The food crisis and food security are becoming increasingly dire, with the expansion of traditional agriculture and animal husbandry proving unsustainable. Edible insects, rich in protein, fats, minerals, and other nutrients, offer a viable solution to diversify diets and enhance food security. To promote the application and development of edible insects, it is essential to address food safety concerns, including allergic reactions and heavy metal contamination, while also working to improve consumer acceptance. This paper explores the nutritional value of edible insects and delves into the prospects of their development, considering benefits, applications, safety, and consumer acceptance. It serves as a valuable reference for advancing food and feed practices.
