Researchers may have discovered a perfect material of dieting—low fat cake and cheese.British researchers say they have created a protein (蛋白质) that can replace fat perfectly.
The proteins will enable food producers to remove much of the fat used in their products but without reducing product quality.
Funded by team from University of Edinburgh,the researchers have produced the modified (调整了的) proteins that easily break down and therefore work nearly the same as the fats do during food production.
“We’ve paved the way for the development of modified proteins that can be used to produce a wider range of appealing low-fat foods,”said Dr.Steve Euston,who led the research.“The result could be important for health benefits,as well as a reduction in the burden on the National Health Service (NHS) caused by many weight-related health problems.”
Protein-for-fat substitution (替代品) is not a completely new idea,but to date it has been limited to products such as yogurts.
In cheeses and cakes it has proved less successful in ensuring the original taste and texture fundamental to consumer satisfaction,mainly because proteins could not mimic the behavior of fats closely enough.
By studying the proteins’ chemical structure,the team has developed a detailed understanding of how proteins behave when they are heated or go through other food producing processes.
The proteins could encourage development of a wider choice of low-fat foods,helping consumers to eat more healthily and reducing weight-related health problems.
The team has achieved particularly promising results in using proteins to replace eggs,which is commonly used in bakery items.
Such substitution not only cuts fat content;because eggs can be subject to sharp changes in price.It could also cut the cost products and so encourage consumers to eat more healthily.

(2024安徽“江淮十校”四月联考)
Do you think you are more intelligent than your parents and grandparents?According to James Flynn,a professor at a New Zealand university,you are!Over the course of the last century,people’s IQ test scores have gotten steadily higher—on average,three points higher each decade.This improvement is known as the “Flynn effect”,and scientists want to know what is behind it.
IQ tests are designed to measure general intelligence rather than knowledge.Flynn believes that intelligence partly comes from our parents and partly is the result of our environment,but the improvement in test scores has been happening too quickly to be explained by heredity(遗传).So what has occurred in the 20th century to help people achieve higher scores?
Scientists have proposed several explanations for the Flynn effect.Some suggest that the improved test scores simply reflect an increased exposure to tests in general and the learning of test-taking techniques that help us perform better on any test.Others have pointed to better nutrition.Babies now are born larger,healthier,and with more brain development than in the past.Another suggested explanation is a change in educational styles,with teachers encouraging children to learn by discovering things for themselves rather than just memorizing information,which improves their problem-solving skills.
Flynn has limited the possible explanations after carefully examining test data and discovering that the improvement in scores has taken place in only certain parts of the IQ test.Test-takers are not doing better on the maths or vocabulary sections of the test;they are doing better on the sections requiring reasoning and problem solving.For example,one part of the test shows a set of shapes,and test-takers must find the patterns and connections between them.
According to Flynn,this visual intelligence improves as the amount of technology in our lives increases.Every time you play a computer game,you are exercising exactly the kind of thinking and problem solving that helps you do well on one kind of intelligence test.So are you really smarter than your parents?In one very specific way,you may be.
