You shouldn't need a PhD
to get nutrition answers you trust.
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.
Everything exhausting about nutrition research — we handle it.
We curate and vet the evidence
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.
We keep up with the latest research
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.
We balance the science
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.
Test your knowledge
and actually remember what matters
Quizzes built from the same evidence, so what you've learned actually sticks.
Where the evidence comes from
Names you'd recognize
from a doctor's office.
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.
What the latest
research says.
Fresh digests of newly curated research — from the same growing library that answers your questions.
When Healthy Habits Surprise You
This digest is full of findings that cut against conventional wisdom: omega-3 supplements linked to faster cognitive decline, eating less tied to higher cardiac risk, and high levels of a supposedly beneficial gut bacterium predicting worse weight-loss outcomes after bariatric surgery. Across seven research areas — from colorectal cancer detection to acne microbiology to the metabolic effects of dairy sugar — the common thread is that more of a good thing often isn't better, and that the underlying biology is rarely as simple as popular advice suggests. For anyone tracking nutrition for longevity or disease prevention, these studies are a reminder to stay close to the evidence rather than the headlines.
Brain Health & Cognitive Aging
25pFocuses on the intersection of nutrition, lifestyle, and neurological health. Covers research on cognitive decline, Alzheimer's disease, depression, sleep quality, and the impact of diet on brain network connectivity.
Cancer & Oncology Nutrition
19pExamines the relationship between diet, nutritional status, and cancer outcomes. Includes studies on cancer risk factors, cachexia, sarcopenia, and the role of the microbiome and supplements in oncology care.
Cardiometabolic Health & Diabetes
48pExplores the latest research on cardiovascular disease, type 2 diabetes, and metabolic syndrome. Key themes include the effects of GLP-1 agonists, lipid management, and the impact of lifestyle interventions on cardiometabolic risk factors.
Environmental & Agricultural Science
36pExplores the intersection of environment, agriculture, and nutrition. Topics include soil microbiomes, heavy metal contamination, sustainable food systems, and the impact of climate change on agricultural yields.
Answers about the answers.
Where do AllNutrition's answers come from?
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.
How up to date is the research?
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.
What is an evidence panorama?
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.
Is AllNutrition free?
Yes. Asking questions, exploring the evidence behind every answer, and the research digest are all free.
Is this medical advice?
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.
