This means that using chiles in the foods of Asia is not an evolutionary type thing, although the use of other spices might be. I think that it's more of a question of what was available, and what was easily grown in the climate. >> Hi all, I agree. There is frequently a link between hot and dry in climates -- anyone in Texas??. And when it is both hot and dry, plants tend to grow more slowly, and produce less bio-mass. There are usually adaptations in arid plants that both conserve water as well as keep animals from eating them and removing precious growth, or devouring limited seeds. These adaptations include chemicals that produce strong tastes or reactions (like chiles), but others are things such as small leaves, thorns, hairy or waxy coverings, mucilaginous sap and so forth. It's probably a combination of eating what naturally grows in an area, coupled with this anti-bacterial preserving action. I have also heard that strong spicy tasting things make one sweat more, and are hence cooling. Janet. Janet.
