【推荐1】Many people travel to different places in the world by air. Usually it takes a long time, perhaps half a day, for passengers to stay in the plane for a long time. So airlines offer passengers food. But it is common that they feel bad about food taste. Some passengers complain about the food to the airline companies , and some others even refuse to eat them. Do you agree?

To solve this problem, airlines try hard to improve their food. They would like to do so because they don’t want to lose customers.

However, according to scientific research, part of the reason why plane food tastes bad is that at high altitude we can not taste things as well as we do on the ground. Also scientists have found that our noses become very dry even before a plane takes off. As the plane moves up, the change in air pressure reduces one third of the sensibility of our taste buds（味蕾）. So our taste buds become senseless (没有知觉的).   The sad fact, however, is that our noses don’t know it.

All of these help explain why food on the plane tastes so bad. They also help explain why airlines choose to offer passengers salty and spicy food. Without doing so, the food would be tasteless.

Now there are many researches on this. According to one of them, some volunteers are asked to lie with their feet higher than their heads for weeks. And scientists write down their feelings about food taste.

Though scientists try their best, it is not as easy as they thought. Because they can’t deal with the special environment successfully, such as the change in air pressure, making food taste good is still hard for them.

The 67-year-old woman cannot eat meat because it causes her uncomfortable feeling in stomach. "Every time I go out, I meet the same situation," she says. "I tell them 'I don't eat meat, so in the soup, please don't include chicken or duck. But when they serve it, there's always a little bit of meat."

Ms. Zhang says it's sometimes just a problem of communication. "For example, when they serve green beans, there is a bit of meat in the dish. I say 'how come there's still meat?'" she says. "And the waiter look and say, 'Oh that? That shouldn't be a problem!'"

Ms. Zhang is among 50 million Chinese who are believed to be vegetarians, about 4 per cent of the 1.3 billion population. Traditionally in poorer times, meat was a luxury (奢侈). But times are changing, and with them, so are cultural attitudes (态度).

Belle Zhang from Beijing is another vegetarian who has also had difficulties at restaurants. "At home of the noodle restaurants here, even if you order a bowl with no meat, the soup is always made from meat," she says. "We vegetarians can always taste it!" She says a recent trip with friends up to China's Northeast proved more difficult than other parts of the country.

"The food in the Northeast is really meaty, so there wasn't a single dish we ordered that was vegetarian, " she says. "Every plate on the table in one way or another had a little bit of meat in it."
