What was the cause of food and other items being put into the tombs?

Hi !

Here is your answer !

The wall paintings portraying scenes from daily life show how the food was consumed, at least among the wealthier classes. Bread and beer were staples in ancient Egypt and they are also the products most frequently found in the tombs.

(Sorry no explanation in this question)
