Both my parents were diabetic Type 2 on metformin. They have been dead for over twenty years; but have just learnt they were encouraged to have four slices of bread a day, a large regular helping of mashed or roast pots. I am still laughing. However what is weird when i recently cleared out the garage I found some of their bg testing notes and it all appeared in non diabetic range. Shame I can't ask them what the hell was going on!
