Cold brew (1 piece)

Choose plain, unsweetened cold brew; avoid sweetened syrups, flavored creamers, sweetened milks, and cold-foam toppings.

Have cold brew with or after a balanced meal rather than on an empty stomach; pair it with eggs, plain Greek yogurt, nuts, or avocado.

Try a smaller serving or dilute the cold brew with water or unsweetened milk, then assess whether your glucose response improves.

Reduce caffeine exposure by choosing half-caf or decaf cold brew, especially in the morning or during periods of stress or poor sleep.

Add a 10–20 minute easy walk after drinking it or after the accompanying meal.

Keep the timing and recipe consistent for several days, compare responses, and adjust one factor at a time; discuss persistent or large spikes with your clinician.
