Excerpts from the report Summary: In the past 10 years there has been a sharp upturn nationally in home use of nonfat dry milk, while total use of fresh milk has been relatively stable and consumption of evaporated milk has fallen off markedly. The patterns of milk purchases of 477 families in the Chicago metropolitan area were studied over a 3-year period. Milk purchases of families who used nonfat dry milk were compared with those of families who did not use it. The analyses showed that families who purchased nonfat dry milk increased their total milk product purchases more than families who did not use it. The study also indicated that purchases of nonfat dry milk resulted in increased total milk consumption with little effect on purchases of fresh milk. There was practically no substitution between nonfat dry milk and evaporated and filled milk in the home. Data on purchases of nonfat dry milk, fresh fluid milk, evaporated milk, and filled milk were also analyzed to ascertain relationships between consumption patterns and family characteristics such as income, race, and size of family.
