We eat living organisms be it plants or animals. (Ofcourse, we kill them first!) All that we eat is made of cells and/or its broken-down products. And, each cell contains proteins, polysaccharides, and nucleic acids (major macromolecules).
Therefore, our food is bound to contain more than one type of macromolecules.

"Foods" is a very vague term, and therefore does not need to remain consistent. A "food" is often a combination of different things. For example: A cheeseburger is considered a food, and contains many parts (bun, patty, cheese, lettuce, etc.). Each of those have very different molecular structures, making it completely logical that foods consist of multiple types of macromolecules.

Steak has both carbohydrate and protein. Its possible because of the animal's glycogen contributes to the carbohydrate in the meat.
