"Quality nutrition" is any scientifically backed research results on good health.

Here is a resource that uses research to back up its claims: https://www.efsa.europa.eu/en/topics/topic/dietary-reference...

And it has a good tool to find and meet those results: https://multimedia.efsa.europa.eu/drvs/index.htm

The comment I was replying to made a specific claim that I was referring to.

Regarding your definition of quality nutrition, you'll have to be more specific. You can find scientific research to support nearly any dietary choice.
