This article on CNN.com is all about how, in the future, it may be possible for people to buy food based on their personal body chemistry a bit easier. For example, someone like me who can not digest potatoes and things as easily as my Irish boyfriend, might go for the foods marked with a blue sign. While, someone who needs to lower their cholestorol, might go for foods marked with a green sign.
Wouldn't that make life a heck of a lot easier???
