At 21 drinks per week, over a quarter of all deaths in that age group were attributable to alcohol. Assessing the risks and benefits of alcohol consumption remains an active area of research that may lead to major changes in official guidelines or warning labels. Data from the Centers for Disease Control and Prevention say more than 170,000 deaths per year — including 20% of deaths of young people aged 20 to 49 — are due to excessive alcohol use.
Alcohol and Memory Loss
In 2020, the American Cancer Society updated its guidelines to say that cutting alcohol out of a person’s diet completely is best for cancer reduction and prevention. One serving of alcohol is defined as 5 ounces for wine and just 1 1/2 ounces for hard alcohol, far less than what is typically served in bars, restaurants and people’s homes. Heavy drinking is typically defined as consuming eight drinks or more per week, according to the CDC. “When you talk about risk versus benefit, it’s one thing to say there is no benefit,” said Dr. Jennifer Ashton, a board-certified OB-GYN and ABC News chief medical correspondent, who was not involved in the research.

However, the analysis found light drinking, up to three drinks per week, did not increase the risk of premenopausal breast cancer as much as it heightened the relative risk of other conditions, such as liver cirrhosis. Researchers have long suspected women may experience worse alcohol-related harm than men because of their different body composition and how they metabolize alcohol. In other words, it takes less alcohol for the average woman to reach the same blood-alcohol level as the average man. For this reason, binge drinking or heavy episodic drinking — usually defined as four or more drinks in one occasion for women (five or more for men) — is thought to carry greater risks. Some research included in the report linked binge drinking to a higher risk of breast cancer.
Others soon cast doubt on the possibility that red wine could really have any causal relationship with longevity. The “alcohol is good for you” narrative eroded and, in the past year, seems to have fully collapsed. Underage drinking increases the risk of anxiety, depression, and low self-esteem, which can affect the brain long term. Heavy drinking may weaken parts of the brain that are responsible for cognitive function and emotion regulation. Heavy drinking slows the cerebral cortex, which takes in and processes new information in your brain. Alcohol also dulls sensory uptake, so it might be difficult to take in new information.

Scar tissue impairs the liver’s ability to create proteins, filter the blood, and other bodily functions. The risk of death was also found to be greater for women, with a 61% increased risk for women who drink more than 2 ounces of alcohol per day. None of the technical review meetings were open to the public, though two invitation-only “stakeholder” meetings admitted public health advocates even a little alcohol can harm your health, research shows the new york times and members of the alcohol industry. The study did not differentiate between different types of alcohol, since most experts believe it is the amount of pure ethanol that matters more than the choice of beverage.
It seems very likely that all associations—positive and negative—are overstated relative to the truth. Generally, when researchers are able to adjust for some demographic differences, the relationship between alcohol and health gets smaller. This, in turns, suggests that if they could adjust for more differences, it would get smaller still. Whether these relationships would be smaller but still positive, or really zero, is something we cannot know from the data we have. In a study, those who ate more organic produce, dairy, meat and other products had 25 percent fewer cancer diagnoses over all, especially lymphoma and breast cancer. Associations between drinking and cancer were particularly strong for cancers of the mouth, throat, stomach and colon.
- For this reason, binge drinking or heavy episodic drinking — usually defined as four or more drinks in one occasion for women (five or more for men) — is thought to carry greater risks.
- Some scientists wondered if people who drank modestly might have healthier diets or other beneficial habits.
- Data shows that even casual drinkers face a greater risk of cancer, most commonly liver and throat cancers but also colon and head and neck cancers, in addition to breast cancer.
- The ICCPUD panelists assumed “that 10% of alcohol consumed by cohort participants was not captured” in such studies.
- In a 1991 segment on 60 Minutes, a French researcher claimed that red-wine consumption was responsible for good health in France.
Shifting understanding of risks
Scientists even put forward a mechanistic theory for why red wine was healthy, involving a compound called resveratrol. Drinking at low or moderate levels can be part of a healthy lifestyle. This is no more than seven drinks per week for females and no more than 14 per week for males. Some people can safely stay within this recommendation for low-risk drinking. A study published in 2021 found that heavy drinking may lead to loss of brain volume. The researchers noted that people with alcohol use disorder (AUD) had less brain matter than others.
- A number of experts have recommended revision of the guidelines toward lower amounts, as more studies have linked even moderate alcohol consumption to health risks.
- The researchers linked alcohol consumption to various types of cardiovascular problems, including stroke.
- During the coronavirus pandemic, some officials advocated strongly for long-lasting school closures, arguing that keeping kids at home was the only way to prevent in-school spread among students and teachers.
- Heavy drinking for females is eight or more drinks per week, and 15 or more drinks per week for males.
- Research shows that heavy drinking can speed up memory loss and cognitive decline compared with those who did not drink, had quit drinking, or were light-to-moderate drinkers.
- At three drinks per day, those risks increased to 22.6 per 1,000 for men and 66.9 per 1,000 for women.
The analysis, published recently in JAMA Network Open, looked at over 100 studies with nearly 5 million participants in all. Alcohol has long been considered a “social lubricant” because drinking may encourage social interaction. Having a drink while getting together with family or friends is often part of many special occasions.
“It’s another thing, at certain levels, to find a risk, and that’s what this new research found.” Drinking recommendations in the U.S. have gone relatively unchanged for decades. Since the 1990s, the guidelines have told the public to drink alcohol “in moderation,” if at all. Heavy drinking can also cause problems well beyond the health of the drinker — it can damage important relationships. It’s all too common that problem drinking disrupts bonds with a spouse, family members, friends, coworkers, or employers. As companies roll out the pink beer in October to raise awareness of the disease, one group is urging young women to think twice.

Of course, no one needs to wait for new guidelines or warning labels to curb their drinking. Many are exploring ways to cut back, including the Dry January Challenge or alcohol-free drinks. By contrast, another 2023 study found similar rates of death between nondrinkers and light to moderate drinkers. Adolescents are more susceptible to brain damage from alcohol use than adults.
Drinking a glass of wine a day will not help you live longer, according to a new analysis of alcohol research that debunks a longstanding belief about the possible health benefits of drinking alcohol moderately. In early December, scientists issued their report on the role of food in health promotion and disease prevention. Dietary guidelines are just recommendations, but they influence food assistance programs, policy, school meals, and clinical practice. They also reflect social and scientific changes over time about what Americans ought to eat and drink.
Current alcoholic beverage labels in the US warn of the risks of driving under the influence of alcohol, adverse effects on general health, and risks for a developing fetus — but there’s no mention of cancer. For millions of people, it’s a regular part of the dining experience, social and sports events, celebrations, and milestones. And the alcoholic beverage industry is a major economic force, responsible for more than $250 billion in sales annually in the US. People who drink regularly may notice that alcohol does not have the same effect on them as it used to. You build up a tolerance over time and do not feel as good as you once did with the same amount of alcohol. High alcohol consumption can damage your brain and the rest of your body.
