So … Ezra Klein did the math on last week’s school lunch story, which created the “pizza is a vegetable” meme, and found that if you put the USDA-recommended one-eighth of a cup of tomato paste side-by-side with a half a cup of fruit, the results are actually pretty comparable. How about that? “Measuring fruit and vegetable servings by volume is a bit of an odd convention in the first place,” Klein notes. “When it comes to calories and nutrients, they’re really all over the map.” Problem is, of course, that the pizza is still attached to the bread and the cheese, while the apple is attached to nothing but goodness.
