themselves reported that in Arabia locusts were eaten frequently and one Arab described to a European traveler the different types of locusts which were favored as food by Arabs. Persians use the Anti-Arab racial slur Arabe malakh-khor (, literally "Arab locust eater") against Arabs. Locusts yield about five times more edible protein per unit of fodder than cattle, and produce lower levels of greenhouse gases in the process. The feed conversion rate of orthopterans is 1.7 kg/kg, while for beef it is typically about 10 kg/kg. The protein content in fresh weight is between 13 and 28 g / 100 g for adult locust, 14–18 g / 100 g for larvae, as compared to 19–26 g / 100 g for beef. The calculated protein efficiency ratio is low, with 1.69 for locust protein compared to 2.5 for standard casein. A serving of 100 g of desert locust provides 11.5 g of fat, 53.5% of which is unsaturated, and 286 mg of cholesterol. Among the fatty acids, palmitoleic, oleic, and linolenic acids were found to be the most abundant. Varying amounts of potassium, sodium, phosphorus, calcium, magnesium, iron, and zinc were present.
