There was a piece not long ago about food allergies in the context of bullying.  Said article was a bit vague on the actual cause of the bullying.  One imagines it happens as the main population of kids observes the does and don'ts of the allergic kid.  "What, no glutens?  What are you, a freak?  Don't want cheese, can't eat pizza, what's up with that?"

But we are not all cut from the same cookie cutter.  We are complex and different.  And certain people can eat certain things, and other people just shouldn't.  Take wheat, for example.  I fall in with the belief that blood type is, at least, a factor.  A type O cannot be the omnivore able to handle domesticated grains that a type B is.

And one wonders, do let's say blood types give us what might be construed as a particular kind of general attitude, a way of filtering (eating) reality?  Observations emerge.  Maybe kids, people in general, note the distinction of behavior between the food allergy group and the main which goes beyond eating habit.

Are Os built better for long sustained efforts like hunting, generally agreeable, non judgmental to cooperation?  Are Bs (blood type of Mongol hordes) shrewder, better at market interactions than their more gullible and accepting brethren, built better for the speed and constant doings of a modern world full of decisions over tiny matters?
