To assess the impact of moderate consumption of different types of alcohol on health, an international team of scientists collected data from 446 thousand people 40-69 years old from the British Biobank. All participants reported how much they drink weekly beer, cider, wine, champagne and spirits per week.
The volunteers were monitored for seven years: data on mortality and diagnosed diseases, including coronary heart disease, stroke and malignant neoplasms, were entered into the Biobank.
Analysis of the data showed that the consumption of beer, cider and spirits were associated with higher rates of mortality, cancer and cardiovascular disease.
At the same time, in people who drink 8-11 glasses of red wine a week a week, the risk of coronary heart disease is reduced by 40% compared to teetotalers and those who like to “put the collar”. The British had the same advantages, who consume no more than 4-5 glasses of white wine and champagne.
The biggest discovery was that non-alcoholic red wine had the same effect as regular wine: Scientists found that drinkers were also less likely to develop coronary heart disease.
This suggests that all the benefits of red wine are not related to alcohol, but to polyphenols – powerful antioxidants found in abundance in grapes, according to lead author Rudolph Schutte of the University of England Ruskin.
The scientist added that conclusions about the benefits of alcohol often follow from a comparison of health and mortality among drinkers and teetotalers, which is not very correct.
“The non-drinker control group will also include people who abstain from alcohol due to health problems. Therefore, comparisons with them may erroneously indicate the benefits of alcohol, ”explained Schutte.
