We read the research and vet every source, then turn it into clear, actionable answers — on longevity, everyday risks, what's actually worth eating, and what to avoid.
Tens of thousands of curated studies, with new research added every week — the same question earns a fuller answer over time. Free, forever.

so you don't have to
Tens of thousands of peer-reviewed studies, plus the most reputable clinical guidelines from bodies like the AAP, WHO, and CDC — each scored for authority, funding independence, and bias before it reaches you. Not blogs, not influencers.
so your answers never go stale
New curated research lands in the library every week. Ask the same question next month and the answer reflects what the evidence says then — not a decade-old study that's been revised or retracted.
so you're not stuck with one source
Consensus aggregated across dozens of independent sources — where experts agree, where they disagree, and what it means for your real-world risk.
and actually remember what matters
Quizzes built from the same evidence, so what you've learned actually sticks.

The most reputable guidelines
…and dozens more — every source conflict-of-interest checked, trust-scored, and the library refreshed weekly as new research is published.
Fresh digests of newly curated research — from the same growing library that answers your questions.
This digest delivers a wave of counterintuitive findings — from polyphenols that raise LDL yet improve its quality, to semaglutide users who stop feeling hungry but keep cutting calories, to two or three eggs a day potentially slashing dementia risk by nearly a third. Across seven topic areas, the research challenges simple narratives: ultra-processed foods are linked to millions of deaths globally, gut bacteria transplants show early promise for depression, and housing policy turns out to shape children's metabolic health in measurable ways. Together, these studies make a compelling case that the relationships between diet, environment, and long-term health are far more nuanced — and more actionable — than any single headline suggests.
Studies exploring the impact of nutrition on cognitive decline, muscle preservation, and healthy aging.
Investigations into ultra-processed foods, sustainable diets, food equity, and population-level nutrition strategies.
A catch-all collection of studies covering micronutrients, cancer, kidney disease, supplements, and environmental science.
Research on how gut bacteria, probiotics, and the gut-brain axis influence digestion, immunity, and overall health.
Every answer is built from a curated library of tens of thousands of peer-reviewed studies, plus the most reputable clinical guidelines from organizations like the WHO, CDC, and American Academy of Pediatrics. Each source is checked for conflicts of interest and given a trust score, and every answer cites the exact sources it used.
Newly published research is curated into the library every week. That means answers improve over time — ask the same question a month from now and it reflects the newest evidence, not a stale snapshot.
A panorama is a big-picture report that reads every relevant paper in the library on your question, weighs each by trust, and shows where the evidence points — from longevity habits to everyday risks — with every claim traceable to its sources. Because the library keeps growing, re-running a panorama later shows how the picture evolves.
Yes. Asking questions, exploring the evidence behind every answer, and the research digest are all free.
No. AllNutrition summarizes what published research and clinical guidelines say, with citations so you can verify everything yourself. For decisions about your health, talk with your clinician — and bring the sources with you.
