Neither sugar nor HFCS are independently unhealthy. Such evidence does not exist. In the absence of weight gain, refined sugar has no negative effects, except in that it can promote tooth decay if you lack proper oral hygiene, which is however true for a large number of foods.
The new sugar scare is pretty emblematic of why Americans in particular are incredibly stupid on top of being fat idiotic fucks. For good health virtually everybody in the Western world needs to reduce their intake of saturated fat, cholesterol, salt and animal products. Sugar is a distraction from this simple fact. A distraction that appeals to obese American morons who who can't put down the fucking cheeseburgers and donuts. The sugar scare is actively being promoted by the meat and dairy industry and their shills.
The great majority of nutritional science organizations and experts bodies don't even suggest an upper limit for sugar intake because there is no evidence whatsoever that any particular amount of sugar is unhealthy as long as you stay at a healthy weight. By contrast, eating more than 15 grams of saturated fat or 5 grams of table salt a day is most certainly unhealthy even if you run a marathon or 2 a week and have a normal weight.

This laughable garbage study has already been debunked.

And neither glucose nor fructose "increase fat". Only excess calories lead to weight gain, and in anybody on any halfway normal diet, only dietary fat is ever stored as fat.
