With so many food fads going in and out of the public consciousness every day, it can be hard to figure out what's really good for you and what's just trendy. Timeless pantry staples to consider are "ancient grains." These are grains like quinoa, amaranth, teff, spelt and khorasan wheat. They get their name not only because they've been around for centuries, but also because they've been unchanged in their composition. The added benefit of eating ancient grains is that since they've been part of the human diet for hundreds of years, even the ancient grains that are technically not gluten-free can often be tolerated by those with gluten intolerance.
