I have heard the rule is that if it's the food you're selling, it has to be real. But if you have some extra stuff in there (suppose you're selling a topping or something like that), that stuff can be fake food because it's not the food being advertised. One story that I read somewhere involved opening 50 frozen dinners and picking the 20 or so very best peas for the photographs. Technically each pea came from the actual product! So they seem to go to some lengths to obey the rules, even if it involves some bending.
