Surely that's a good thing?
No, it's not. Germs are good. Too much cleanliness is bad. Think back to when we were children. We used to make mud pies, splash about in dirty puddles, put all sorts of things into our mouths...
So are you saying we aren't allowing our children's immune systems to develop?
Yes, that's exactly what I'm saying. Our obsessions with cleanliness have gone too far. We need to expose our children to germs so that their defence mechanisms have a chance to develop and get stronger. If they aren't exposed there's a danger that they'll develop allergies and food intolerances later on.
What about genes? Aren't some allergies genetic?
Yes and no. The jury is still out on that one. Allergy problems do run in the family but we don't understand why. Scientists have
identified cases in families where there's been some kind of genetic mutation which affects the immune system in some way. This might result in members of a family being more prone to allergies – but not necessarily the same allergies. So Dad might be allergic to milk products while one child gets hayfever and another develops an allergy to some sort of skin cream.
And this doesn't explain why there has been such an increase in allergies over the past ten years or so.
No. It doesn't. |
