Do u know what staple means?? Also moderation except when it comes to FONT SIZE BRAH 
staple foods are staple foods only to poor people in poor countries. you live in the first world. you can eat rice AND wheat AND corn AND potatoes. so eat them all in moderation if you want to, and don't worry about it.
lol about the font size. just be glad i put it at 90 instead of 150. 
lol. well put it as a question to the audience, which carb src is your staple? Im sure there are ppl who prefer one to the other. for instance i know our crossfitter palaeolithic friends dont like grains but are quite fond of starch sources like potatos and sweet potatos. And to them i'd point out how superier wheat is in aggregate nutrient content. to say wheat is more nutritious is a fact based on the above chart. or maybe there is something special about paleo potatos like lance reports which makes thruster kips smoother and more effective? Who the fuck nows.
My point is if you need a goto carb src, and ur not sure which is is gd or dont care which, then u cud have rice, corn or potatoes or whatever but from a strictly nutritient pov, wheat is more nutrient dense than those other lesser srces.
for me, ive avoided wheat for a while for some reason. my main carb sources are frm milk and rice, fruit (but not counting that), and preworkout potatos. and having done some research (2 seconds on wikipedia), ive realised i shud be eating more wheat and less rice, cos rice is inferior. i prefer rice cos it tastes good tho
btw LBBS I know you will you say dont have to eat just one, you can eat a combo of sources. which is completely true and i agree, if it fits your macros/cals then go for it. and I do that like you said, we have a lot of food choice. i typically might eat fruit+sugar+milk+maize+tubers +wheat+rice during a wk. but talking about day to day nutrition, i'll have trouble sticking to my cals and macros if im eating all those daily. so if i have a limited number of cals and macros, then im going to carefully choose the sources which gives me the biggest nutritional punch day to day. and of course every now and then i'd have the other sources too for variety. i hope that makes sense
