Thanx for the info I really appreciate it. Can the small amount of vinegar in the rice cause such bad side effects as I had today like lethargy, nausea, diarrhoea and mind fog? I have experienced this when I ate bread etc but surprised to get such a bad reaction from some vinegar in Sushi. The only other thing I have eaten out of the ordinary was Spirulina powder in a vege juice I made for breakfast.
