It may sound sickening to some of you, but many people can and do eat insects. Edible insects are a great source of high quality protein and minerals known to be important to good health, like calcium and iron. Insect larvae, or young, offer all that, as well high quality fat, which is good for brain development. Insects are food in many parts of the world, but not in the United States. In the U.S., concerns about and even fear of the creatures mean serving insects as meals is extremely rare. But that is starting to change. Wendy Lu McGill is opening a shipping container in a community just outside Denver, Colorado. She steps into a little room that is lined with small white boxes. Machines keep the room’s temperature around 26 degrees Celsius. The relative humidity, or level of wetness in the air, is 80 percent. The conditions are just right for the extremely small creatures McGill is raising: mealworms. Rocky Mountain Micro Ranch is Colorado's first and only edible insect farm. We raise crickets and mealworms to sell to restaurants and food manufacturers. The United Nations Food and Agricultural Organization has said that the world’s demand for protein from beef and even chicken is unsustainable. Protein from bugs is one possible solution.
