We know that the liver can detoxify small amounts and this seems to be a limit of 12 units per week for men and women. (1 unit = 100mls wine = 250mls standard beer = 25mls spirit). If you drink less than this it is unlikely you will come to harm, but it still won’t be good for your health.
In some circumstances it is better to drink no alcohol, such as liver disease and pregnancy. Others, such as those with high blood pressure or inflammation should stick to very low intake such as less than 2-7 units per week.
