Coffee (Espresso Brewed) (100 G) and Oat Milk (100 Ml)

Use a smaller amount of oat milk, or switch to unsweetened almond milk or unsweetened soy milk with no added sugar.

Avoid flavored syrups, sweetened creamers, and barista blends that often contain added sugars.

Have the espresso with or after a balanced meal rather than on an empty stomach; include protein and fiber such as eggs, plain Greek yogurt, or chia seeds.

If you want a snack with coffee, choose a small handful of almonds or walnuts instead of pastries or cereal-based snacks.

Try drinking the coffee more slowly and limit it to a single serving, since caffeine can raise glucose in some people.

Check your response with your usual glucose-monitoring method after trying one change at a time; caffeine sensitivity and oat-milk formulations vary.
