Egg Yolks, Whites And, Yes, Shells – They’re All Good For You

Eating food waste is a solution to the food loss problem that few people talk about. But one food writer says egg shells, usually tossed in the bin but also increasingly composted, can be processed at home and eaten. There are the obvious environmental benefits to that scheme, but there are also nutritional benefits. The main one being, of course, the essential nutrient calcium, in the form of calcium carbonate. The first step is to boil the shells to rid them of bacteria. Then bake them, grind them to a fine powder, and add to foods such as bread, pizza dough and spaghetti. But be aware that the average adult needs only one gram of calcium a day. More than that can be harmful.
