A new study shows that drinking 2 cups of hot chocolate a day improves blood flow to the brain by 8% in elderly people. This increase in blood flow improves memory and could help prevent dementia. I love drinking hot chocolate in the winter time, especially when I was a kid before I started drinking coffee, so now I have a good excuse to keep drinking it! My favorite hot chocolate is from Dunkin Donuts, mmmmm! Are these results enough to convince you to indulge in the winter months? What kind of hot chocolate is your favorite?
