I has issues about 2 months ago where my only carb source was a half a box of minute rice to a box of minute ice per day.
I thought it was sulfites causing my sore throat. I stopped eating the rice and the next day my throat was better
It took about 2 weeks of me eating it till it became a huge problem where I couldnt swallow
It was the only thing that was new in the diet and it was an excessive amount
