The kiwi fruit allergy is possibly more significant IMHO as it's something you're not able to prevent, and you do eat alot of pre-prepared food as a pilot...ie you are extremely likely to come across this at some point.
It also depends how 'allergic' you are ie. do you have a full blown anaphylactic reaction, or just tingly swollen lips for a few minutes? A full blown anaphylactic reaction is a medical emergency, and if there was a risk of it happening, it would preclude you from being a pilot (in Australia anyway).
You might want to research desensitisation...the technique's not perfect, but is improving all the time. Needless to say, this all costs $$$$, but it might be a way out.
