Regular consumption of Coca-Cola negatively affects human health
Substantial scientific literature consistently demonstrates that regular consumption of sugar-sweetened beverages like Coca-Cola negatively affects human health by increasing the risk of obesity, type 2 diabetes, cardiovascular disease, and metabolic disorders.
The claim is specific and falsifiable, passing Step 0 easily. The retrieved evidence includes robust umbrella reviews, meta-analyses, and comprehensive public health studies demonstrating clear adverse health outcomes associated with regular sugar-sweetened beverage intake. None of the papers refute the claim, making the balance firmly supportive.
