Fruit and Vegetable Juices as Beneficial to Health as Fruits and Veggies¹

    A European study has revealed that 100 percent fruit and vegetable juices are as effective as their whole fruit/vegetable counterparts in reducing risk factors related to certain diseases. The conclusion is the result of the study designed to question traditional thinking that 100 percent juices play a less significant role in reducing risk for both cancer and cardiovascular disease than whole fruits and vegetables.

    Juices are comparable in their ability to reduce risk compared to² their whole fruit/ vegetable counterparts, according to several researchers in the United Kingdomwho conducted the literature review. The researchers analyzed a variety of studies that looked at risk reduction attributed to³ the effects of both fiber and antioxidants. As a result, they determined that the positive impact fruits and vegetables offer come not from just the fiber but also from antioxidants which are present in both juice and the whole fruits and vegetables.⁴

    “When considering cancer and coronary heart diseases⁵ prevention, there is no evidence that pure fruit and vegetable juice sare less beneficial than whole fruit and vegetables,” the researchers said. The researchers added that the positioning of juices as being nutritionally inferior to⁶ whole fruits and vegetables in relationship to chronic disease development is “unjustified” and that policies, which suggest otherwise about fruit and vegetable juices, should be re-examined.

    The researchers who authored the paper suggest that more studies in certain area are needed to bolster their findings. “Although this independent review of the literature is not designed to focus on any particular 100 percent juice, it does go a long way⁷ in demonstrating that fruit and vegetable juices do play an important role in reducing the risk of various diseases, especially cancer and cardiovascular disease," said Sue Taylor. Her opinion is in agreement withs⁸ the Juice Products Association⁹ , a non-profit organization not associated with this research. She added that appropriate amounts of juices should be included in the diet of both children and adults, following guidelines established by leading health authorities.Tayloralso points to a large epidemiological study, published in the September 2006 issue of the Journal of Medicine, which found that consumption of a variety of 100 percent fruit and vegetable juices was associated with a reduced risk for Alzheimer’s disease¹⁰.

    In fact, that study found that individuals who drank three or more servings of fruit and vegetable juices per week had a 76 percent lower risk of developing Alzheimer’s disease than those who drank juice less than once per week. The study was published in the International Journal of Food Science and Nutrition TM¹¹ (2006).

The judgment that fruit and vegetable juices are lels beneficial to reducing chronic disease development is______.

A:evident B:obvious C:incorrect D:conclusive

Every second in the United States alone, more than 250 animals are slaughtered for food, adding up to more than 8 billion animals each year. Reducing the amount of meat in one’s diet is nutritionally, environmentally, and ethically beneficial.
People who eat meat usually have weaker immune systems compared to those of vegetarians. Meat has been directly linked to diabetes, obesity, arthritis, and many other illnesses. Furthermore, meat-eaters are at a higher risk for diseases, including cancer, and they are more likely to die from these diseases. Critics say that a meatless diet does not provide enough nutrients, especially protein and iron. Actually, according to A Teen’s Guide to Going Vegetarian, by Judy Krizmanic, protein is found in almost every food, and iron appears in many vegetables. Getting enough nutrients in a meat-reduced diet should not be difficult. A 1988 study found that some of the highest pesticide residues appear in meat and eggs. Diets including more fruits and vegetables will only make people healthier.
Some skeptics believe that there will be a shortage of food if animals are not eaten. In fact, the opposite is true. More than 80% of the corn and 95% of the oats grown in the US are fed to livestock. The world’s cattle alone consume enough food to equal the caloric needs of 8.7 billion people, more than the entire human population. One half of the water used in the Unites States also goes to livestock; 2.50 gallons of water produces only 1 pound of beef. If people eat less meat and more plants, the amount of available food will increase.
Many people become vegetarians because they feel that eating animals is unethical. 90% of these animals are raised in confinement. Chickens and other birds have only about half. a square foot of space each, and since they are raised so close together, a hot blade is used to cut off their beaks to prevent them from pecking each other to death. Likewise, pigs that are repressed will bite each other’s tails, so both their teeth and tails are removed as soon as they are born.
Eating animals is hazardous in numerous ways. Even a slight reduction in meat intake is better than nothing at all. Consuming less meat is beneficial to the health of animals, the health of people, and to the health of the world.
In the third paragraph, the author implies that

A:food will be insufficient if animals are not eaten. B:lots of food and water are consumed by cattle. C:a meat-reduced diet is environmentally beneficial. D:animals are raised for human food.

