Coffee, black, 1 cup (1 serving)

Drink the coffee plain, without sugar, syrups, sweetened creamers, or flavored milk additives.

Have coffee with or after a balanced meal rather than on an empty stomach, especially if you notice caffeine raises your glucose.

Choose decaf or half-caf coffee to see whether reducing caffeine lessens the rise.

Pair coffee with a protein- and fiber-rich snack such as plain Greek yogurt with berries, a small handful of nuts, or hummus with non-starchy vegetables.

Add unsweetened milk or an unsweetened fortified soy beverage instead of sweetened creamers if you prefer a lighter coffee.

Take a 10–15 minute easy walk after coffee or your accompanying meal to help moderate the glucose response.
