People who live in hot climates are attracted to spicy foods since the red-hot seasonings keep them healthy. The research shows that because of the natural antimicrobials in the spices, people in warmer regions of the world benefit from eating them. Thus they developed a preference for it.
When people live in a tropical country like Thailand, for instance, have a spicy meal, the chance they spend the next few days with a bout of diarrhoea is much less than people in that region who eat mild foods.Oppositely, for country has a cooler climate like Iceland, a steak that left outside overnight might freeze. The low temperature would slow the growth of germ in the meat. As a matter of course, Icelandic dishes have left the pepper neglected.
Although there may be some medicinal value, pepper has no real nutritional value itself. So why do some people living in the normal, temperate climate still eat a large quantity of pepper?
Studies of some scientists show the pain brought from pepper could offset other pains. Some other scientists believe that the reason why humans love pepper is directed at the pain brought from pepper rather than its various advantages.
Psychologist Paul Rozin proposes:” They like the burn”. When we bite into a pepper, pepper allows our body a chance to believe that we’re doing something dangerous without any real repercussions. “Humans seem to enjoy situations in which their bodies warn them of danger but they know they are really okay,” said by Rozin.It allows us live dangerously for the moment.
