Abstract

Last years, the concept of resistant starch (RS) has evoked a new interest in researchersin the context of bioavailability of starch and its use as a source of dietary fiber. Based on clinicaland animal research, RS has been proposed to be the most potentially beneficial starch fraction forhuman health. In this study, the effects of amylose starch as a fraction of RS on development andlifespan of fruit fly Drosophila melanogaster were investigated. In both Canton S and w1118 strains, thediet with 20% amylose RS delayed fly development, increased triacylglyceride level in the body ofadult insects and reduced their lifespan compared to the diet with 4% amylose starch. Thus, ourdata clearly demonstrate that amylose starch at high concentrations may negatively affect fruit fly
