Committed to Accuracy,
Transparency & Trust
At Dietproductguide, every article, food guide, and nutritional insight we publish is grounded in carefully vetted information. We hold our editorial process to a rigorous standard so that our readers in France and beyond can make informed choices about their nutrition and well-being with confidence.
Our Source Categories
We draw from a diverse but selective set of source types — each chosen for its reliability, independence, and relevance to nutrition science and healthy eating. Below you will find the five pillars of our information sourcing.
Peer-Reviewed Research
We prioritise studies published in reputable, peer-reviewed academic journals such as the Journal of Nutrition, Nutrients, and Obesity Reviews. Our editorial team checks the study methodology, sample sizes, and researcher affiliations before citing any finding. We avoid relying on single, unpublished or preliminary studies without contextualising their limitations for our readers.
Government & Public Health Agencies
Official nutritional guidelines issued by bodies such as Santé publique France, the EFSA (European Food Safety Authority), and the World Health Organization form a core reference point for our dietary content. These organisations compile and regularly update evidence-based dietary recommendations that reflect the current scientific consensus. We cross-reference their guidance whenever we cover topics related to caloric intake, macronutrients, or food safety.
Registered Nutrition Professionals
Our content is regularly reviewed or informed by registered dietitians and certified nutrition professionals with verifiable qualifications. These contributors provide real-world context that helps translate complex research into practical, everyday guidance. We disclose when content has been reviewed by an external expert and always indicate their area of specialisation so readers can evaluate the source.
Established Nutritional Databases
For specific data points such as calorie counts, macronutrient profiles, fibre content, and vitamin compositions, we consult established food composition databases including Ciqual (ANSES, France), USDA FoodData Central, and the Open Food Facts database. Using standardised databases ensures that the figures we present are consistent, traceable, and based on systematic food analysis rather than estimates.
Reputable Health Publications
In addition to primary research, we monitor respected science and health journalism outlets — including The Lancet editorials, Harvard Health Publishing, and The BMJ — for developments in nutritional science. These secondary sources help our editorial team stay current with evolving conversations in the field. However, we always trace their claims back to original research before incorporating them into our own content.
What We Do Not Use
We do not cite anonymous online communities, influencer claims, brand-sponsored content, or unpeer-reviewed preprints as primary evidence. We also do not present anecdotal reports — no matter how widespread — as factual nutritional guidance. If a popular claim lacks robust scientific backing, our editorial team will say so explicitly rather than pass it along uncritically to our readers.

Our Verification Process
Every piece of content published on Dietproductguide passes through a structured editorial review before it reaches our readers. This process is designed to prevent misinformation from slipping through and to ensure that our nutrition content reflects the best available evidence — not trends or wishful thinking.
-
1
Initial Research & Source Gathering
Writers are required to gather at least three independent primary sources for any factual claim before drafting begins. Sources are listed in a working document that accompanies each article throughout the review cycle.
-
2
Editorial Cross-Check
A senior editor reviews the draft against all cited sources, verifying that claims have not been overstated or taken out of context. Any statement that cannot be independently confirmed is either reworded with appropriate hedging or removed entirely.
-
3
Specialist Review (Where Applicable)
For articles covering specific dietary approaches, nutrient interactions, or weight management strategies, we request a review from a nutrition professional in the relevant specialisation. Their feedback is incorporated before publication, and their involvement is noted in the article.
-
4
Post-Publication Monitoring
Our editorial calendar includes scheduled reviews of older content to check whether cited studies have been retracted, updated guidance has been issued, or new evidence significantly changes the picture. Outdated articles are either updated with a revision note or clearly marked as no longer current.
Our Disclosure Policy
We believe that our readers have the right to know who creates our content, what informs it, and whether any relationships might influence what we publish. Below is a plain-language summary of how we handle disclosures.
Affiliate & Partner Links
Some articles on Dietproductguide may contain links to external resources or products that are marked with a [Partenaire] label. These are affiliate relationships. The presence of such a link never influences the editorial position of the article in which it appears — our assessments are written before any commercial arrangement is considered.
Authorship & Editorial Independence
All content is written and edited by our internal editorial team or by clearly identified external contributors. No brand, advertiser, or third-party organisation has editorial authority over our articles. Contributors are identified by name and, where relevant, by professional background. Sponsored content, if ever published, is clearly marked as such and separated from editorial content.
Content Updates & Corrections
When we update an existing article to reflect new research or correct an error, we add a visible revision note at the top of the page stating the date and nature of the change. We do not silently edit published content in ways that could mislead readers about what was originally stated. If a factual error is significant, we publish a brief correction notice alongside the update.
Reader Feedback & Error Reports
If you believe any content on our site contains a factual inaccuracy or references a source incorrectly, we encourage you to contact our editorial team directly at [email protected]. Reader-submitted corrections are reviewed within a reasonable timeframe and, when valid, acted upon with full transparency.
No Advertiser Influence on Content
Dietproductguide maintains a strict separation between our advertising and editorial operations. Advertisers who appear on this site do not have access to article drafts, cannot request changes to published content, and do not influence which topics we cover or how we cover them. Our editorial agenda is set exclusively by reader interest and nutritional relevance.
Informational Purpose Only
The content on this site is published for general informational and educational purposes. It is not intended to replace personalised advice from a qualified nutrition professional. We state this clearly on relevant articles and in our full disclaimer, which is available at any time via our site navigation. Readers are encouraged to consult a registered dietitian for individual guidance.
