Verdict: unhealthy

Pepsi Zero Sugar receives an unhealthy score of 35/100 primarily due to its heavy reliance on artificial sweeteners and acidic additives that offer zero nutritional value.

Key takeaways

  • Zero grams of sugar or calories per serving.
  • Contains artificial sweeteners aspartame and acesulfame potassium.
  • Phosphoric acid addition may impact bone density over time.
  • High environmental footprint due to aluminum packaging.
  • Provides zero nutritional value or essential vitamins.

Our read on this product

With a health score of 35/100, Pepsi Zero Sugar is essentially a mixture of water, additives, and synthetics rather than a source of nourishment. The inclusion of phosphoric acid poses concerns for long-term bone health, while the combination of aspartame and acesulfame potassium provides sweetness without any caloric density. While the zero-calorie count is appealing, the presence of these synthetic compounds keeps the overall wellness rating low. Consumers should prioritize whole-food hydration sources over these laboratory-derived flavor profiles.

Best for

This beverage is intended for occasional consumption by healthy adults looking to eliminate liquid sugar from their diet without giving up carbonated soda.

Approach with care

Individuals with phenylketonuria must avoid this due to aspartame, and those with sensitive stomachs or bone health concerns should limit their intake.
