Coca-Cola Original Taste

Water with dissolved CO2. Carbonation itself is not a health concern, but as the delivery vehicle for the rest of the formula it doesn't offset any of the harms below.

Industrial sweetener providing all 39 g of added sugar per 12 oz can — well above the WHO-recommended daily limit (25 g) in a single serving. HFCS is metabolically processed predominantly in the liver, drives non-alcoholic fatty liver disease, insulin resistance, and visceral fat accumulation. Sugary-drink consumption is causally linked to type 2 diabetes (Malik et al. 2010 meta-analysis), cardiovascular disease, and dental caries. Almost certainly sourced from glyphosate-sprayed GMO corn.

Ammonia-sulfite process caramel coloring containing 4-methylimidazole (4-MEI), classified by California Proposition 65 as a known carcinogen and listed by IARC as Group 2B (possibly carcinogenic to humans). The Center for Science in the Public Interest petitioned the FDA to ban it; Coca-Cola voluntarily reduced 4-MEI levels in California to dodge warning labels but did not reformulate nationally.
