Human dietary patterns are a major cause of environmental transformation, with agriculture occupying ~ 50% of global land space, while food production itself is responsible for ~ 30% of all greenhouse gas emissions and 70% of freshwater use. Furthermore, the global population is also growing, such that by 2050, it is estimated to exceed ~ 9 billion. While most of this expansion in population is expected to occur in developing countries, in high-income countries there are also predicted changes in demographics, with major increases in the number of older people.

Moreover, edible insects contain iron concentrations similar to meat, potentially making them a valuable iron source for human consumers. Yet, it is unknown to what extent iron from insects is absorbed in humans.

Although the four cricket species were reared in identical conditions, two-spotted & banded crickets had a lipid content 1.5 fold higher than house cricket.

The aim of this small-scale study was to determine if a high UVb irradiance would affect an increase in plasma vitamin D concentrations in Burmese pythons ( Python bivittatus). There have been inconsistent results throughout the literature concerning the usefulness of UVb radiation regarding vitamin D synthesis.

Edible insects, of which a diversity of over 2000 species is available, are dietary components for about 2 billion individuals and are a valuable source of animal protein. In the present paper, we review the available information on Fe and Zn in edible insects and their potential as a source of these micronutrients for the rapidly growing human population.

This study aimed to evaluate the tolerance and accumulation of AFB1 in two insect species to determine whether they could be used to retain condemned mycotoxin contaminated crops in the food chain. First, instar black soldier fly larvae (, BSF) and yellow mealworm (, YMW) were fed poultry feed spiked with AFB1 and formulated to contain levels of 0.

Insects are suggested to efficiently convert feed to body mass and might therefore form a more sustainable food and/or feed source. Four diets were composed from by-products of food manufacturing and formulated such as to vary in protein and fat content.

Producing edible insects on diets composed of organic by-products could increase sustainability. In addition, insect growth rate and body composition, and hence nutritional quality, can be altered by diet.

The present study evaluated the protein quality of a selection of insect species. Insect substrates were housefly pupae, adult house cricket, yellow mealworm larvae, lesser mealworm larvae, Morio worm larvae, black soldier fly larvae and pupae, six spot roach, death's head cockroach and Argentinean cockroach.

Edible insects are suggested as a more sustainable source of animal protein. However, few experimental data regarding environmental impact of insect production are available.

The livestock sector is one of the large contributors of anthropogenic GHG emissions. Also, large amounts of ammonia (NH(3)), leading to soil nitrification and acidification, are produced by livestock.
