One of the wonders of Mexico is the richness of the culture and the diversity of nature. Chia seeds are just one magnificent example. It is an edible seed that comes from the desert plant Salvia hispanica, a member of the mint family that grows abundantly in southern Mexico. In pre-Columbian times they were a main component of the Aztec and Mayan diets and were the basic survival ration of Aztec warriors. I’ve read that one tablespoon was believed to sustain an individual for 24 hours. The Aztecs also used chia medicinally to stimulate saliva flow and to relieve joint pain and sore skin.
Chia is very rich in omega-3 fatty acids, even more so than flax seeds. And it has another advantage over flax: chia is so rich in antioxidants that the seeds don’t deteriorate and can be stored for long periods without becoming rancid. And, unlike flax, they do not have to be ground to make their nutrients available to the body. Chia seeds also provide fiber (25 grams give you 6.9 grams of fiber) as well as calcium, phosphorus, magnesium, manganese, copper, iron, molybdenum, niacin, and zinc.
Another advantage: when added to water and allowed to sit for 30 minutes, chia forms a gel. Researchers suggest that this reaction also takes place in the stomach, slowing the process by which digestive enzymes break down carbohydrates and convert them into sugar.
Chia has a nutlike flavor. You can mix seeds in water and add lime or lemon juice and sugar to make a drink known in Mexico and Central America as “chia fresca.” As with ground flax seeds, you can sprinkle ground or whole chia seeds on cereal, in yogurt or salads, eat them as a snack, or grind them and mix them with flour when making muffins or other baked goods.
