1 cup of cooked quinoa = 17 Nacho Cheese Doritos
Quinoa: deceptively spelled, deceptively full of calories. You've got to watch portioning here, because a cup of the cooked stuff is around 220 calories, or the equivalent of 17 OG Doritos. Uncooked quinoa is even more caloric, but we're going to assume you're normal and not eating this stuff raw.
1 cup of almonds = Three Snickers bars
Really, most nuts are secret calorie bombs. (A notable exception? Cashews.) But one of the worst offenders is the almond. Just a cup of these guys will cost you 800+ calories, which is the same tally you'd get from multiple Snickers. And those already have nuts.
One mango = four Oreos
While bananas (110) and pears (100) are probably a little more caloric than you expected, the mango puts both to shame with its 200 count. Consuming just one is the same as making a decent dent in a sleeve of original Oreos, which require far less paring.
