Drinking too much alcohol is clearly bad for health, but is drinking a moderate amount beneficial? The jury is out.
Some people feel a drink at the end of a tough day helps them unwind and relax. Others may see a daily glass of red wine as a way to boost heart health. This kind of moderate drinking has been associated in some studies with positive health effects, but cause-and-effect evidence is lacking, and alcohol carries serious risks to health and safety. Understanding the science behind the risks and benefits of alcohol consumption can help us make informed decisions about our drinking.
Red wine is often singled out for potential health benefits. It contains bioactive compounds called polyphenols which have been associated with cardiovascular health. It is important to recognize that all of the potentially beneficial compounds in red wine are also found in other foods and beverages. For example, flavonoids, which account for over 85 percent of the polyphenols in red wine, are common in many vegetables, seeds, nuts, spices, and herbs. Resveratrol, a much-hyped compound being studied for health benefits, is found in grape skins and wine, but also in more than 70 other plant species, including berries, peanuts, and cocoa.
The detrimental effects of excess alcohol intake on heart health are well documented. Drinking a lot over a long time or binge drinking can damage the heart, causing problems including stretching of the heart muscle (cardiomyo-pathy), irregular heartbeat (atrial fibrillation), high blood pressure, and stroke. The potential benefits of red wine drinking, particularly in excess, may therefore be outweighed by potential risks, especially since the beneficial compounds in the wine are easily available from other dietary sources.
A single glass of wine can quickly – significantly – raise the drinker’s risk for atrial fibrillation, according to new research by UC San Francisco.
The study provides the first evidence that alcohol consumption substantially increases the chance of the heart rhythm condition occurring within a few hours. The findings might run counter to a prevailing perception that alcohol can be “cardioprotective,” say the authors, suggesting that reducing or avoiding alcohol might help mitigate harmful effects.
“Contrary to a common belief that atrial fibrillation is associated with heavy alcohol consumption, it appears that even one alcohol drink may be enough to increase the risk,” said Gregory Marcus, MD, MAS, professor of medicine in the Division of Cardiology at UCSF.
“Our results show that the occurrence of atrial fibrillation might be neither random nor unpredictable,” he said. “Instead, there may be identifiable and modifiable ways of preventing an acute heart arrhythmia episode.”

During the COVID-19 pandemic months of March 2020 to September 2020, U.S. alcohol retail store sales increased compared to usual trends while food services and drinking places sales decreased markedly during the same period, according to a new study at Columbia University Mailman School of Public Health. These results indicate an increase in home drinking in the U.S. The findings are published online in the journal Alcohol.
The researchers used alcohol retail store sales data of beer, wine, and liquor store (BWLS) purchases from January 1992 to September 2020 from the Monthly Retail Trade Survey, which provides sales estimates at retail and food services. Alcohol sales changes in the U.S. throughout the COVID-19 pandemic were used as an indicator of at-home drinking. Calculating variations in monthly sales enabled the authors to show annual differences in monthly BWLS sales between consecutive years from 1992 to 2020.
A new study from the World Health Organization’s (WHO) International Agency for Research on Cancer (IARC), published in the journal Lancet Oncology, has found an association between alcohol and a substantially higher risk of several forms of cancer, including breast, colon, and oral cancers. Increased risk was evident even among light to moderate drinkers (up to two drinks a day), who represented 1 in 7 of all new cancers in 2020 and more than 100,000 cases worldwide.
In Canada, alcohol use was linked to 7,000 new cases of cancer in 2020, including 24 per cent of breast cancer cases, 20 per cent of colon cancers, 15 per cent of rectal cancers, and 13 per cent of oral and liver cancers.
“All drinking involves risk,” said study co-author Dr. Jürgen Rehm, Senior Scientist, Institute for Mental Health Policy Research and Campbell Family Mental Health Research Institute at CAMH. “And with alcohol-related cancers, all levels of consumption are associated with some risk. For example, each standard sized glass of wine per day is associated with a 6 per cent higher risk for developing female breast cancer.”
Moderate alcohol intake — defined as no more than one alcoholic drink for women and two for men per day — has been associated with a lower risk of dying from cardiovascular disease when compared with individuals who abstain from drinking or partake in excessive drinking, according to a new study being presented at the American College of Cardiology’s 70th Annual Scientific Session. It’s also the first study to show that drinking moderate amounts of alcohol may be heart protective, in part, by reducing stress-related brain signals based on a subset of patients who underwent brain imaging.
