Hey, good news, movie fans: a cup of air-popped popcorn contains 3.5g of fiber. That's actually pretty good. Just know that all health benefits are lost when you order a barrel of the stuff, drench it in movie theater "I can absolutely believe it's not butter," and chow down on it while watching Michael Bay's latest crime against humanity.
Whole-wheat English muffin pizzas
English muffin pizzas are the best snack ever, and whole-wheat English muffins are high in fiber and low in cholesterol and completely free of trans fats and I can't worry about proper grammar and syntax now because I'm gonna go make some.
Before I do that, just a heads up: according to Harvard, whole grains help to lower cholesterol, maintain steady blood sugar levels, and could even protect against some cancers. You just have to pay attention to be sure you get the real thing, since the labeling standards for whole-grain products need some more work.
Just make sure you use more beans than meat. That way you'll get a good dose of fiber. And maybe don't throw it on top of a hot dog.
