Sugar labelling - which measurement method is most meaningful to you?

I look for sugar per 100grams but I like the spoon picture idea as it would be quicker and easier to see as an additional label.
As for color coding natural and added sugar it may help but I read that sugar is converted to fat regardless if it’s fructose or glucose etc. Often it’s the fiber that slows the bodies sugar absorption, so for me the G.I. rating is important. Is GI the best way to indicate how much sugar will be quickly absorbed in a less healthy manner? Perhaps a fiber to sugars ratio indication could be helpful.
