New "fake fat" products appeared on store shelves in the United States recently, but not everyone is happy about it. Makers of the products, which contain a compound called olestra, say food manufacturers can now eliminate. Critics, however, say the new compound can rob the body of essential vitamins and nutrients (营养物) and can also cause unpleasant side effects in some people. So it's up to consumers to decide whether the new fat-free products taste good enough to keep eating.
Chemists discovered olestra in the late 1960s, when they were searching for a fat that could be digested by infants more easily. Instead of finding the desired fat, the researchers created a fat that can't be digested at all.
Normally, special chemicals in the intestines(肠)"grab" molecules of regular fat and break them down so they can be used by the body. A molecule of regular fat is made up of three molecules of substances called fatting acids.
The fatty acids are absorbed by the intestines and bring with them the essential vitamins A, D, E and K. When fat molecules are present in the intestines with any of those vitamins, the vitamins attach to the molecules and are carried into the bloodstream.
Olestra, which is made from six to eight molecules of fatty acids, is too large for the intestines to absorb. It just slides through the intestines without being broke down. Manufacturers say it's the ability to slide unchanged through the intestines that makes olestra so valuable as a fat substitute. It provides consumers with the taste of regular at without any bad effects on the body. But critics say olestra can prevent vitamins A, D, E and K from being absorbed. It can also prevent the absorption of carotenoids(类胡萝卜素), compounds that may reduce the risk of cancer, heart disease, etc.
Manufacturers are adding vitamins A, D, E and K as well as carotenoids to their products now. even so, some nutritionists are still concerned that people might eat unlimited amounts of food made with the fat substitute without worrying about how many calories they are consuming.
We learn from the passage that olestra is a substance that______.
A.contains plenty of nutrients
B.renders foods calorie-free while retaining their vitamins
C.makes foods easily digestible
D.makes foods fat-free while keeping them delicious
The oldest and simplest method, then of describing differences in personality was to classify people according to types, and such a system is called a Typology. A famous example of this method was set forth in Greece about the year 400 BC.A physician named Hippocrates theorized that there were four fluids, or humors, in the body. Corresponding to each humor, he believed, there existed a definite type of personality.
The four humors were blood, yellow bile, black bile, and phlegm. A person in whom all four humors were in perfect balance had a harmonious personality. If a person had too much blood, he was called sanguine(血红色), or cheerful and optimistic. Someone with too much yellow bile was choleric, or irritable and easily angered. Too much black bile made a person melancholy, or depressed and pessimistic. An oversupply of phlegm caused a human being to be phlegmatic, or slow and unfeeling. Scientists have long since discarded Hippocrates’ fluid theory. But the names of the humors, corresponding to these temperaments, have survived and are still useful, to some extent, in describing personality.
Other features of people, such as their faces and physics, have also been used to classify personality. Today, however, personality theories and classifications may also include factors such as heredity(遗传特征), the environment, intelligence , and emotional needs. Psychology, biology, and sociology are involved in these theories. Because of the complexity of human personality, present day theories are often very different from one another. Psychologists vary in their ideas about what is most important in determining personality.
