I know the statistics point to sugar as being evil incarnate, but I feel there's more wrong with the American cuisine and now sugar gets the blame for all of it.
Personally I eat around 5 teaspoons of sugar a day, mostly in the form of marmalade and ketchup and don't seam to have any adverse effects. Also I guess you'd have to drink sweetened beverages to get to 17 teaspoons, cause at 10 teaspoons a day all my food would be unbearably sweet.
I do agree that sugar is taking the blame for the companies selling us these sugary treats. I mean its literally JUST yummy carbs, it’s not like its a carcinogen. And the average person has been so completely numbed by a life of excess sugar that it makes the already predatory food companies push even more sugar in to compete.
Since then I've been cutting the sugar in every recipe down to 1/3 to 1/4 of what's specified. You just plain don't need it: at least provided you've largely dropped sugar out of your regular diet (so very limited off the shelf food - which now tastes incredibly sweet to me these days).
