If you're a big wine drinker, we have the best news ever for you! Enjoying a glass of wine every night doesn't only help you relax after a busy day, but also reduces inflammation and helps your brain clear away toxins, including those tied to Alzheimer's disease. These findings were unrelieved in a new study published in the journal Scientific Reports.
“Prolonged intake of excessive amounts of ethanol is known to have adverse effects on the central nervous system. However, in this study we have shown for the first time that low doses of alcohol are potentially beneficial to brain health, namely it improves the brain's ability to remove waste,” explained Dr Maiken Nedergaard, lead author and co-director of the Center for Translational Neuromedicine at the University of Rochester Medical Center in the United States.

Past studies have found that low alcohol consumption has heart health and cancer benefits
A number of past studies suggest that consuming low amounts of alcohol has health benefits such as reduced risk of heart disease
as well as some cancers. Therefore, the findings of this new study add to previous research, showing that the health benefits of low amounts of alcohol extend to reduced risk of Alzheimer’s disease.

New study associates low levels of alcohol with reduced risk of Alzheimer’s disease
Dr Nedergaard and his team studied the brains of mice exposed to both acute and chronic amounts of alcohol and found high levels of a molecular marker for inflammation. However, the brains of those exposed to the equivalent of two-and-a-half drinks per day showed less inflammation. Furthermore, their brain were more efficient at removing waste via the brain’s unique cleaning process known as the glympathic system.
Dr Nedergaard and his team concluded that the process was effective in eliminating two toxic proteins that are strongly associated with Alzheimer’s disease, namely beta amyloid and tau. “Studies have shown that low-to-moderate alcohol intake is associated with a lesser risk of dementia
, while heavy drinking for many years confers an increased risk of cognitive decline
,” he said. “This study may help explain why this occurs. Specifically, low doses of alcohol appear to improve overall brain health.”
The next time you feel guilty for pouring yourself a glass of wine after a long day, remind yourself that it may help stave off Alzheimer’s disease!
