[Alcohol as a health risk: new recommendations for dealing with alcohol]

Chronic alcohol consumption is related to more than 200 disorders. Up until now, limits for low-risk use of alcohol were 24 g/ day for men and 12 g/ day for women. Recent epidemiologic studies have shown that any alcohol may be harmful.

The aim of this review is to reassess the health risk of alcohol.

There is a linear relationship between the amount of alcohol consumed and mortality risk. No risk-free dose of alcohol exists. However, health risk varies not only with the amount of alcohol consumed but also with target organs, as well as individual genetic and non-genetic factors such as smoking, medication use, exposure to environmental toxins, and pre-existing disease that deteriorates with alcohol use. High-risk groups for the damaging effect of alcohol include children and adolescents, old people, and women. Diseases that are affected by alcohol even at a low dose include arterial hypertension, cardiac arrhythmia (extrasystole, arterial fibrillation), some liver diseases (non-alcoholic fatty liver disease, hepatitis C, porphyria) as well as breast cancer. For these disorders, a threshold of low risk does not exist. Finally, in addition to breast cancer, alcohol is a risk factor for cancer of the oral cavity, the larynx, pharynx, oesophagus, liver, and colorectum. During pregnancy alcohol is completely forbidden.

There is no such thing as a risk-free dose of alcohol.
