The reason why you should be eating your eggshells - and how to prepare them safely

Each year in the US alone, Business Insider reports, the food industry is responsible for 150,000 tons of shell waste.

We automatically bin our shells when making anything involving eggs .

But instead of throwing them away, we should give some serious thought to eating them.

Not just because of the environmental benefits, but also because of their nutritional value.

One single egg shell contains around two grams of calcium which works out as being between two to four times our recommended daily allowance.

This, however, is not a call to start mainlining raw eggshells.

That would be silly.

Instead, boil the shells to blitz any harmful bacteria. After the shells are nicely boiled, you then bake them in the oven for 15 to 20 minutes with the temperature turned up to 200F.

They should then grind nicely into a fine powder, which you can do in a blender.

The powder remains a good source of calcium and has been shown to reduce pain and bone loss in women with senile osteoporosis.

You don't need to eat the powder on its own.

It can be added to foods such as bread, pizza dough and spaghetti.

But be cautious.

Too much or too little calcium can be dangerous, with the average adult needing just one gram per day.
