National Chia Day

Chia seeds, first recognized around 3500 B.C. by the Aztecs, were a staple in their diet and had many uses. Ground into flour, pressed for oil, and used in drinks, chia seeds could be stored for long periods, making them ideal for warriors and travelers. The Mayans even called it “chia,” meaning “strength”, highlighting its energy-boosting qualities. Chia’s journey through history took a pause when it was banned by the Spanish during their conquest of the Americas. However, it remained hidden in remote parts of Mexico until the 1980s, when scientists and farmers brought chia seeds back into commercial production. By the 2000s, chia was gaining recognition as a superfood, thanks in part to the vegan movement. Its nutritional benefits include omega-3 fatty acids, proteins, fibers, vitamins, minerals, and antioxidants, making it one of the most nutrient-dense foods around. Thanks to its ability to absorb liquid and form a gel, chia is used in smoothies, baking, soups, and even as a vegan egg substitute. In 2016, the rise in popularity of chia seeds led to the establishment of National Chia Day on March 23 by Mamma Chia, honoring this ancient, yet modern, nutritional powerhouse.
