Cofee (1 piece)

Choose plain black coffee or add a small amount of unsweetened milk; avoid sugar, syrups, flavored creamers, and sweetened plant milks.

Drink coffee with or after a balanced meal rather than on an empty stomach, especially if you notice a consistent rise.

Pair coffee with protein- and fiber-rich options such as eggs, plain Greek yogurt, nuts, or chia seeds instead of pastries or sweet breakfast foods.

Try a smaller serving, half-caf, or decaf; caffeine can raise glucose in some people even without added sugar.

Avoid coffee drinks that combine caffeine with high-carbohydrate ingredients, such as mochas, frappes, and sweetened cold brews.

Track your response by checking glucose before coffee and again about 1–2 hours afterward, then adjust the type, amount, and timing of coffee accordingly.
