The line graph illustrates the per capita consumption of whole milk and low-fat milk in the United States from 1970 to 2015.
Overall, it is clear that while the popularity of whole milk fell significantly over the period, low-fat milk showed the opposite trend, eventually becoming more widely consumed.
In 1970, the average American consumed about 25 gallons of whole milk per year, compared to only 7 gallons of low-fat milk. Over the next two decades, whole milk consumption declined steadily, while low-fat milk intake increased. Around 1990, the two figures intersected at roughly 14 gallons.
After 1990, whole milk continued to decrease sharply, dropping to nearly 5 gallons by 2015. In contrast, low-fat milk reached its peak of around 15 gallons in 2000 and then remained relatively stable until 2010, before showing a slight decline to just under 14 gallons in 2015.
In summary, the chart shows a dramatic shift in consumer preference from whole milk to low-fat milk in the U.S., with low-fat varieties overtaking whole milk in the early 1990s and remaining more popular thereafter.
