Given that Americans consume over 100 million donuts each year, they don’t really need an excuse to devour the gooey fried treat. However, if you are among the minority that does, you are in luck, because Friday, June 2, is National Donut Day. Celebrated annually on the first Friday of the month, the holiday’s origin can be traced back to Salvation Army workers who volunteered to help injured US troops during World War I (WWI).
