The famous British nutritionist Cum-mings et al. demonstrated that the intake of non-starch polysaccharides should not exceed 32 g per day and that there is a dose-response relationship between the intake and the weight of the stool. The risk of diseases associated with a daily stool weight below 150g is increased. Based on these facts, the UK Department of Health recommends a dietary intake of 18g/day of non-starch polysaccharides for healthy individuals, a value similar to the 10g/1000kcal (1kcal = 4.18kJ) recommended by the Office of Life Sciences Research expert group. This is also the physiological indicator of stool weight as a predictor of appropriate fiber intake. The British National Advisory Council recommends a dietary fiber intake of 25g-30g/day (Na-tionalAdvisoryCommittec), and the average intake of dietary fiber in the United States is 12g/day, citing Lanzaetal, 1987, in the 10th edition of the RDA. 1986, the Life Sciences Research Division (LSRO) and the The American Society for Experimental Biology (ASEB) provided some reports in which the recommended amount of dietary fiber for healthy adults in the United States was proposed by the Expert Committee on Dietary Fiber to be 20-35 g per person per day of dietary intake, or 10-13 g per person per kilocalorie (4.2 MJ) of energy (equivalent to 20-35 g per day). The low limit of this recommended amount is the amount of fiber that can be maintained to play a role in intestinal function, and the upper limit is the amount that does not cause harmful effects due to excessive fiber intake. The intake of total dietary fiber recommended by the US FDA is 20-35g per day (adults) (PilchSM et al.) Williams proposed that the dietary fiber intake for children in the United States is 5g/day and 10g/day based on age plus 5g/day since the age of 2 years or older, which is based on maintaining laxity and contributing to the prevention of certain chronic diseases in the future, i.e. 5g (children 2 years), 8g (children 3 years or older), and 25g- 25g/day. ), and 25g-30g (adults over 20 years of age). An average daily intake of 25g of dietary fiber for Australians significantly reduced the incidence of coronary heart disease and mortality. A Canadian survey results for a daily dietary fiber intake of 22-24g/day per person. Our National Nutrition Institute proposed in 2000: the appropriate intake of dietary fiber for adults is 30.2g/day. 30.2g/day of total dietary fiber can be provided from 400g of cereals, 450g of vegetables, 150g of fruits, and 50g of soy products. If you choose your food carefully, it is not difficult to get 30.2g of fiber a day. Because our diet such as rice, wheat flour, corn, fruits and vegetables contain more fiber. However, care should be taken to gradually increase the amount of fiber intake to avoid excessive exhaustion caused by excessive consumption at one time.
