The other day I was behind a woman in the queue at a pharmacy here in France. She had oral thrush. The pharmacist took quite a while talking to her about her treatment and the various medications she'd been given by the doctor then went into the general advice section of the lecture. The most important thing was not to eat, "Trop salé." (Too salty.)
I thought, "Pardon?" Surely it's the other way around, nothing too sugary and yeasty? It bothered me so I googled and sure enough at least in the English results - sugary and yeasty were to be avoided.
This happens all the time. I've heard an awful lot of strange medical advice in France over the years and the folk remedies of my Russian ex boyfriend for various illnesses were quite bizarre too. Putting your head over the boiling potato water to cure a cold because the vitamin c evaporated into the steam was a good one.
Have you ever been given strange medical advice abroad?
This thread is kind of inspired by the post about the Germans opening their windows all the time for "Luften"
On the other hand, if you're not a Brit, what are our bizarre medical beliefs/practices?
