Not only are insects a more resource-efficient food source than meat (and more nutritious, to boot), you're also already eating them, writes Mary Hall at Mind the Science Gap. Insect parts are considered unavoidable, natural "defects" in foods and the FDA makes allowances for them, including up to 30 insect parts per average chocolate bar, up to 10 whole aphids for 2.5 cups of spinach, and up to 10 fly eggs (or, if you prefer, 5 eggs and one maggot) per serving of tomatoes. It all sounds gross, but when you consider all the benefits of bug eating (and the fact that many, many reviews proclaim them to taste delicious) it might be best to think of this news as a wakeup call. You're eating bugs already. Why not do it intentionally?
