But we are not talking about product weight - we are talking about caloric value. Yes, you will have to eat an awful lot of celery to get to 3,500 calories. And I think celery is actually a negative because you burn more calories chewing and digesting it than you consume. So that's not a good comparison, unless you just sit around eating celery all day, which creates its own health problems.
3,500 calories is 3,500 calories, no matter where it comes from.
The difference isn't with the number of calories in HFCS, it's how it is metabolized.
High-fructose corn syrup and sucrose are both compounds that contain the simple sugars fructose and glucose, but there are at least two clear differences between them. First, sucrose is composed of equal amounts of the two simple sugars -- it is 50% fructose and 50% glucose -- but the typical high-fructose corn syrup used in this study features a slightly imbalanced ratio, containing 55% fructose and 42% glucose. Larger sugar molecules called higher saccharides make up the remaining 3% of the sweetener. Second, as a result of the manufacturing process for high-fructose corn syrup, the fructose molecules in the sweetener are free and unbound, ready for absorption and utilization. In contrast, every fructose molecule in sucrose that comes from cane sugar or beet sugar is bound to a corresponding glucose molecule and must go through an extra metabolic step before it can be utilized. In the 40 years since the introduction of high-fructose corn syrup as a cost-effective sweetener in the American diet, rates of obesity in the US have skyrocketed, according to the Centers for Disease Control and Prevention. In 1970, around 15% of the US population met the definition for obesity; today, roughly one-third of the American adults are considered obese.
