Cross join enquiry, duplicate

ALTER PROCEDURE Inventory
AS
BEGIN
INSERT INTO Inventory (FoodID, FoodName, ItemID, ItemName)
Select DISTINCT f.FoodID, f.FoodName, i.ItemID, I.Name from Food f CROSS JOIN Item i
WHERE f.FoodID=i.ItemID
END

Food Item Inventory
FoodID ItemID FoodID, ItemID

Right now, there's duplicate in cross join.

Can you other joins or any methods?
