http://news.nationalgeographic.com/news/2005/11/1111_051111_spicy_medicine.htmlSherman's research shows that people in warmer regions of the world benefit from eating spicier foods, because spices are natural antimicrobials. Food-borne pathogens and parasites are more prolific in warmer climates, and spices can kill or inhibit their growth.
When people in a country like Thailand, for instance, eat a spicy meal, they are much less likely to spend the next day with a bout of diarrhea than people in that region who eat bland foods.
"Humans do what makes them feel good, and they learn from each other," Sherman said, adding that people in hot climates learned that spicy food is less likely to make them sick and thus developed a preference for it.
"The simple mechanism is they felt better after eating food that was spicy, and since they felt better they learned to like that stuff," Sherman said. "Over time, word-of-mouth spread the news."....
....In all countries studied, spice use was greater overall in dishes from warmer regions.
http://www.scientificamerican.com/article.cfm?id=cooking-up-bigger-brainsThen, one cool fall evening in 1997, while gazing into his fireplace in Cambridge, Mass., and contemplating a completely different question—“What stimulated human evolution?”—he remembered the chimp food. “I realized what a ridiculously large difference cooking would make,” Wrangham says. Cooking could have made the fibrous fruits, along with the tubers and tough, raw meat that chimps also eat, much more easily digestible, he thought—they could be consumed quickly and digested with less energy. This innovation could have enabled our chimp*like ancestors’ gut size to shrink over evolutionary time; the energy that would have gone to support a larger gut might have instead sparked the evolution of our bigger-brained, larger-bodied, humanlike forebears.
In the 10 years since coming on his theory, Wrangham has stacked up considerable evidence to support it, yet many archaeologists, paleontologists and anthropologists argue that he is just plain wrong. Wrangham is a chimp researcher, the skeptics point out, not a specialist in human evolution. He is out of his league. Furthermore, archaeological data does not support the use of controlled fire during the period Wrangham’s theory requires it to.
hot food allows for faster digestion
Because hot ice cream keeps falling off the cone.or very cold?
Heh! I doubt it would make a measurable difference at all. Because soon after you swallow it, it will drop to body temperature.
And besides, that would have nothing to do with the question the poster asked.
Because hot ice cream keeps falling off the cone.
well my argument stems from this:
we like our food hot because for our body it allows for better/faster digestion (breakdown of food particles by enzymes), which gives us pleasure faster.
Also I would like to invoke the Pavlov dog experiment, where a dog was given an association with a bell and food being served, after a while only the bell was ringed and the food was not there yet the dog still produced saliva and whigged its tail in anticipated of food because of association.
So we are like dogs by an association have come to see hot food as more pleasurable. And yes there is also the fact that hot food also releases scent easier.
Nope, you're heading up the wrong path completely. Although we feel satisfaction after having eaten, the MAIN pleasure comes during the eating itself - not later while we are digesting it. (Unless you happen to be built totally backwards from the rest of the human race - which, in your case, I suppose IS possible.)
well since you going that way. I don't know how it works for you grandpa with all the organs not doing their job too well.
I am saying that Pavlov's dog felt pleasure from hearing the bell because of association with food that gave it pleasure.
So an old man who barely can chew properly hahahhaha...still has some memories (if not for Alzheimer's) of the pleasure associated with food that is hot, thus the tastebuds make more saliva and pleasure is there.
It seems likely to me that the preference is cultural, rather than biological. We like hot foods because our foods tend to be cooked, and that led to certain cultural expectations and practices that seeped into our culture and inform our tastes.
The most popular flavors of ice cream in the late 18th and early 19th centuries were savory flavors: beef ice cream, oyster ice cream (Dolley Madison had quite a taste for the oyster ice cream), etc. Today most people in the U.S. would reject that out of hand, but in other parts of the world, fish ice cream, tongue ice cream, even reports of horsemeat ice cream (in Japan).
We seem to like things at extreme temperatures (without venturing into any painful extremes) perhaps because of the sensation generated by the extreme difference and because we have certain expectations. (That said, I do not know that I prefer a hot or cold ham sandwich to a room temperature one.) The thing is, though, I am reticent to say that that preference is universal (let alone biological) just because I identify with it.
The mastery of fire and, therefore, cooking did not become widespread until around 100KYA. Our species was fully established in its current form at that time, with all organs in the sizes and proportions they are today. So we had reached this point in our evolution without cooked food.A chimp researcher has proposed that learning to cook food spurred our evolution.
Hot food has more flavor. The taste particles are given higher energies which allow them to escape and be tasted or smelled.
I think a more interesting question is why we like hot (spicy) food.
