How we work

Editorial standards

NourishFix publishes nutrition guides and a meal planner for adults living with type 2 diabetes, high blood pressure, PMOS, weight concerns and metabolic syndrome. This page explains who writes our content, which evidence we use, how we keep it current, and how to tell us when we get something wrong.

Last updated: October 12, 2026

At a glance

Written by a dietitian

Every guide and the meal planner are written or reviewed by a registered dietitian nutritionist.

Strongest evidence first

Clinical guidelines and reviews of trials come first. Every guide lists its references.

Kept current

Guides and planner sources are reviewed at least once a year, and sooner when a major guideline changes.

Independent

No sponsored content, paid placements or affiliate deals that influence what we write.

Who writes and reviews our content

Every article and every part of the meal planner is written or reviewed by Shiundu Valerie, RDN, a registered dietitian nutritionist and the founder of NourishFix. Meet our dietitian.

Each article shows the author’s name.

The evidence we use

We base our content on the strongest evidence available, roughly in this order:

  1. Clinical practice guidelines from recognized bodies, such as the American Diabetes Association’s Standards of Care, the Dietary Guidelines for Americans and the international evidence-based guideline for PMOS (published as the PCOS guideline).
  2. Systematic reviews and meta-analyses of randomized controlled trials.
  3. Individual randomized controlled trials.
  4. Large observational studies, which we describe as showing a link, not proof that one thing causes another.

We don’t base advice on single small studies, animal or cell studies, press releases or product marketing. When the evidence is mixed or limited, we say so.

Every article ends with a reference list, with links or DOIs, so you can read the original research yourself.

How we write

  • Plain language. We explain the why behind each recommendation, so you can decide how it fits your life.
  • Food, not promises. We describe foods and what the research found. We don’t promise health outcomes. Where we give numbers from studies, they are averages, and individual results vary.
  • No restrictive diets. We don’t shame foods or push extreme plans. We help you fit evidence-based eating around your budget, schedule and food preferences.
  • Medication safety. When a change in diet could affect a medicine, such as insulin, some diabetes tablets or blood pressure medicines, we say to talk to your care team first.
  • Current names. We use PMOS (polyendocrine metabolic ovarian syndrome), the name agreed in 2026 for the condition formerly called PCOS. Published titles keep their original wording.

Keeping content up to date

We review each article at least once a year, and sooner when a major guideline changes, for example when the American Diabetes Association publishes its yearly Standards of Care each January. Each article shows the date it was last updated.

Our meal planner

  • Every nutrition target in the planner names the guideline it comes from and the date we last checked it. The full list is on our planner sources page. We re-check each source at least once a year.
  • Nutrient values come from USDA FoodData Central. For people in the UK and Australia, values for some prepared foods come from the UK’s Composition of Foods Integrated Dataset (CoFID) and the Australian Food Composition Database (AFCD). Each food shows where its data comes from.
  • All recipes are original NourishFix recipes, written for the planner. Our dietitian is reviewing each one before the planner leaves beta.
  • NourishFix doesn’t diagnose, treat, adjust medication or replace advice from your care team. Check with them before changing your diet, especially if you have a health condition.

Use of AI

We use AI tools only to help research our articles, for example to find studies and guidelines to read. AI doesn’t write our articles or decide what we recommend. A registered dietitian writes every article and checks every fact and number against its original source. The meal planner builds plans with fixed rules, not AI.

Independence and how we're funded

NourishFix does not accept sponsored content, paid product placements, or affiliate arrangements that influence editorial decisions. Articles are written and reviewed on the basis of the evidence and its relevance to the people we serve.

NourishFix is run by its founder. The meal planner is free during its beta. After that, it will move to a paid subscription with a free trial, and the no-cook meal finder will stay free. Our articles sometimes link to the planner, but what we write is decided by the evidence, not by what we offer.

Corrections and feedback

If you spot an error, an out-of-date figure or a broken reference, email hello@nourishfix.com. We read every report. When we find a factual error, we correct it promptly. For significant corrections, we add a note at the end of the article saying what changed and when.
