Thanks this is really interesting, I didn't realise there was a direct genetic link with Type 2, i just thought it was with Type 1. I clearly need to cut down on my sugar (a lot!!!), but seem to be doing the right things aside from that as i eat lots of fibre and veg, plus limited red / processed meat and barely any alcohol due to previously having had colon polyps. I'm nearly 49. It doesn't say how often you need the blood test, I had one done last march in Australia but assume it'd need to be done every year or so, is that right?
