Nutrition & positives — how we score

The Nutrition & positives category is how NordicScan's method surfaces the good an ingredient brings — vitamins, minerals, fibre, protein, bioactives, and credible dietary positives — so a genuinely better product is rewarded, not just penalised. It is one of the nine evidence categories behind a product's concern score, and it is the category where positive evidence lives. This page explains what the category looks at, the sources behind it, and what the score does and does not claim.

A flag in this category means an ingredient our method associates with a nutritional positive is present — for your research. It is not a health claim, not a statement that a product is good for you, and not medical advice.

What this category looks at

• Food (ingestion). Vitamins, minerals, dietary fibre, protein, and bioactive ingredients, along with the dietary‑pattern correlations reported for them.
• Cosmetic. Skin, hair, and barrier actives (for example niacinamide and panthenol) — assessed on their own dermal evidence and named as the outcome each is associated with in the dermatology literature, not by borrowing food logic.

Positives are first‑class. Credible positive evidence moves the score the same way a concern does — the method does not relegate "good" to an afterthought. But a positive must be earned: it is gated by a dose / legal‑form plausibility check, so a trace or ornamental amount ("a dusting of turmeric", an undeclared culture, a cosmetic active with no meaningful concentration) earns nothing. And a positive can never wash out an unresolved severe concern — a benefit sits alongside a hazard, it does not cancel it.

The evidence and sources we weight

Per the source hierarchy, this category weights inter‑governmental and regulator nutrient references and the peer‑reviewed nutrition and dermatology literature. Each ingredient‑level positive cites the specific source behind it, on the same evidence‑and‑sourcing basis as a concern.

The words we use

Every statement is matched to its evidence tier:

• A composition fact is a nutrition signal — "contains / is a source of / provides [nutrient]", stated factually.
• A research‑backed benefit is a correlation — "associated with [outcome] in [study type]", named as an association, never as causation.
• Where there is a genuine dose‑response relationship, a benefit may be a dose / duration signal — "may contribute to [outcome] at [dose] over [duration]", with the dose and duration in the same sentence, and only for a real dose‑response effect (never a plain correlation relabelled).

We make no disease or medical claim of any kind.

What the score does — and does not — claim

• It does surface credible nutritional and functional positives, with sources, so you can research them.
• It does not claim a product is good for your health, make a medical claim, or present a product as a substitute for a balanced diet.
• A positive is context for your research and a fair reward for a better formulation — not a health endorsement.
