Here is a look and find challenge for you: find something green in this food advertisement (both are from the same food joint).
Kinda monochromatic, aye? Even the cabbage bowl doesn't look like it has much cabbage. Yes, beige food, composed of carbs, sugar, and some sort of light colored protein (usually chicken) make the brain feel all warm and fuzzy inside. We want. We eat.
We want beige food because our ancient ancestors couldn't have it. They were stuck with a more high fiber cuisine for the most part.
Where has this fulfillment of our desire for beige food gotten us though? Why hasn't our brain sped up the evolution on that one, and figured out that excessive amounts of beige fatty food IS NOT GOOD FOR THE BODY. Hello brain! Don't be so Paleolithic.
Post Script: Beige is a weird word, but Troglodyte is kinda awesome.
