I’m a coffee drinker, have been for many many years. I drink 2-3 standard mugs of black coffee a day, across the morning & early afternoon. This has probably been asked many times on here, but do any of you find that coffee (particularly black) affects your blood sugar levels? Or has a negative impact in any way?
The issues is how much sugar or sweetener you take with it.
Black coffee can have a negative impact just not in the way you are thinking. Coffee can inhibit your body's ability to absorb magnesium a lack of magnesium is a common factor in Insulin Resistance in type 2 Diabetics.
You can balance this out by eating couple of squares of Dark Chocolate 80% Cocoa , rich in Magnesium and loaded with antioxidants which are good for the heart too.
