How many servings of vegetables is an onion?

It's tricky to say how many servings an onion is because it depends on the size of the onion and how it's used.

Here's why:

* Serving size varies: A standard serving of vegetables is considered to be 1 cup raw or 1/2 cup cooked.

* Onion size: Onions come in different sizes, from small pearl onions to large Spanish onions.

* How it's used: A whole onion might be one serving if you're using it in a large pot of soup. But, if you're having a small portion of onion rings, it might be just a fraction of a serving.

To estimate:

* Small onion: About 1/4 to 1/3 cup chopped, roughly 1/2 serving.

* Medium onion: About 1/2 cup chopped, roughly 1 serving.

* Large onion: About 3/4 cup chopped, roughly 1.5 servings.

Key takeaway: It's not about the exact number of servings but about including onions as part of your daily vegetable intake.
