Alternative to Jam?

I have never tried it but what about nutella

I don't use jam, I normally take frozen fruit (preferably strawberries or mixed berries) that you can purchase from any grocery store, let the amount I'm going to use thaw out and blend it to make my own jam. I use it on french toast, pancakes, regular toast, etc. Be creative and don't limit your self to prepackaged goods.

Tough one if you are trying to avoid sugar altogether. Have you tried any sugar free jams? What about just the almond butter by itself? Or maybe with cream cheese? Normally I would say bananas or raisins, but i don't think that's what you are looking for.

cheese whiz or cream cheese spreads

There are so many alternatives because you can freely choose what foods to eat, that's the beauty of it! Now, if you're looking for something with the taste and consistency of jam, but that isn't jam, I don't know. What about apple butter or some other spread (like Nutella someone else mentioned). I liked the quote that also mentions you could be incorrectly targeting the jam when it may end up being something else, like the preservatives. Good luck on finding your food allergy and a good alternative.

Are you doing the diet under the supervision of a doctor and dietician with additional training in treating patients with severe allergies?

There's a diet that's been developed here in Australia called the Failsafe Diet which is similarly restrictive to your own, but does allow peeled pears. Obviously there's a reason for this, but it's been a while since I've had anything to do with my own allergies that I can't even begin to explain why peeled pears are a-ok. At any rate, I didn't even bother with the diet although I did find a butcher who made delicious Failsafe chicken sausages. They're ace; I still enjoy them from time to time. But peeled pears, that's it, peeled bloody pears. If you can have them then stew into submission and cook down the mush until it's thick and syrupy. Use as jam.

Otherwise you're sol and might want to look into Vegemite. Sure, it's utterly revolting unless you've been brought up on the stuff and is a well known rat and possum poison, but at least it's nice and exotic.

ask about probiotics. they are a wonderful solution for many issues.

like onions, some other veggies caramelize nicely. carrots, sweet potatoes come immediately to mind - you could cook, mash, and spread on a sandwich (we do this with apples and bananas instead of jelly, but I don't see why it wouldn't work with carrots or sweet potatoes.
