Beer Drinking And Cholesterol: What's The Connection?

Alcohol is a staple of the American diet, with beer being the preferred alcoholic beverage of 43% of Americans who drink. But what does this mean for cholesterol levels?

Cholesterol is a waxy, fat-like substance that travels through your blood. While your body needs cholesterol to function, high levels can increase the risk of heart disease.

The relationship between alcohol and health is complex and depends on many factors, including how much and how often you drink. Light to moderate alcohol intake has been shown to raise HDL, the good type of cholesterol, which lowers the amount of plaque and inflammation in the arteries. However, heavy drinking is consistently linked to higher LDL cholesterol and triglyceride levels. Beer, in particular, contains carbohydrates and alcohol, two substances that raise triglycerides quickly.

So, while light to moderate drinking may not harm cholesterol levels, heavy drinking can. If you're concerned about your cholesterol levels or alcohol intake, it's best to consult a healthcare professional.

Beer raises triglyceride levels, which are part of the total cholesterol count

Beer and Cholesterol

Beer does not contain any natural cholesterol, but it can still affect your cholesterol levels. When you drink alcohol, it is broken down and rebuilt into triglycerides and cholesterol in the liver. Beer contains carbohydrates and alcohol, two substances that increase triglyceride levels quickly.

Triglycerides are a type of fat in the blood, which is stored in cells and used for energy between meals. When we refer to total cholesterol, it is a combination of HDL and LDL cholesterol plus triglycerides.

Beer contains substances such as barley malt, yeast, and hops, which all contain phytosterols. Phytosterols are plant compounds that bind to cholesterol and help remove it from your body. However, the levels of sterols in beer are too low to have a significant impact on reducing cholesterol.

Since triglycerides are part of the total cholesterol count, an increase in triglyceride levels will lead to an increase in total cholesterol. Ideally, your triglyceride level should be below 150 milligrams per deciliter (mg/dL). If your triglyceride levels become too high, they can build up in the liver, causing fatty liver disease. This can lead to an increase in cholesterol levels as the liver becomes less effective at removing cholesterol from the blood.

To lower your cholesterol levels, it is recommended to cut down on alcohol consumption, maintain a healthy diet, exercise regularly, and watch your weight.

Beer contains cholesterol-binding sterols, but at low levels

Beer does not contain any natural cholesterol. However, it does contain carbohydrates and alcohol, which are substances that can raise triglyceride levels. Triglycerides are a type of fat that is included when referring to total cholesterol. Beer also contains cholesterol-binding sterols, which are plant compounds that bind to cholesterol and help remove it from your body. These sterols are called phytosterols or plant sterols, and they are added to some foods and drinks marketed as cholesterol-reducing.

However, the sterols found in beer are at very low levels. Even a whole-grain beer contains too little of these sterols to significantly reduce cholesterol. So, while beer does contain cholesterol-binding sterols, the amount is too low to have a meaningful impact on lowering cholesterol.

Research on mice has suggested that moderate beer consumption can reduce cholesterol in the liver and cholesterol deposits in the aorta, the largest artery in the body. These studies indicate that some components in beer may reduce the risk of heart disease by changing how lipoproteins are metabolised. However, the specific components responsible for these potential benefits are not yet fully understood.

While beer may have some potential benefits for heart health, it is important to note that excessive alcohol consumption can lead to an increased risk of heart disease, stroke, high blood pressure, obesity, and elevated levels of triglycerides in the blood. Therefore, drinking in moderation is generally recommended.

Drinking alcohol can lead to weight gain, which raises the risk of heart disease

Beer does not contain any natural cholesterol, but it can still raise your cholesterol levels. When you drink alcohol, it is broken down and rebuilt into triglycerides and cholesterol in the liver. Beer contains carbohydrates and alcohol, two substances that raise triglycerides quickly. Since triglycerides are part of the total cholesterol count, this means that if your triglycerides increase, so does your total cholesterol.

Drinking alcohol can also lead to weight gain, which in turn raises the risk of heart disease. Alcohol is high in kilojoules (or calories) and can cause weight gain in four ways: it stops your body from burning fat, it's high in kilojoules, it can make you feel hungrier, and it can lead to cravings for salty and greasy foods. The link between alcohol consumption and weight gain is stronger in men than in women, partly because men tend to consume more alcohol and are more likely to drink beer, which is carbohydrate-rich and provides more energy than wine per serving.

Heavy drinking and binge drinking have been more consistently linked with weight gain and adiposity. Alcohol may stimulate food intake and influence hormones linked to satiety, such as leptin and glucagon-like peptide-1 (GLP-1). It can also affect central neurological pathways in the brain, such as opioid, serotonergic, and GABAergic pathways, which may increase appetite.

In addition to weight gain, drinking alcohol can lead to an inactive lifestyle, obesity, and alcoholism, all of which increase the risk of heart disease. Therefore, it is important to monitor your alcohol consumption as part of a balanced diet and a healthy lifestyle.

Alcohol can cause high blood pressure, which also raises the risk of heart disease

Beer does not contain any natural cholesterol. However, drinking beer can increase your triglyceride levels, which are part of your total cholesterol count. Beer contains carbohydrates and alcohol, which are substances that raise triglycerides quickly. Therefore, drinking beer can increase your total cholesterol levels.

Alcohol can also cause high blood pressure, which raises the risk of heart disease. Firstly, alcohol increases hormones that cause arteries to tighten and constrict, which can change the force used to pump blood around the body. Secondly, alcohol affects the nervous system, which helps regulate blood pressure. Thirdly, alcohol impacts receptors in blood vessels near the heart that help maintain blood pressure. Lastly, alcohol increases stress hormones like cortisol, which can increase heart rate and blood pressure.

High blood pressure puts strain on the heart and can increase the build-up of fatty material (plaque) in blood vessels. This can lead to blocked arteries that supply blood to the heart, brain, and other vital organs, causing heart disease, heart attack, and stroke.

Drinking beer in moderation may have some benefits for your heart health

Several studies have found that light to moderate beer intake may be associated with a lower risk of heart disease. For example, a 12-week study in 36 overweight adults showed that moderate beer intake – one drink per day for women and two drinks per day for men – improved the antioxidant properties of HDL ("good") cholesterol and enhanced the body's ability to remove cholesterol. Another large review supported these findings, suggesting that low to moderate beer intake could reduce the risk of heart disease to a similar extent as wine.

Beer also contains cholesterol-binding sterols, which are plant compounds that help remove cholesterol from the body. While the levels of these sterols in beer are too low to have a significant impact on cholesterol reduction, they may still contribute to overall heart health.

Additionally, moderate beer intake has been linked to improved blood sugar control, stronger bones, and a reduced risk of dementia. However, heavy and binge drinking can counteract these potential benefits and increase the risk of various health issues, including depression, weight gain, liver disease, and certain types of cancer.

It's worth noting that the positive effects of moderate beer consumption can also be achieved through a well-balanced diet rich in whole foods like fruits and vegetables. As always, it's important to consult with a healthcare professional to determine what is safe and appropriate for your individual needs and circumstances.
