Moderate consumption of alcohol against heart disease

Those who drink alcohol in moderation (about one drink a day or less), 14-25% are less likely to get heart disease than those who don't drink alcohol at all, according to a study led by Professor William Ghali of the University of Calgary, published today in the British Medical Journal.

The first paper, led by Paul Ronksley of the University of Calgary emphasized that a balance is needed between public messages that say consuming large amounts of alcohol is bad for you, and the other message is that drinking alcohol excessively can benefit health.

Partner paper led by Dr. Susan Brien, also from the University of Calgary, found that moderate consumption of alcohol (in the size of one drink a day or 15 g of alcohol per day for women and reaching the range of 30 g of alcohol per day for men) turned out to be good for health. They say that moderate amounts of alcohol significantly increase the level of good cholesterol circulating in the body and this has a protective effect against heart disease.

Brien and his colleagues said that their study strengthened the case that there was a causal relationship between alcohol consumption and a reduction in heart disease.

The authors of the two papers acknowledged that a number of previous studies concluded that moderate alcohol consumption had been linked to a decrease in heart disease. However, they said that the research had expired and needed new material. Professor Ghali said that the research carried out by his team was the most comprehensive.

Ghali and his colleagues looked back at 84 studies of alcohol consumption and heart disease. They compared alcohol drinkers with non-drinkers and their results related to heart disease, death from heart disease, incidence of stroke and death from stroke.

In a partner study, Brien and his colleagues looked back at 63 studies and investigated alcohol consumption with physical signs for heart disease such as cholesterol, inflammation levels, fat cells and blood vessel conditions. They also assessed the influence of the types of alcohol consumed such as wine, beer and spirits).

Interestingly, the research conducted by Brien concluded that alcoholic content provides health benefits and not the type or type of alcoholic beverages (wine, beer or spirits) taken.

Professor Ghali concluded that the debate between the impact of alcohol on heart disease should now be centered on how to integrate this evidence into clinical practice and public health messages.

He added: ''with teh public health messeage now there may be an urge to beter commuinicate to the public that exceessive consumption of alcohol has overal health benefits that exceed teh risks in a group of patienits. Such strattegies need to be accompeanied by proper study and impact of errors. "
