Chart 10. One Pound or Green Corn, Canned. 
(if cups.) 
One pound of green corn, canned, supplies about 455 calories of energy, 13 
grams (a little less than | ounce) of protein, 0.14 gram of calcium, 0.5 gram 
of phosphorus, and 3 milligrams of iron. A pound of cooked fresh corn cut 
from the cob would supply practically the same quantities. Either would 
furnish, therefore, 13 per cent of the energy a man needs daily, 13 per cent 
of the protein, 21 per cent of the calcium, 38 per cent of the phosphorus, and 
21 per cent of the iron. This is shown in the following chart :

Chart 11. One Pound of Tomatoes, Canned. 
(11 cups.) 
One pound of tomatoes, canned, supplies about 105 calories of energy, 5 
grams (about i ounce) of protein, 0.06 gram of calcium, 0.1 gram of phos- 
phorus, and 1.8 milligrams of iron. It would furnish, therefore, 3 per cent 
of the energy a man needs daily, 5 per cent of the protein, 9 per cent of the 
calcium, 8 per cent of the phosphorus, and 12 per cent of the iron. This is
