Can anybody say something definite on the topic?
Some sources say that an eggshell is a good source for calcium for bones and teeth and advice it.
When I used to go in for power-lifting I consumed nearly half an eggshell (from a boiled egg) a day for many months and don't think it was harmful.
My wife is pregnant now. Will it be good for her to consume grounded eggshells?
What's your opinion? Thanks a lot.
