How we research, write and review
NourishMark covers decisions where being wrong costs real money or real wellbeing. This page sets out who produces the work, what every article is checked against, and the limits of what we do.
Who is behind the work

Hamza Hai, MBA
Editor, NourishMark
Hamza Hai is the editor of NourishMark. She holds an MBA and reviews the site's articles against our editorial standards, checking that every figure is labelled for what it is, that nothing is presented as verified fact without a source the reader can check, and that the writing stays useful to a non-specialist.

Dr. Shayaan Khan, MBBS
Medical reviewer, NourishMark
Dr. Shayaan Khan is the medical reviewer for NourishMark. He holds an MBBS from MGM Medical College, Navi Mumbai, and is the author of published research including a narrative review of postpartum anxiety and depression in Mental Health Science. He has taught physiology at university level. He reviews the site's health content for medical accuracy: that physiology and mechanisms are described correctly, that no claim is stated more strongly than the evidence behind it, and that anything specific to an individual reader is sent to that reader's own clinician.
Editorial team
Evidence-based health writing
NourishMark guides are written by health writers, attribute published guidance to the body that issues it, and are medically reviewed by Dr. Shayaan Khan, MBBS. They are evidence-based general information, written to be educational, not medical advice.
What every article is checked against
- Nothing is invented. We do not publish statistics, study results, citations, quotes, prices, or credentials that we cannot stand behind. Where a specific number would be a guess, we write the principle instead and say why.
- Every figure is labelled. Illustrative examples are called illustrative. A worked example, its charts, its calculator and its FAQs are checked against each other so the same scenario produces the same numbers everywhere.
- Time-sensitive facts point to the source. Rates, limits, deadlines, programme rules and code requirements change, and they vary by provider and by place. We explain the mechanism and send you to the official source for the current figure.
- Links are verified. Internal links are checked to resolve. We do not link out for the sake of it, and a link is never a substitute for explaining something.
- Images are described from the image. Alt text and captions describe what is actually in the picture. Where a stock image does not match the subject, we say so in the caption rather than let it imply something untrue.
- Corrections are made in place. When something is wrong we fix the article itself and move the updated date, rather than quietly leaving it or burying a note.
The limits of what we do
Two people review this site and each has a different remit. Our editor holds an MBA, not a clinical qualification, and checks articles against our editorial standards: that figures are labelled for what they are, that nothing is presented as verified fact without a source you can check, and that the writing stays useful to a non-specialist. Our medical reviewer holds an MBBS and checks health content for medical accuracy: that physiology and mechanisms are described correctly and that no claim is stated more strongly than the evidence behind it.
Neither review makes this medical advice. Our medical reviewer is not a registered dietitian, does not hold a United States practising licence, and is not your doctor. Nothing on NourishMark is a diagnosis, a treatment plan, or a substitute for care from a qualified health professional who knows your history. Decisions about your health belong with your own clinician, and nothing here should lead you to delay or stop care.
Found something wrong?
Corrections are welcome and we would rather hear it from you than not. Email [email protected] with the page and what is inaccurate, and we will check it against the source and correct the article if it is wrong.
