According to ERS’s loss-adjusted food availability data, Americans consumed just under 1.5 cup-equivalents of dairy products per person per day in 1974 and in 2014—half the recommended amount for a 2,000-calorie diet. While Americans are consuming the same number of cup-equivalents of dairy products, the mix has changed.
Consumption of cheese has more than doubled during this time from 0.29 cup-equivalents per person in 1974 to 0.64 cup-equivalents per person in 2014, while yogurt consumption grew almost ten-fold to 0.05 cup-equivalents per person.
Fluid milk consumption stood at 0.55 cup-equivalents per person in 2014, down from 0.90 cup-equivalents per person in 1974. Several factors have contributed to this decline, including competition from soft drinks, fruit juices, bottled water, and other beverages; generational differences in the frequency of milk drinking; and a more ethnically diverse population, some of whose diets do not normally include fluid milk.
