Just to add to the body of anecdotal evidence - and in case this helps anybody else, cutting out gluten has cured my Menieres more or less 100% - I've been left with some residual hearing loss, and minor tinitus, but no more attacks. I've had Menieres on and off for about 15 years - with attacks about once a month or so and sometimes severely unpleasant and debilitating. A couple of years ago, I wanted to lose a bit of weight and went on the keto (zero carb) diet for 6 months. I was amazed to discover that after a month or so, the Menieres cleared up completely. After the 6 months were up, having lost a fair bit of weight, I started eating 'normally' again. The Meniers came back with a vengence. So obviously it was something that I had been previously cutting out that was triggering it, and thats when I went gluten free whilst continuing with other carbs. That was it - Menieres gone, and for me, definitely gluten. I dont even have to cut it out completely, I seem to be able to have the occasional 'treat' without adverse effect - I just keep it very low. The thing that makes it so damned hard to pin down is that there is a substantial delay between eating excess gluten and the menieres symptoms - 3 or 4 weeks or so. Anyway - something to try if you're suffering. I hope it works for others too, and also hope that there will be some research into the link - as doctors dont generally believe there is any link at all.
