Answer:
Cultural and family background effect food choices tremendously. Every culture has its own specialty in terms of food and every family has their own traditions. Food is close to peoples hearts and it binds them together.
For example Mexico is famous for spicy food and pastas in particular, Pakistanis are famous for desi food. Families have famous turkey recipes that go down through generations.
So whenever someone travels somewhere, they look for familiar flavors that bind them to their culture and family backgrounds.
