and GABA.A parent recently told me that after swapping cereal and juice for turkey roll ups, her son was noticeably calmer by lunchtime. Small change, big shift.Try this instead:

• Pair protein and healthy fats with carbs to keep blood sugar stable
• Examples: yogurt with berries, apple with nut butter, smoothies with real fruit
• Notice mood shifts within hours

What to avoid:

• Sugary cereals
• Juice boxes
• Processed snacks made with white flour

Are food dyes and additives making my child’s anxiety worse?

Parents are searching for this every day, and yes, dyes like Red 40 and additives like MSG or aspartame can overstimulate the nervous system. Sensitive kids often react with poor sleep, irritability, or impulsivity.One mom shared that her daughter was out of control for days after a single dye filled candy. Removing dyes led to calmer days and fewer emotional eruptions.Try this instead:

• Whole food snacks like freeze dried fruit
• Naturally colored options
• Simple trail mix with seeds, coconut flakes, and a small amount of dark chocolate

Avoid:

• Bright neon snacks
• Diet sodas
• Anything with an ingredient list longer than your grocery receipt

Can gluten really increase anxiety symptoms in kids?

For some children, absolutely. Gluten in the US is often sprayed with pesticides that irritate the gut and trigger inflammation. Since the gut and brain are tightly connected, that inflammation can increase anxiety and even panic.Dr. Roseann shared how her nephew’s anxiety improved once they discovered he had celiac disease.Swaps to try:

• Brown rice
• Coconut wraps
• Almond flour crackers

Signs gluten may be a trigger:

• Anxiety after meals
• Frequent stomachaches
• Mood swings or emotional crashes

Can diet changes really reduce my child’s anxiety?

Yes, and it doesn’t require perfection. Removing even one trigger for 30 days can create a big difference in mood, sleep, and focus. The goal is to calm the brain first with consistent whole food choices.Start with:

• Whole foods
• Healthy fats
• Protein
• Complex carbs
