We all know that Americans should be eating more fruits and vegetables. But there’s a big difference between eating a handful of carrots or a tangerine, and munching on some leafy greens. The CDC recently ranked 47 of America’s most common fruits and vegetables, and 41 out of 47 tested were determined to be “powerhouse” sources of nutrition. 

Each of the fruits and vegetables were analyzed on a scale that measures the amount of fiber, protein, potassium, and vitamins. 

But Mason jar, Mason jar on the wall, who is the fairest (and most nutritious) vegetable of them all? As it turns out, the answer is, “all of the vegetables that are green and leafy.” Here are the most nutrient dense vegetables, according to the CDC.
