I daresay that this lack of interest in work is due to different matters (i.e. the nature of an individual's work, management techniques); and food acquisition is only one of its outlets/manifestations. But perhaps it varies across departments--in which case I am sorry to hear that you have non-productive and unmotivated individuals working with you.
I also sincerely do hope that you are leaving most of this meal planning to an actual healer since your intelligence is not altogether convincing and I still believe you are an utter control freak the planning of diets are more than just choosing proteins and healthy fats. (Yes, there is such thing as good carbohydrates, Malfoy.)
Well I commend you for your pointless advocacy, Malfoy. Even though I'm still quite convinced that I will not hold any interest in food at the canteen, I'm sure that it will do plenty of good for vegetarians within the Ministry.
