Chart 28. One Pound of Fresh Salmon. 
One pound of fresh salmon, as purchased, supplies about 630 calories of 
energy, 69 grams (about 2\ ounces) of protein, 0.07 gram of calcium, 0.8 gram 
of phosphorus, and 4 milligrams of iron. It would furnish, therefore, 18 per 
cent of the energy a man needs daily, 69 per cent of the protein, 11 per cent of 
the calcium. 60 per cent of the phosphorus, and 25 per cent of the iron. This is

Chart 29. One Pound of Oysters. 
(About 1 pint.) 
A pound of oysters supplies about 245 calories of energy, 28 grams (about 1 
ounce) of protein, 0.2 gram of calcium, 0.7 gram of phosphorus, and 20 milli- 
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
