Food first is the most prudent way to go.

Since I have played so many different villages now, I like to challenge myself to get the science tech first.

In my first games I always got food, then science, then meds. Doing it that way, I ususally have a Master Scientist or three before I get the science tech, so that when I do get it, those points just skyrocket.
