a. cultivated currency
Domesticated in the valley of Mexico as early as 2,700 B.C.,
chia seeds served as a primary staple food of the Nahuatl
(Aztec), Mayan, Incan and other indigenous peoples.
Its cultivation is referenced in the Florentine Codex—the twelve volume
research manuscript including more than 2,000 natively-drawn illustrations
meant to document the culture and natural history of the Aztec
people. The Mendoza Codex, a similarly themed tome also
referenced the plant's cultivation and that it could be found in
roughly 80% of the Aztec states at the time of the writing.
Also inferred from the codices is the notion that these seeds were so highly prized
that they were used as currency as well as offered to gods along with other life-sustaining crops.
One spoon of seed in water was used to supply sustenance for an entire day of
hard labor. Related to the Nahuatl words Chiapan, meaning "river of chia" (possibly
in relation to its broad cultivation); and chia, meaning "energy" or "strength".
Traditionally and presently used by the Tarahumara and Chumash of Chihuahua, the
seed is roasted, crushed, and mixed with water for a gel of extremely high
nutritional value used as performance food. In California, Arizona, Mexico,
Guatemala and Nicaragua it was, and is, mixed with a lemonade. The ground seed
meal was called pinole.
b. absorbing the nutrition
Nutritionally speaking, chia seed packs a wallop. Aside from
consisting of about 30% protein, chia seed delivers an abundance
of vitamins A, B, D, E and K. They also contain alpha-linolenic
and linoleic acid, essential fatty acids that the body cannot
manufacture on its own. In terms of other nutrients and
minerals, the list is lengthy. A run down by alphabetical order:
calcium, copper, iodine, iron, magnesium, manganese, niacin,
phosphorus, potassium, silicon, sodium, sulfur, thiamine, and
zinc. Finally, chia seed is the richest plant-based source of
omega-3 available.
Chia seed is also an excellence source of soluble fiber. In
fact, due to its hydrophilic properties it can absorb up to 12
times its volume in water. This activity has two benefits.
First, it helps to keep the body hydrated, which is important
for proper cellular metabolism and renewal. Secondly, it reduces
transit time in the gastrointestinal tract while enhancing the
absorption of vitamins and minerals.
The hydrophilic properties of chia seed also permit the
formation of hydrophilic colloids, a mucilaginous substance
similar in appearance to gelatin. This is the same benefit
obtained from eating raw vegetables versus cooked, only it’s not
necessary to swallow a bunch of chia seeds in order for this
event take place. As you’ll learn in a moment, all that’s needed
is a container of water.
