 I grew up in a family of engineers and studied to be a scientist in college. But along the way, I decided to follow my dream of cooking. And now I'm a professional chef. But I still think a lot about science, especially the science of food. Take this bacon lettuce and tomato sandwich. It's a classic. It's easy to make as it is to eat. But in reality, the sandwich came a long, long way before it ended up in this kitchen. Depending on where you live, the average ingredients may have traveled hundreds or even thousands of miles to get to you. And even then, this food isn't guaranteed to be eaten. In the US alone, we waste 150,000 tons of food every day. What if everything were a little easier and a lot less wasteful? Right now, IBM researchers are transforming the food chain as we know it. Within five years, farmers will have more information than ever before. Food will make it to our plates faster. Waste will be dramatically reduced. Food-borne illnesses will drop. Even our kitchen trash will look different. Simply put, in five years, a lot's going to change, both for this BLT and for every other meal we eat.
