The verdict
Diet Pepsi by Pepsi scores 65/100 in PlainFoodSafe's ingredient screening. We compared its 9 labeled ingredients with FDA SAFFA regulatory records and CSPI Chemical Cuisine ratings; 3 ingredients are flagged for caution. This is a focused 9-component label led by Carbonated Water, Caramel Coloring, Aspartame; compare those leading ingredients with the product's processing and nutrition fields before deciding whether it fits your goal. This is not a recall, allergy, medical, or dietary-safety determination.

Screening model notes
How Nutri-Score, NOVA, and list length read this record
This label lands in the third of four positions on the published scale. What separates that position from its neighbours is arithmetic rather than judgement: identical inputs run through the documented weighting always arrive at the same place. Anyone who works the calculation through by hand, using the methodology write-up together with the itemised ratings further down, will reproduce this number exactly — which is the reason for publishing a computed figure instead of an opinion.
Nutri-Score settled on its middle grade here, the band the algorithm produces when the penalty and credit sides of its nutrient ledger come out close to balanced. A mid-scale grade is a statement about the panel as a whole rather than about any single nutrient, and products arrive at it by very different routes: a moderate profile across every term, or high marks on some offset by heavy penalties on others. The grade is computed separately from the ingredient screen below and the two are not comparable measures.
The declared list parsed into a small number of components. On a short list the registry screen covers close to everything the packaging declares, and any single matched component accounts for a correspondingly large share of the composite. Short lists also leave less room for parsing error, since there are fewer separators and qualifiers for the extraction to resolve.

How It Compares to Its Category
Among the 32,623 products we've scored in the Beverages category, the average safety score is 90.5/100. Diet Pepsi scores 25.5 points below that category average (65/100 vs. 90.5/100), so it is a comparatively weaker pick for shoppers screening within that category specifically, rather than against the product catalog as a whole.

Ingredient-list length is a descriptive property of the label, not a safety rating. A longer list is not automatically worse and a shorter one is not automatically better; the count is shown so the label can be placed against a comparable population. The comparison here runs against the 4,874 Beverages and beverages preparations products we publish with a parsed label, not against the whole catalogue, because list length varies far more between categories than within one.
