I make my own Oat soda bread. 500g pot Natural Yoghurt, 1 egg, 2 tsp bicarbonate of soda and oats (fill the Yoghurt pot twice with any oats or porridge). mix together and put in a loaf tin in a preheated oven 180c for 50 min, remove from tin and return for a further 10 min. You can exchange some volume of oats with oat germ / pinhead oatmeal / wholemeal flour and add seeds. It freezes well and is very similar to Irish Soda bread. Great with savory or sweet... keeps for about 5 days in the bread tin without going mouldy. Not sure the precise effect on the bloods but I have lost 10kg in weight since being diagnosed T2 in June by removing cereal and white bread from my diet. HBAC1 levels in normal range now... As there is no yeast breaking down the carbs to sugars - the more unprocessed the oats the lower the sugar content...
