I was explaining this to my daughter in quite simplified terms the other day- we evolved to taste sugar and enjoy it because finding a sweet edible plant meant we had a source of energy to help us hunt that day. Pretty useful if you're a hunter-gatherer.
So we seek out sugar. Now we can get it whenever we want it, in much more massive quantities than we are supposed to be processing. Most of us are addicted. I'm not an exception.
Most added sugars are going to be HFCS these days. But also, that's under the assumption of added sugars, which the image doesn't make any specifications about; a lot of ingredients used in pasta sauces, for example, are going to have natural sugars already.
I just take issue with the misleading image, which would have you believe that a cup of Yoplait is 45% sugar, even though you can read the label and do the math, yourself. Don't get me wrong, it's still a lot of sugar, but not "nearly half the product" levels.
Also 45%? Are we looking at the same image? If you dumped those shot glasses of sugar into those yogurt cups empty, the cups would still be close to empty, not half full...
Sugar is sugar, there's a lot of marketing trying to make it sound like it's not true. There is no good sugar, there is only less bad sugar. High fructose corn syrup is probably the worst, but honey is just liquid sugar.
