I really hate when students (and I assume is is a homework/tutorial
exercise) get asked to write bad code. This function should be
entirely unnecessary. The function for creating instances is the
constructor - it's already written. We don't need another.

And the Pythonic way of building lists is a list comprehension.
So this whole exercise should be reduced to:

food_list = [Food(t) for t in tuple_list]

If we are going to teach objects lets use the objects!
