To me a probable yes!
I've got a bloody cold and can't smell or taste sod all at the moment, fleeting but just down right irritating. I had a thought that even though I remember how good things taste and smell, it's just not satisfying at all.
I know there are plenty of tasty healthy things but I'd rather chow down on a chocolate bar and a glass of plonk while watching the soaps than chewing through a salad of an evening. If I can't really enjoy the taste well I may as well eat all the pumpkin seeds and tofu I can get my mitts on.
I haven't had either of those things but just a thought.
