The colourful chalkboards and baskets of fruit that greet customers at the entrances of Whole Foods Market's shops paint a rosy picture.Yet shares in the American seller of organic and natural food have fallen by more than 40%since hitting a peak last October,in a period when stock markets have been strong.
It is not that the retailer is in immediate crisis:its latest quarterly figures,on July 30th heowed sales and profits both up a bit.And it is not that people are going off the idea of paying more for food produced without chemical fertilisers,pesticides or additives:the International Federation of Organic Agriculture Movements reckons that the industry's worldwide revenues were a record of 63 billion in 2012;and Techsci Research,a market-research firm,predicts that the American market for such foods-the worlds largest-may grow by 14%by 2018.
The problem is that at Whole Foods,shoppers have been paying way over the cost of regular produce,and its success in getting them to do so has now attracted a lot of competitors,from rival organics chains like Sprouts and Trader Joe's to mass-market retailers like Walmart and Costco.As a result,the price premium for organic produce is crashing down.On a recent shopping trip,a pound of organic apples cost 2.99 at Whole Foods but just 1.99 at Sprouts and even less at Costco.
The firm has been trimming costs to keep its margins up,but the slump in its share price reflects investors expectation that this cannot continue,that profits will suffer and that Whole Foods'dominance of the market is coming to an end.
That the company has had to recall a number of products—in late July it and other grocers recalled plums and peaches suspected of contamination with Listeria bacteria—has made it harder to maintain an air of superiority over its competitors.Organic foods'claim to superiority is questionable anyway.Both Britain's Food Standards Agency and the Annals of Internal Medicine,a journal,concluded after reviewing the extensive studies on the issue that there is no substantial difference in the nutritiousness of organics and non-organics.In some respects organics may be bad for the environment,because growing them uses land less efficiently than non-organics.
As for“natural”foods,there is no official definition of this,inAmericaat least;so the label,which Whole Foods also applies to many products,is close to meaningless.Alan McHughen,a botanist at the University of California,Riverside,argues that the whole industry is 99%marketing and public perception,reeling people in through a fabricated conceptof a time when food,and life in general,was simple and wholesome.
If true,the trick has worked nicely for Whole Foods.But its success has attracted so many imitators that it is losing its uniqueness Even recent speculation about a takeover bid has failed to lift its shares.It may insist its food is sustainable But it seems its prices are not.下列哪一选项与划线部分所表达意思相同A.Crisis Seems Far
B.The Firm Is at Risk
C.More Rivals Join In
D.Natural Foods Are Unreal
E.Stop Buying Organic Foods
F.The Recall Makes Things Worse
G.Traditional Foods Face Challenge

The food we eat seems to have profound effects on our health.Although science has made enormous steps in making food more fit to eat ,it has, at the same time,made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well,especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additives,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes,but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has tried repeatedly to control these procedures, the practices continue.

问答题Passage 3Fermented Foods for Babies Malnutrition during weaning age-when breast milk is being replaced by semi-solid foods-is highly prevalent in children of poor households in many developing countries. While the etiology is complex and multifactorial, the immediate causes are recognized as feeding at less than adequate levels for children’s growth and development, and recurrent infections, including diarrhea, resulting mainly from ingestion of contaminated foods. As a result, many young children, particularly between six months to two years of age, experience weight loss and impaired growth and development. Studies by investigators in various countries have concentrated on traditional food preparation methods and have resulted in offering cheap and practical answers to these problems based on familiar, indigenous and culturally acceptable home processing practices. Two such answers have arisen. Firstly, cereal fermentation is used for reducing the risk of contamination under the existing inappropriate conditions for food preparation and storage in many households. Secondly, a tiny amount of sprouted grains flour is used in preparation of weaning foods as a magic way to lessen the viscosity without decreasing energy density. A method to eliminate pathogenic bacteria and inhibit their growth during storage of weaning preparations can benefit nutrition and health in young children considerably. Use of fermented foods for feeding children of weaning age appears to be an effective solution. Fermented foods have lower levels of diarrhoeal germ contamination, they are suitable for child feeding, and can be safely stored for much longer periods of time than fresh foods. The practice has been a traditional way of food preservation in many parts of the world. The anti-microbial properties of fermented foods and their relative higher safety-documented since the early 1900’s-have been indicated in a number of studies. In Ghana, it is common to ferment maize dough before cooking it as porridge. In Kenya, cereal-based porridge and milk are traditionally fermented. Preserving milk in the form of yoghurt has been known to many households living in hot climates. What are the underlying mechanisms by which fermentation processes help to prevent or reduce contamination? A possible answer suggests that during the fermentation process foods become more acid. This explains why diarrhoea-causing bacteria are not able to grow in fermented foods as rapidly as in unfermented ones. It is also hypothesized that some of the germs present in the foods are killed or inhibited from growing through the action of anti-microbial substances produced during fermentation (Dialogue on Diarrhoea, 1990). The fermented foods can, therefore, be kept for a longer time compared to fresh ones. It has been shown that while contamination levels in cooked unfermented foods increase with storage time, fermented foods remain less contaminated. Whatever the underlying mechanisms, the fact is that the exercise reduces contamination without adding to the household cost both in terms of time and money. Its preparation is easy. The cereal flour is mixed with water to form a dough which is left to be fermented; addition of yeast, or mixing with a small portion of previously fermented dough is sometimes needed. The dough can then be cooked into porridge for feeding to the child. Although beneficial, unfortunately the practice is going out of fashion, partly because of current emphasis on the use of fresh foods, particularly for children. For example, a study on the use of fermented foods for young children in Kenya (Dialogue on Diarrhoea, 1990), demonstrated that while foods are still frequently fermented at home for child feeding, their use is becoming less popular, particularly in urban areas where commercial products are more available. Clearly they now need to be promoted. Complete the summary with the list of words A-N below. Write your answers in boxes 1-7 on your answer sheet. Malnutrition and the resulting impaired growth and development in children of weaning age in developing countries result not only from 1______ but also from infections caused by 2______. Studies have addressed the problem of inadequate intake by using sprouted grains in food preparation. Contamination has been tackled with 3______. Both of these methods are, or were, used traditionally and are practical and inexpensive. Fermented foods have higher 4______ and also have anti-microbial qualities. This means that contamination is decreased and that their 5______ is increased. Fermentation occurs when 6______ is left to stand, occasionally with simple additives. There is, however, a trend away from this 7______ to commercial products.A. porridge H. storage lifeB. malnutrition I. sprouted grainsC. fermentation J. inadequate food intakeD. new technology K. acidityE. contaminated food L. unfermented foodF. diarrhoeal germs M. weaningG. traditional food N. dough

问答题Practice 1 Are organically grown foods the best food choices? The advantages claimed for such foods over conventionally grown and marketed food products are now being debated. Advocates of organic foods—a term whose meaning varies greatly—frequently proclaim that such products are safer and more nutritious than others. The growing interest of consumers in the safety and nutritional quality of the typical North American diet is a welcome development. However, much of this interest has been sparked by sweeping claims that the food supply is unsafe or inadequate in meeting nutritional needs. Although most of these claims are not supported by scientific evidence, the preponderance of written material advancing such claims makes it difficult for the general public to separate fact from fiction. As a result, claims that eating a diet consisting entirely of organically grown foods prevents or cures disease or provides other benefits to health have become widely publicized and form the basis for folklore.
