- Apr 27 4:39 PMA majority of humans have very restricted diets, however humankind has
a very wide diet - if just the staple plant Families are looked at we
have: Gramineae (rice, wheat, maize), Araceae (taro), Euphorbiaceae
(cassava), Solanaceae (potatoes), Arecaceae (sago), Moraceae
(breadfruit), Musaceae (plantain), Amaranthaceae (amaranth,
goosefoot), Fabaceae (soy), Cannaceae (canna), Marantaceae (arrowroot)
. . .
Most of the staples are (or have been) the mainstay of their culture,
sometimes to the extent that specific maladies caused by deficiency
are associated with several. Most cultures which rely strongly on one
staple have developed cooking techniques or use admixture plants that
alter the chemical structure of the staple or add the missing
nutrients - when these staples have been relied on outside of their
home range disasters have occurred.
There are still a huge number of people subsisting on single staples,
with the absolute minimum of potherbs, salt or "stock" for survival.
In times of famine, the demand for staples has been shown to increase;
as less variety of food becomes available, more people need more of
Most people, who rely on a staple for day to day nutrition, usually
opt for meat or fish as an addition - given the choice. Finances do
not normally allow this, even if the family produces edible animals
they are more valuable as capital than food - a chicken might buy a
week of the local staple or make one or two meals.
Around the world the relative prices of staples are increasing as
valuable cash-crops are grown where the staples used to grow.
Apologies for the digression :)
