As my second-grade daughter and I recently cozied up in front of a movie with a huge bowl of popcorn, she asked me if popcorn is healthy. Her friends told her it isn’t, but we make it a lot as a snack, so she was confused. This perplexity isn’t surprising, because popcorn can be one of the least nutritious snacks or one of the healthiest.
Popcorn found at most movie theaters is made with unhealthy oils, artificial butter, food dyes and tons of salt. In fact, a study by the Center for Science in the Public Interest found that some medium-sized movie theater popcorn buckets contain up to 1,200 calories and 60 grams of saturated fat. Whoa! Microwavable bags aren’t much better; they, too, usually include unhealthy oils, artificial flavors and colors, and preservatives.
Stove-top and air-popped varieties of popcorn can be an improbably nutritious snack, if cooked with the right oil, tossed with the right toppings and enjoyed in the right ratios. Popcorn kernels are whole grains with the germ and the bran intact, which is where the majority of nutrients lie. These little kernels are fiber-rich, low in calories and full of antioxidants.
They also contain some water. When the kernels are heated, the water molecules vibrate until the pressure pops the shell. Fresh kernels contain more water, and will pop faster and often into bigger pieces. So pitch that popcorn in the back of your cabinet.
