Food allergies, and how we can bio-engineer them away

Not, obviously, with current technology.

Shona is allergic to tomatoes. It took her a long time to work out that she had an allergy, as opposed to something wrong with her digestive system, because you get tomatoes in so many things. When she came up to see us, bringing her progeny with her, and we decided to go to Café Andaluz for lunch, it was decidedly non-trivial to find things that she could eat (onions were out as well, because she was breast-feeding and onions disagree with Jonathan, apparently).

I've met in passing people who have even more strenuous allergies - gluten, for instance, is a right bastard, because it means you effectively can't eat anything baked, or pasta.

On the other hand, we know that Cleodhna is allergic to something, but we don't know if it's lamb, coriander, or something else. It's not something that crops up that often, annoyingly, so even keeping a food diary is unlikely to work.

Eventually we'll find a way of identifying exactly what it is in our genetic makeup that causes food allergies, and zap it. In the mean time, though, the best thing we can do is reduce to a minimum the likelyhood of food being allergic.

Which means that we should find something that nobody is allergic to, and put it in everything.
