The analogy of diet and digital consumption of media is very interesting, but I am intrigued at the use of the word “nutrition”. A tangible association exists between food and physical health. Food is also associated with mental health. Unless we can substantiate an association between mental health and digital consumption of media per se, use of the term nutrition is arguable.
Do some form of digital consumption or certain classes of digital artefacts lead to better mental health status? Does a reduced or excess consumption of these same artefacts lead to worsening mental health status? How do we know? What is the nature of that association? Unless these are unraveled, “digital nutrition” as a concept may be an interesting allegory but will carry little semantic value.
