Red wine has been part of social, religious, and cultural events for centuries, and its potential health benefits have been debated for some time. While some believe that a glass of red wine a day is a valuable part of a healthy diet, others think wine is overrated. Research has shown that moderate red wine consumption can increase the expression of longevity-related genes, improve metabolic health, and lower the risk of several diseases, including heart disease and type 2 diabetes. However, heavy drinking is harmful to health and can contribute to weight gain, stroke, high blood pressure, and other cardiovascular issues. So, is it okay to drink red wine on a diet? The answer may depend on individual circumstances, and it's important to remember that while red wine may have some health benefits when consumed in moderation, it is still a form of alcohol, which has been linked to adverse health effects, including an increased risk of certain cancers.

What You'll Learn
Red wine's health benefits
Red wine has been part of social, religious, and cultural events for centuries. In the past, people theorized that red wine benefits health, particularly when consumed alongside a balanced diet. In recent years, science has indicated that there could be some truth to these claims.
Heart Health
Red wine has been linked to improved heart health. A 2013 review reported that drinking red wine is associated with a lower risk of coronary heart disease, which is a leading cause of disease and death in the United States. The authors concluded that red wine might have cardioprotective effects. Additionally, some studies show that red wine helps reduce the risk of plaque buildup in the arteries. However, the American Heart Association (AHA) states that it is unclear if there is a cause-and-effect relationship, and other factors may play a role. For example, people who drink red wine in moderation may also follow a more healthful lifestyle or eat a Mediterranean diet.
Brain Health
The polyphenols in red wine prevent the formation of certain proteins that create toxic plaques that can kill brain cells. These polyphenols can also lessen the plaque toxicity that is already present in the body, thus reducing cognitive decline. Research shows that drinking in moderation could reduce the risk of Alzheimer's disease or other forms of dementia compared to no alcohol intake.
Gut Health
A 2018 study reported that red wine and grape polyphenols might improve gut microbiota, contributing to a healthy gut. However, the research is limited, and doctors need more evidence before understanding the true effects of red wine on gut health.
Cancer
While there are studies indicating that drinking red wine in moderation could reduce the risk of certain cancers, the National Cancer Institute (NCI) states that there is strong evidence that drinking alcohol, especially in heavy amounts over time, can also cause certain cancers. This is partly because it creates toxins and damages body tissues in the body. The potential adverse effects of alcohol may outweigh any benefit from resveratrol. The NCI links alcohol use with various cancers, including mouth, throat, liver, breast, and colon cancer.
Diabetes
A large study of current drinkers showed that a moderate intake of alcohol, especially wine, with meals could reduce the risk of type 2 diabetes. The results were not the same for heavy drinking or drinking alcohol without a meal. Additionally, a 2015 study found that moderate red wine intake is usually safe and may "modestly decrease cardiometabolic risk" in people with type 2 diabetes.
It is important to note that while red wine may offer potential health benefits, it is still an alcoholic beverage. Excessive alcohol consumption can have detrimental effects on health, and health experts do not recommend that non-drinkers start drinking alcohol. If you enjoy alcohol in moderation, red wine may be worth considering due to its potential health benefits.

Red wine and weight gain
Red wine is often believed to be a part of a healthy diet, with some evidence suggesting that drinking it in moderation may offer health benefits. However, it is essential to understand the relationship between red wine consumption and weight gain or loss. While red wine may not directly cause weight gain, excessive drinking can contribute to an overall increase in body weight over time.
Red wine is an alcoholic beverage made from fermenting dark-coloured grapes, including the grape skin. This process results in a deep red colour and a bitter yet pleasant taste due to the presence of tannins. The alcohol content in red wine typically ranges from 12% to 15%, and a standard glass of red wine contains anywhere between 92 and 175 calories.
When it comes to weight gain or loss, several factors come into play. Firstly, alcohol behaves similarly to carbohydrates in our bodies, and excessive drinking can lead to weight gain. Additionally, heavy drinking can contribute to poor food choices, as it increases the impulse to consume more calories. Therefore, it is crucial to practise moderation and be mindful of your overall calorie intake when including red wine in your diet.
Secondly, drinking red wine, or any alcoholic beverage, can disrupt healthy eating habits and interfere with weight loss goals. Alcohol can lower inhibitions, leading to decreased willpower and increased difficulty in adhering to a healthy diet. This effect may vary depending on individual differences, such as physiology and willpower. However, for those actively trying to lose weight, reducing alcohol consumption, including red wine, may be necessary to achieve their goals.
Lastly, while red wine may not directly cause weight gain, excessive drinking can lead to an overall unhealthy lifestyle. Heavy drinking is associated with several negative health consequences, including an increased risk of cancer, stroke, high blood pressure, and other cardiovascular issues. Therefore, it is essential to practise moderation and ensure that red wine consumption aligns with a balanced and healthy diet, such as the Mediterranean diet, which has been associated with various health benefits.
In conclusion, while red wine may not directly cause weight gain, excessive consumption can contribute to an unhealthy lifestyle and increased body weight over time. Practising moderation, being mindful of calorie intake, and combining red wine consumption with a healthy diet and exercise can help maintain a stable body weight. Additionally, consulting with a healthcare professional or a doctor can provide personalised guidance on including red wine in your diet while considering your specific circumstances.

