Which of the following best analyzes how something becomes a staple food?

1. It is the result of mixing foodways through globalization.
2. It is a healthy food with lots of vitamins and nutrients.
3. It is widely available in the region and is high in calories.
4. It is a food that is acceptable in the religious culture of a region

I would choose option 3. "It is widely available in the region and is high in calories." This option captures the idea that a staple food is one that is accessible and provides a significant amount of energy. A staple food is typically a main dietary component that serves as a major source of calories for a particular population or region.
