Gluten-free flours might be taking up a bit more of your grocery store shelves every passing year, but the one that tends to be the easiest to find is still white rice flour. It’s a great substitute for all-purpose white flour in baking since it creates a light and delicate texture for cakes, muffins, and pastries. It’s also way cheaper than, say, coconut flour. The downside? White rice flour has just two grams of protein per serving. Even all-purpose flour — often criticized for its subpar nutritional value — squeezes in four grams.

A 2015 study in Digestive Diseases notes that a gluten-free diet is the only accepted treatment for celiac disease, but it can lead to multiple nutritional deficiencies of macro- and micronutrients. The best solution? A rotation of gluten-free grains to check off all the necessary complex carbs, fiber, and — you guessed it — protein.
