As the old saying goes, you are what you eat. The foods you eat obviously affect your body’s performance. They may also influence how your brain handles its tasks. If it handles them well, you think more clearly and you are more emotionally stable. The right foods can help you concentrate, keep you motivated, sharpen your memory, speed your reaction time, defuse stress, and perhaps even prevent brain aging.
【R1】________We are encouraged to eat fat-free foods and to drain fat away from fried foods. To understand its psychological benefits, however, we have to change the paradigm for how we think about fat.
The first step is gaming a better understanding of fat. Instead of conceiving of it as one thing, we have to recognize it as several discrete types of a similar compound. Not every fat is your enemy. Fats, of the right kinds and in the right amounts, are among your best friends. It is smart to commit to a balanced-fat diet, not to a no-fat diet.
【R2】________Most foods that contain fat contain both kinds, in varying proportions.
Foods that are high in saturated fats include meat, butter, and other animal products. In general, saturated fats are solid at room temperature. Foods high in unsaturated fats include vegetable oils, nuts, and avocados. Unsaturated fats, if separated out, are usually liquid at room temperature.
【R3】________Saturated fat in moderate amounts poses no problem. In general, you will be fine if less than 20 percent of the fats you consume are saturated. Beyond that level, saturated fat may promote heart disease and perhaps some types of cancer. A diet high in saturated fat can also make you depressed and antisocial and impair your general mental performance. Unsaturated fats should make up the bulk of your fat intake. But beware.
Unsaturated fats are especially high in calories and could cause weight problems. The smart approach is to keep your overall fat intake low and make sure that most of it is in the form of unsaturated fats.
【R4】________Fat in food is broken down into chemicals called fatty acids. The body uses them for many purposes. They go into all hormones. They are critical to body metabolism. And they are part of the outer membrane (膜) of every cell in the body, including those in the brain. You need these fatty acids in order to stay physically healthy and mentally sharp.
Of the many fatty acids the body uses, two are called "essential fatty acids" (EFAs). Your diet must contain foods that provide them, because the body cannot make them on its own. The most important are omega-3 fatty acids. They are crucial for the proper development of the human brain. All brain-cell membranes need to refresh themselves continually with new supplies of omega-3s.
【R5】________In one well-respected study, premature infants were fed either standard American infant formula or breast milk. Results showed that the children given breast milk had significantly higher IQs. The researchers also compiled data on the children for eight years after the initial feeding period. Through all that time, the children never lost this mental advantage. The research team concluded that the IQ superiority resulted exclusively from DHA, a known component of breast milk. Most American baby formulas do not contain any DHA.
In psychology and physiology journals, articles routinely confirm the value of omega-3 fatty acids. One published study demonstrated that fish oil reduced the degree of brain damage in cats experiencing stroke. A study by researchers at the University of Pittsburgh showed that adults with low levels of omega-3 in their bodies were far more depressed, pessimistic, and impulsive than those with normal or high levels. This evidence improves the prospects for treating depressed patients effectively. Many therapists now say they are determined to coordinate psychological therapy with dietary therapy in order to rely less on drugs.
As research continues to show, new ways of thinking about fat can open the door to better physical, mental, and emotional health.
A. The key to health is to allocate a percentage of your fat intake to each type of fat.
B. There is evidence that DHA plays a big role in the intellectual performance of humans.
C. Food affect a person’s moods and motivation.
D. Most people associate the term fat with poor health.
E. Fats are broadly classified as either "saturated" or "unsaturated".
F. Keeping your fat intake too low, on the other hand, could also be dangerous.
G. Breast milk is a better source of DHA than infant formulas.

答案
F
解析
上文提到要保持健康,摄入的脂肪量就要低,下文提到脂肪中的脂肪酸对身体也有诸多益处,由此可知该句起到了转折的作用,即脂肪摄入过低也不行,故选F。
