Need a refresher on the gluten free diet? These grains are safe: rice, soy, corn, potatoes, tapioca, buckwheat, arrowroot, amaranth, millet, quinoa, sorghum and teff. When plain, you can also eat: fruits, vegetables, milk, meat, eggs, beans, oil, wine and distilled alcohols like vodka and gin.

As for what’s off limits, “no wheat, rye, barley and (mainstream) oats” in practice means, no (wheat) flour, pasta, croutons, bread, cookies, and “hidden” gluten sources like soy sauce, beer, and licorice. (But don’t despair, there ARE specialty gluten free versions of these products available!) Beyond these basics, even the most experienced shopper can be stumped by mysterious ingredients like “guar gum.”
