Eating Potatoes Gives Your Immune System a Boost
Eating potatoes is not only good for bowel health,but also for the whole immune system,espe- cially when they come in the form of a potato salad or eaten cold.In a study on an animal model, researchers in Spain found that pigs fed large_________(51)of raw potato starch(RPS)not on-ly had a healthier bowel,but also decreased levels of white blood cells,________(52)as leuco- cytes and lymphocytes in their blood.White blood cells are produced as a_________(53)of in-fEammation or disease,generally when the body is challenged.
The general down-regulation of leucocytes observed by the Spanish researchers suggests an overall beneficial effect,a generally more_________(54)body.The reduction in leucocyte levels was about 15 percent.Lower lymphocyte levels are also indicative of_________(55)levels of in-flammation,but the observed reduction in both lymphocyte density_________(56)lymphocyte apoptosis is surprising.
In_________(57)was the longest study of its kind,pigs were fed RPS over 14 weeks to _________(58)the effect of starch on bowel health.“The use of raw potato starch in this experi-ment is_________(59)to simulate the effects of a diet high in resistant starch,”said study leader Jose Francisco Perez at the Universitat Autonoma de Barcelona,Spain.
Humans do not eat_________(60)potatoes,but they do eat a lot of foods that contain resist-ant 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_________(61)in the small intestine and so is shunted into the large intestine where it ferments.Starch consumption is thought to reduce the_________(62)of large bowel cancer and may also have an effect on irritable bowel syndrome(IBS).
Immunology expert Lena Ohman' s team_________(63)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 lBS being_________(64)least partially an inflammato- ry disorder. She says the decrease in lymphocytes observed by the Spanish is therefore interest-ing,and a diet of resistant starch may be worth_________(65)in lBS patients.Ohman is cur-rently at the Department of Internal Medicine,Goteborg University,Sweden.The study is pub-lished in the Journal Chemistry and Industry,the magazine of the SCI. 65._________

what引导从句作介词in的从句，且what在宾语从句中作主语，符合题意。
句意：用未经加工的土豆淀粉喂养猪14周以找出淀粉对肠道健康的影响。find out 意为“找出，发现”，符合题意。respond to对……做出反应；result in导致，引起；turn out 制造，结果是。
句意：在试验中喂猪吃未经加工的土豆淀粉，就是为了模拟富含抗性淀粉（resistant starch）的饮食所起的作用”,be designed to意为“目的是”，符合题意。analyzed分析； ensure确定；beginning开端，开始。
此处表示“人们不吃生土豆”,raw potatoes与raw potato starch(RPS）相呼应，意为 “未经加工的土豆”，即生土豆，故选D。
