The effects of eating peanut products as a baby to avoid the risk of allergy have been backed up by new research.
In 2015, a study claimed early exposure to peanut products could cut the risk of allergy by 80%.
Now researchers say “long-lasting” allergy protection can be sustained – even when the snacks are later avoided for a year.

There was an absolutely fascinating article in New Scientist about 10 years go (can’t find it now) about how food allergies varied with geography. From what I recall peanut allergies were very rare in Southern European countries, but incidents of apple allergy were really high.
There was another article that found that areas where rates of parasitic infection are highest have the lowest rates of food allergies; and areas with the highest rates of food allergies have the lowest rates of parasitic infection. They hypothesized that parasites’ ability to remain in the body while avoiding being detected by the immune system may be connected to food allergies, and may suggest possible means of treating food allergies.
