　　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 animalmodel, researchers in Spain found that pigs fed large 51 of raw potato starch (RPS) not onlyhad a healthier bowel, but also decreased levels of white blood cells,52 as leucocytes andlymphocytes in their blood. White blood cells are produced as a 53 of inflammation or disease,generally when the body is challenged.

　　The general down-regulation of leucocytes observed by the Spanish researchers suggests anoverall beneficial effect, a generally more 54 body. The reduction in leukocyte levels wasabout 15 percent. Lower lymphocyte levels are also indicative of 55 levels of inflammation,but the observed reduction in both lymphocyte density 56 lymphocyte apoptosis issurprising.

　　In 57was the longest study of its kind, pigs were fed RPS over 14 weeks to 58theeffect of starch on bowel health. "The use of raw potato starch in this experiment is 59 to simulatethe effects of a diet high in resistant starch," said study leader Jose Francisco Perez at theUniversitat Autonoma de Barcelona, Spain.

　　Humans do not eat 60 potatoes, but they do eat a lot of foods that contain resistantstarch, such as cold boiled potatoes, legumes, grains, green bananas, pasta and cereals. About 10percent of the starch eaten by human is resistant starch--starch that is not 61 in the smallintestine and so is shunted into the large intestine where it ferments. Starch consumption isthought to reduce the 62 of large bowel cancer and may also have an effect on irritablebowel syndrome (IBS).

　　Immunology expert Lena Oman's team 63 found that the overall lymphocyte levels donot vary for IBS patients, but that lymphocytes are transferred from the peripheral blood to the gut,which support the hypothesis of IBS being 64 least partially all inflammatory disorder. Shesays the decrease in lymphocytes observed by the Spanish is therefore interesting, and a diet ofresistant starch may be worth 65 in IBS patients. Oman is currently at the Department ofInternal Medicine, Goteborg University, Sweden. The study is published in the Journal ofChemistry and Industry, the magazine of the SCI.
