Beer And Cholesterol: How Alcohol Affects Medication

Beer is a staple of the American diet, with 43% of Americans who drink alcohol preferring it over other alcoholic beverages. But what effect does it have on cholesterol? While beer doesn't contain any natural cholesterol, it can still impact your cholesterol levels. Beer contains carbohydrates and alcohol, which are substances that quickly raise triglyceride levels. Since triglycerides are part of the total cholesterol count, an increase in triglycerides means an increase in total cholesterol. Beer also contains cholesterol-binding sterols, but these are at such low levels that they have little impact on reducing cholesterol. While light to moderate alcohol intake may improve HDL (good) cholesterol, heavy drinking is consistently tied to negative health outcomes, including high LDL (bad) cholesterol, and an increased risk of heart disease.

Beer and cholesterol test interference

Beer is a popular alcoholic drink worldwide, but how does it affect cholesterol levels? And can it interfere with cholesterol tests?

Cholesterol is a waxy substance produced by the liver and found in certain foods, such as meat, eggs, and cheese. While cholesterol is essential for building cells and producing vitamins and hormones, high cholesterol can lead to clogged arteries and increase the risk of heart disease and stroke.

There are two types of cholesterol: low-density lipoprotein (LDL), known as "bad" cholesterol, which builds up in the arteries, and high-density lipoprotein (HDL), known as "good" cholesterol, which helps remove LDL cholesterol from the arteries.

When it comes to beer and cholesterol, the quantity and frequency of consumption have the most significant impact. Beer is high in carbohydrates and alcohol, which can affect cholesterol levels. While beer does not contain any natural cholesterol, it can raise triglyceride levels. Triglycerides are a type of fat that contributes to fatty buildup in the arteries, increasing the risk of diabetes, pancreatitis, and stroke.

Excessive alcohol consumption can also interfere with the liver's ability to manage cholesterol levels. The liver breaks down alcohol and reconstructs it as cholesterol and triglycerides, so the more you drink, the higher these levels rise. Therefore, heavy drinking is associated with high LDL cholesterol, high total cholesterol, and high triglyceride levels, all of which increase the risk of heart disease.

However, some studies suggest that light to moderate alcohol consumption may have a different effect. These studies indicate that low to moderate beer intake may increase HDL cholesterol levels without significantly altering liver function or contributing to artery stiffening. Nevertheless, it is important to note that these studies suggest that the benefits of light to moderate drinking may not outweigh the risks, as there was no associated decrease in LDL cholesterol or triglyceride levels.

In conclusion, while beer and other alcoholic beverages may have a small impact on cholesterol levels, especially HDL cholesterol, excessive consumption can interfere with cholesterol tests by raising triglyceride and total cholesterol levels. Therefore, it is crucial to drink in moderation, which is defined as one drink or less per day for women and two drinks or less per day for men.

HDL and LDL cholesterol

Cholesterol is a waxy, fat-like substance found in all the cells in your body. It is produced by the liver and is also present in certain foods, such as meat and dairy products. While your body needs some cholesterol to function properly, high cholesterol levels in your blood can increase your risk of coronary artery disease.

There are two main types of lipoproteins that carry cholesterol through your bloodstream: HDL (high-density lipoprotein) and LDL (low-density lipoprotein).

LDL cholesterol is often referred to as the "bad" cholesterol. High levels of LDL can lead to a buildup of cholesterol in your arteries, a condition known as atherosclerosis. This buildup, called plaque, can narrow your arteries and increase your risk of heart disease and stroke.

On the other hand, HDL cholesterol is considered the "good" cholesterol. It helps to remove excess LDL cholesterol from your body. HDL absorbs cholesterol in the blood and carries it back to the liver, where it is broken down and flushed out of your system. High levels of HDL can lower your risk of heart disease and stroke.

While moderate alcohol consumption has been linked to a reduced risk of heart disease, the specific effects of beer on HDL and LDL cholesterol are more complex. Beer can increase your triglyceride levels due to its carbohydrate and alcohol content, which can indirectly raise your total cholesterol levels. However, some studies suggest that beer may also increase HDL levels without significantly impacting LDL levels. Additionally, beer contains cholesterol-binding sterols, which may help reduce cholesterol, but the levels in beer are too low to have a significant impact.

