Diet Coke

Coca-Cola · 300 ml can

Diet Coke is a zero-sugar, zero-calorie carbonated soft drink. While it avoids the high sugar load of traditional sodas, its health profile is contentious due to the use of artificial sweeteners, primarily aspartame and acesulfame potassium.

This card is the decision shortcut. The detailed evidence and citations live in the six-axis cards below.

Sugar load

Diet Coke contains no sugar. Instead, it uses artificial sweeteners (Aspartame and Acesulfame Potassium) to provide sweetness without calories, thus avoiding the problems of high free sugar intake.

Processing tier
■ Don't eat trigger

As a carbonated soft drink with no whole ingredients, Diet Coke is a NOVA Group 4 ultra-processed product. Its formulation is based on industrial ingredients and additives like artificial sweeteners and flavours.

Fat / oil type

The product is a carbonated water-based beverage and contains no fats or oils.

Sodium
■ Think twice trigger

Contains 12mg of sodium per 100ml, which translates to 40mg per 330ml can. While not excessively high, it contributes to daily sodium intake from a source with no nutritional benefit.

Marketing deception
■ Think twice trigger

The "Diet" and "Zero Calorie" branding can create a "health halo," implying it's a healthy choice. However, it's an ultra-processed beverage with artificial sweeteners that have been subject to health warnings.

Regulatory history
■ Don't eat trigger

In 2023, the WHO's IARC classified aspartame, a key ingredient, as 'possibly carcinogenic'. [1] Previously, in 2003, it was part of a major controversy in India over alleged pesticide residues found in soft drinks by the Centre for Science and Environment.
