MORE CALCIUM IN EGGSHELL THAN MILK
WHY should I eat them?
Eggshells are exceptionally high in the mineral calcium, essential for building bones, teeth and nails. One 2013 study by researchers in Argentina found that just half a large shell could provide the entire daily recommended calcium intake of roughly 700mg per day. One glass of milk contains roughly a third of this.
HOW do I eat them?
They must be sterile before eating to prevent the risk of salmonella, sometimes carried in raw eggs. This is easily achieved by soaking them in boiling water, or roasting in a hot oven. Then, crush into a powder and add them to food for a calcium boost.
‘The best way to use eggshell is powdered and added to bread, pizza or spaghetti,’ say scientists at Rosario University in Argentina. ‘There are small changes in texture and no changes in flavour.’
