You know what they say: keep your friends close, keep your enemies closer. Why not apply that axiom to food?
For example, I'm allergic to nuts so this article makes sense for me to study. Where are the new places people are even thinking of putting nuts? I need to be like a Nut ninja, stealthfully cutting danger off at the pass.
What are you allergic to? What are the new food trends? Where are the new places they are considering putting gluten or dairy or eggs or whatever gives you hives? It behooves you to find out, to become your own food detective, food historian or foodie.
Keep your friends close; keep your enemies closer. Good stuff.
