Firstly, everyone's response to foods is different. The only way to know how beans affect you is to monitor your sugars.
As for the "Of which sugars" - I ignore it, I ALWAYS count the full carbs and dose according to that.
[The only time the "Of which sugars" may be of use, is if you figure out your response to the different types of carbs, a higher "of which sugars" may make your BG go higher quicker than a low one - but you would need to figure that out by testing. Take home message, everyone is different, test test test!]
