As others have pointed out, there are a bunch of food processing companies around like the Magic Bullet. They don't really care where you get your food from, but if they can convince you to buy/grow more whole food instead of juice or apple sauce or whatever it is you normally buy from the store, they stand to profit because people still want their juice. There are also knife companies, garden care, etc.
