I do think that trying to make things easier for yourself by looking for extra foods that 'might' be allowed, is infact a futile exercise, as it actually makes the diet a hundred times more difficult.
It's so simple if you just keep to the black and white rules. No fretting, weighing, measuring, checking portion sizes and label contents necessary.
I've decided that 'tolerated' foods are something that I will look forward to, and enjoy, when I know I am officially allowed them. I know not everyone is the same, but it has made life, and the diet, easier for me.
