Crickets are a nutritional powerhouse. They contain all 10 essential amino acids, as many omega-3s and more vitamin B12 than salmon, more iron than spinach, more calcium than a glass of milk, as well as chitin, a gut-friendly prebiotic.
As a bonus, they're one of the most efficient sources of animal protein - using fractions of the resources used by traditional protein sources, while producing virtually no greenhouse gases.
