Most people with diabetes can drink alcohol, including wine, as long as they do not have another medical condition that makes drinking unsafe.
Wine may even offer some protective health benefits in small quantities. However, alcohol dependence can be very dangerous for people with diabetes, as the complications of one condition can intensify those of the other.
This article explains the relationship between wine and diabetes and provides some other dietary tips for people with this condition.
Wine is a relatively low sugar drink, with both
Wine coolers (which contain juice) and other flavored wine drinks tend to be sweeter, and they often have a higher sugar and calorie content. In almost all cases, though, the sugar content of wine is unlikely to affect a person’s daily sugar intake significantly.
Alcohol is a relatively high calorie drink, particularly considering that it has no nutritional value. For example, a 5-oz serving of red wine contains about 128 calories. Drinking several glasses of wine each day can increase the number of calories a person consumes, potentially leading to weight gain.
Weight gain may increase the risk of certain diabetes complications. There is also
Sticking to relatively low calorie and low sugar red and white wines can help people minimize their sugar intake. Other wines may have a higher sugar content and more calories. A
A few studies suggest that red wine may offer some health benefits.
A 2011 study on rats, for example, found that daily red wine consumption had antioxidant effects that could reduce the risk of some diabetes complications. A
A 2014 cohort study of French women found a reduced risk of developing diabetes among individuals with overweight who consumed red wine.
Alcohol, including wine, may increase the risk of dangerously low blood sugar, even in people who are not taking insulin or other diabetes medications.
The liver releases glucose to help the body maintain a healthy blood sugar level. The liver also must break down alcohol. So when a person is drinking, the liver is less effective at releasing glucose when the body needs it.
The risk of alcohol-related low glucose is higher when a person:
- drinks on an empty stomach
- takes diabetes medication or insulin
- replaces a meal with alcohol
- drinks to excess
It takes about 1–1.5 hours for the liver to break down the alcohol in one drink. Until the body successfully metabolizes the alcohol, the risk of low blood glucose persists.
People with diabetes can reduce their risk of health complications by following a diabetes-friendly diet. The
- eating plenty of low glycemic index foods, such as whole wheat pasta and bread, milk, yogurt, and apples
- eating a high-fiber diet that includes foods such as whole grain bread, vegetables, and fruits, which can help lower blood glucose
- switching from eating three large meals a day to having more frequent, smaller meals
- eating plenty of lean proteins, such as chicken, turkey, and lentils
- reaching or maintaining a moderate body weight to reduce the risk of diabetes-related complications
People can take the following measures to drink more safely:
- stopping drinking after one or two drinks
- avoiding drinking on an empty stomach or after skipping a meal
- avoiding drinking if blood glucose is not well-controlled or the person has a history of negative reactions to alcohol
- eating food alongside drinking alcohol
- refraining from exercising while under the influence of alcohol, as exercise lowers blood sugar
Emergency help will be necessary if a person faints or experiences other symptoms of low blood glucose.
Most people with diabetes can safely drink alcohol in moderation. However, it is important that people monitor how alcohol makes them feel and stop drinking right away if they feel dizzy or weak.
People with alcohol use disorder or a history of binge drinking should contact a doctor about safe strategies for reducing or eliminating alcohol consumption.
