АЛ, разве food употребляется с неопределённым артиклем? Она ж неисчисляемая!)

You definetly put a fooT wrong here.

да сойдет!

Tatiana, "a food" употребляется
food - еда, пища, питание
foods - пищевые продукты, продовольствие
Potato is a food. Очень лаконично и понятно. )

A food for all occasions is cheese; it could also be said that there is a cheese for all occasions. In mythology we are told that cheese was invented in Greece. It is difficult to say just how many cheeses there are.

... it becomes a food for all tastes and all occassions plus it's really healthy!

AL, здесь food - это "продукт питания", класс продуктов питания.

Друзья, не food, а foot! По логике подходит значение "оступиться" или "ошибиться" :)
