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.
Where the evidence comes from
Peer-reviewed journals
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 is full of findings that upend conventional assumptions: a diabetes drug lengthens telomeres, obesity turns out to be protective against one cancer treatment, and a man eating enough calories to sustain significant weight somehow developed scurvy. Running through nearly every topic is a theme of hidden nutritional gaps and unexpected connections — from the gut microbiome slashing liver-complication risk by 71%, to a father's cavity history predicting his child's dental health. Together, these studies push toward a more nuanced picture of how nutrition, metabolism, and everyday medical choices interact across a lifetime.
Research on interventions, biomarkers, and lifestyle factors that influence lifespan, cognitive decline, and muscle preservation in older adults.
Studies examining the relationship between diet, metabolic health, body composition, and cancer risk or treatment outcomes.
Research focusing on heart disease, vascular health, hypertension, and the intersection of cardiovascular and metabolic syndromes.
Clinical and observational research on insulin resistance, type 1 and type 2 diabetes, obesity interventions, and metabolic dysfunction.
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.
