Healthy Foods That Spike Blood Sugar in Diabetes- What’s Missing From the Plate (and What to Add Instead)
As a parent of a child or teenager living with Type 1 Diabetes, or living with T1D yourself, you quickly become a food detective. Every blood sugar spike prompts the same questions: What caused it? Did I carb count correctly? Was it the food, the timing, the activity, too much of something?
The advice often sounds the same: remove, limit or avoid certain foods. However, for many toddlers, children, and teenagers living with diabetes, the real issue isn’t what’s on the plate- it’s what’s missing from it.
Many foods that are considered healthy can cause blood sugar spikes when eaten on their own. Not because they’re “bad,” but because they lack the protein, fat, or fibre needed to slow digestion and support steadier glucose levels. In diabetes management, better blood sugar control often doesn’t come from taking food away- it comes from adding the right foods alongside it.
By learning how to build balanced meals using simple food pairings, families and those with T1D can improve post-meal glucose levels, reduce spikes and crashes, and create meals that are more predictable, satisfying, and sustainable- especially for growing toddlers, children, and teens.
Why Adding to the Plate Improves Blood Sugar Control
Carbohydrates raise blood sugar, and they should. Children need carbohydrates for growth, learning and energy. Problems arise when carbohydrates are eaten without enough protein, fat, or fibre to slow digestion.
Adding these nutrients:
Slows glucose absorption
Reduces sharp spikes and crashes
Supports more predictable insulin timing
Improves time in range
Balanced meals support not only blood sugar but also energy levels, mood, and long-term confidence around food.
1. Fruit: Nutritious, but Fast-Acting on Its Own
Fruit contains natural sugars and digests quickly when eaten alone.

6. Smoothies: Nutritious, but Easy to Spike Blood Sugar
Blended foods digest faster than whole foods.

What to add instead

Chicken, cheese, quinoa
Teens
Protein, grains, healthy fats
Final Thoughts: Better Blood Sugar Control Comes from Adding, Not Avoiding
For toddlers, children, and teenagers living with diabetes, better glucose control rarely comes from restriction. It comes from understanding what’s missing from the plate and adding it back in.
When protein, fat, and fibre are added alongside carbohydrates:
Digestion slows
Blood sugar becomes more predictable
Meals feel more satisfying and sustainable
Instead of asking, “Should we avoid this food?”
Ask, “What can we add to make this meal work better?”
Because in diabetes management, balance- not removal- is what builds steadier blood sugar and healthier relationships with food.
