what does it mean when people say from food to nuts?

Answer 1

From beginning to end. I've always heard the expression: "From soup to nuts." It refers to the courses of a proper meal, beginning with soup and ending with a nut course.

Answer 2

The proper phrase is "from soup to nuts".

"Soup to nuts" is an English idiom conveying the meaning of "from beginning to end". It is derived from the description of a complete meal, whose courses range from soup to a dessert of nuts.

It is comparable to expressions in other languages, such as the Latin phrase ab ovo usque ad mala ("from the egg to the apples"), describing the typical Roman meal.
