A familiar drink faces unfamiliar scientific scrutiny.

For more than a century, Coca-Cola has been treated as a cultural constant rather than a health question. That assumption is starting to fracture. Nutrition researchers, endocrinologists, and public health officials are now revisiting evidence long considered settled. Rising chronic disease rates, updated metabolic research, and population scale data have pushed the conversation into uncomfortable territory. The drink itself has not changed much. What has changed is how clearly its biological effects can now be measured across age, income, and geography.
