5 Health Benefits of Red Wine

You might not need an excuse for a glass of red wine but in case you do, here are five health benefits according to experts.

“Red wine contains antioxidants, particularly polyphenols provided by the grapes,” says Gabby Geerts, a registered dietitian at Green Chef. “Polyphenols have been shown to improve heart function and blood pressure, thus reducing the risk of cardiovascular disease.”

You have to stop sipping after a five-ounce glass in order to get that wellness boost. Otherwise, Geerts says, you’ll miss out on the healthy perks—and increase your risk of being seriously hungover the next day.

So, keep in mind that a little glass is all you need to score these massive, science-backed benefits.

More fun facts about the additional benefits of red wine.

1. It could prevent cavities

In a 2014 study published in the Journal of Agricultural and Food Chemistryresearchers found that red wine killed more cavity-causing bacteria than water spiked with alcohol, such as what is found in mouthwash.

2. It might keep your allergies in check

In a 2019 review of nearly 80 studies published in the journal Diseases, researchers suggest that flavonoids, an antioxidant found in red wine, could reduce allergy and asthma symptoms. More research is needed to confirm these findings, but it’s promising.

3. It could delay the onset of Alzheimer’s and Parkinson’s disease

In a study from 2017, researchers added wine-derived human gut metabolites—or the substance formed after your body digests wine and is found in feces—to deteriorating neurological cells. Then, something unexpected happened: the metabolites kept the cells from dying.

4. It could reduce your risk of depression

While heavy drinking has been widely associated with mental health issues, keeping your wine intake between two and seven five-ounce glasses a week might actually decrease your chances of struggling, according to a 2013 study published in the journal BMC Medicine.

5. It can help keep your blood sugar in check if you have Type 2 Diabetes

In a 2015 study published in the journal Annals of Internal Medicine, scientists assigned 224 patients with Type 2 diabetes to one of three groups. The first group was instructed to drink five ounces of red wine with dinner every night for two years. The second had to drink five ounces of white wine. The last group drank mineral water. By the end of the study, researchers found that the wine drinkers had better blood sugar control than those sticking to water. Plus, the red wine group improved their cholesterol levels.
