The Effect of Resistant Starch on Physic-Nutrition Availability in Human

In order to observe the effects of resistant starches on the physio-nutrition in women, nine female university students were investigated using cellulose (CED), resistant starch 3 (RS3D) and resistant starch 4 (RS4D) diets. Each woman's daily intake and excretions of energy, protein and lipid were mesured together with the apparent digestibility and the amounts of total cholesterol and HDL-cholesterol were measured. The results obtained from this researh are as follows. The daily energy intake were significantly higher in the RS4D (Resistant starch 4 diet) compared with the CED(Cellulose) and the RS3D (Resistant starch 3 diet). The metabolic energy in those periods with RS added to their diets were significantly higher whereas the metabolic energy in the period CED was significantly low. The daily protein intake was significantly higher in the RS4D compared with the CED and the RS3D. The apparent digestibility of protein was significantly higher in the RS4D compared with the CED and the RS3D. The daily lipid intake was significantly higher in the CED compared with the RS3D and the RS4D. The apparent digestibility of lipid was not significant in that period. The concentration of total cholesterol, HDL-cholesterol, % of HDL-cholesterol and atherogenic index (A.I.) were not significant in those period. As the above results indicate, while RS3 appear to have similar effect on energy consumption rate, apparent protein digestibility and content of cholesterol in plasma, compared with the CED, but energy consumption rate and apparent digestibility of protein are significantly higher in the RS4D compared with the CED. Thus, it appears that cellulose and RS 3 share similar effects on physio-nutrition in human, while RS4 does not have the similar effects. (Korean J Nutrition 35(9) : 932∼942, 2002)
