A pound of oysters supplies about 245 calories of energy, 28 grams (about 1

 grams of iron. It would furnish, therefore, 7 per cent of the energy a man 

 needs daily, 28 per cent of the protein, 35 per cent of the calcium, 53 per cent 

 of the phosphorus, and 136 per cent (more than all) of the iron. This is shown
