In Chinese Herbal Medicine, it is clearly stated that the tubers of dioscorea alata possess the function of nourishing, strengthening the stomach and the body, and ceasing diarrhea and thirst. It is also widely spread in the temperate zones and the tropics. The real function of dioscorea alata is still under dispute. Yet some reports point out that dioscorea alata is regarded as an anti-oxidant, or is used to increase the hormone combination and remove the bacterias. Nowadays in Taiwan, although some people have already made good use of dioscorea alata, the real comprehension of how it works is incomplete and thus makes the confirmation of the saying in Chinese Herbal Medicine, so far, impossible. For instance, the Japanese would mainly eat the dioscorea alata uncooked; while the Taiwanese cooked. As for the function of dioscorea alata, we still have quite a lot to explore, though lots of reports from other countries indicate that cooked dioscorea alata is not as good as uncooked one, for cooked dioscorea alata would lose certain untrition. Yet in Japan or Taiwan, as we mentioned earlier, people still hold their points of view. Which one is right? We have to verify. This study will focus on how the cooked dioscorea alata and uncooked dioscorea alata would be affected and changed physically and metabolically.山藥(學名Dioscorea alata或稱Wild Yam)原名為薯蕷科(Dioscoreaceae),薯蕷屬的蔓性植物(Climbing Plant),是自古以來就廣被當成食物之一的藥用植物,於本草綱目(Chinese herbal medicine)內即有記載,其塊莖(tuber)具有滋養、健胃、強身、止瀉及止渴之功能,也廣泛分布於溫、熱帶之區域.在於其真正的功能上則尚有許多仍存在令人爭議之處,但亦有報告指出山藥具有抗氧化或增加hormone的合成及除菌等作用.目前台灣地區對於山藥的吃法及用途上,雖有民間上一些用法及功能,呈現出模糊的意識形態,事實上以專一劑型的使用仍存一知半解的情況下,仍無法證實於本草綱目上之功能效用.就如同以日本的食用方式以生食為主,但在台灣則無法充分利用生食,主要仍以熟食的飲食習慣為多,因此對於山藥的利用度來看,仍存在很大的研究空間,雖已有許多國外的報告指出,熟食的效果比生食差,因是有某些成份會因煮熟之後就喪失其功能,但在日本及台灣一般仍堅持生食與熟食其效果上是相同的,是否真的如此,則有待更進一步的確認.本研究仍想證實生食與熟食之間是否會對生理上及代謝上的改變作一證實性的探討.Project
