Question

2. People all over the world love eating street food.

3. People all through the world love eating street food.

4. People all throughout the world love eating street food.

(Are they all grammatical? What other expressions can we use instead of 'all around the world'? Which expressions are commonly used? Thank you.)

Answer 1

1, 2, and 4 seem fine to me, but I'd omit 3.
