Red Wine and Liver Health
Red wine has been a subject of interest when it comes to its impact on liver health. In this section, we will explore the effects of red wine on liver enzymes and the findings of studies on moderate red wine consumption.
Moderate Red Wine Consumption Study
A study conducted on healthy centenarians found that long-term moderate red wine consumption, defined as ≤500 ml per day, had no negative effect on circulating liver enzyme activities. Laboratory tests showed low levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), indicating a lack of liver damage.
Effects of Red Wine on Liver Enzymes
Moderate red wine consumption, especially as part of a healthy diet like the Mediterranean diet, has been associated with reducing the risk of heart disease, stroke, and early death. It has been suggested that drinking small amounts of red wine helps retain "good" HDL cholesterol and reduces oxidative damage in the body.
Additionally, moderate alcohol consumption, including red wine, has been linked to lower liver fibrosis in individuals with nonalcoholic fatty liver disease (NAFLD). This benefit is observed when alcohol intake is defined as up to 70 grams (g) or less than 2.5 ounces (oz) per week [3]. A meta-analysis of 43,175 individuals indicated a beneficial impact of moderate alcohol consumption in protecting against non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) development.
Moreover, moderate alcohol consumption has been shown to reduce insulin resistance, a key factor in liver steatosis and fibrosis. Improved liver fibrosis has been observed in individuals with moderate alcohol intake, although further research is needed to fully understand the underlying mechanisms.
It's important to note that moderation is key when it comes to consuming red wine or any alcoholic beverage. Excessive alcohol consumption can lead to liver cirrhosis and other negative health consequences. If you have concerns about your liver health or alcohol consumption, it's recommended to consult with a healthcare professional.

While moderate red wine intake may offer health benefits, it's important to be aware of the potential risks associated with excessive alcohol consumption, including red wine. Excessive alcohol consumption can have negative consequences on liver health and overall well-being.
Liver Cirrhosis and Alcohol Dependence
Excessive alcohol consumption can lead to liver cirrhosis, a condition characterized by the scarring of liver tissue. This scarring is a result of chronic alcohol abuse and can impair liver function. The scarring process is irreversible, and if left untreated, it can progress to liver failure.
A concerning trend is the increasing number of younger women being hospitalized for alcoholic hepatitis, with a significant proportion of them already having cirrhosis, indicating liver damage by scarring. It is worth noting that fatty liver occurs in 90% of people who consume more than 45-60 ounces of alcohol per day, contributing to the development of cirrhosis.
Alcohol abuse can also disrupt the balance of bacteria in the gut, leading to bacterial overgrowth and the potential for migration through the intestinal walls. If these bacteria reach the liver, it can result in liver damage.
Negative Health Consequences
Excessive alcohol consumption, including red wine, can have various negative health consequences beyond liver cirrhosis. These include alcohol dependence, cancer, heart disease, and weakened immune systems. It's important to note that these risks outweigh any potential benefits of red wine consumption.
Alcohol abuse can also cause damage to the heart muscle, a condition known as cardiomyopathy, and induce irregularities in the heartbeat, known as arrhythmias. Additionally, it can increase blood pressure and the risk of heart attacks.
It's crucial to understand that while moderate red wine consumption may have some health benefits, excessive alcohol consumption can lead to severe health issues. It is recommended to consume alcohol in moderation and to be aware of the potential risks associated with excessive alcohol intake.
