Calcuim is a low probability typo for calcium, found 7 times in OHIOlink. The mineral itself has a high probability of affecting your health: it’s the mineral most likely to be undersupplied in a person’s diet.
High levels of Calcium can be found in dairy products, seafood, and vegetables like broccoli. That leafy green member of the mustard family is native to the Mediterranean, and has been cultivated there since Ancient Rome.
Did the Romans know of broccoli's health properties? I can't say I'd choose to eat it otherwise. And now I’m picturing Agrippina telling the young emperor Nero that he can’t leave the table until he’s finished his broccoli. The reason why Rome burned, perhaps?
