　　Eating Potatoes Gives Your Immune System a Boost

　　Eating potatoes is not only good for bowel health，but also for the whole immune system， especially 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 quantities of raw potato starch (RPS)1 not only had a healthier bowel, but also decreased levels of white blood cells, such as leucocytes and lymphocytes in their blood. White blood cells are produced as a result of inflammation 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 healthy body.2 The reduction in leucocyte levels was about 15 percent. Lower lymphocyte levels are also indicative of reduced levels of inflammation ’ but the observed reduction in both lymphocyte density and lymphocyte apoptosis is surprising.

　　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 一 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 Ohman's 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 an 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. Ohman 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.

　　答案與題解：

　　1.C短文開(kāi)頭第一句就說(shuō),“吃土豆有益于腸道健康，而且對(duì)整個(gè)免疫系統(tǒng)也有益,尤其是吃 土豆色拉或涼吃”，因此在四個(gè)選項(xiàng)中最有營(yíng)養(yǎng)的非C項(xiàng)莫屬。

　　2.A第二段第三句說(shuō)，“淋巴細(xì)胞水平低顯示炎癥水平下降”，故其他B、C、D三個(gè)選項(xiàng)均不正確。

　　3.B ^二段第二句引用了研究組負(fù)責(zé)人自己的話說(shuō)，“在實(shí)驗(yàn)中使用未經(jīng)加工的土豆淀粉，就 是為了模擬富含耐久淀粉的飲食所起的作用”，其他A、C、D三個(gè)選項(xiàng)文章均沒(méi)有提及。

　　4. D第四段第一句列出了一些富含耐久淀粉的食品，其中就沒(méi)有D項(xiàng)“蔬菜”，而且實(shí)際上蔬 菜也不是富含淀粉的食物。

　　5. D第四段倒數(shù)第二句已經(jīng)解釋了耐久淀粉的特點(diǎn)：“不能在小腸中消化，而是分流到大腸， 在大腸中發(fā)酵?！逼渌x項(xiàng)個(gè)別詞語(yǔ)雖在短文中出現(xiàn)過(guò)，但都不是說(shuō)明耐久淀粉的。

　　譯文：食用土豆有益我們的免疫系統(tǒng)

　　吃土豆有益于腸道健康，而且對(duì)整個(gè)免疫系統(tǒng)也有益，尤其是吃土豆色拉和涼吃。在對(duì)動(dòng)物模式的一個(gè)研究中，西班牙的調(diào)查者發(fā)現(xiàn)用未經(jīng)加工的土豆淀粉喂養(yǎng)的豬不僅腸道更健康，而且白血 細(xì)胞的水平降低了，如血液中的白細(xì)胞和淋巴細(xì)胞的數(shù)量。白血細(xì)胞通常是身體受到考驗(yàn)而產(chǎn)生炎 癥和疾病時(shí)產(chǎn)生的。

　　西班牙研究者們所觀察到的白血球水平的整體下調(diào)意味著未經(jīng)加工的土豆淀粉具有全面的有 益的作用，也就是總的來(lái)說(shuō)身體是更加健康。白血球數(shù)量降低了大約百分之十五。淋巴細(xì)胞數(shù)量的 降低顯示炎癥指標(biāo)的下降，然而觀察到的淋巴細(xì)胞濃度和淋巴細(xì)胞凋亡的減少卻是驚人的。

　　在對(duì)此進(jìn)行的最長(zhǎng)的研究是用未經(jīng)加工的土豆淀粉喂養(yǎng)豬14個(gè)星期后來(lái)判定淀粉對(duì)腸道健康 的影響?！霸趯?shí)驗(yàn)中使用未經(jīng)加工的土豆淀粉,就是為了模擬富含耐久淀粉的飲食所起的作用?！蔽?班牙巴塞羅那自治大學(xué)的研究負(fù)責(zé)人Jose Francisco Perez這樣說(shuō)道。

　　人們不吃未經(jīng)加工的土豆，但是卻吃很多富含耐久淀粉的食物，比如說(shuō)涼的熟土豆、豆莢、糧食、 綠香蕉、面食、谷物等。人們食用的淀粉大約有百分之十為耐久淀粉，也就是不能?小腸中消化，而 是分流到大腸，在大腸中發(fā)酵的淀粉。食用淀粉被認(rèn)為可以降低大腸癌的得病幾率，還有可能對(duì)過(guò) 敏性腸綜合征起作用。

　　免疫學(xué)老師Lena Ohman的研究小組曾發(fā)現(xiàn)過(guò)敏性腸綜合征病人的淋巴細(xì)胞數(shù)量并沒(méi)有改變， 然而淋巴細(xì)胞卻是從周?chē)难恨D(zhuǎn)移到腸內(nèi)，這就給過(guò)敏性腸綜合征至少部分是炎癥性疾病的假設(shè) 提供了依據(jù)。Lena Ohman說(shuō)道，因?yàn)槿绱?西班牙人觀察到的淋巴細(xì)胞的減少很有趣，耐久淀粉食 品也許值得在過(guò)敏性腸綜合征病人身上試驗(yàn)。Ohman近來(lái)在瑞典哥德堡大學(xué)內(nèi)科醫(yī)學(xué)系工作，她 的研究成果發(fā)表在科學(xué)引文索引數(shù)據(jù)庫(kù)收錄的期刊《化學(xué)和工業(yè)》上。
