Sparkling coffee (1 ml)

Choose an unsweetened sparkling coffee or cold-brew version; avoid added syrups, sugar, honey, sweetened creamers, and fruit juice mixers.

Have sparkling coffee with or after a balanced meal rather than on an empty stomach, especially one containing protein and healthy fat such as eggs, plain Greek yogurt, or nuts.

If you add milk, use an unsweetened option and keep the portion modest; avoid sweetened oat drinks and flavored creamers.

Reduce the serving size or dilute it with plain sparkling water, then sip it slowly instead of drinking it quickly.

Take a 10–20 minute easy walk after drinking it to help your muscles use circulating glucose.

Check the label for hidden carbohydrates and choose options with little or no added sugar; caffeine itself can raise glucose for some people, so consider a lower-caffeine or decaf sparkling coffee.
