The objective of this study was to assess the efficacy of two current cynosure protein substitutes; quinoa and amaranth in controlling short term food intake and satiety in rats. Experimental rats were allotted to three groups (n-- per group) and fed with diets containing casein, quinoa and amaranth as major protein sources, with casein diet kept as control. At the end of the experiment it was observed that the rats ingesting quinoa and amaranth supplemented diets exhibited lesser food intake (p-lt;-.01) and lesser body weight gain significantly in amaranth (p-lt;-.05) as compared to control. They seemed to bring down plasma ghrelin levels while meliorating plasma leptin and cholecystokinin (CCK) levels postprandially (p-lt;-.01). Although both quinoa diet and amaranth diet were effective in improving blood glucose response and maintaining plasma free fatty acids (FFA) and general lipid profiles subsequently after the meal, amaranth diet showed significant effects when compared to control and amaranth diets. There was 15 % improvement in blood glucose profile in the amaranth group with respect to the control at 90 min, where as there was only 3.4 % improvement in the quinoa group. These findings provide a scientific rationale to consider incorporation of these modest cereals in a diet meant to fight against growing obesity and poverty.
