I'm assuming a Western context, and that fruit and vegetable have their common language and culinary meanings, so that e.g. tomato and cucumber are vegetables, and that "fruits" generally means what is available to and consumed in most Western contexts. This seems reasonable given the article.

Avocado I don't personally consider to be either fruit or vegetable (it is a "tree fat"), and is more in the category of things like olives or seeds / nuts, in culinary and nutritional terms too. Calling avocado a fruit or vegetable feels extremely awkward, as does calling things like olives, capers, or, say, fresh green peppercorns. Starchy / root vegetables are not really what is meant by "vegetables" in these discussions either.

And yes, tropical fruits and berries actually have meaningful nutrients, and are better choices.
