A speaker argues that spinach is the most nutritious vegetable for a person to eat. A commenter objects that there are many ways to measure nutrition, with some vegetables doing better or worse according to different measurements. What is an effective counter argument for the original speaker to use?

- A well-known nutritionist has said that spinach contains a lot of iron.
- Surely it is rude to suggest that spinach is a terrible vegetable.
- The point is, people should eat more of all kinds of vegetables.
