Why eat bugs when you can eat a hamburger? They’re a better source of iron, Scientific American reports. (And they’re higher in protein, too.) Scientists tested the iron content of grasshoppers, crickets, mealworms, and buffalo worms. Crickets won that round. Then they tested how easily each could be absorbed by a human digestive system and found buffalo worms were best, even surpassing sirloin steak, according to the study published in the Journal of Agricultural and Food Chemistry this week. Researchers have studied the benefits of tapping into insects as a source of nutrition for environmental reasons, including reducing greenhouses gases produced by livestock or as an alternative food source for livestock as well. Though don’t expect “pestaurants” popping up anytime soon, but if you fancy yourself a creepy-crawly connoisseur, there’s a whole YouTube channel dedicated to bug burgers.
