It all depends, doesn't it.
'I don't like veg much, but I force it down for health reasons.' Manageable.
'I have real problems with the taste, smell and texture of some foods, but I know this is an issue and I've worked hard to make sure I have a healthy diet in spite of this. I'm happy to eat out with friends and family as long as everybody understands sometimes I won't be able to eat much, and it's nice when nobody makes a big deal out of this.' Manageable.
'I can't stand veg and eat none at all. Ketchup is OK as you can't really tell it's got tomatoes in it. When I eat out or get a takeaway it has to be somewhere I can get the really plain, veg-free food I like. KFC is OK. Most other restaurants and cafes aren't. I never touch Chinese or Indian or Italian food or anything like that because they put vegetables in everything and it's rank. If you eat things like that I'll constantly be sniping from the sidelines about how bad it all looks and smells, and making vomit noises.' Unmanageable.
