Welcome to the forum Don, from a fellow T2.
You've already got a start going from 54 to 47. As far diabetics go, that 54 was relatively low (though still high).
I'd suggest self testing to see what affect food has on your blood glucose (BG) levels, along with any changes you make.
Keep a food diary, along with a record of your levels. Hopefully, after a couple of weeks, you'll start to see a pattern.
It's not food that raises your BG. It's carbohydrates in particular. Potatoes, paster (unfortuneatley since it's so cheap), rice bread etc. What affect these have varies.
