title: Effects of sago starch content in the diet on lipid peroxidation and antioxidative enzyme activities in rats.
abstract: The effects of sago starch content in diets on the status of lipid peroxidation and antioxidative enzyme activities were examined with rats fed cholesterol-free and cholesterol-enriched diets. Despite the diets with and without supplemental cholesterol, both food intake and the value of plasma thiobarbituric acid reactive substances (TBARS) showed a lower tendency or lower values in the rats fed the diet with a high ratio of sago starch as compared to a low ratio. Liver superoxide dismutase (SOD) and catalase activities, and serum and liver alpha-tocopherol concentrations were higher in the rats fed the cholesterol-free and enriched diets with a high ratio of sago starch as compared to a low ratio. From these results, it was suggested that a higher ratio of sago starch in the diet may be useful to keep the in vivo oxidative status at a lower level.
