My question is, why is dairy unpopular as part of the East and South Asian diet?

Thanks in advance

Many Buddhists eat no animal products so they shun dairy products. Another -- more practical reason -- is that East and South Asia doesn't have much land to feed dairy cattle.

The unpopularity of dairy as part of the East and South Asian diet can be attributed to several reasons including historical, cultural, and physiological factors.

1. Historical and Cultural Factors: Dairy consumption has been traditionally low in East and South Asian countries due to a lack of historical tradition and cultural practices. Unlike in the Western world, where dairy farming has been prevalent for centuries, the tradition of raising cattle for milk production has been relatively limited in many Asian countries. As a result, dairy products were not a significant part of the traditional Asian diet.

2. Lactose Intolerance: Many East and South Asians genetically have a higher prevalence of lactose intolerance compared to populations of European descent. Lactose intolerance is the inability to digest lactose, the sugar found in milk and dairy products, due to a deficiency of the enzyme lactase. This can lead to digestive discomfort, such as bloating, gas, and diarrhea, after consuming dairy products. The prevalence of lactose intolerance varies among Asian populations, with some countries having higher rates than others.

3. Dietary Alternatives: Due to limited historical consumption of dairy, Asian cuisines have developed a wide array of alternative sources for necessary nutrients found in dairy products. These alternatives include tofu, soy milk, rice milk, and various plant-based sources of calcium and protein. These alternatives are often preferred and commonly used in Asian cooking and food preparations.

4. Taste and Texture Preferences: The taste and texture of dairy products may also play a role in their unpopularity in certain Asian cultures. Dairy products such as milk, cheese, and butter have distinct flavors and textures that may not be as familiar or appealing to individuals who did not grow up consuming them. This can further contribute to a general lack of interest and consumption of dairy products.

It's important to note that while dairy may be less popular in East and South Asian diets, there are variations within different Asian countries and among individuals. Some people in these regions do consume dairy products regularly, and with globalization and cultural exchange, the consumption of dairy is increasing in certain Asian countries.
