About
Editorial policy
You deserve diet information that's honest about what it knows and what it doesn't. These are the rules every page follows.
What we publish
Guides to help you understand and compare ways of eating. We don't prescribe diets, diagnose anything, or try to scare you into a decision. If a page wouldn't help you decide or do something, we don't publish it.
Where the facts come from
We rely on public health bodies and research summaries: the NHS, the US National Institutes of Health, the CDC, the World Health Organization, Harvard's Nutrition Source, Mayo Clinic and peer-reviewed studies. We link to our sources so you can check them. We don't use diet company marketing, and we don't invent statistics or success stories.
How we handle uncertainty
Nutrition research is messy. Many studies are short, small or based on what people remember eating. When the evidence is mixed, we say so rather than pick the most exciting result.
Money and independence
No diet company, app or supplement maker pays to be featured or to shape what we write. If we ever earn money from a link or an advert, we'll label it clearly, and it won't change our conclusions.
Mistakes
If something is wrong or out of date, email hello@onlinediets.com. We fix real errors quickly and update the date on the page.
Who's responsible
Greg Parsons, the founder, is responsible for these standards. See how content is reviewed for what that does and doesn't include.
