Final answer:
HFCS is linked to obesity and metabolic changes, its prevalence in processed foods contributes to overconsumption, and it indirectly inflates healthcare costs due to diet-related chronic diseases.
Step-by-step explanation:
Three issues with High-Fructose Corn Syrup (HFCS) include its potential to contribute to obesity, its overconsumption due to its prevalence in processed foods, and the potential economic impact on healthcare costs due to diet-related chronic health issues.
Firstly, scientists have suggested that HFCS might alter human metabolism and could play a role in the worldwide obesity crisis. Since HFCS became the primary sweetener, the prevalence of obesity-related health issues has increased in the U.S. and other regions.
Secondly, the ubiquity of HFCS in cheap, processed foods leads to its overconsumption. This contributes to diets high in sugars and fats but low in essential nutrients, possibly exacerbating health problems over time.
Lastly, such unhealthy diets, often reliant on HFCS, typically lead to a rise in chronic health issues, which increase government-subsidized healthcare costs for society, adding an additional external cost to the economy.
