(more than £ ounce) of protein, 0.55 gram of calcium, 0.43 gram of phosphorus, 
and 1 milligram of iron. It would furnish, therefore, 5 per cent, of the energy 
a man needs daily, 15 per cent of the protein, 81 per cent of the calcium, 33 
per cent of the phosphorus, and 8 per cent of the iron. This is shown in the

Chart 21. One Pound of Cottage Cheese. 
(1£ cups packed solidly.) 
One pound of cottage cheese supplies about 490 calories of energy, 95 grams 
(about 31 ounces) of protein, 0.45 gram of calcium, 1.5 grams of phosphorus, 
and practically no iron. It would furnish, therefore, 14 per cent of the energy a 
man needs daily, 95 per cent of the protein, 67 per cent of the calcium, 112 
per cent (more than all) of the phosphorus, and none of the iron. This is
