There is a well-known trope about British people having the runs after a night eating curry. One of the reasons for this, at least for some, is salicylate sensitivity – a heritable food intolerance that many people know nothing about, though it is estimated to affect perhaps around 2.5% of Europeans. An allergy specialist I saw years ago described the phenomenon as “edge of the world syndrome”, she told me that on some days every person in her waiting room with food sensitivities was red-haired, and explained that many people with northern European ancestry are today eating a diet that is utterly alien to that of their ancestors. Basically, northern Europeans adapted to eating a diet that was, for the most part, naturally low in salicylates. In so doing some of them lost the ability to efficiently metabolise the higher amounts of salicylates naturally found in the skin of most fruit, herbs and spices (as well as many vegetables) found further south on the globe – foods that are becoming increasingly common in modern Western diets. Today, many people put up with the symptoms of salicylate sensitivity because the symptoms are either mild enough to ignore or because they don’t understand the root cause of troubling health issues.
