DASH diet: Healthy eating to lower your blood pressure

DASH diet: Alcohol and caffeine

Drinking too much alcohol can increase blood pressure. The Dietary Guidelines for Americans recommends that men limit alcohol to no more than two drinks a day and women to one or less.

The DASH diet doesn't talk about caffeine. How caffeine affects blood pressure isn't clear. But caffeine can cause blood pressure to rise at least briefly.

If you have high blood pressure or if you think caffeine affects your blood pressure, think about cutting down. You might talk to your health care provider about caffeine.
