SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`foodsuggestion

I have a table Food having fields:

• FoodID(PK)
• FoodName
• CategoryID(FK)
• ResID(FK)

And other table is Restaurant having fields:

• ResID(PK)
• ResName
• FoodID(FK)

When I insert data to any table it gives error like:

SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (foodsuggestion.restaurant, CONSTRAINT restaurant_food_id_foreign FOREIGN KEY (Food_id) REFERENCES food (Food_id)) Where is the problem in my DB?I am using llaravel.
