OK, I don't know if this is significant, but I decided to experiment with some starch- I haven't touched any since diagnosis, but today I had sushi- so raw fish and rice. I had 10 pieces- the normal amount I would have eaten before diagnosis, and my blood glucose measurement journal is as follows.
7:30am, fasting blood glucose 4.2 (I'm usually in the 3.3 to 3.9 range, but I had some walnuts and sunflower seeds at night as I have been advised my numbers tend to run a little bit too low)
I then had one whole boiled egg and one leftover boiled egg yolk and six walnut halves for breakfast. Later I had a small amount of sunflower seeds for a snack. I had quite a lot of black chinese tea over the course of the morning.
At about 1:30pm I did a test- it was 4.2, exactly the same as my fasting. I then went for sushi and had 10 pieces. Meal was about 1:45 to 2:00.
At 4:00pm I did another test, and it was7.3.
I'm not going to push my luck, carb-wise, but is that last reading significant? To my best understanding, lower than 7.8 should be the sort of reading a non-diabetic would have, with diabetes being greater than 11, and pre-diabetes being the range in between.
