Who writes here
Sarah Mitchell writes and signs every article. She is not a doctor, nurse or dietitian, and no medical professional reviews the articles before they go live. We tell you this up front so you can weigh what you read.
Sources we accept
- Government and public health agencies: the CDC, NIDDK and other NIH institutes, the NIH Office of Dietary Supplements, NCCIH and the FDA.
- Professional organizations: the American Diabetes Association, including its Standards of Care.
- Peer-reviewed studies found on PubMed or PubMed Central. Whenever we can, we link straight to the study instead of a news story about it.
- What we avoid: seller pages used as proof of results, anonymous testimonials, and blogs that don’t cite their sources.
You can see every source used on this site on the Sources page.
How we handle numbers
A1C, fasting glucose and other cutoffs come from the ADA and CDC pages we link to. When a study looked at people with type 2 diabetes instead of prediabetes, we say so.
How we use AI
We use AI tools to help with outlines, first drafts, organizing notes and catching typos. Sarah decides what goes into each article, checks every source link and every number against the original source, and signs the final text. AI does not check anything for medical accuracy, and we never present it as a reviewer.
Corrections
When we find an error, we fix it and update the “Last updated” date on the page. If the error changed the meaning of the advice, we also add a short note at the end of the article that says what changed and when.
Affiliate links
Some pages link to a product we recommend, and we may earn a commission if you buy. The commission does not change what we write or the score we give. Read our affiliate disclosure and how we review products.
Medical advice
Nothing on this site replaces your doctor. Read the medical disclaimer.
