Out of the blue his brother-in-law called to chat (a once yearly thing) and in the course of the conversation he mentioned how salt effects blood sugar.
After the call I googled and found this interesting article. Hope it helps someone else.
Oh, the difference in last weeks readings and this?? The pot of beans I made this week has a big slice of ham. Last weeks had none. This week you do not even need to salt them to eat but hubby ALWAYS salts everything. My fault.
At least we know and can correct it. Big learning curve here.
