Beer And High Cholesterol: What's The Verdict?

Beer is a popular alcoholic drink, but can you drink it if you have high cholesterol? The answer is complicated. Beer itself doesn't contain any natural cholesterol, but it can still affect your cholesterol levels. Beer contains carbohydrates and alcohol, which can quickly raise your triglyceride levels, a type of fat that is part of your total cholesterol count. On the other hand, beer also contains cholesterol-binding sterols, which can help remove cholesterol from your body. So, while beer may not directly lower your cholesterol, it has a mixed impact on your cholesterol levels.

Beer can increase HDL (good) cholesterol levels

Beer is one of the most popular alcoholic drinks in the world. While beer is not cholesterol-free, the cholesterol it contains is not the type that negatively impacts health. In fact, beer contains phytosterols, or plant sterols, which are compounds that bind to cholesterol and help remove it from the body. However, the amount of sterols in beer is too low to significantly impact cholesterol reduction.

That said, beer has been found to increase levels of HDL (high-density lipoprotein) cholesterol, also known as "good" cholesterol. HDL helps to trap and carry LDL (low-density lipoprotein) cholesterol, or "bad" cholesterol, to the liver for breakdown and elimination. By increasing HDL levels, there may be less LDL cholesterol available to stick to artery walls and cause coronary artery disease (CAD).

This positive effect of beer on HDL cholesterol has been documented in several studies. A 2018 study published in Nutrients found that moderate beer consumption by overweight adults (30 grams of alcohol per day for males and 15 grams per day for females) increased HDL levels after four weeks, without negatively impacting liver function or artery health. Similarly, a 2020 review of 26 high-quality studies in PLoS One confirmed that low to moderate beer consumption increases HDL levels but has no effect on LDL or triglyceride levels.

While beer may have a positive impact on HDL cholesterol, it's important to note that excessive alcohol consumption can lead to serious health issues, including heart disease, stroke, liver disease, and cancer. Therefore, drinking in moderation is key. For those who choose to drink, it's recommended to limit consumption to no more than two beers per day for males and one beer per day for females.

Beer can increase total cholesterol and LDL (bad) cholesterol levels

Beer does not contain any natural cholesterol. However, beer contains carbohydrates and alcohol, two substances that can increase triglyceride levels. Triglycerides are a type of fat that is included in the total cholesterol count. Therefore, an increase in triglycerides leads to an increase in total cholesterol.

Research has shown that heavy drinking is associated with elevated levels of LDL cholesterol and total cholesterol. In addition, a study in 1,519 people found that binge drinking was associated with a 2 to 8-fold increased risk of high triglyceride and total cholesterol levels.

The American Addiction Center (AAC) also lists alcohol as a drug that can interact with the body to produce high levels of LDL or triglycerides. Furthermore, the AAC states that beer has a particularly negative effect on triglyceride levels.

According to the Centers for Disease Control and Prevention (CDC), the risks associated with alcohol consumption, including increased cholesterol levels, increase with the amount of alcohol consumed. Therefore, it is recommended that people either avoid alcohol altogether or drink in moderation.

Beer can increase triglyceride levels

Beer can increase your triglyceride levels. Triglycerides are a type of fat in the blood, which is stored in cells and used for energy between meals. Beer contains carbohydrates and alcohol, two substances that raise triglycerides quickly. People who are more sensitive to the effects of beer can experience even higher levels of triglycerides.

Since triglycerides are part of the total cholesterol count, this means that if your triglycerides increase, your total cholesterol increases as well. Ideally, your triglyceride level should be below 150 milligrams per decilitre (mg/dL).

While light to moderate alcohol intake may improve HDL (good) cholesterol, heavy drinking can increase total cholesterol, LDL (bad) cholesterol, and triglycerides. This raises the chance of developing cardiovascular disease.

According to the American Addiction Center (AAC), drinking more than moderate amounts of wine, beer, or liquor can have a detrimental effect on a person's health, including causing elevated cholesterol levels. Beer has a particularly negative effect on triglyceride levels. The AAC lists alcohol as a drug that can interact with the body to produce high levels of LDL or triglycerides.

Elevated triglycerides may cause a thickening in the blood vessels, thereby increasing the risk of heart disease or stroke.

Beer contains cholesterol-binding sterols

However, the sterols in beer—sitosterol and ergosterol—are present in very low levels. Even whole-grain beers contain too little of these sterols to significantly impact cholesterol reduction. Some research on mice has suggested that moderate beer consumption can reduce cholesterol in the liver and cholesterol deposits in the aorta, but the components responsible for this are not yet fully understood.

While beer does contain cholesterol-binding sterols, it also contains carbohydrates and alcohol, which can quickly raise triglyceride levels. Triglycerides are a type of fat that contributes to total cholesterol levels. Therefore, despite the presence of sterols, drinking beer may not effectively lower your cholesterol.

It is important to note that the amount and frequency of alcohol consumption play a significant role in its impact on cholesterol levels. Light to moderate drinking may increase HDL ("good") cholesterol, while heavy drinking is associated with elevated levels of LDL ("bad") cholesterol, total cholesterol, and triglycerides.

Beer is not considered a healthy drink

Beer is often viewed as a drink with little nutritional value, and while it does contain various vitamins and minerals, it is not a good source of these nutrients compared to whole foods like fruits and vegetables. Additionally, the calories and alcohol content in beer can contribute to weight gain and other health issues.

Furthermore, the impact of beer on cholesterol is mixed. While some studies suggest that moderate beer consumption may increase levels of "good" cholesterol (HDL), it is important to note that beer also raises triglyceride levels, which are part of the total cholesterol count. Beer also contains cholesterol-binding sterols, but the levels are too low to have a significant impact on reducing cholesterol.

In conclusion, while light to moderate beer consumption may have some health benefits, it is important to consume it in moderation and not as a replacement for a nutritious, balanced diet and a healthy lifestyle that includes regular exercise.
