Chia is an edible seed that comes from the desert plant Salvia hispanica, grown in Mexico dating back to Mayan and Aztec cultures. "Chia" means strength, and folklore has it that these cultures used the tiny black and white seeds as an energy booster. That makes sense, as chia seeds are a concentrated food containing healthy omega-3 fatty acids, carbohydrates, protein, fiber, antioxidants, and calcium. Chia seeds are an unprocessed, whole-grain food that can be absorbed by the body as seeds (unlike flaxseeds). One ounce (about 2 tablespoons) contains 139 calories, 4 grams of protein, 9 grams fat, 12 grams carbohydrates and 11 grams of fiber, plus vitamins and minerals.
