Aparently everything tastes wrong when you've just regenerated. Also, maybe fishfingers and custard is nice. Have you ever tried it? When I was little I liked corned beef and custard, which is very close.
And maybe regenerating Time Lords can have mineral deficiency related cravings, just like some pregnant women (both have to build a new body, after all). The Doctor didn't seem all that worried by the phenomenon, he just said that it never happened to him before.
