Heavy alcohol consumption is associated with increased risks of hypertension, stroke, heart rhythm disturbances, dementia, accidents, injury, violence, and damage to the heart, liver, and pancreas. Alcoholism is a medical condition typically signified by a physical compulsion to drink and can result in other health concerns as well as social or behavioral issues. In some studies, moderate red wine consumption has been linked to increased levels of high-density lipoproteins or good cholesterol, which may be helpful in preventing blood clots that can reduce the risk of heart attack or stroke. Regular moderate drinkers are less likely to get kidney stones — 41% less likely for those who drink beer, 33% for wine drinkers. Part of the reason may be that alcohol, like caffeine in coffee and tea, makes you pee more often. Drink too much, though, and you can get dehydrated, and that increases your risk of kidney stones along with other health problems.
Wine drinkers would clearly be the healthiest subset insofar as they smoke less and engage in more aerobic exercise. But why would non-drinkers smoke more than wine-drinkers and exercise less than any of the other groups? Upon further investigation, only 27% of the nondrinkers said they had never been drinkers and 27% provided no information about their past drinking or non-drinking habits. The vast majority of alcoholics are smokers — who very often continue to smoke while abstaining from alcohol. This would also be true of non-alcoholic ex-drinkers who stopped drinking because of health problems. It would be no surprise to find higher rates of cardiovascular disease among nondrinkers who smoke more than light drinkers — an effectnot due to the difference in drinking behavior. Not surprisingly, the investigators discovered that the lifelong teetotalers among the nondrinkers had lower rates of smoking.

Only then can we understand the true size of the risk to individual drinkers. But the health risks associated with alcohol consumption — even at the recommended “moderate” levels — far outweigh any minor potential benefits, the study’s authors benefits of alcohol insist. The researchers did find that low levels of alcohol consumption (less than the study’s definition of a standard drink per day) may offer some modest protection against heart disease and, perhaps, against stroke and diabetes.
It’s possible that moderate drinking lowers stress enough to have a positive effect on heart health. A study of over 2000 older Norwegians (aged 70-74) has found that those who consumed chocolate, wine, or tea had significantly better cognitive performance and lower risk of poor cognitive performance than those who did not. Those who consumed all 3 studied items had the best performance and the lowest risks for poor test performance. The associations between intake of these foodstuffs and cognition were dose dependent, with maximum effect at intakes of around 10 grams a day for chocolate and around 75–100 ml a day for wine, but approximately linear for tea. The effect was most pronounced for wine and modestly weaker for chocolate intake.
Heavy alcohol consumption has been found to increase the risk of cancer at a number of sites . Heavy alcohol consumption is consistently and dose-dependently associated with increases in risk of Alcohol detoxification cancers of the mouth, pharynx, larynx, esophagus, liver, colon, rectum, and breast . Moreover, the combination of smoking and alcohol results in even more dramatic increases in cancer risks .
Should You Try Going Through A ‘dry January’ Without Alcohol?
Light drinking increases social conversation and reduces inhibition among virtually all people who consume alcoholic beverages on social occasions. The effects are particularly dramatic for some people suffering from high anxiety. Yet the same doses of ethanol producing these seemingly stimulant effects usually reduce performance on complex tasks. It is a common assumption that light drinking can stimulate thinking and that heavier drinking has only temporary harmful effects on brain function. Brain damage to alcoholics is attributed to malnutrition rather than to neurotoxicity of ethanol. Acetaldehyde is then further metabolized in mitochondria by the enzymeacetaldehyde dehydrogenase to acetic acid — which can be metabolized into carbon dioxide and water with a release of energy. Daily drinking can increase liver metabolism of ethanol by as much as a third.
However, a recent study in perimenopausal women found that moderate alcohol intake was associated with improved BMD independent of various lifestyle factors, including smoking status, fruit and vegetable intake, and physical activity level . Some large prospective cohort studies have found wine drinkers to be at lower risk of CHD than beer or liquor drinkers (22, 38-40), but others have found no difference . Moreover, some studies have observed a decreased risk of myocardial infarction or CHD in predominantly beer-drinking populations in the Czech Republic , in Germany , and in Japanese men residing in Hawaii .
A 2011 meta-analysis of prospective cohort and case-control studies found that moderate consumption of wine or beer was associated with a decreased risk of non-fatal vascular events . This analysis did not associate drinking liquor with cardiovascular benefit, although the authors noted that binge drinking — which is known to increase CHD risk — was apparent in several of the included studies . Significant reductions in CHD risk have been associated with moderate consumption of wine, beer, and liquor. Red wine contains the phenolic compound resveratrol — although usually at variable and low concentrations — as well as flavonoids like procyanidins; these compounds could provide additional cardiovascular benefits beyond those associated with ethanol. Beer also contains polyphenolic compounds that might confer some cardioprotection . The development of CHD is characterized by the formation of cholesterol-laden plaque in the arteries , vascular inflammation, and clot formation . HDLs transport cholesterol from tissues, including arterial walls, back to the liver for elimination or recycling.
