We all have differencet tolerances and requirements, so you need to find what
your body will accept rather than be ruled absolutetly by other opnions - including mine!
Use your meter to test and try to keep within your chosen or recommended daily carbs allowances
I've never bothered with GI data at all. but essentially just avoid fruit with high sugary carb content. Bananas (which before diabetes were my main go-to source for potassium), other high carb fresh fruit, dried fruit, or sweetened tinned fuit, are what I definitely choose to keep off-limits now. But in addition the usual recommended limited selection of berries, I eat a somewhat wider variety of mainly in-season fruit - including rhubarb, gooseberries, black and red currants, for example....
However, I still aim to keep to lower carb options, and/or have smaller portions to help keep my glucose levels down, and I definitely use my meter as a guide.
