There is NO evidence that exchanging high fructose corn syrup sweetened cola for cane sugar sweetened cola will have ANY impact on human

what it claims

Replacing high-fructose corn syrup (HFCS) with cane sugar in sodas has no beneficial impact on human health.

holds up

The central point here rests on the biochemistry of metabolism: once ingested, HFCS and cane sugar (sucrose) are broken down into nearly identical amounts of glucose and fructose.

noli's read

The central point here rests on the biochemistry of metabolism: once ingested, HFCS and cane sugar (sucrose) are broken down into nearly identical amounts of glucose and fructose. According to a systematic review published in the American Journal of Clinical Nutrition (a meta-analysis of intervention studies), there is no significant metabolic difference between the two sugars in terms of glycemic or insulin response at equal doses. Current science supports the idea that it is the excess of added sugars, regardless of their source, that poses a problem for metabolic health, rather than the specific distinction between these two sweetening agents. The potential exaggeration lies in the popular perception that demonizes HFCS as being intrinsically more toxic, whereas the evidence does not support this hierarchy. Therefore, there is no solid evidence demonstrating that a simple swap of cane sugar for HFCS would improve health markers. Layne Norton's argument thus aligns with the current scientific consensus on the metabolic equivalence of these two types of sugars.

What the graded evidence says

Linked to, not proven to cause.

Effect
cardiovascular mortality by added-sugar share of calories; sugar-addiction human evidence — adjusted HR ~2.75 (95% CI 1.40-5.42) for CVD mortality at >=25% vs <10% of calories from added sugar (cohort); little human evidence for sugar as an addictive substance
Measured on
general adults; US cohort for mortality

What’s uncertain

The mortality figures come from observational cohorts (association, not proof), and they're driven largely by sugary drinks and total intake. Framing sugar as an addictive drug isn't backed in humans and can fuel unhelpful all-or-nothing thinking.
