âA gluten-free diet is a diet that does not include gluten, a protein found in wheat, rye, and barley,â says Tricia Thompson, RD, a dietitian based in Manchester, Mass., who focuses on developing gluten-free eating programs for people with celiac disease.
Studies show gluten-free diets can be deficient in fiber, iron, folate, niacin, thiamine, calcium, vitamin B12, phosphorus and zinc, she said. You can eat a healthy diet without gluten, but you have to be very knowledgeable, and most people aren't, Tallmadge said. People who go gluten-free may feel better because, to avoid the protein, they end up cutting out desserts and junk foods, thus losing weight. They mistakenly attribute that to their gluten-free decision, Tallmadge said.
