"Crickets have long been eaten in Japan, and we see them as potentially an important and useful resource," Fumiya Aokubu, a spokesman for the company, told DW. "Raising crickets is environment-friendly. It requires very little land, water or feedstock, while the food conversion rate is far superior to livestock such as pigs, beef cattle or chickens." [...] The research has so far determined that crickets are high in calcium, magnesium, zinc, iron, vitamins and dietary fiber. Additionally, crickets can be processed into cosmetics and pharmaceutical products, as well as fertilizers.
