Health Effects of Beer

Beer is the third most popular drink in the world, ranking only behind water and tea, and is the alcoholic beverage of choice for most drinkers.

The industry ranges from an average person and their home-brew kit, through to huge multinational corporations. In 2006, beer production companies earned more than $294 billion USD.

The Chinese are the world's biggest beer drinkers, 45 billion liters were downed in 2010, outranking American, Japanese and German beer drinkers - all countries with a strong beer-loving reputation.

What is beer?

A German would say: it is a mixture of malted barley, hops, yeast and water with no other additives allowed, except maybe sugar. In fact, you can only use the word 'beer' in Germany to describe such an alcoholic drink - it is mandated by law!1

However, beer may mean any alcoholic drink made from the following ingredients:

  • water
  • a starch source, such as malted or non-malted grains
  • yeast for fermentation
  • plant-based flavoring agents such as hops, wormwood, ginger, berries, etc.

It may also contain sugar, or additives to remove the cloudiness of the liquid (clarifying agents).

The alcohol content is usually between 4-6%. However, it can be raised above 40% using freeze distillation methods.


Beer and health

But what about the health effects?

Over-consumption of anything has negative effects. Until recently, the negative image of drinking too much had a lot of exposure, with its associated beer bellies, increased aggression, and pounding hangovers.

Recent research is showing there are some positives to drinking beer in moderation, suggesting that 1 standard drink, 3-4 times per week may have health benefits.

Positive health effects

A low-level intake of beer, 1-2 standard drinks (350ml / 12 oz) ,has been shown in a wide range of studies to have positive effect on health.

Nutrients in a 350ml can of average beer

% Daily Value
Vitamin B6

The vitamin B and antioxidants in beer contribute to a healthy balanced diet.2

Other nutrients may be present, depending on the ingredients used in and the method of brewing.

Because of the antioxidant properties of alcohol, beer can protect against the following illnesses:

  • heart disease and heart attacks3
  • strokes4
  • gallstones5
  • kidney stones6

Drinking a small amount regularly, contributes to better bone density, preventing or delaying osteoporosis.7

It is also associated with a reduced risk of rheumatoid arthritis and can improve the immune system of healthy people.8,9


It may initially help with the fear of social situations, by relaxing tension and slowing the brain's processing of panic signals.

Reducing cholesterol

A moderate intake has been shown to reduce the bad cholesterol that thickens arteries, and also reduces cholesterol in the liver (possibly due to the ethanol content).

The bitter components raise the good HDL cholesterol, responsible for cleaning the bloodstream of the bad cholesterol. 17,18

Folk medicine

A popular folk remedy against insomnia is to drink a warm beer before sleeping, to relax and slow the nervous system.

Hops can be found in some herbal tea blends combating insomnia.

Negative health effects

The negative health effects are almost entirely due to chronic excessive drinking.

Drinking too much, too often, will cause the diseases that drinking a little beer seems to prevent!

Beer in language

Liver damage

Drinking more than four standard drinks in one day (350ml / 12 oz of beer), will trigger inflammation in the liver.

Long term heavy drinkers have a high risk developing liver disease: fatty liver (steatosis), alcoholic hepatitis, and eventually cirrhosis.10

The good news is that much of the early damage can be repaired by complete abstinence from alcohol.

How beer affects the brain

Even a small amount will slow down signal processing from the nervous system. Short term visual memory, depth perception and learning capabilities are all impaired with a few drinks.11

A moderate intake was shown to decrease verbal ability in elderly subjects.12

Adolescent drinkers can more easily damage their brain function and learning capabilities, because their brains are still developing. Alcohol upsets their hormonal balance, and stops the healthy development of organs, including their reproductive system.13

Over time, drinking heavily damages short and long term memory functions. Drinkers are unable to recall their intentions and plans, and have trouble learning.

Heavy drinkers are also more likely to suffer from insomnia and depression. The risk of strokes is increased, and eventually, alcohol withdrawal seizures and tremors may develop.

Unfortunately, this damage is not reversible.

Elsewhere in the body

Heavy drinkers are at risk of developing a number of forms of cancer, especially liver and colorectal cancers.14 In fact, various cancer bodies around the world have categorized alcohol as a known carcinogen.

Excessive alcohol intake has been linked to the following illnesses:

  • skin disorders including hives, psoriasis and rosacea.
  • gout, leading to arthritis.
  • stomach inflammation
  • osteoporosis
  • diabetes and pancreatitis

Perhaps T-rex Sue, who had severe gout and joint pain, ingested too much alcohol?

Health myths debunked

There are many baseless health claims both for and against beer drinking.

Beer alone is not what causes a beer belly. Eating and drinking too many calories is the primary cause of larger bellies.

It will also not help you lose weight! Even though alcohol increases the rate at which you burn calories, it makes you hungry.15

It is certainly not a meal in a bottle as it is lacking most of the healthy nutrients that make up a balanced meal, even though it has a high calorie count.

While red wine can help prevent common colds, beer has no effect.16 Although alcohol of any type doesn't shorten the infection time, it may help you relax and manage the symptoms more easily.

Does it cause brain damage?

Perhaps it could if you hit someone over the head with a full bottle!

Mythbusters proved in their Bottle Bash episode, a full long-neck beer bottle, used as a weapon, can result in severe concussion, brain trauma and skull fractures. Not to mention the glass cutting into the scalp! Ow!

Beer myth impact

Which beer myth are you most upset isn't true?

  • Beer bellies caused by beer.
  • Weight loss with beer.
  • Beer as a cold remedy.
  • Beer as a nutritional meal.
  • I already knew all of these were false!

When my mom was younger, she suffered from numerous kidney and bladder infections. Her doctor always suggested to go home and drink a beer. It was pure torture for her because she has always hated the taste. But she did say it helped her. Great job with this most informative hub - voted up!

I heard a fascinating claim in my international marketing class about a major Guinness marketing campaign during the 1930s which claimed that Guinness is "good for health" - and not only that, good for breastfeeding mothers to enhance breastmilk production! Guinness has stopped claiming that it's good for your health a long time ago but the connection with Guinness being good for nursing mothers still lingers and some women think it's true.

I've read somewhere that if you lack green leafy veggies in your diet you can drink beer instead. Of course, it should be taken in moderation. Anything in excess is bad for your health.

Voted up and useful.

Does excsessive beer drinking affect cholesterol?

Interesting article and well referenced. I hate beer but grew up around it and lots of beer alcoholics. The smell of it makes me ill. But I have to say, I have enjoyed on a few occasions some of the stronger beers, ales, whatever you call them.

nifwlseirff 3 years ago from Leipzig, Germany Author

Thanks lambservant! I went hunting specifically for beer and cholesterol research - seems it actually improves cholesterol! In moderation it reduces liver and heart cholesterol (the bad stuff), and increases HDL cholesterol (the good stuff). Added to the article - thanks again!

Cool! great job and very informative. I want to ask something, I have a friend that told me about excessive beer drinking. If you drink a lot, drinking lot water in the morning would minimize consequences. Is that true? medically speaking?

nifwlseirff profile image

nifwlseirff 3 years ago from Leipzig, Germany Author

Hi PaoloJpm! The alcohol in beer is metabolized by the liver while you sleep, over a period of 4-8 hours, so adding water the morning after drinking too much, won't help. Of course, it will help to replace the water in your body that was lost thanks to beer's diuretic properties!
