The given line graph illustrates the per capita consumption of whole milk and low-fat milk in the United States between 1970 and 2015, measured in gallons.
At the onset, it is clear that whole milk consumption showed a significant decline, while low-fat milk became increasingly popular and eventually surpassed whole milk.
In 1970, whole milk consumption was the highest at over 25 gallons per person, but it continuously decreased throughout the period, reaching just over 5 gallons in 2015. In contrast, low-fat milk started at around 6 gallons in 1970 and rose steadily to nearly 15 gallons by 1990. This level of consumption remained stable for the next two decades before slightly declining towards the end of the period.
By 2015, low-fat milk had become the more commonly consumed type, indicating a clear shift in consumer preferences towards healthier options.
