What is Dextrose?
Dextrose is a simple sugar (monosaccharide) derived from corn starch hydrolysis. It is chemically identical to glucose and is the primary energy source for human cells. In food manufacturing, dextrose is used as a sweetener, fermentation substrate, and browning agent. It has a glycemic index of approximately 100.
What is Erythritol?
Erythritol is a four-carbon sugar alcohol naturally occurring in small amounts in fruits, fermented foods, and mushrooms. Commercially produced via fermentation of glucose by yeasts such as Moniliella pollinis, it has approximately 70% of sucrose's sweetness, provides 0.24 kcal/g, and has a glycemic index of 0. It is nearly completely absorbed in the small intestine and excreted unchanged in urine, which explains its unusually low laxative effect compared to other polyols.
Documented risks
Dextrose: Dextrose has a GI of 100 (the standard reference), causing rapid blood glucose elevation. Excessive consumption contributes to caloric overload, dental caries, and metabolic syndrome risk. However, as a single ingredient it is no more concerning than other simple sugars. The health risks of dextrose are those of added sugar generally, which the American Heart Association and WHO link to obesity, type 2 diabetes, and cardiovascular disease when consumed in excess.
Erythritol: A 2023 observational study published in Nature Medicine (Hazen et al., Cleveland Clinic) found that elevated blood erythritol levels were associated with increased risk of major adverse cardiovascular events (MACE), including heart attack and stroke. Additionally, erythritol was found to enhance platelet aggregation in vitro. This study was widely reported and has generated significant scientific debate; critics note that it was observational (not causational), and that the study population had pre-existing cardiovascular risk factors. Regulatory agencies have not changed their approval status. The long-term cardiovascular implications require further research.
