I was the same, apart from spuds never are veg until in my 20s. No diary,no fish no fruit (still don't eat fruit because I genuinely don't really like it). It's pissed my dad, the greengroucer off!
I have tried lots of foreign food. Most I enjoy. Fave cuisine Italian, love Indian, Mexican is ok, as it Thai and Chinese, French is hit and miss in my opinion, German is great.
I really really hate fish and shellfish....it's both the taste and texture.
