摘要：Solanum torvum (STO) and edible insects are potential dietary approaches to prevent malnutrition. Hence, we determined the effect of STO and insect powders on improving nutritional status in malnourished rats. Malnutrition was induced in rats by feeding 5% protein, ~2 ppm Fe (LPI) diet for 21 days. During the 14 day repletion, five groups of rats (n = 8) were fed diets supplemented with Acheta domesticus (cricket, ADO), Rhynchophorus phoenicis fabricius (palm weevil larvae, RFA), STO, ADO STO (TAD), and casein ferrous sulfate (PIS, positive control), as well as a non-supplemented group (negative control, LPI). A normal (NOM) group was fed protein-Fe sufficient (PIS) diet throughout the study. Body composition was measured by Dual-energy X-ray absorptiometry. The hemoglobin (Hb) repletion method was used to assess relative biological value (RBV, compared to PIS) of the supplemented groups. No differences were found in weight gain, bone mineral content, lean and fat mass, and organ weights among the edible insects and PIS groups, but these results differed from STO and the LPI groups. An increase in Hb Fe and RBV with ADO and RFA was comparable to PIS. ADO and RFA could be excellent sources of protein and bioavailable Fe, making it a sustainable, low-cost food source to prevent malnutrition in humans.