Red wine and weight loss
Red wine is often believed to be a part of a healthy diet, especially the Mediterranean diet. The Mediterranean diet includes whole grains, lean meat, fish, fruits, olive oil, and red wine. However, with mounting evidence that alcohol could be detrimental to health, the inclusion of red wine in the diet has become controversial.
Research has shown that moderate red wine consumption can have health benefits, including boosting heart, gut, and brain health. It may also reduce the risk of certain cancers. The antioxidants in red wine, known as polyphenols, can lower blood pressure and reduce the risk of plaque buildup in the arteries. Resveratrol, another antioxidant found in red wine, may offer additional benefits such as reducing inflammation and protecting the brain and heart. Small amounts of red wine, when consumed with a balanced diet, are generally considered acceptable.
However, it is important to note that excessive alcohol consumption, including red wine, can have negative health consequences. Heavy drinking can contribute to stroke, high blood pressure, and other cardiovascular issues. Additionally, alcohol has been linked to various cancers, including mouth, throat, liver, breast, and colon cancer. The potential adverse effects of alcohol may outweigh any benefits from the antioxidants in red wine.
To maintain a healthy weight while including red wine in your diet, it is recommended to practice moderate drinking behavior. This may include limiting drinking to early evening to keep your metabolism up and reducing the impulse to eat late at night. Walking in the early evening can also help keep your metabolism up and reduce the urge to overeat. It is also important to drink water when consuming wine to maintain the balance of water in your cells, as alcohol is a diuretic. While wine may be included in a healthy diet, it is always advisable to consult a healthcare professional for personalized advice.

Red wine in the Mediterranean diet
Red wine is considered a part of the Mediterranean diet. However, this does not necessarily mean that it is healthy or that non-drinkers should start drinking it. The Mediterranean diet is modelled after the traditional foods eaten in countries that border the Mediterranean Sea, including France, Spain, Greece, and Italy, where red wine is a popular drink.
The Mediterranean diet is associated with several health benefits, including improved heart health and a reduced risk of certain chronic illnesses. However, there is controversy regarding the inclusion of red wine in the diet due to the well-established link between alcohol consumption and various adverse health outcomes, such as cancer and cardiovascular issues.
Some experts argue that red wine should be removed from the Mediterranean diet because alcohol is a known human carcinogen and has been linked to cancers, including breast, liver, oesophageal, colorectal, and head and neck cancers. They emphasise that there is no safe amount of alcohol consumption, and even moderate drinking can have negative effects, especially for younger individuals.
On the other hand, some research suggests that moderate red wine consumption within the context of the Mediterranean diet may offer potential health benefits. For example, a compound in red wine called resveratrol may provide protection for the brain, heart, and body by acting as an antioxidant and reducing inflammation. Additionally, the Mediterranean way of drinking, which involves consuming small amounts of red wine with meals and in social settings, may contribute to the overall health benefits associated with the diet.
While the inclusion of red wine in the Mediterranean diet remains controversial, it is important to note that individual circumstances play a role in determining whether and how much alcohol to consume. Experts generally recommend limiting alcohol intake and prioritising a healthy lifestyle that includes physical activity, a balanced diet, and other facets of the Mediterranean lifestyle.

Risks of drinking red wine
While some studies suggest that drinking red wine in moderation may have certain health benefits, there are also risks associated with its consumption.
Firstly, it is important to note that excessive alcohol consumption, including red wine, can lead to serious health issues. According to the Centers for Disease Control and Prevention, excessive alcohol use resulted in approximately 178,000 deaths in the United States between 2020 and 2021, reducing the lives of those affected by an average of 24 years. Short-term health risks of excessive alcohol consumption include alcohol use disorder, increased risk of certain cancers, and damage to vital organs such as the liver.
Secondly, while some studies suggest that moderate red wine intake may reduce the risk of heart disease, other studies dispute this claim. For example, a 2006 analysis that controlled for health-affecting variables did not find any cardiovascular benefits of drinking red wine. Additionally, newer research suggests that even one glass of wine per day increases the risk of high blood pressure and heart problems.
Thirdly, while red wine contains antioxidants and substances that may provide health benefits, the ethanol or alcohol present in wine is a Group 1 carcinogen. This means that it has the potential to cause cancer, especially with heavy and prolonged consumption. The National Cancer Institute (NCI) states that there is strong evidence linking alcohol consumption to an increased risk of various cancers, including mouth, throat, liver, breast, and colon cancer.
Lastly, while some studies suggest that moderate red wine consumption may improve metabolic health and reduce the risk of chronic diseases, these findings may be influenced by confounding factors such as diet and lifestyle. For example, red wine drinkers may be more likely to have a healthier diet, engage in physical activity, and have better access to healthcare, which could contribute to improved health outcomes.
In conclusion, while there may be potential health benefits associated with moderate red wine consumption, it is important to consider the risks involved. Excessive consumption can lead to serious health issues, and even moderate intake may have negative consequences. As such, healthcare professionals generally do not recommend initiating alcohol consumption for health reasons, and it is essential to weigh the risks and benefits before making informed decisions regarding alcohol intake.
