About this trial

The purpose of this study is to determine the health impacts of consistent consumption of insect-fortified crackers among school-aged children in Madagascar.

Specifically, in this RCT, the investigators will assess whether the insect-fortified crackers can improve the health status of Malagasy school children. The investigators' objectives are to: (1) Assess changes in gut microbiome composition that occur after 6 and 14 weeks of cracker consumption through 16S rRNA sequencing. (2) Assess changes in intestinal and systemic inflammation after 6 and 14 weeks of cracker consumption through quantification of fecal calprotectin, lactoferrin, myeloperoxidase (MPO), and alpha-1-antitrypsin (AAT) and circulating pro-inflammatory cytokines. (3) Assess changes in iron status after 14 weeks of cracker consumption through quantification of hemoglobin (Hb), inflammation-adjusted serum ferritin, and soluble transferrin receptor (sTfR).
