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 , atthe same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of cancer is related to the diet as well, especially cancer the colon . Different cultures are more prone to contract certain illnesses because of the food that is characteristic in these cultures. That food related to llness is not a new discovery. In 1945 , government researchers realized that itrates and nitrites, commonly used to preserve color in meats, and other food dditives, caused cancer. Yet, these carcinogenic additives remain in our food, nd it becomes more difficult all the time to know which things on the pack ging 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 poultry, and because of this, penicillin has been found in the milk of treated cows. Sometimes similar drugs are administered to animals not for medicinal 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 controlthese procedures, the practices continue.

In the past, operations were difficult. Until the middle of the eighteen fifties, surgery was very dangerous. Many patients died after even the smallest operations. This was because bacteria entered the cuts in the patients bodied’and started infection. In some countries, up to 90 percent of patients died from inf ection after operations. In 1865, however, Joseph Lister, a British surgeon, found an answer to the problem. He used an “antiseptic during” and after operations. This killed the dangerous bacteria and most of his patients lived. Since then, surgeons have used antiseptics in all operations.Surgery has developed in many important ways since the day of Joseph Lister. Today, when patients go to hospital for an operation, they can expect thebest treatment, in clean and hygienic conditions.

Dear Sir/Madam,

I am pleased to write a letter of recommendation on behalf of Sand River and its CEO, Mrs. Jane King. I am very familiar with the company. My next book deals with it in detail, which is to be published in autumn of 2018. I am also familiar with European consumer. As a Dutch citizen, I have lived in Europe for 46 years and studied European consumer behavior for decades.I believe that Sand River offers something unique to the European market. It has established long-term supply relations with herdsman ( 牧民) families and owns advanced German machinery. Thus it combines natural resources with modern manufacturing techniques. But equally important, Sand River works with modern fashion designers to create truly contemporary and appealing designs. The result is a newly-established cashmere ( 羊绒) brand that appeals to a target group of high-income women. I met Mrs. King the first time in 2013. Since then, we have met several times and talked about Sand River's philosophy, strategy, and appeal to both Chinese and international consumers. I was struck by her deep knowledge about knitting (针织) technology, her enthusiasm for the brand, and her deep understanding of the cashmere shopper. I regard her as a "woman of her word." To summarize, I believe Sand River products deserve a place in luxurious European department stores and Mrs. King is a reliable partner. If you have any questions, please do not hesitate to contact me. Sincerely, Joan Smith
