Oat milk: verdict by goal
The details
Blood sugar: Counterintuitive but real: even UNSWEETENED oat milk is Avoid here. Making it enzymatically breaks the oat starch into maltose, a fast sugar — so its glycemic index runs ~60+ (higher than cola's) with 'no added sugar' still on the label. The spike is from processing, not added sweetener. Swap → unsweetened almond, soy, or coconut milk.
How to choose: Skip even the unsweetened version — the maltose is baked in by processing. Unsweetened almond/soy/coconut are the swaps.
How to use it: Swap for unsweetened almond, soy, or coconut milk.
How to store: Fridge after opening.
Sensible portion: avoid, rarely