“We found that stress-related activity in the brain was higher in non-drinkers when compared with people who drank moderately, while people who drank excessively (more than 14 drinks per week) had the highest level of stress-related brain activity,” said Kenechukwu Mezue, MD, a fellow in nuclear cardiology at Massachusetts General Hospital and the study’s lead author. “The thought is that moderate amounts of alcohol may have effects on the brain that can help you relax, reduce stress levels and, perhaps through these mechanisms, lower the incidence of cardiovascular disease.”
While Mezue was quick to caution that these findings should not encourage alcohol use, he said they could open doors to new therapeutics or prescribing stress-relieving activities like exercise or yoga to help minimize stress signals in the brain.
I am not a drinking guy. If I eat out once or twice a week, I might have a glass of beer with dinner, but that is it. I just don’t get anything out of alcohol. I also realize that I am in the minority. For the rest of the world ….
For several decades, government guidelines have recommended that men should limit their alcohol consumption to no more than two drinks per day. Now a panel of health experts is proposing a new guideline that would cut that limit in half.
The recommendation for women—one drink per day—would remain the same.
The new proposal comes from a panel that advises the federal government on the U.S. Dietary Guidelines for Americans, which are released every five years by the U.S. Departments of Agriculture and Health and Human Services. The new guidelines will be released later this year.
For the record, I have never had a drinking problem. At my worst, I would down a couple of beers at a meal and maybe an after dinner something. So, I don’t want to be giving an excuse to someone who is on the cusp of a drinking problem with this study.
Light to moderate drinking may preserve brain function in older age, according to a new study from the University of Georgia.
The study examined the link between alcohol consumption and changes in cognitive function over time among middle-aged and older adults in the U.S.
“We know there are some older people who believe that drinking a little wine everyday could maintain a good cognitive condition,” said lead author Ruiyuan Zhang, a doctoral student at UGA’s College of Public Health.
A team of National Institutes of Health-funded researchers at the Medical University of South Carolina has found that deactivating a stress-signaling system in a brain area known for motivation and emotion-related behaviors decreases binge drinking. The study, which was published online in February and is to appear in the May issue of Neuropharmacology, pinpoints a particular system in a specific brain region that can be manipulated to reduce harmful binge drinking.
The MUSC team was led by Howard C. Becker, Ph.D., director of the Charleston Alcohol Research Center and professor in the Department of Psychiatry & Behavioral Sciences.
“Binge drinking is one of the most common patterns in which alcohol is consumed,” explained Becker. “It’s a risky behavior, and one consequence of repeated binge drinking is increasing risk for developing an alcohol use disorder.”
Further, according to Becker, those who consistently binge drink, particularly during adolescent and college years, have almost 10 times the risk of developing an alcohol use disorder.
But how much alcohol must be consumed to qualify a drinking session as a binge?
Your Body Mass Index (BMI) can be useful in widely spread studies, but you need to be careful about relying too much on it personally. I posted on it previously and you can read Don’t get hung up on your BMI – Body Mass Index for more info.
Young Arnold Schwarzenegger as Conan the Barbarian. Six foot two inches tall, 257 pounds, BMI 33. Not what most of us would call obese.

Having obesity increases risk for cardiovascular disease and other metabolic conditions such as type 2 diabetes, but a normal BMI also does not guarantee good heart health. Here are tips based on what we know to date about metabolic health and weight: Continue reading →
At the risk of being called cannabis-crazy, I thought this item on possible negative effects of marijuana to be worthwhile.
Summary: Prenatal exposure to THC makes dopamine neurons hyperactive and increases the sensitivity to the behavioral effects of the compound during pre-adolescence. This may increase the risk of developing schizophrenia later in life. However, treatment with pregnenolone, a drug under clinical trials for ASD, cannabis use disorder, and schizophrenia, appears to correct the brain abnormalities and behavioral problems associated with prenatal cannabis exposure.

The researchers were able to correct these behavioral problems and brain abnormalities by treating experimental animals with pregnenolone, an FDA-approved drug currently under investigation in clinical trials for cannabis use disorder, schizophrenia, autism, and bipolar disorder.

