A couple of beers or glasses of wine a day can reduce your risk of dementia.

South Korean scientists monitored the health of four million people for eight years and came to the conclusion that daily, but small alcohol consumption is associated with a lower risk of developing dementia. Those who drank one can of beer (0.33 liters) or a glass of wine per day had a 21% lower risk of developing dementia than non-drinkers. Those who drank twice as much - 17% lower. Those who consumed three or more servings of drinks - 8% higher. Scientists suggest that the fact is that alcohol in small and moderate amounts reduces inflammation in the brain and thickens the blood, helping it to circulate better.
