Belgian chocolatier Dominique Persoone snorts cocoa powder off his Chocolate Shooter in his factory in Bruges, February 3, 2015. When Belgian chocolatier Dominique Persoone created a chocolate-sniffing device for a Rolling Stones party in 2007, he never imagined demand would stretch much beyond the rock 'n' roll scene. But, seven years later, he has sold 25,000 of them. Inspired by a device his grandfather used to propel tobacco snuff up his nose, Persoone created a “Chocolate Shooter” to deliver a hit of Dominican Republic or Peruvian cocoa powder, mixed with mint and either ginger or raspberry.

Some foods have significantly more Calories than others but what does the difference actually look like. Each of the photographs below represents 200 Calories of the particular type of food; the images are sorted from low to high calorie density. When you consider that an entire plate of broccoli contains the same number of Calories as a small spoonful of peanut butter, you might think twice the next time you decide what to eat. According to the U.S. Department of Agriculture, the average adult needs to consume about 2000 – 2500 Calories to maintain their weight. In other words, you have a fixed amount of Calories to "spend" each day; based on the following pictures, which would you eat?
