The "cause of death" noted for these cases never mentions metabolic syndrome (variously, fatty liver disease, cirrhosis, processed-food disease), but rather secondary illnesses it drives, most notably high blood pressure, type 2 diabetes, obesity, and circulatory illness. Most of these are products of high uric acid level, itself a byproduct of fructose processing in the liver. Fructose is processed only in the liver, like other toxins, and most similarly to alcohol.
The standard to diagnose high uric acid has risen sharply in recent decades as levels themselves have risen with sugar intake, so people with a deadly uric acid level do not learn of the core problem. They instead are told of the high blood pressure and diabetes, and get medication for that, masking it but not its harms.
We should not be allowing sale of these products; or at least, labels should warn of their fructose content. We could start seeing "contains no fructose!" on packaging, instead of "non-fat". (Because fat, even saturated fat, it now turns out, is harmless.)
(Fructose in normal food, particularly fruit, comes with enough fiber to divert most of the fructose to your gut bacteria. Juice and soda strip away this protection.)
