The “Review of Evidence on Alcohol and Health” from NASEM does not make recommendations. Instead it summarizes the available evidence published in the past five to 15 years on how moderate alcohol consumption is linked to lactation, weight, cancer, cardiovascular disease, neurocognition and all-cause mortality. Moderate drinking is defined as two drinks per day for men, or one drink per day for women. The committee’s conclusions are based on associations, so the report doesn’t explain whether alcohol consumption is directly responsible for the outcomes.
