For many people, alcohol is not only a spice in life, but also a lubricant for social activities. Whether it's a family gathering, a dinner with friends, or even a drink alone, alcohol plays an important role.
However, as we get older, especially those over the age of 35, the negative effects of excessive alcohol consumption on the body begin to appear, and one of the most common problems is high blood lipids.
The relationship between alcohol consumption and blood lipid levels
How does alcohol affect our blood lipid levels? Drinking alcohol stimulates the release of fatty acids from adipose tissue, while promoting the synthesis of triglycerides in the liver.
Elevated triglyceride levels directly lead to an increase in blood lipids. Alcohol also disrupts the liver's regulation of lipid metabolism, increasing levels of low-density lipoprotein (LDL, the "bad" cholesterol) and decreasing the levels of high-density lipoprotein (HDL, the "good" cholesterol). These changes all increase the risk of cardiovascular disease.
According to a 2024 study by Toniolo et al., drinking ≥ 30 grams per day significantly increases body weight and body fat. The study, conducted in Italy with thousands of participants, showed that frequent alcohol consumption and overeating significantly increased the risk of hyperlipidemia.
Similarly, the 2022 study by Veenstra et al. also noted that non-alcoholic caloric intake was similar for alcohol consumers and non-consumers, but the former had a higher total caloric intake due to the additional alcohol caloric intake, leading to body fat and weight gain. The study was conducted in the Netherlands and involved a large number of adult volunteers.
The effects of alcohol consumption on overall health
Drinking alcohol isn't just about increasing blood lipids. It also affects our nutritional status and weight through a variety of mechanisms. Alcohol is a known appetite stimulant that increases appetite and energy intake by inhibiting leptin, glucagon-like peptide-1, and serotonin. Alcohol also enhances the effects of γ-aminobutyric acid, endogenous opioids, and neuropeptide Y, which work together to increase the appetite and energy intake of drinkers.
According to Toniolo et al., female drinkers consume significantly more total calories during drinking than non-drinkers, leading to weight and fat gain. This effect is particularly pronounced among female drinkers, who tend to substitute alcohol for other energy sources, resulting in an increase in total caloric intake.
Hyperlipidemia and the specific dangers of alcohol
The health risks associated with high blood lipids are obvious. High blood lipids can cause the blood to become viscous and increase the risk of atherosclerosis, which can lead to cardiovascular diseases such as heart disease and stroke. Elevated levels of triglycerides and LDL, especially LDL, can exacerbate these problems.
A 2024 study conducted by Toffolo et al. found that moderate to heavy alcohol consumption (≥30 grams of alcohol per day) significantly increased serum triglyceride and LDL levels. The study, conducted in the United States, showed that frequent alcohol consumption and overeating significantly increased the risk of hyperlipidemia.
Drinking alcohol not only affects blood lipid levels, but it can also cause serious damage to the liver. Long-term excessive alcohol consumption can lead to fatty liver disease, alcoholic hepatitis, and even cirrhosis. The liver is an important organ for lipid metabolism, and impaired liver function can further exacerbate the risk of hyperlipidemia.
Healthy drinking recommendations
So, how can we drink healthily? According to the recommendations of the Dietary Guidelines for Chinese Residents, adult men should drink less than 25 grams of alcohol per day, and women should not exceed 15 grams. If you exceed this amount, you will be drinking too much alcohol and will significantly increase your health risks.
Scientific drinking and a healthy lifestyle are key to reducing the risk of hyperlipidemia. Drink alcohol within a reasonable range and avoid overeating.
Reasonable diet and moderate exercise are also important means to prevent and control hyperlipidemia. Eating more foods rich in dietary fiber, such as whole grains, fruits and vegetables, and less high-fat, high-sugar foods can effectively control blood lipid levels.
Conclusions and prospects
The effects of alcohol consumption on blood lipids and overall health are significant and complex. While moderate alcohol consumption may have some benefits for cardiovascular health, excessive alcohol consumption significantly increases the risk of hyperlipidemia, high blood pressure, and cardiovascular disease.
The health recommendation is that men should not drink more than 25 grams of alcohol per day, and women should not drink more than 15 grams per day. If you already have hyperlipidemia or other cardiovascular diseases, you should try to avoid alcohol.
Future research should further explore the specific effects of different types of alcohol consumption on health, and consider the impact of individual differences (e.g., gender, genetics, and lifestyle) on the findings. More longitudinal studies should be conducted to better understand the cumulative health effects of long-term alcohol consumption.
Through these detailed research data and analysis, it can be seen that alcohol consumption has a significant negative impact on high blood lipids and overall health. To prevent and manage hyperlipidemia, individuals should be cautious about alcohol consumption and follow healthy drinking guidelines.
