2015职称英语考试真题及答案：卫生类B级完形填空

　　In what was the longest study of its kind, pigs were fed RPS over 14 weeks to find out the effect of starch on bowel health. The use of raw potato starch in this experiment is designed to simulate the effects of a diet high in resistant starch, said study leader Jose Francisco Perez at the Universitat Autonoma de Barcelona3, Spain.

　　Humans do not eat raw potatoes, but they do eat a lot of foods that contain resistant starch, such as cold boiled potatoes, legumes, grains, green bananas, pasta and cereals. About 10 percent of the starch eaten by human is resistant starch - starch that is not digested in the small intestine and so is shunted into the large intestine where it ferments. Starch consumption is thought to reduce the risk of large bowel cancer and may also have an effect on irritable bowel syndrome (IBS)4.

　　Immunology expert Lena Omans team previously found that the overall lymphocyte levels do not vary for IBS patients, but that lymphocytes are transferred from the peripheral blood to the gut, which support the hypothesis of IBS being at least partially all inflammatory disorder. She says the decrease in lymphocytes observed by the Spanish is therefore interesting, and a diet of resistant starch may be worth trying in IBS patients. Oman is currently at the Department of Internal Medicine, Goteborg University, Sweden5. The study is published in the Journal Chemistry and Industry, the magazine of the SCI6.