Text 1
Say the word bacteria, and most folks conjure up images of a nasty germ like staphylococcus or salmonella that can make you really sick. But most bacteria aren’t bad for you. In fact, consuming extra amounts of some bacteria can actually promote good health. These beneficial bacteria are available without a prescription in drug and health-food stores and in foods like yogurt. So far, the best results have been seen in the treatment of diarrhea, particularly in children. But re searchers are also looking into the possibility that beneficial bacteria may thwart vaginal infections in women, prevent some food allergies in children and lessen symptoms of Crohn’s disease, a relatively rare but painful gastrointestinal disorder.
So where have these good germs been lurking all your life In your intestines, especially the lower section called the colon, which harbors at least 400 species of bacteria. Which ones you have depends largely on your environment and diet. An abundance of good bacteria in the colon generally crowds out stray bad bacteria in your food. But if the bad outnumber the good—for example, after antibiotic treatment for a sinus or an ear infection, which kills normal intestinal germs as well—the result can be diarrhea.
For generations, people have restored the balance by eating yogurt, buttermilk or other products made from fermented milk. But nowadays, you can also down a few pills that contain freeze-dried germs. These preparations are called probiotics to distinguish them from antibiotics. Unfortunately, you can’t always be sure that the bacteria in the products you buy are the same strains as those listed on the label or even that they’re still alive. Probiotics are usually sensitive to both heat and moisture. Among the most promising and most thoroughly researched probiotics is the GG strain of Laetobacillus, discovered by Dr. Sherwood Gorbach and biochemist Barry Goldin, both at Tufts University School of Medicine. L-GG, as it’s called, has been used to treat traveler’s diarrhea and intestinal upsets caused by antibiotics. Even more intriguing, L- GG also seems to work against some viruses, including rotavirus, one of the most common causes of diarrhea in children in the U. S. and around the world. Here the effect is indirect. Somehow L-GG jump-starts the immune system into recognizing the threat posed by the virus.
Pediatricians at Johns Hopkins are studying a different bug, the Bb-12 strain of Bifidobacterium, which was discovered by researchers at CHR Hansen Biosystems. Like L-GG, Bb-12 stimulates the immune system. For reasons that are not dear, infants who are breast-fed have large amounts of bifidobacteria in their intestines. They also have fewer intestinal upsets. Dr. Jose Saavedra and colleagues at Hopkins have shown that Bb-12 prevents several types of diarrhea, including that caused by r0tavirus, in hospitalized infants as young as four months. It has also been used to cure diarrhea in children of all ages.

What the author mainly intends to say in the first paragraph is （）

A:that nasty germs can make you really sick B:that the word bacteria doesn't refer to the germs which make people sick C:the beneficial effects that most bacteria may produce on human body D:the possibility that beneficial bacteria may stop vaginal infections in women

Humans are peculiar as a species, so what makes them so must be hidden in their genome. To an almost disconcerting extent, though, the human genome looks similar to the genomes of other primates, especially when it comes to the particular proteins it allows cells to make. The powerful new ways of looking at the genome being pioneered by the ENCODE consortium, though, provide ways to seek out the subtle species—specific signals. Lucas Ward and Manolis Kellis of the Massachusetts Institute of Technology report on the results of such sleuthing in a paper just published in Science.
The two researchers used data from ENCODE to identify the bits of the genome that actually do things and data from the 1,000 Genomes Project, which has studied human-genome variation across hundreds of people, to discover how much these functional elements vary from person to person. In particular, they looked for telltales that an element is being maintained by natural selection. If something is evolutionarily important then random variations in its DNA sequence will be slowly eliminated from the population, keeping it on the functional straight and narrow in a process known as purifying selection.
Dr Ward and Dr Kellis found that, in addition to the 5 % of human DNA that is conserved between mammals, an additional 4 % of human DNA appears to be uniquely human in the sense that it is prone to purifying selection in humans but not in other mammals. Much of this proprietary DNA is involved in regulating gene activity—for example, controlling how much of a protein is produced, rather than changing the nature of the protein itself. This finding is in line with modern thinking that a lot of evolutionary change is connected with regulatory elements rather than actual protein structure. The researchers also found that long non-coding segments that are not conserved in other mammals are in fact highly constrained in humans, suggesting they have human-specific functions.
Some areas identified as particularly human are the regulation of the cone cells of the retina (which are involved in colour vision) and the regulation of nerve-cell growth. These processes evolved rapidly in man’s primate ancestors but are now under strong purifying selection to maintain their beneficial functions. The implications of that, given humanity’s main distinguishing feature—its huge brain—are obvious. Dr Ward and Dr Kellis have thus created a powerful tool for investigating in detail just what it is that makes a human being human.
The word "prone" (Line 2, Paragraph 3) most probably denotes ______.

A:reluctant B:apt C:beneficial D:limit

Passage Four Exercise, everyone advises! But immediately, when you try, you run into trouble. There is so much contradictory, sometimes incorrect advice about exercising that you become confused. Test yourself on the following true false quiz. It will tell you what you need to know. 1. To lose weight you should always "work up a good sweat" when exercising. False. Sweating only lowers body temperature to prevent overheating; it does not help you reduce weight. You may weigh less immediately after a workout, but this is due to water loss. Once you replace the liquid, you replace the weight. 2. You burn more calories jogging one mile than walking the same distance. False. You use the same amount of energy whether you walk or jog the mile, since in both cases you are moving the same weight the same distance. The speed doesn’t matter. Of course, if you jog rather than walk for 30 minutes, you’ll cover more distance, and therefore burn more calories. 3. If your breathing doesn’t return to normal within minutes after you finish exercising, you’ ve exercised too much. True. Five minutes or so after exercising, your breathing should be normal, your heart shouldn’t be pounding, and you shouldn’t be exhausted. Beneficial exercise is not too difficult, unpleasant, and exhausting; it is enjoyable and refreshing. 4. Walking is one of the best exercises. True.. Walking helps circulation of blood throughout the body, and thus has a direct effect on your overall feeling of health.

Quiz 3 shows the author's opinion by（）

A:telling readers to exercise for five minutes a day B:pointing out wrong ways in exercising C:giving examples of beneficial exercise D:comparing the results of beneficial exercise and too much exercise
