Dont know why exactly but Ive found that eating the cheaper basic brands of porridge (different names in different supermarkets) doesnt appear to make my bg levels go up high at all. I just use about 3 heaped small dsp in a bowl with some boiling water to just about cover it, wait for 10mins for the water to be absorbed and then add 1 dsp of thickish creamy yogurt, stir it all up and sit down and enjoy. Sometimes I use 2dsp of porridge with 2dsp of ground up almonds and that also is very nice and doesnt really cause any bad spike. Could be the porridge and the smaller flakes..... who knows, Be interesting to see if others get the same effect.
