Oily fish and nuts ‘cut chance of food allergies’

Academics have discovered that omega-3 fatty acids – found in fish like salmon, mackerel and tuna, as well as walnuts, pumpkin seeds and linseeds – prompt the gut to develop in a way that boosts the immune system.
And they warn that more children could now be at risk of food allergies than in the past because consumption of such foods has fallen.

Nonetheless, a recent, robust study from the Isle of Wight found one in 20 children did have an allergy. It also found evidence that the real incidence was growing.

Allergy experts do not really know what is behind the rise. One theory is the ‘hygiene hypothesis’: that as homes have become cleaner, children’s immune systems now have less chance to develop fully.