In conclusion, while beer may have a modest impact on HDL levels, it does not appear to directly affect LDL cholesterol. However, excessive alcohol consumption can lead to health issues, including an increased risk of heart disease, stroke, obesity, and high triglyceride levels. Therefore, it is important to drink in moderation and prioritize healthy lifestyle choices, such as regular exercise and a balanced diet, to maintain optimal cholesterol levels.

Triglycerides and heart health

Triglycerides are a type of fat that circulates in your blood. They are the most common type of fat in your body. While some triglycerides are important for good health, high triglyceride levels in your blood can increase your risk of heart disease and stroke.

Beer contains carbohydrates and alcohol, two substances that raise triglyceride levels. Therefore, drinking beer can increase your triglyceride levels, and, as a result, your total cholesterol.

However, beer also contains plant compounds known as polyphenols, which are thought to exert antioxidant and anti-inflammatory effects. Some studies have found that people who drink alcohol in moderation have lower rates of heart disease and might even live longer than those who abstain.

The American Heart Association does not recommend that you start drinking beer or any other alcoholic beverages specifically to lower your cholesterol or improve your heart health. Instead, they advise watching your weight, eating a healthy diet, and exercising regularly to keep your cholesterol levels in check.

Alcohol and liver function

Alcohol-related liver disease (ARLD) refers to liver damage caused by excess alcohol intake. The liver is one of the most complex organs in the body, performing functions such as filtering toxins from the blood, aiding digestion, regulating blood sugar and cholesterol levels, and helping fight infection and disease.

Each time the liver filters alcohol, some liver cells die. While the liver can develop new cells, prolonged alcohol misuse over many years can reduce its ability to regenerate, leading to serious and permanent liver damage. ARLD has several stages of severity, including alcoholic fatty liver disease, alcoholic hepatitis, and cirrhosis.

Drinking a large amount of alcohol, even for just a few days, can lead to a build-up of fats in the liver, resulting in alcoholic fatty liver disease. This stage rarely causes symptoms but is a warning sign of harmful alcohol consumption. Fatty liver disease is reversible, and abstaining from alcohol for a few weeks to months can restore the liver to normal.

Alcoholic hepatitis is a potentially serious condition caused by alcohol misuse over a longer period. It can also occur due to binge drinking, which refers to consuming a large amount of alcohol in a short period. While mild alcoholic hepatitis is reversible with permanent abstinence, severe alcoholic hepatitis is life-threatening.

Cirrhosis is a stage of ARLD characterised by significant scarring of the liver. It is generally irreversible, but stopping alcohol consumption can prevent further damage and increase life expectancy. A liver transplant may be required in severe cases where the liver has stopped functioning and does not improve with abstinence.

The most effective way to prevent ARLD is to abstain from alcohol or stick to recommended drinking limits. Reducing or quitting alcohol consumption can have short-term and long-term benefits for liver health.

Drinking guidelines

The bottom line is that the risks of drinking alcohol far outweigh any potential benefits. The World Health Organization states that "no level of alcohol is safe for our health" and that the potential harms "start from the first drop of alcohol you consume".

If you are taking medication for high cholesterol, it is important to be aware that alcohol can affect how your body metabolises it. Alcohol is broken down in the liver and reconstructed as cholesterol and triglycerides. The more you drink, the more your levels of cholesterol and triglycerides rise. High levels of these waxy fats are not desirable for managing cholesterol or optimal health.

According to the National Institutes of Health (NIH), "drinking less is better for health than drinking more". The federal Dietary Guidelines for Americans, 2020-2025, advise that adults should limit alcohol intake to two drinks or fewer in a day for men and one drink or fewer in a day for women. This is not a daily average or target but a boundary on any given day when you might choose to drink.

A standard alcoholic drink is typically defined as:

• 12 ounces of regular beer (5% alcohol)
• 5 ounces of wine (about 12% alcohol)
• 1.5 ounces of a distilled spirit (about 40% alcohol, or 80 proof)

It's important to note that alcohol doesn't affect everyone in the same way. Females are much more sensitive to the effects of alcohol because they have lower levels of the enzyme alcohol dehydrogenase, which breaks down alcohol. Therefore, women absorb more alcohol into their bloodstream and are generally smaller than men.

If you are taking medication for high cholesterol, it is important to consult your doctor or healthcare provider about whether it is safe for you to consume alcohol and how much is safe to drink. They can provide appropriate testing and additional resources if needed.
