No. 4.] FOOD VALUE OF DAIRY PRODUCTS. 181 



If a person consumed only four quarts of milk in one day, 

 he would have taken enough food to work on, but slightly 

 more protein than was necessary, and be a little deficient in 

 the fuel foods. Substituting 16 ounces of wheat bread for 

 one quart of milk would be an improvement.

The wheat bread and milk ration would not be far out of 

 the way, — nearer to the demands of the system than 2 

 pounds of sirloin steak. 



Change now from wheat bread to 16 ounces of corn meal 

 and we have yet nearer a sufficient, well-balanced ration.

Two pounds of corn meal has .20 of a pound of protein 

 and 3,300 calories, and if in making that into bread water is 

 used, nothing is added to its nutritive value. Suppose, how- 

 ever, we mix with it a quart of milk, and we have —

This is just the right amount of protein and an excess of 

 fuel foods. If we used skim-milk the result would be better.
