What foods can you not eat raw?

jpud

For instance, is there any veggie or seed/nut or bean that would ever be harmful if consumed raw? Is there any raw food that you can have too much of.....you know like they used to say about spinach before they realized the calcium in it negated the acidity of the oxalic acid to have any harmful effects? That kind of stuff.

What should I watch out for in my diet? Any suggestions for very simple beginnings to add a few entrees to my table that are raw?
