My college days of eating crap 24/7 resulted in major tummy issues. After talking to a friend about it, she suggested, "why not try going gluten-free?" The idea seemed insane. No bread? No bagels? No cookies?! But after just one day, I felt a million times better. I stayed gluten-free for six years and, as if it wasn't hard enough missing out on some my favorite foods, it was the rude and insensitive comments from gluten lovers that really bit my biscuit. No matter what their reason for ditching wheat, barley, and rye, here's what you should never say to someone giving up gluten.
