Research into edible cricket consumption has shown that insects are safe to eat as long as they are properly processed like other animal products. Cricket protein is on my lists of the best protein powders for pregnancy and the best clean protein powders. Some people, however, may be allergic to insect proteins and chitin (a fibrous substance that makes up part of the exoskeleton of the cricket). Crickets or cricket protein powder should also be avoided if you have a crustacean shellfish allergy because they are arthropods like crabs, lobsters, and shrimp. It is a good idea to speak to a medical professional before trying cricket protein powder if you have any allergy concerns.
