From the “in a word, no” department and the AMERICAN CHEMICAL SOCIETY comes this same tired old story we keep hearing from eco-activists tht believe bugs are more “sustainable” than beef. Because cattle make methane, and that will set the world on fire someday.
The buzz about edible bugs: Can they replace beef?
Edible bugs might sound unappetizing to many Westerners, but they’ve long been included in traditional diets in other regions of the world, which are now home to more than 2 billion people, according a report by the U.N. Food and Agriculture Organization. The report also notes that about 1,900 insect species have been documented as a food source globally. That they’re a source of protein is well established, but if the world is to turn to bugs to replace meat, the critters will need to offer more than protein. Iron is a particularly important nutrient that is often missing in non-meat diets, causing iron-deficiency anemia, which can lead to lower cognition, immunity, poor pregnancy outcomes and other problems. In light of these concerns, Yemisi Latunde-Dada and colleagues wanted to find out whether commonly eaten insects could contribute to a well-rounded meal.
The researchers analyzed grasshoppers, crickets, mealworms and buffalo worms for their mineral contents and estimated how much of each nutrient would likely get absorbed if eaten, using a lab model of human digestion. The insects had varying levels of iron, calcium, copper, magnesium, manganese and zinc. Crickets, for example, had higher levels of iron than the other insects did. And minerals including calcium, copper and zinc from grasshoppers, crickets and mealworms are more readily available for absorption than the same minerals from beef. The results therefore support the idea that eating bugs could potentially help meet the nutritional needs of the world’s growing population, the researchers say.
