Verity — the transparency index
The healthiest choices,
ranked by research.
Every entry is scored on the strength of peer-reviewed science — nutritional density, evidence weight, and AURA alignment. Research, curated by Chef Aristide. No paid placements.
How we score
The method behind every number
Evidence strength
Every score reflects the weight of peer-reviewed research — meta-analyses and long-term cohorts over single small studies.
Nutritional density
Quality nutrients per calorie: vitamins, minerals, polyphenols, omega-3, and fiber that earn every bite.
AURA alignment
Mapped to a domain — Fuel, Mind, Core, or Rhythm — and how directly it serves that realm's intent.
Transparency
Curated by Chef Aristide through the scientific literature. This is research, not product testing, and never a paid placement.
Research briefs
What the science says
Research brief
The MIND diet and cognitive ageing
Leafy greens and berries lead the evidence for slowing age-related cognitive decline across multiple cohorts.
Research brief
Beta-glucan and cholesterol
Soluble oat fibre is one of the most-replicated dietary interventions for LDL reduction.
Reference library
The topics behind the scores
Heavy metals
Why their presence in food is expected rather than alarming, and the standards research compares against.
Microplastics
Why particle size governs whether a plastic can cross a biological barrier.
PFAS
Why a targeted panel measures a fraction of the class, and which limits remain in force.
Omega-3 & fatty acids
How composition supports nutritional characterisation and omega-3 goals.
Polyphenols
How the broad class of plant compounds maps to replicable health signals.
Fermentation & the microbiome
What live cultures do, and don't do, after they reach the gut.
