Why do you think people
who live in some hot countries eat very spicy(辛辣的)food? Is it because the spices make the food
taste better? Is it just because their parents and grandparents and
great-grandparents liked hot food，or is there some connection between spices and healthy food?
Researchers from Cornell University think
that it is because spice plants have some important chemicals(化學(xué)物質(zhì))．These chemicals can kill
bacteria(細菌)which
spoil food．
“Most common spices can kill 75 to 100
percent of the bacteria in food，”explains one of the scientists．The bacteria grow more easily and spoil food more quickly at higher
temperatures．For
this reason，it is
more difficult to keep food from spoiling in hot climates，
Do you like your food spicy? Your answer
probably tells something about the country you come from．If you like spicy food，it is possible that hundreds of
years ago，when
there were no fridges，people in your country started using spices to keep the food from
spoiling．The
traditional spicy dishes helped those people to live longer，healthier lives．Today，in a time of fridges，the spices just make the food
taste good．
