In the 1980s, chia saw its rise to fame in the U.S. in the form of Chia Pets – clay figurines, such as sheep, that grew grass-like fur. But you can add chia – which is packed with fiber, calcium, thiamin, niacin, and phosphorous – to foods and beverages to incorporate a mild nutty flavor or provide a tapioca-like texture. "You can buy chia seeds in some stores, and some gluten-free manufacturers are using it in cereals and bread products," says Thompson.
