Reversing peanut advice prevented tens of thousands of allergy cases, researchers say : NPR

This is a remarkable story. It's peculiar how peanut allergies spiked for around 20 years and became a thing so a researcher started studying what was going on. 

He got the peanut industry to fund the research and then studied children in Israel who had a lower incidence of peanut allergies against children from similar backgrounds who lived in the US. 

And what he found was that children in Israel were given a peanut snack fairly commonly from a very young age, where children in the states were not. 

And after studying further the conclusion was that avoiding peanuts in young children actually increased the likelihood of peanut allergies. 

The recommendation, then, was to introduce peanuts early, and the number of cases we y down. 

Science for the win.
