Fruit and vegetables are good sources of dietary fibre, but we should reconsider the importance of fungi and seaweed as dietary fiber supplying food.Physicochemical properties of and dietary fiber content in Auricularia auricula, Auricularia polytricha, Tremella fuciformis, Grifola albicans, kelp, sea mustard, Hizikia fusiformis, Gelidium amansii, and agar-agar were measured. They have relatively high water holding capacity, settling volume in water, bulk density, anti-oxidative and reducing activities, high dietary fiber content and relatively high ammonium oxalate-oxalic acid soluble substance (OOSS). Feeding fungi did not accelerate the gastrointestinal transit time, however faecal water content was increased by fungi feeding. The increase may be attributed to the OOSS.Although OOSS is not effective in the gastrointestinal transit time as cellulose is, OOSS may have an effect on constipation prevention by the increased water content in the faeces. Therefore fungi and seaweed can wor … More k efficiently as dietary supplying food and can show physiological effects.Although Japanese panellists preferred both Auricularia auricula and Auricularia polytricha, Korean panellists preferred Auricularia auricula to Auricularia polytricha. Korean people are familiar to Auricularia auricula but Japanese people are familiar to Auricularia polytricha. Almost all college students in Japan and in Korea know the word-dietary fibre, but they do not always eat fungi and seaweed to prevent constipation.All the students in elementary school do not think that constipation has bad effects on their health. However, the elder the students were, the bigger the number of the students who knew dietary fiber became. All of them did not understand the physiological importance of dietary fibre. Considerable number of the students did not expect fungi and seaweed to be rich in dietary fibre.It is needed to reconsider the importance of fungi and seaweed as dietary fiber supplying food and to let students know the physiological importance of dietary fibre.

测定了黑木耳、毛木耳、银耳、白灰树花、海带、芥菜、羊栖菜、石花菜和琼脂的理化性质和膳食纤维含量。它们具有较高的持水力、水中沉降量、容重、抗氧化和还原活性、较高的膳食纤维含量和较高的草酸-草酸铵可溶性物质（OOSS）。饲喂真菌并没有加快胃肠通过时间，但粪便含水量增加真菌喂养。这种增加可能归因于OOSS。尽管OOSS在胃肠通过时间方面不如纤维素有效，但OOSS可能通过增加粪便中的含水量而对便秘预防产生影响。因此真菌和海藻可以 ...更多信息 虽然日本的小组成员喜欢黑木耳和毛木耳，但韩国的小组成员更喜欢黑木耳而不是毛木耳。韩国人熟悉木耳，日本人熟悉毛木耳。在日本和韩国，几乎所有的大学生都知道膳食纤维这个词，但他们并不总是吃真菌和海藻来防止便秘。所有的小学生都不认为便秘对他们的健康有不良影响。但年龄越大，知道膳食纤维的学生越多。他们都不了解膳食纤维的生理重要性。有相当一部分学生认为菌类及海藻不含丰富的膳食纤维，应重新认识菌类及海藻作为膳食纤维供应食物的重要性，让学生认识膳食纤维的生理重要性。少
