The claim of "alcohol has no health benefits" seems to be overall leaning towards being a FALSE claim according to reliable scholarly sources. However...the claim is then restated as a question that reads "are there zero health benefits to drinking alcohol in any amount". These are two different claims. The claim I will be focused on answering is the initial one that claims 'alcohol has no health benefits'.
The source titled 'The Health Benefits of Moderate Alcohol Consumption: A Review of the Literature' by Cynthia Baum-Baicker makes three claims about how alcohol can have health benefits.
"Alcoholic beverages are food, containing approx. 7 calories per gram of ethanol. Beer contains small percentages of the recommended daily allowance of vitamins and significant proportions of the recommended daily allowance of trace metals and minerals. Wine, while possessing significantly smaller amounts of vitamins and minerals than beer, has considerably more iron. Both beer and wine have a favorable potassium to sodium ratio." (Baum-Baicker).
"Coronary heart disease (CHD) seems to have a negative association with regular alcoholic beverage use" (Baum-Baicker).
"Dry non-sweet wines and diluted distilled spirits have been recommended in the treatment of diabetes" (Baum-Baicker).
According to yet another source, 'Beyond Ischemic Heart Disease: Are There Other Health Benefits From Drinking Alcohol?', this reliable source also mentions how moderate alcohol consumption may have health benefits as well.
"The weight of evidence suggests that low-level alcohol consumption offers some protection against ischemic stroke. The evidence that moderate alcohol consumption protects against diabetes and gallstones is also fairly strong" (Ashley).
According to yet another source 'To Your Health: Re-examining the Health Benefits of Moderate Alcohol Use', "although excessive alcohol use and alcohol misuse contribute to a broad range of health problems, recent research indicates that moderate alcohol consumption may in fact be beneficial" (Sayed).
With all research in mind, the claim 'alcohol has no health benefits' is FALSE, as there are benefits found to be tied especially with moderate alcohol consumption. On the other hand, the question of 'are there zero health benefits to drinking alcohol in any amount' is slightly a different question as the any amount part is crucial to consider. While there are health benefits when drinking in moderate amounts, the health benefits diminish if one abuses alcohol or drinks much more frequently than a moderate consumer. Yet, in the grand scheme of things, there are minor health benefits that come along with drinking an appropriate amount of alcohol.
