Some People Do Not Taste Salt Like Others
Low-salt foods may be harder for some people to like than others, according to a study by a Penn State College of Agricultural Sciences and Food scientist. The research indicates that genetic factors influence some of the difference in the levels of salt we like to eat.
Those conclusions are important because recent, well-publicized efforts to reduce the salt content in food have left many people struggling to accept fare that simply does not taste as good to them as it does to others, pointed out John Hayes, assistant professor of food science, who was lead investigator on the study.
Diets high in salt can increase the risk of high blood pressure and stroke. That is why public health experts and food companies are working together on ways to help consumers to lower salt intake through foods that are enjoyable to eat. This study increases understanding of salt preference and consumption.
The research involved 87 carefully screened participants who sampled salty foods such as soup and chips, on multiple occasions, spread out over weeks. Test subjects were 45 men and 42 women, reportedly healthy, ranging in age from 20 to 40 years. The sample was composed of individuals who were not actively modifying their dietary intake and did not smoke cigarettes. They rated the intensity of taste on a commonly used scientific scale, ranging from barely detectable to strongest sensation of any kind.
"Most of us like the taste of salt. However, some individuals eat more salt, both because they like the taste of saltiness more, and also because it is needed to block other unpleasant tastes in food, " said Hayes. " Supertasters, people who experience tastes more intensely, consume more salt than nontasters do. Snack foods have saltiness as their primary flavor, and at least for these foods, more is better, so the supertasters seem to like them more.
However, supertasters also need higher levels of salt to block unpleasant bitter tastes in foods such as cheese, Hayes noted"For example, cheese is a wonderful blend of dairy flavors from fermented, milk, but also bitter tastes from ripening that are blocked by salt, " he said. "A supertaster finds low-salt cheese unpleasant because the bitterness is too pronounced.
Hayes cited research done more than 75 years ago by a chemist named Fox and a geneticist named Blakeslee, showing that individuals differ in their ability to taste certain chemicals. As a result , Hayes explained, we know that a wide range in taste acuity exists, and this variation is as normal as variations in eye and hair color.
"Some people, called supertasters, describe bitter compounds as being extremely bitter, while others, called nontasters, find these same bitter compounds to be tasteless or only weary bitter, " he said. "Response to bitter compounds is one of many ways to identify biological differences in food preference because supertasting is not limited to bitterness. "
In paragraph 2, John Hayes points out that______.
选项
A、it is good to health to eat food without salt
B、many people reject low-salt food completely
C、many people accept low-salt tasteless food reluctantly
D、food with reduced salt tastes better
答案
C
解析
本题考查的是对文章细节的理解。题目是:在第二段中,约翰·海斯指出了 。选C的依据是短文的第二段内容,很多人因为食物中的含盐量降低,所以必须做出很大努力(struggling)去适应,而低盐食物对于他们来说,口味很不好(fare that simply does not taste as good to them),选项C中的accept reluctantly(勉强接受)表达了这层意思,所以是正确的选项。A.吃无盐食物对身体有好处。B.有些人完全反对含盐量低的食物;D.含盐量低的食物更好吃。这三个选项均是错误的。