As a growing number of U.S. states legalize the medicinal and recreational use of marijuana, an increasing number of American women are using cannabis before becoming pregnant and during early pregnancy often to treat morning sickness, anxiety, and lower back pain. Although emerging evidence indicates that this may have long-term consequences for their babies’ brain development, how this occurs remains unclear.Continue reading →
The debate whether moderate drinking is good, bad, or has no effect on health has been ongoing for years. Now, a new study suggests that people — especially women — who give up alcohol can experience better mental health and reach levels of well-being almost on a par with those of lifelong abstainers, according to a report in Medical News Today.
Many people drink socially at, for instance, work functions or family events. Some of us may also relish having a glass of wine or beer with our dinner at the end of a long and tiring day.
Numerous people fall into the categories of “light” or “moderate” drinkers. But is this habit harmless, or would all of us be better off abstaining from alcohol?
Even among researchers, opinions tend to vary greatly whether drinking any amount of alcohol is safe or healthful.
For instance, earlier this year, a study published in The Lancet argued that moderate drinking can increase a person’s risk of cardiovascular events.
Meanwhile, research featured this month in the journal Alcoholism: Clinical and Experimental Research suggests that older adults who occasionally drink may live longer than nondrinkers. Continue reading →
Blood pressure is the force of the blood pushed against the the wall of the arteries …
Over 500 new gene regions that influence people’s blood pressure have been discovered in the largest global genetic study of blood pressure to date, led by Queen Mary University of London and Imperial College London.
Involving more than one million participants, the results more than triple the number of blood pressure gene regions to over 1,000 and means that almost a third of the estimated heritability for blood pressure is now explained.
High blood pressure is a major risk factor for stroke and heart disease and was responsible for an estimated 7.8 million deaths worldwide in 2015. While lifestyle risk factors are relatively well-known and include obesity, smoking, alcohol and high salt-intake, high blood pressure is also highly heritable through genetics. Prior to this study however, the genetic architecture of blood pressure had not been well understood.Continue reading →
A comprehensive worldwide study of alcohol use and its impact on health concludes that the safest level of consumption is zero. The Global Burden of Disease Study 2016 has calculated levels of alcohol use and its effects on health during 1990–2016 in 195 countries.
The research, which now features in the journal The Lancet, notes that in 2016, alcohol use was responsible for almost 3 million deaths globally.
Alcohol use was the main cause of death for people aged 15–49 that year, accounting for 12 percent of deaths in men of that age.
“Our findings,” says senior study author Dr. Emmanuela Gakidou, who currently works at the Institute for Health Metrics and Evaluation (IHME) at the University of Washington in Seattle, “are consistent with other recent research, which found clear and convincing correlations between drinking and premature death, cancer, and cardiovascular problems.”Continue reading →
What we put into our system counts a lot toward our daily health and ultimate longevity. So, I thought this study on increasing seniors drinking was relevant.
Most older Americans drink alcohol. Given that this segment of the population is projected to almost double by 2050, reaching 112 million, in the future, there will likely be many more older drinkers in the United States than currently. Importantly, older individuals are more sensitive to alcohol’s effects than their younger counterparts, and are also more likely to take prescription medications that can interact negatively with alcohol, potentially leading to falls and other injuries. This study examined trends in drinking status among U.S. adults 60 years of age and older.
Researchers analyzed data from the 1997-2014 National Health Interview Surveys: 65,303 respondents 60 years of age and older (31,803 men, 33,500 women) were current drinkers; 6,570 men and 1,737 women were binge drinkers. Analysis of respondents by sex, age group, and birth cohort showed differing trends over time. Continue reading →
Anxiety seems to be a near-universal condition. In the United States alone, approximately 40 million adults – or 18 percent of the population – suffer from an anxiety disorder.
And these numbers represent only the diagnosed (i.e. reported). The actual number is likely to be significantly higher.
The truth is that society is somewhat to blame (not to negate our own sense of responsibility.) We’ve managed to build a 24/7 “constantly connected” infrastructure that has permeated into schools, businesses and elsewhere. Many people are under constant pressure to succeed; most ironically by leveraging this very infrastructure. This only exacerbates the problem.
“Prevention is the best cure” is a universal axiom within the medical community, including within the mental health sphere. Understanding what “triggers” certain symptoms or condition can – in some instances – drastically reduce the likelihood of a symptom or episode.
Here, we focus on ten established “triggers” that…
