Emptying your wine rack faster than you’d like?

Clinq investigates the health benefits (if any) of drinking red wine regularly and in moderation.

We’ve all heard it before and we tell ourselves this while pouring a glass of red after a long day at work, but do the benefits of wine really outweigh the health concerns associated with alcohol consumption? This is definitely a topic close to my heart, when I’ve found myself reaching for that bottle of red more often than I’d like, but compared to my twenties and early thirties, my weekly overall intake is less and binge drinking is a much rarer occurrence.

So let’s take a look at what chemicals in wine, particularly red, reportedly have these health benefits and how they work.

Wine contains antioxidants; we’ve all heard of antioxidants, but do we know what they are and why they can be beneficial? Antioxidants are molecules found in certain foods that can help prevent damage to your body’s cells caused by an overload of ‘free radicals’. Free radicals are the result of the natural oxidation process within the human body, and although we need a certain amount of free radicals to function effectively, too many cause irreversible damage and can lead to certain diseases, including heart disease, liver disease, Alzheimer’s disease and some cancers. Antioxidants work by inhibiting the oxidization process, therefore keeping the number of free radicals under control.

Antioxidants can be broken down into 3 groups:

  • Carotenoids (plant pigments found in red, yellow and orange fruits and vegetables)
  • Allyl sulfides (found in garlic and onions)
  • Polyphenols (also known as phenolics)

The last group, Polyphenols or phenolics are the antioxidant group that are predominantly found in red wine, and this is because the skin of red grapes is a great source of these antioxidants (as well as peanuts and berries).

The two main polyphenols found in wine are quercetin and resveratrol, and there are many medical studies and research to show that these compounds help to:

  • Reduce inflammation (contributing factor to heart disease)
  • Reduce formation of plaque build-up in arteries (contributing factor to heart disease and Alzheimer’s).
  • Lower insulin resistance (high insulin resistance is linked to type 2 diabetes)

In fact, the benefits of quercetin and resveratrol don’t stop there and are said to play a part in minimising susceptibility to a number of other diseases and illnesses too;

  • Reduces risk of a number of cancers; there is much new research to show that resveratrol is a cancer inhibiting compound; helping to reduce precursor cancer inflammation, attacking several stages of the cancer process and even killing cancerous cells. However, there have been limited studies on humans to date and is by no means a sure way of preventing cancer. Dose amounts are unclear and effectiveness varies with genetics.
  • Reduces risk of dementia; moderate drinkers are 23% less likely to develop dementia, according to researchers at Loyola University Medical Center (USA).
  • Reduces risk of liver disease; drinking wine can reduce your risk of non-alcoholic fatty liver disease by half. It has to be wine though according to a US School of Medicine; beer and hard liquor can actually increase the risk by more than four times. (Moderation is key here; too much of any alcohol can cause alcoholic fatty liver disease.)
  • Increases omega-3 fatty acid levels; you could eat oily fish, but as far as alcoholic drinks go, wine is best for raising omega-3 levels, according to a European study and this help protects against coronary heart disease.
  • Reduces risk of blindness; polyphenol resveratrol can stop blood vessel growth in the eye; the cause of diabetic retinopathy and age-related blindness, according to USA researchers.
  • Monks_drinking wineSlows the ageing process; monks have believed for over a thousand years in wine’s anti-ageing properties, and now medical researchers have confirmed that red wine’s magical compound resveratrol is definitely linked to increased health and a longer life span.
  • Reduces the risk of depression; moderation is the key here of course, but a Spanish study found that men and women who drank two to seven glasses of wine each week were less likely to be diagnosed with depression than those that abstained. However, those that drank more than seven glasses per week were found to be at greater risk of developing depression, so keep an eye on your intake.
  • Protects from sunburn; scientists from Barcelona found that drinking wine can help to lessen the effects of UV (ultraviolet) rays and protect you from severe sunburn. That’s because those antioxidants inhibit the oxidation process which is triggered when UV rays hit human skin. We wouldn’t recommend relying on your wine consumption for this though, sunscreen should definitely still be applied (particularly in Australia!)
  • Increases sex drive; of course, alcohol can have a habit of bringing two people together, but an Italian study showed that women who drank more than two glasses on a daily basis had a higher sex drive than teetotallers, and testosterone levels in men were also increased after wine. In summary, red wine makes people horny! (It’s best to stick to a couple of glasses however, because research also shows that too much alcohol is likely to cause your libido to flop and bring about the other problems associated with excessive alcohol consumption)


I’m sure you’d agree that this is quite an impressive list, however, let’s point out that you would also get the same benefits from eating red grapes instead of drinking wine, but we’ll let you decide which you’d prefer… And to be more specific, in general, the darker the wine, the higher the antioxidant content, although cool climate pinot noirs also feature alongside your cabernet sav’s and shiraz grapes at the top of polyphenol content list.


Wine bottlesThe most important point to keep in mind whilst reading this article is that these benefits are only realized when drinking wine in moderation. From our research, the amount of red wine that can be consumed safely is between two to seven glasses of wine per week or a maximum of 14 units. It’s also important to note that this consumption should be spread out over the week (at least 3 days) and not guzzled all in one night! It’s suggested to have at least a couple of wine/alcohol-free days throughout the week, and of course this should be balanced out with a healthy diet and exercise.

The health risks associated with excessive alcohol consumption are very real and can override all of the above benefits. Despite moderate wine intake decreasing the risk of fatty liver disease, high levels of consumption can have the opposite effect. Your liver performs many important functions within your body, but regular heavy drinking stops it from doing its vital work and affects its ability to function. Drinking heavily or excessively can cause Alcoholic Hepatitis (inflamed liver), which may result in liver failure and death, and women are generally more susceptible to liver damage than men. The condition is reversible if you stop drinking, but continued misuse of alcohol can cause permanent damage and scarring, increasing your risk of developing liver cancer.

And liver disease is not the only concern; excessive drinking causes disruption to sleep, affects your judgement and can impact nutrition by inhibiting absorption of certain nutrients. This can make you more vulnerable to heart disorders, including high blood pressure and stroke. Binge drinking is especially harmful and can damage the brain. Regular heavy drinking is associated with a wide range of other health problems from liver disease to menstrual problems, nerve and muscle damage, psychiatric problems and cancers of the mouth, larynx or oesophagus. I’m sure you’re agree; a much more frightening list, and something to keep in mind when you go on your next night out.

To be aware of how many units of alcohol are in a standard 150ml of wine, check out the below table based on the alcohol by volume (abv) percentage of the wine:

  • 9% abv = 1.2units
  • 10% abv = 1.5 units
  • 11% abv = 1.65 units
  • 12% abv = 1.8 units
  • 13% abv = 1.95 units
  • 14% abv = 2.1 units


In summary, a glass or two of red wine throughout the week does supply you with the antioxidants linked to reducing the risk of heart disease, type 2 diabetes and some cancers, however, wine isn’t the only source of these antioxidants and they could be sourced from a wine-free diet. What we are trying to say, is that you don’t have to beat yourself up if you do have a glass or two on a regular basis, just don’t over-do and you’ll be on your way to a long, healthy life. Keep in mind that wine isn’t a replacement for a healthy diet and regular exercise, and it certainly doesn’t count as one of your five-a-day (we checked!).
