There are several benefits to drinking a glass of wine.
There are many antioxidant-rich foods and beverages, and wine is one of them.
Antioxidants are compounds that prevent cellular damage caused by inflammation and oxidative stress. Oxidative stress is a condition caused by an imbalance between antioxidants and unstable molecules called free radicals, which can damage your cells (2Trusted Source).
Grapes have high levels of polyphenols, which are antioxidants that have been shown to reduce oxidative stress and inflammation (3Trusted Source).
Because red wine grapes are higher in antioxidants than white grape varieties, drinking red wine may increase your blood antioxidant levels to a greater extent than drinking white (4Trusted Source).
In fact, one 2-week study in 40 adults found that consuming 13.5 ounces (400 ml) of red wine daily increased antioxidant status (2Trusted Source).
Higher antioxidant status is associated with a decreased risk of disease. For example, drinking red wine has been associated with a reduced risk of Alzheimer’s and Parkinson’s disease, which are associated with oxidative stress (3Trusted Source).
Wine contains compounds that have anti-inflammatory properties.
Chronic inflammation is harmful and may increase the risk of conditions such as heart disease, autoimmune disorders, and certain cancers. Therefore, it’s best to prevent this type of inflammation as much as possible (5Trusted Source).
Chronic inflammation can be reduced through diet, stress reduction, and exercise.
Many foods have the power to reduce inflammation, and wine is thought to be one of them.
One study in 4,461 adults demonstrated that moderate consumption of wine was linked to a reduced inflammatory response (7Trusted Source).
Participants in this study self-reported their alcohol intake. Those who consumed up to 1.4 ounces (40 grams) of alcohol per day experienced less inflammation than those who didn’t drink (7Trusted Source).
What’s more, in a study including 2,900 women, those who consumed a glass of wine daily had significantly reduced inflammatory markers compared with women who abstained from alcohol (8Trusted Source).
On the other hand, other research has found red wine to have a less dramatic effect.
A study in 87 adults of an average age of 50 found that drinking 5 ounces (150 ml) of red wine daily caused only slight reductions in inflammatory markers compared with abstaining from alcohol (9Trusted Source).
Although the research is promising, more studies are needed to better understand the anti-inflammatory benefits of wine.
Studies show that individuals who consume moderate amounts of wine have reduced rates of heart disease (10Trusted Source).
Some research suggests that drinking red wine may reduce blood pressure in people with high blood pressure, which may reduce the risk of heart disease (12Trusted Source).
Yet, other studies suggest that a daily glass of red wine does not reduce blood pressure in people with normal blood pressure or those who already have heart disease (13Trusted Source).
What’s more, wine may interact with medication that lowers blood pressure (14Trusted Source).
Whether moderate wine intake benefits heart health is up for debate as research in this area continues (16Trusted Source).
Drinking wine in moderation may also have other benefits:
