| Protein | 8 g | 1 g | 7 g |
| Calcium | 300 mg | 450 mg (fortified) | 300 mg (fortified) |
| Vitamin D | 2.4 mcg | 2.5 mcg (fortified) | 1.2 mcg (fortified) |
While plant-based options can be fortified with essential nutrients, they may not naturally provide the same amounts as dairy unless fortified.
Exploring Cultural Perspectives on Dairy
Dairy foods also hold a significant place in various cultures around the globe, contributing not just nutrition but also flavor and tradition.
Dairy in Different Cuisines
From Greek yogurt to Indian paneer, dairy plays a role in diverse culinary traditions. Each culture utilizes dairy in unique ways that reflect local agriculture, climate, and dietary needs.
- Mediterranean Diet: Known for its health benefits, this diet includes yogurt, cheese, and milk, emphasizing moderation and health.
- Asian Cuisine: In many Asian countries, fermented dairy products like yogurt and kefir are integral to meals, promoting gut health.
Embracing Dairy’s Global Influence
Understanding the role of dairy in various cultures can enhance our appreciation for these foods and encourage diverse culinary practices in modern diets.
