Chia seeds are featured as the main ingredient in several healthy recipes such as protein bars, baked goods, and smoothies. The seeds are not only highly nutritious but also offer great texture and flavor to food. They have become a popular superfood in the healthy community with a long list of benefits.

Chia plants produce numerous white or purple flowers that are clustered in spikes at the end of the stem. The plants are native to Central America, particularly Mexico and Guatemala. They have also been planted in some areas in South and North America including the southwestern United States and western Mexico. Chia means "oily" in the Aztec language of Nahuatl.
Salvia columbarriae, which is also referred to as "golden chia," is an annual plant found in North America. The plant was an important food source for Native Americans and can be found in several US and Mexican states including New Mexico, California, Utah, Nevada, Arizona, Baja California, and Sonora. The plant grows up to approximately 2 ft high and has clusters of blue or purple flowers. The preferred habitat for the plant is at elevations below 8,200 ft in undisturbed and dry chaparral or coastal sage scrub
