We all grew up knowing the "food pyramid" by heart, but it wasn't easy to apply to the real world because it was all based on servings. If all food came in packages by the serving, then everything would make sense, but that's not the case. Food site CHOW's handy visual guide for popular fruits and vegetables attempts to fix that problem.
Fruits like oranges, peaches, and pears are no surprise, since they're roughly the "fist-sized" portion that the serving generally sticks to, but other fruits aren't so easy to pin down, and it's usually the ones that are the most fun to eat. So, just how many grapes make up a "serving" of fruit? Turns out it's 32.
Vegetables can be even harder than fruit, but the guide makes it easy (now, if only eating certain vegetables were as easy). Asparagus lovers will be happy to know that it only takes an average of four spears to make a serving—but broccoli haters will be displeased to know that it takes 16 baby trees to get the same result.
The guide is available as a handy, two-page PDF, so you can post it right up on the fridge. CHOW also recommends you go straight to the CDC's website and use their calculator to find out exactly how many servings of each that you need on a daily basis, and to use the guide as a reference point until you get the hang of it.
