Beer Drinking: Healthy Habit Or Health Hazard?

Beer is one of the most popular alcoholic drinks worldwide. It is often viewed as empty calories, but it does contain some vitamins and minerals. The health effects of drinking beer are mixed, and depend on the amount consumed. While drinking a pint of beer a day may have some health benefits, such as improved heart health, stronger bones, and reduced dementia risk, heavy and binge drinking have the opposite effects. In addition, alcohol consumption can negatively impact sleep, weight loss, and digestive health.

May aid bone density

Beer has been linked to increased bone mineral density in both men and women. A 2021 review published in Nutrients found that drinking one beer per week was associated with a lower risk of hip fracture. The study also suggested that beer consumption may be linked to increased bone density.

The silicon content of beer is often cited as a reason for its positive effects on bone density. Silicon is a major constituent of beer, and it has been found to promote bone formation. A study published in the American Journal of Clinical Nutrition in 2009 found that men who consumed 1-2 beers per day had increased bone density compared to non-drinkers. Similarly, postmenopausal women who consumed more than 2 beers per day had significantly greater bone density. However, for men, consuming more than 2 beers per day was associated with lower bone density.

The phytoestrogen content of beer is also believed to contribute to its beneficial effects on bone density. Phytoestrogens are plant-based compounds that have similar effects to the hormone estrogen. A 2006 study found that the phytoestrogen 8-prenylnaringenin, isolated from hops, was effective in preventing menopausal symptoms in animals.

While beer may have positive effects on bone density, it is important to note that excessive alcohol consumption can have negative effects on overall health. The benefits of beer consumption should be weighed against the potential risks associated with alcohol intake.

May disrupt sleep

Alcohol can negatively impact sleep quality, even when consumed in light amounts during the day. While it may initially act as a sedative, helping you fall asleep faster, the intoxication of alcohol can affect your brain's long-term health and impair your sleep.

Alcohol can slow down your reflexes and affect your balance, memory, and sleep. It can also disrupt your brain's communication pathway and its ability to process information. As your body metabolizes alcohol, you may experience a rebound arousal, leading to fragmented and low-quality sleep later in the night. This can result in frequent wakings and a decreased amount of REM sleep, which is when most dreaming occurs.

The disruption to your sleep architecture caused by alcohol can leave you feeling tired the next day. Additionally, the diuretic effect of alcohol can increase your urge to urinate, further interrupting your sleep.

To minimize the impact of alcohol on your sleep, it is recommended to avoid consuming alcohol at least 3 hours before bedtime.

May slow weight loss

Drinking a pint of beer a day may slow down your weight loss. Firstly, beer is an "empty calorie" drink, providing almost no nutrients to your body. A 12-ounce can of beer contains almost 155 calories, and these calories are easily overconsumed as they are in liquid form. Secondly, alcohol is prioritised by the liver as a fuel source, meaning that the body's fat-burning process is slowed down. The liver can only handle a certain amount of alcohol, and drinking excessively can cause permanent damage. Thirdly, beer does not fill you up, so you will still have room in your stomach for a full meal after drinking. Finally, beer may negatively affect your sleep, and sleep deprivation is directly linked to weight gain and muscle loss.

May cause digestive issues

Alcohol can cause digestive issues, and beer is no exception. Firstly, alcohol is broken down in the stomach, promoting an increase in digestive juices. This can affect how the body breaks down nutrients. It can also irritate the gut, including the stomach, small intestine, and colon, where it is further broken down and absorbed. This can lead to inflammation in the lining of the intestines, impairing the gut's ability to absorb nutrients.

The speed at which food moves through the digestive system can also be affected by alcohol consumption. The body may be unable to absorb the normal amount of water back into the body, leading to loose, watery stools and diarrhoea. On the other hand, alcohol acts as a diuretic, causing the body to produce more urine than usual, which can lead to dehydration and constipation.

Additionally, alcohol can negatively alter the bacteria in the gut and permeate the lining of the intestine, leading to "leaky gut syndrome". This makes the body more susceptible to alcohol-related diseases, including alcoholic fatty liver disease.

However, it is important to note that some research suggests that the fermented compounds in beer could potentially benefit gut health.

May increase risk of chronic diseases

While drinking a pint of beer a day may not increase your risk of dying, according to a Canadian study, it may increase your risk of developing chronic diseases. Chronic diseases are long-term illnesses that persist over time and often develop slowly. Drinking a pint of beer every day can elevate your chances of experiencing specific chronic diseases.

Firstly, drinking a pint of beer daily can increase your risk of developing cardiovascular disease. While light to moderate drinking may reduce the chances of cardiovascular disease, heavy drinking increases this risk. Excessive alcohol consumption can lead to high blood pressure, stroke, heart failure, and cardiomyopathy, a disorder targeting the heart muscle.

Secondly, regular beer consumption is associated with an increased risk of specific cancers. Even at low levels, beer, like all alcoholic beverages, raises the likelihood of certain cancers, including mouth, throat, voice box, oesophagus, colon, rectum, liver, and breast cancer. The American Cancer Society estimates that alcohol consumption accounts for 6% of all cancers and 4% of cancer deaths in the United States.

Thirdly, drinking a pint of beer daily can contribute to liver disease. Alcoholic liver disease, such as fatty liver disease and sclerosis of the liver, can occur with excessive alcohol consumption. The toxin and carcinogen acetaldehyde, produced when alcohol is broken down in the liver, is particularly harmful.

Finally, drinking a pint of beer every day can elevate your risk of developing chronic diseases related to bone health and digestion. While some studies suggest that beer consumption may be linked to increased bone mineral density, excessive drinking can negatively impact bone health and contribute to osteoporosis. Additionally, alcohol can irritate the stomach lining, causing inflammation and digestive issues, including abdominal pain, bloating, and diarrhoea.
