The line graph illustrate the proportion of using whole milk and low-fat milk in the United States from 1970 to 2015.
Overall, the figure for consumption of low-fat milk in the United States had the highest over the period, while the opposite was true for that of low-fat milk. In addition, the per capita consumption of whole milk witnessed a significant decrease between 1970 and 2015, while the figure for using low-fat milk in the United States from 1970 to 2015 increased considerably.
On the one hand, about 7% was recorded by the per capita consumption of low-fat milk in the year 1970, 5 times lower than that of low-fat milk, reaching the peak at approximately 25%. After 20 years, while the percentage of consuming whole milk saw a significant decline, from around 25% in 1970 to around 13% in 1990, the figure for that of low-fat milk increased considerably, from around 7% to around 13% between 1970 and 1990 which was the time that whole and low-fat milk had the same figures.
On the other hand, in United States, between 1990 and 2010, the figure for using low-fat milk stayed unchanged at around 13%, while that of whole milk continued decreasing sharply to about 7%, twice as low as low-fat milk. Afterwards, in the year 2015, the per capita consumption of low-fat milk fell slightly, from about 13% to 12%, and the figure for whole milk hit the lowest point of 5% in United States.
