I had a CGM:

- oatmeal + blueberries: moderate glucose spike

- oatmeal + blueberries + chia seeds: moderate glucose spike

- oatmeal + blueberries + ground flax seed: moderate glucose spike

- oatmeal + blueberries + protein powder: moderate glucose spike

- oatmeal + blueberries + protein powder + chia seeds: very minimal spike

In my case, it seems like carbs, proteins, and fats are all necessary to prevent a spike.
