Which dairy product had the largest increase in per capita consumption?

The correct choice is yogurt, as it has experienced significant growth in per capita consumption over recent years. This increase can be attributed to several factors, including health trends favoring probiotic-rich foods, the rise of Greek yogurt as a popular choice, and its versatility as both a snack and an ingredient in various recipes. Consumers are increasingly aware of yogurt's health benefits, such as improved digestion and its role in a balanced diet, which has contributed to its rising popularity.

The other options, while also enjoyed by many, have not seen the same level of dramatic increase in per capita consumption. Cheese consumption has remained relatively stable, driven by its integration into numerous cuisines, but it has not surged to the same extent as yogurt. Butter, despite its resurgence in some circles, primarily due to shifts in dietary trends, has not matched yogurt's growth. Ice cream consumption tends to fluctuate seasonally and is impacted by dietary choices and preferences for healthier alternatives, resulting in a more modest increase compared to yogurt.
