Risks associated with MRAC: no definitive answer
While there is no doubt about the fact that alcohol abuse is harmful to one’s health, the potential risks of MRAC are less well known and sometimes controversial. Aside from the increased risk of injury and accident (after only one or two drinks, in some cases), the most frequently noted diseases are breast cancer, colorectal cancer and cirrhosis of the liver.
Some studies show a link between alcohol and breast cancer among both pre-menopausal and post-menopausal women.
Similarly, while some research has shown a connection between drinking and the risk of developing colorectal cancer, there is no proven causal link or even association between low alcohol consumption and colorectal cancer.
As for liver disease, the amount of alcohol at which the risk increases is not precisely known. Unlike other cases involving the negative effects of alcohol, where regular drinking is less harmful than the occasional consumption of large amounts of alcohol, the opposite is true for liver diseases: it would appear that the daily drinkers are more at risk than the occasional bingers.
The effects of MRAC on health vary from one person to the next. At this time, it is not possible – and it will likely never be possible – to make recommendations that apply to all people.
Since alcohol provides protection essentially against cardiovascular diseases, which are very rare among young adults, no positive impact on mortality has been observed in this group. MRAC may protect them later against this type of disease, but this remains to be shown.
The beneficial effects of alcohol on health can be observed at low levels of consumption and among certain groups of people. In the case of a number of diseases, while some studies are encouraging, more research is necessary in order to confirm the positive impact of alcohol.
Among post-menopausal women and men over 40, MRAC is associated with reduced mortality due to the protective effects of alcohol on fatty deposits in the blood vessels.
