According to a recent study by researcher Michael A. Collins, of the department of molecular pharmacology and therapeutics at Loyola University Medical Center in Maywood, Illinois, drinking in moderation can help prevent Alzheimer's disease and memory problems in general.
However, researchers emphasize the "moderate consumption" of alcohol, the equivalent of a daily glass of wine, or 1 to 2 glasses of beer or 1 small shot of liquor for women; and to double these measures for men.
In this study, moderate drinkers were 23% less likely to develop symptoms of memory problems or Alzheimer's disease. These benefits were seen in 14 of the 19 countries surveyed, including the US
It is not known exactly how that moderate alcohol consumption does reduce the risk of memory problems, but alcohol may have anti-inflammatory effects. And, precisely, it is the inflammation of the brain one of the main symptoms of Alzheimer's disease, the most common form of dementia in the population. Inflammation is also one of the symptoms in heart disease, vascular lesions in the brain, diabetes, rheumatoid arthritis, and some cancers.
"This study is not the last word, but it offers the most completed picture," says study researcher Michael A. Collins, who adds that "low levels of alcohol may have anti-inflammatory effects on the immune system, on the heart and on the brain.”
On the other hand, the wine turned out to be more protective than beer or spirits, according to this new report. But most studies do not differentiate between types of alcohol.
Viña Ardanza Reserva 2005 is a Rioja from the La Rioja Alta cellar based on tempranillo and garnacha of 2005 and 13.5º of alcohol strength.
Marqués de Murrieta Reserva 2010 is a red wine from this DO: Rioja based on carignan and cannonau of 2010 and presents an alcohol content of 14º.
