In a previous publication1 a similar experiment in the nutrition of children from 7 to 15 years old was reported. These two papers, therefore, present one complete study with the same types of food from the beginning of pregnancy up to the 15 year old child, allowing for the interval between the ages of 2 years and 3 months, and 7 years.
With the rapid progress in the science of nutrition a great deal of literature has appeared concerning the diet of the pregnant and lactating mother and that of the nursing infant.
The conclusion from various sources has been that during pregnancy, lactation and growth, an otherwise adequate diet should be fortified with approximately 1 quart (946 cc.) of cow's milk a day, especially for its content of calcium and phosphorus, and also for protein and vitamin A.
But it has been my conviction from many clinical studies
