Red wine (1 piece)

Drink red wine only with a balanced meal rather than on an empty stomach; include protein, healthy fats, and high-fiber vegetables.

Limit the serving size and sip slowly; avoid refills, since more alcohol can raise glucose later and disrupt overnight control.

Choose dry red wine instead of sweet, dessert, fortified, or flavored wines, which tend to contain more residual sugar.

Pair wine with options such as plain Greek yogurt dip, nuts, cheese, eggs, lentils, chickpeas, or non-starchy vegetables rather than bread, crackers, sweets, or sugary mixers.

Take an easy 10–20 minute walk after drinking or after your meal, if safe for you, to help muscles use circulating glucose.

Monitor your glucose response over the next several hours, because alcohol can sometimes cause delayed low glucose—especially if you use insulin or glucose-lowering medication.
