Moderate alcohol consumption associated with improved health in older people

A paper published in Age & Ageing, the scientific journal of The British Geriatrics Society, has expanded on earlier research that moderate alcohol consumption could lower levels of inflammation, and help to combat cardiovascular disease and frailty in older people.

A paper published in Age & Ageing, the scientific journal of The British Geriatrics Society, has expanded on earlier research that moderate alcohol consumption could lower levels of inflammation, and help to combat cardiovascular disease and frailty in older people.

The paper, written by researchers at The National Institute on Ageing in the US, highlights the statistical correlation between moderate alcohol consumption and down regulation of C-reactive protein - an important biomarker of inflammation.

The researchers said that ageing is associated with progressively higher levels of inflammation and evidence has shown that individuals with raised levels of C-reactive protein are at higher risk for developing age-related medical conditions such as frailty, poor physical performance, low muscle strength and cardiovascular disease.

Using data from the Women's Health Study Djousse, which included over 26,000 participants, researchers found that individuals who drank between 5 to 14.9 grams of alcohol per day - the equivalent of up to 1.86 units, a bottle of beer or small glass of wine - had a significantly lower risk of cardiovascular disease compared to those who abstained from alcohol or drank 15 grams of alcohol per day or more.

Markers of inflammation were 21% lower in moderate alcohol users compared to abstainers or occasional drinkers, and 13% lower when compared to heavy drinkers.

Although the findings from the study suggest that moderate alcohol consumption is associated with reduced inflammation, the reason for this is not yet fully understood and more research is needed.

Despite the limitations of the research, researchers said that the potential beneficial effects of moderate alcohol consumption should be taken into account when reviewing public health recommendations.

Dr. Luigi Ferrucci, scientific director at The National Institute on Ageing and one of the authors of Age & Ageing, said: "While evidence is growing that regular consumption of small amounts of alcohol, especially as red wine, may have beneficial effect on health, there is still some doubts that this protective association found in epidemiological study is attributable to abstention for alcohol of individuals who are already ill. Longitudinal studies are needed to shed further light on this question, which has important public health implications."
