The chart illustrates two kinds of milk intake per resident in the United States over a 45-year period from 1970 to 2015.
On the whole, whole milk was the dominant option for Americans in 1970; however, it has lost its position in a few decades and has been substituted by low-fat milk at the end of the term. The shift can be explained by multiple factors, including the modern generation’s aspiration to pursue a healthy lifestyle; subsequently, the popularity of low-fat milk grew significantly. Overall, the dynamics indicate change in preferences for the majority of citizens.
In 1970, the average person consumed just over 25 gallons of whole milk, which is two times the amount of low-fat milk – 7 gallons.
Throughout the following two decades, whole milk underwent a considerable plummeting, reaching the scale of approximately 14 gallons per capita. Meanwhile, low-fat milk experienced a great rise; as a result of preceding modifications, lines have intersected.
While low-fat milk hit a plateau, and since then remained relatively stable at 14-15 gallons, whole milk has maintained a dip trajectory, reaching 6 gallons in 2015.
