Poor Grammar

In my continuing quest for perfect use of the Queen's English, I report that I have found yet another example of poor grammar in retail signage. This image was taken in one of those healthy fast food stores that I hope know more about making fresh food than they do about grammar.

The error in case you can't pick it, is the lack of a comma after the word 'and', as underlined in red. Without the comma, the sentence implies a stronger link between the words fatigue and confusion. The intention of the writer is to give equal weight to all three words in the list; depression, fatigue, and confusion. To give a stronger link between the latter two would simply not make sense.
