If You Had to Choose One Alcohol Type, Let It Be Red Wine

Edited By: Natalia Jones

The vast majority of alcoholic beverages do more harm than good for our health, particularly our brains and our digestive systems, but are all alcohol varieties made equal? It all depends on the dosage, of course, as a lot of any kind of food or drink is unhealthy, but if consumed in moderation, the alcoholic beverage of choice is red wine. But don’t take it from us, as there is plenty of scientific evidence to back this claim.

Previous studies have shown that red wine is stimulating for the brain and outlined many other known health benefits of red wine. But the most recent one of the bunch, an article published in late August 2019, in the journal ‘Gastroenterology’ suggests that the polyphenol antioxidants in red wine may promote the long-term health of one’s digestive system if consumed in moderation.

What Effect Does Red Wine Have on the Digestive System?

The study was conducted at King’s College London in the United Kingdom, and it observed the diversity of gut microbiome and other digestive health markers in 916 female twins. The goal of the study was to research the effect of different types of alcohol, specifically red and white wine, beer, cider, and strong drinks had on the digestive system. The researchers looked at 3 separate cohorts of participants (those from the UK, the Netherlands, and the USA), and controlled for possible confounds, such as age, diet, and socioeconomic status, all of which adds credibility to their findings.

As for the findings themselves, the study concluded that red wine was the only alcoholic beverage associated with an increased number of different beneficial gut bacteria, as well as a smaller likelihood of obesity and lower cholesterol levels. All in all, drinking red wine was found to have a beneficial long-term effect on digestive health and the phytochemicals responsible for these beneficial effects were suggested to be polyphenols.

The authors suggest that the polyphenols acted as nourishment for the different gut bacteria and promoted their growth. Apart from promoting gut health, polyphenols are known for being capable of lowering one’s risk of the following conditions:

The findings of this and previous studies convinced us that drinking a little red wine is beneficial for our overall health, but how much red wine are we talking about, exactly? Although previous estimates have mentioned quantities like 1 or half a glass daily, the authors of the present study state that not much is needed, with only one glass once every 2 weeks being able to yield the beneficial health effects.

Red wine and resveratrol: Good for your heart?

Resveratrol might be a key ingredient that makes red wine heart healthy. Learn the facts — and hype — about red wine and how it affects your heart.

By Mayo Clinic Staff

Red wine, in moderation, has long been thought of as heart healthy. The alcohol and certain substances in red wine called antioxidants may help prevent coronary artery disease, the condition that leads to heart attacks.

Any links between red wine and fewer heart attacks aren’t completely understood. But part of the benefit might be that antioxidants in red wine may increase levels of high-density lipoprotein (HDL) cholesterol (the „good“ cholesterol) and protect against cholesterol buildup.

Doctors don’t recommend that you start drinking alcohol for heart benefits, especially if you have a family history of alcohol addiction. Too much alcohol can have many harmful effects on your body.

But if you already enjoy a glass of red wine with your evening meal, drinking it in moderation appears to help your heart.

How is red wine heart healthy?

Antioxidants in red wine called polyphenols may help protect the lining of blood vessels in your heart. A polyphenol called resveratrol is one substance in red wine that’s gotten attention for its health benefits.

Alcohol itself may have some protective effects when consumed in moderation.

Resveratrol in red wine

Resveratrol might help prevent damage to blood vessels, reduce low-density lipoprotein (LDL) cholesterol (the „bad“ cholesterol) and prevent blood clots.

However, studies on resveratrol are mixed. Some research shows that resveratrol could be linked to a lower risk of inflammation and blood clotting, which can lower your risk of heart disease. But other studies found no benefits from resveratrol in preventing heart disease.

More research is needed to determine if resveratrol lowers the risk of inflammation and blood clotting.

Resveratrol in grapes, supplements and other foods

The resveratrol in red wine comes from the skin of grapes used to make wine. Because red wine is fermented with grape skins longer than white wine, red wine contains more resveratrol.

Simply eating grapes or drinking grape juice might be a way to get resveratrol without drinking alcohol. Red and purple grape juices may have some of the same heart-healthy benefits of red wine.

Peanuts, blueberries and cranberries also contain some resveratrol. It’s not yet known how beneficial eating grapes or other foods might be compared with drinking red wine when it comes to promoting heart health. The amount of resveratrol in food and red wine can vary widely.

Resveratrol supplements also are available. Researchers haven’t found any harm in taking resveratrol supplements, but your body can’t absorb most of the resveratrol in supplements.

How might alcohol help the heart?

There’s still no clear evidence that beer, white wine or liquor aren’t any better than red wine for heart health.

Various studies have shown that moderate amounts of all types of alcohol benefit your heart, not just alcohol found in red wine. It’s thought that alcohol:

Drink in moderation — or not at all

The potential heart-healthy benefits of red wine and other alcoholic drinks look promising. Those who drink moderate amounts of alcohol, including red wine, seem to have a lower risk of heart disease.

However, it’s important to understand that studies comparing moderate drinkers to nondrinkers might overestimate the benefits of moderate drinking because nondrinkers might already have health problems.

More research is needed before we know whether red wine is better for your heart than other forms of alcohol, such as beer or spirits.

The American Heart Association and National Heart, Lung, and Blood Institute don’t recommend that you start drinking alcohol just to prevent heart disease. Alcohol can be addictive and can cause or worsen other health problems.

Drinking too much alcohol increases your risk of:

Avoid alcohol completely if you:

If you have questions about the benefits and risks of alcohol, talk to your doctor about specific recommendations for you.

If you already drink red wine, do so in moderation. For healthy adults, that means:

Up to one drink a day for women of all ages.

Up to one drink a day for men older than age 65.

Up to two drinks a day for men age 65 and younger. The limit for men is higher because men generally weigh more than women and have more of an enzyme that metabolizes alcohol.

A drink is defined as:

12 ounces (355 milliliters) of beer

5 ounces (148 milliliters) of wine

1.5 ounces (44 milliliters) of 80-proof distilled spirits
