Deletion of Essential nutrient

Comment: The term "essential nutrient" is used throughout the medical and scientific literature.  Google Scholar finds many thousands of articles that use the term. A PubMed search finds thousands of articles that include "essential nutrient" in either the title or the abstract.  Essential nutrient is linked from dozens of other Wikipedia articles. I don't think the argument that this is a "non notable subject" is viable. There appears to have been problems with prior versions of the article (the text of which has recently been removed) which may have conflated multiple meanings of the term or included original research, but surely there is a way to write a -compliant article on this topic
