Not to sugar-coat things, but...
In the lecture, he suggests that fruit isn't necessarily bad, because fruit tends to come along with fiber, and fiber slows down the rate at which the sugar hits your blood. This gives your gut microflora a chance to get at it and metabolize it into less harmful compounds (though with the unfortunate but health-neutral side effect of flatulence).
Anyway, this got me wondering. Which sugars are in which fruit? Not all sugars, or fruits, are equal. So, here's a nice chart I made from some data I found somewhere on the internet.
It makes me a little sad to see apples, pears and mangos down there at the bottom, though I'm delighted to see avocados at the top. Also, I would like to remind you that not everything that is quantitative is scientific, and making a nice chart of some data you find on a random web page is certainly not scientific.
