A recent study in mice suggests that low levels of alcohol – the equivalent of about 2.5 drinks per day – can help reduce brain inflammation. High levels of alcohol, however, increase brain inflammation. This study was conducted by researchers at the University of Rochester Medical Center in New York and the results were published in Scientific Reports.
According to the researchers, low levels of alcohol improve the body’s glymphatic system, which is responsible for removing waste products from the brain and central nervous system in a process first discovered in 2012. The accumulation of these waste products, which include beta-amyloid and tau proteins, is believed to contribute to conditions like Alzheimer’s disease.
In this study, the researchers found that laboratory mice exposed to low levels of alcohol demonstrated improved glymphatic system function and reduced brain inflammation compared to a control group not exposed to alcohol. In contrast, mice exposed to high levels of alcohol experienced impaired cognitive function and motor skills.
