The number of people going gluten-free has increased dramatically in the 21st century, but do you know how to successfully go gluten-free? Know whether bagels or eggs make a better breakfast choice, or whether your favorite fast-food treats are safe to consume? Any idea which snacks you can reach for without noshing on gluten -- are pretzels, peanuts or cookies gluten-free?
For something relatively small, gluten can do a whole lot of damage. This protein found in wheat, rye and barley helps give food its shape and hold it together. It's the reason dough is so stretchy and fun to knead when baking. It's also a major health threat for people with celiac disease, who experience significant damage to the small intestine when they eat gluten. This autoimmune disease isn't completely understood, but scientists estimate that it may affect as as many as one percent of the population.
Of course, celiac disease isn't the only reason to go gluten-free. While there's still plenty more research to be done on the topic, many people eliminate gluten in an attempt to cure various health problems -- from skin rashes to weight gain.
Yet going gluten-free isn't as simple as giving up bread. This plant protein can be found in all kinds of foods, many of which you wouldn't expect. Think you can tell a gluten-containing food from a gluten-free one? Take our quiz to find out!
