Question 1

Are the writers on this site doctors?

Accepted Answer

No. Nobody on this desk holds a medical qualification — not a doctor, not a dietitian, not a nurse — and every guide says so in the footer and in the editor biography attached to it. We do not run studies and we do not measure anything ourselves. What we do is read the guideline, the database or the paper, write down what it actually says rather than what it is usually reported to say, and mark clearly where a question stops being answerable by an article. On a health site, stating that plainly is worth more than a credential we would have to invent.

Question 2

What does the evidence grade on each guide mean?

Accepted Answer

It describes how strong the evidence behind the guide’s central claim is, in four bands. Strong means multiple consistent human trials or a major guideline built on them. Moderate means the direction is reasonably well supported but the size of the effect is uncertain. Limited means the mechanism is plausible and the human evidence is thin, small or mixed. Contested means credible researchers currently disagree. The grade applies to the central claim, not to every sentence, and a guide graded limited is not a guide we think is useless — it is one we are telling you not to lean on hard.

Question 3

Where do the reference ranges and figures come from?

Accepted Answer

Each guide lists its sources at the bottom, with the specific claim each source supports rather than a decorative link list. We prefer primary and institutional sources — published clinical guidelines, USDA FoodData Central, NIH fact sheets, national health services — over secondary health-content sites. Where a reference range depends on the assay or the population it was derived from, we say so in the range table itself, because a number printed without that context is the main reason people misread their own results.

Question 4

What will you not publish?

Accepted Answer

Four things. We do not publish statistics we cannot attribute — no invented sample sizes, cohorts, odds ratios or survey results. We do not publish a negative claim about a product or an intervention from silence; if a source does not address something, we say nothing rather than inferring absence. We do not publish dosing or treatment instructions, because that is the clinician boundary this desk exists to mark rather than cross. And we do not publish a guide that cannot honestly fill in the evidence grade and the point at which to see someone, which is why some obvious topics are missing.

Question 5

Do you take money from the products you mention?

Accepted Answer

There are no affiliate links on this site and no paid placements. Exactly one guide across the whole site reviews commercial products, and it discloses on the page how it was assembled and which figures came from the companies themselves rather than from an independent party. If that ever changes, it will be disclosed on the page before it is disclosed anywhere else.

Grade	Means	How to read it
Strong	Multiple consistent human trials, or a major guideline built on them	Act on it
Moderate	Direction well supported, size of the effect uncertain	Reasonable to act on
Limited	Plausible mechanism, thin or mixed human evidence	Do not lean on it hard
Contested	Credible researchers currently disagree	Know that the debate exists
