You may already know that the food you eat is made up of lots of tiny particles that your body breaks down and digests to give you energy. But what if our food had other kinds of particles in it, say, very small nanoparticles that could change the color of your soda, for example? Scientists are looking at the idea of putting just those kinds of particles into our food for a number of reasons: to make it easier to take medicines, better deliver nutrients, and yes — even to change the flavor or texture of what you’re eating as you eat it! It’s still a long way off until we’d be able to buy anything like this in a grocery store, but imagine that someday companies might sell a kind of candy that would let you decide for yourself what flavor and color it would be. Now that’s some fun food!
