It is well-known that food which is full of fat isn't good for your heart. Australian researchers tested people with asthma(哮喘)before and after a high-fat meal or a low-fat meal. Then they found that the high-fat meal increased inflammation(炎症)and reduced the lung functions.
30 non-obese people with asthma took part in the study, as well as 16 obese adults. The non-obese volunteers received either a high-fat or low-fat meal, while the obese ones were all given a high-fat meal. The low-fat meal was 13 percent fat.
Four hours after the meal, the researchers found that the airway inflammation increased a lot and lung function was affected in those who had the high-fat meal. And these people saw just a 1 percent improvement in their lung function when they used their inhalers(吸入器)to treat asthma.
"If these results can be tested again by further research, this suggests that reducing the amount of fatty food one eats may be useful for managing asthma," said the study's lead author, Lisa Wood, at the Hunter Medical Research Institute in New Lambton. "The number of people in the world with asthma has increased greatly over the past few decades. "
Dr Thomas Leath, director at Scott & White Healthcare in Texas, said, "Eating fatty food can lead to obesity, and fat can certainly cause a small amount of inflammation. "He doubted whether the effect on lung function was great enough for people to notice, but said the study provided one more reason why people shouldn't have high-fat diets.
A. And one reason is the high-fat Western diet.
B. Inflammation can be either short-lived or long-lasting.
C. But now a new study suggests that fatty meals may affect the lung function too.
D. But I'm surprised that one meal could do this.
E. The high-fat meal was 50 percent fat.
F.People are generally considered obese when their body mass index is over 30 kg/㎡.
G. Those who ate the low-fat meal saw a 4.5 percent improvement.
