>Instead, eating peanut while the immune system is still developing - and learning to recognise friend from foe - can reduce allergic reactions, experts say.

>Other studies have suggested introducing other foods linked to allergies - such as egg, milk and wheat - early also reduced allergy.

I admit I haven't looked at studies, but this made such intuitive sense to us that we've been first giving both our sons very small samples, then feeding them absolutely every kind of food (that's safe, e.g. not raw honey, and non-junky, e.g. no soda pop) we eat, as early as possible. If for no other reason, then to find out if they do have an allergy. Anecdata ≠ data, but both of them have zero allergies as far as we know, 6 and 2 years old now. Obviously, the nutritional needs of children and adults are different, so they consume different amounts of each kind of food than we do.
