联合国：多吃昆虫有助对抗饥荒Eating more insects could help fight world hunger, according to a new UN report. 联合国一份新报告中指出，多吃昆虫可以帮助对抗世界饥荒。Over 2 billion people worldwide already supplement their diet with insects The report by the UN Food and Agriculture Organization says that eating insects could help boost nutrition and reduce pollution. It notes than over 2 billion people worldwide already supplement their diet with insects. However it admits that "consumer disgust" remains a large barrier in many Western countries. Wasps, beetles and other insects are currently "underutilised" as food for people and livestock, the report says. Insect farming is "one of the many ways to address food and feed security". "Insects are everywhere and they reproduce quickly, and they have high growth and feed conversion rates and a low environmental footprint," according to the report. Nutritional value The authors point out that insects are nutritious, with high protein, fat and mineral content. They are "particularly important as a food supplement for undernourished children". Insects are also "extremely efficie nt" in converting feed into edible meat. Crickets, for example, need 12 times less feed than cattle to produce the same amount of protein, according to the report. Most insects are are likely to produce fewer environmentally harmful greenhouse gases than other livestock. The ammonia emissions associated with insect-rearing are far lower than those linked to conventional livestock such as pigs, says the report.
