Dextrose vs Invert Sugar: which is worse?

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 Invert Sugar?

Invert sugar is a mixture of equal parts glucose and fructose produced by the acid or enzymatic hydrolysis of sucrose. It is sweeter than table sugar by about 25% and has enhanced moisture-retaining properties. Bees naturally produce invert sugar in honey through the enzyme invertase.

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.

Invert Sugar: Invert sugar poses the same metabolic risks as other added sugars. The free fructose component is metabolized directly in the liver, and excessive fructose consumption has been linked to non-alcoholic fatty liver disease, increased triglycerides, and insulin resistance, as documented in multiple reviews including a 2013 paper in Current Opinion in Lipidology. At moderate consumption, it is not specifically more harmful than sucrose. Regulatory agencies worldwide permit its use without restriction.
