Alcohol consumption is dangerous and expensive, for both individuals and communities. The scientific evidence is strong, as I’ll show you. Before I do that, I should acknowledge and comment on a conflict of interest. That is, of course, my Mormon culture. Like most Mormons, I was educated to avoid alcohol. Known as the “ Word of Wisdom,” the health code of The Church of Jesus Christ of Latter-day Saints specifically prohibits consumption of alcohol. Because of that, I have surely inherited a bias against alcohol. But don’t dismiss my thoughts on this topic too quickly. Like most Mormons, I was also educated to abstain from coffee and tea. And I do abstain. But that’s only for symbolic reasons, as an expression of cultural solidarity. For health reasons, I still consume the main bioactives of coffee and tea through dietary supplements. Symbolism is also a reason that I abstain from alcohol. But, in contrast to coffee and tea, alcohol gives me many additional reasons to abstain. To be fair, there may be some positives to alcohol consumption. In particular, it facilitates aspects of sociality in many cultures — at least until it doesn’t, paradoxically. It may also provide small cardiovascular health benefits when consumed moderately — although those benefits may be attributed to polyphenols that are readily available from non-alcoholic sources. But, as I think you’ll clearly see, the positives of alcohol consumption are vastly outweighed by the negatives. That’s enough preaching from me, at least for now. I’ll let the scientists preach. Below are some quotes from peer-reviewed studies that have described the negatives of alcohol consumption. There are also direct links to the studies themselves, for your deeper consideration. These are just a representative sampling. If you want to read more, check the content at the links for many more links to related studies. Health Costs of Alcohol Consumption “Alcohol dependence and alcohol abuse or harmful use cause substantial morbidity and mortality. Alcohol-use disorders are associated with depressive episodes, severe anxiety, insomnia, suicide, and abuse of other drugs. Continued heavy alcohol use also shortens the onset of heart disease, stroke, cancers, and liver cirrhosis, by affecting the cardiovascular, gastrointestinal, and immune systems. Heavy drinking can also cause mild anterograde amnesias, temporary cognitive deficits, sleep problems, and peripheral neuropathy; cause gastrointestinal problems; decrease bone density and production of blood cells; and cause fetal alcohol syndrome. Alcohol-use disorders complicate assessment and treatment of other medical and psychiatric problems.” ( Alcohol-use disorders ) “It has been estimated that alcohol abuse represents the world’s third largest risk factor for disease and disability; it is a causal factor of 60 types of diseases and injuries and a concurrent cause of at least 200 others. Liver is the main organ responsible for metabolizing ethanol, thus it has been considered for long time the major victim of the harmful use of alcohol.” ( Alcoholic disease: liver and beyond ) “Alcohol impairs function of neurons and glia, disrupting a broad array of functions including neuronal survival, cell migration, and glial cell (astrocytes and oligodendrocytes) differentiation.” ( Human alcohol-related neuropathology ) “The decrease in bone mass and strength following alcohol consumption is mainly due to a bone remodeling imbalance, with a predominant decrease in bone formation.” ( Alcohol and bone: review of dose effects and mechanisms ) “A causal association has been established between alcohol consumption and cancers of the oral cavity, pharynx, larynx, oesophagus, liver, colon, rectum, and, in women, breast; an association is suspected for cancers of the pancreas and lung.” ( Alcohol and cancer ) “Several factors contribute to alcohol-induced cancer development (i.e., carcinogenesis), including the actions of acetaldehyde, the first and p ...
