I am in the midst of a flare up and today at 5pm I tried an Atkins chocolate bar. At 7pm I also had some slow cooked meat that was cooked with mushrooms, although my wife removed the actual mushrooms when she served it up. Now at 8.30pm, I am all bloated (I look 9 months pregnant), farty and will definitely have diarrhoea. Which was more likely the trigger. The chocolate Atkins bar, or the meat cooked in mushrooms all day?
