Things with flour in them (white or wheat) are the most common culprits when you’re avoiding gluten. The following foods are among the more obvious edibles and beverages that are gluten packed:
Bagels
Beer
Bread
Cookies, cakes, and most other baked goods
Crackers
Pasta
Pizza
Pretzels
All these foods and drink are made with wheat or wheat flour, so they’re pretty easy to identify. But you need to watch out for foods that contain oats as well because, although they don’t contain gluten, the way they’re processed makes them inedible for gluten-intolerant folks.
