I remember seeing a program about this on 20/20: http://abcnews.go.com/GMA/MedicalMinute/story?id=451163&page=1 They don't have these sprinkles on the market yet, but maybe it's something we could formulate on our own, or just make a point of making our food more flavorful and more importantly more FRAGRANT (or smelly!). It seems that it's all about stimulating smell as much as taste, and smells don't have calories (or grams of carbs). They even list the smells/flavors they used: "The 12 different crystals or powders are divided into two groups: sweet crystals to put on sweet or neutral foods, and salty crystals to put on everything else. The sweet food crystals come in the flavors of cocoa, spearmint, banana, strawberry, raspberry and malt. The salty crystals come in the flavors of taco, cheddar cheese, parmesan cheese, ranch dressing flavor, horseradish and onion."
