Glucose-fructose syrup - a popular sugar substitute endangering our wellbeing!

High-fructose glucose syrup constitutes a ubiquitous additive across an extensive spectrum of food products, including—but not limited to—chocolate confections, granola bars, cultured dairy products such as yogurt, sugary sweets, breakfast cereals, carbonated soft drinks, fruit-based beverages, and a multitude of other processed comestibles. In the vast majority of instances, it functions as a direct substitute for conventional table sugar in sweetened formulations. Nevertheless, it is not uncommon for product labels to list both sucrose and the aforementioned syrup concurrently among the ingredients. The widespread adoption of this component is likely attributable to its cost-effectiveness, as it is markedly less expensive than crystalline sugar, thereby rendering it an appealing choice for food manufacturers. From a physical standpoint, it presents as a clear or pale yellow liquid, conferring a distinct operational advantage by obviating the necessity for prior dissolution—a requirement inherent to granular sugar. Further advantages encompass an extended shelf life relative to sugar, reduced viscosity, resistance to crystallization, the capacity to mitigate desiccation in finished goods, and microbiological stability, which effectively suppresses the proliferation of undesirable microorganisms. Chemically, the distinction between sucrose (table sugar) and high-fructose glucose syrup lies in their compositional ratios: sucrose comprises equal parts glucose and fructose (a 1:1 ratio), whereas the syrup contains 55% fructose and 42% glucose. While both sweeteners exhibit comparable sweetness intensity and caloric density, the ongoing debates regarding the syrup’s potential adverse health effects stem from the divergent metabolic pathways of fructose as opposed to glucose within the human body.

When we don't see the names of the carbohydrates we know, like sucrose, fructose, or glucose, we recognize this product as free of additives in the form of sugar. However, often called corn syrup, our sugar syrup is glucose-free, which is artificially enriched in many products, and we do not even know about it. This way our body increases the unnecessary amount of sugar in our blood, which in turn reduces the amount of energy that is harmful to our body's health by increasing our sugar intake.
