40% of calcium. Don't eat chicken, banana, or egg. EAT YOGURT! But, eat more yogurt to get more calcium. You can still eat chicken, banana, or egg. This is just my opinion, it's your choice.
Because egg has calcium coating
The main chemical found in egg shells is calcium carbonate. It provides strength and structure to the shell, helping to protect the developing embryo inside the egg.
calcium carbonate
Oxygen has no softening effect on the calcium compounds found in egg shells. However, acetic acid (vinegar) will cause egg shells to dissolve completely by forming calcium acetate from the calcium carbonate. This will leave the rubbery inner membrane of the egg.
no, the shell does, but the egg itself is high in protein :) hope this helps
Bird-calcium carbonate
The shell is mostly calcium.
mostly calcium
Eggshell structure, varies widely among species, is a protein matrix lined with mineral crystals, usually of a calcium compound such as calcium carbonate . It is calcium build-up and is not made of cells.
Egg shells are made of calcium carbonate, which reacts with hydrochloric acid to form carbon dioxide, water, and calcium chloride. This reaction causes the egg shell to dissolve as the calcium carbonate breaks down into its component parts in the acid solution.
