Dr. Axe Says it best!
The chia seed is nutrient-dense and packs a punch of energy-boosting power. Aztec warriors ate chia seeds to give them high energy and endurance. They said just one spoonful of chia could sustain them for 24 hours. Chia means “strength” in the Mayan language, and chia seeds were known as “runners’ food” because runners and warriors would use them as fuel while running long distances or during battle." - Dr. Axe