Health Risks Of Moderate Alcohol Consumption
For those with mild cognitive impairment, drinking speeded up the rate of decline. Another, large long-running, study found that, although non-smokers who consumed moderate amounts of alcohol were less likely to have a stroke than non-drinkers, this didn’t apply to smokers. “The health risks associated with alcohol are massive,” said Emmanuela Gakidou of the Institute for Health Metrics and Evaluation at the University of Washington in Seattle and the senior author of the study, in a released statement. “Our findings are consistent with other recent research, which found clear and convincing correlations between drinking and premature death, cancer, and cardiovascular problems. We’ve been told for years that drinking alcohol in moderation — having a glass of wine or a beer with dinner each day — is not only harmless to our health, but may actually protect our heart and thus help us live longer. Research suggests men who consume one or two alcoholic drinks per day have a lower death rate from coronary heart disease than abstainers. The recommended safe intake for men is no more than three units of alcohol a day, or 21 units per week.
Serious liver disease has been found to develop in approximately 10% of those who consume more than 60 grams per day of alcohol (4.3 drinks/day). Women are more susceptible to serious alcoholic liver disease than men , and individuals with hepatitis C infection have an increased risk https://sootthaengball.com/hazelden-addiction-treatment-center/ of alcoholic liver disease . Current estimates are that about one in eight women (12.4%) in the US will develop breast cancer at some point in her lifetime . Although there are many risk factors for breast cancer, alcohol consumption is one of only a few modifiable risk factors.
Like a village idiot chasing a wallet on a string, epidemiologists typically take self-reporting at face value and fail to distinguish between ex-drinkers and lifetime teetotalers — calling both « abstainers ». Not surprisingly, the abstainers are deemed to be less healthy than light drinkers. Epidemiology is widely used to establish health benefits of alcohol benefits & hazards of various substances, including ethanol. And few substances demonstrate the perils of poor study design, confounding proxy variables and bad judgement to the extent of ethanol in the hands of epidemiologists. Acontrolled clinical trial of ethanol would berandomized ,double-blind , longitudinal andlong-term .
If you’re in good shape, moderate drinking makes you 25% to 40% less likely to have a heart attack, stroke, or hardened benefits of alcohol arteries. This may be in part because small amounts of alcohol can raise your HDL (« good » cholesterol) levels.
Even light and moderate alcohol consumption increases cancer risk in individuals, especially with respect to squamous cell carcinoma of the esophagus, oropharyngeal cancer, and breast cancer. The concentration of alcohol in blood is measured via blood alcohol content . The amount and circumstances of consumption play a large part in determining the extent of intoxication; for example, eating a heavy meal before alcohol consumption causes alcohol to absorb more slowly. Hydration also plays a role, especially in determining the extent of hangovers. After excessive drinking, unconsciousness can occur and extreme levels of consumption can lead to alcohol poisoning and death (a concentration in the blood stream of 0.40% will kill half of those affected). The median lethal dose of alcohol in test animals is a blood alcohol content of 0.45%. This is about six times the level of ordinary intoxication (0.08%), but vomiting or unconsciousness may occur much sooner in people who have a low tolerance for alcohol.
- In a 12-year study of more than 38,000 male health professionals, those who consumed alcohol at least 3-4 times weekly had a risk of myocardial infarction that was 32% lower than men who drank alcohol less than once weekly .
- The risk of cognitive impairment was reduced among women whose daily alcohol consumption was less than 40 grams and among men who drank less than 80 grams.
- When the results of 28 prospective cohort studies were combined in a meta-analysis, adults who consumed an average of 25 grams/day of alcohol had a risk of CHD that was 20% lower than adults who did not consume alcohol .
- Higher levels of alcohol consumption showed an increased risk of cognitive impairment when compared with both abstainers and moderate drinkers.
- Similarly, in a 20-year study of more than 120,000 men and women, those who reported consuming 1-2 alcoholic drinks daily had a risk of death from CHD that was 30% lower than those who did not drink alcohol .
- More recent data from two large prospective cohort studies conducted in the US suggest that the magnitude of CHD risk reduction associated with moderate alcohol consumption may be closer to 30%.
Alcohol expectations are beliefs and attitudes that people have about the effects they will experience when drinking alcoholic beverages. They are just largely beliefs about alcohol’s effects on a person’s behaviors, abilities, and emotions. Some people believe that if alcohol expectations can be changed, then alcohol abuse might be reduced. Men tend to become more aggressive in laboratory studies in which they are drinking only tonic water but believe that it contains alcohol. They also become less aggressive when they believe they are drinking only tonic water, but are actually drinking tonic water that contains alcohol. Some studies have suggested that one glass of red wine a day can be good for health, leading some people to believe that benefits derive from all types of alcohol.
There is reason to believe that ethanol might have some benefit for coronary heart disease for those with low blood HDL cholesterol. But the benefit can usually be achieved more safely by other means of raising HDL cholesterol. Brain atrophy and damage to the hippocampus by ethanol in even the lowest doses should be alarming to rational persons. Whatever the reputed health benefits of ethanol, the health costs are vastly greater. By my values, the possibility of brain damage makes any mild cardiovascular benefit pale by comparison — especially when there are so many other ways to improve cardiovascular health.
