Terms healthy and proper diet are often interchanged freely. In practice, there’s no difference, but I’d like to write a few words on their meanings. Up until recently I avoided the term healthy and utilized the term proper, simply because I hadn’t completely made up my mind on what the definition of health should be. I still haven’t, but sometimes you need to compromise.
I hope that the question mark at the end of this tedious cliché made you click the article and read it. I’ve always had an issue with this statement. It is so widespread among fellow nutritionists, doctors, and of course, laymen journalists, that it is often posed (and, unfortunately, used) as the motto of nutrition science.
