Edible insects are considered as an alternative source of proteins, but in addition are also rich sources of minerals. However, no studies have investigated the bioavailability of minerals from edible insects in humans. House cricket (Acheta domesticus) is an edible insect species that is commonly consumed in low and middle income countries where the prevalence of iron deficiency and anaemia is relatively high. We aimed to assess the fractional iron absorption of iron from house crickets in humans after addition to either a refined (low-phytate) or a whole meal (high-phytate) maize porridge meal. A second objective was to assess the fractional iron absorption from maize porridge meals when crickets were added.
