I'm reading "Born to Run" and learned that the Tarahumara peoples of Mexico eat Chia seeds to give them energy. In the book they mix the seeds with water, some lime juice and a bit of sugar... to make Iskiate.
What would be the purpose of this particular preparation? Is it simply for taste, or does the addition of these ingredients (water, lime juice, and sugar) have some impact on either the short-term physical or long-term health effects?
