Which dietary group restricts both pork and few dairy products?

The correct choice signifies the dietary practices commonly associated with certain cultural and religious beliefs. The Southeast Asian dietary group, particularly among certain populations, might restrict pork due to cultural taboos and consider dairy, particularly whole milk, less desirable because of lactose intolerance prevalent in those regions. This aligns with the values and traditional dietary restrictions found within those communities.

For clarity, it's important to understand that while Kosher dietary laws prohibit pork, they do not restrict all dairy, and instead, they have specific rules about how dairy and meat can be consumed together. Seventh Day Adventists do have some dietary restrictions, including avoiding pork, but they primarily emphasize a vegetarian diet, which may or may not include dairy products. Roman Catholics don’t typically have restrictions on pork or dairy, although dietary choices can vary widely among individuals.

Therefore, the Southeast Asian group is uniquely characterized by restrictions that encompass both pork and certain dairy products, making it the best fit for the question.
