Chia is the ancient Mayan word for strength. Evidence suggests that chia seeds were used as a food as early as 3500 B.C. by the Aztecs, quickly becoming a cash crop 1500-900BC. Eaten alone, mixed with grains or consumed as a beverage. Aztecs used the seed in medicine; they also pressed it for its oil content, making a base for face and body paint and offered to the gods during ceremonies. The world largely overlooked its nutritional value until the 1990s.
