Our Primary Information Sources
Peer-Reviewed Research
Our team regularly consults peer-reviewed journals and scientific publications including the American Journal of Clinical Nutrition, Nutrition Reviews, and the International Journal of Obesity. We prioritize studies that have undergone rigorous editorial review and been published in reputable academic databases such as PubMed and Google Scholar. Each recommendation we make is supported by multiple studies or meta-analyses rather than isolated findings. This approach ensures that our meal planning principles reflect the current scientific consensus on nutrition and dietary health.
Government & Health Agencies
We reference guidelines from authoritative public health organizations including the Spanish Ministry of Health, the European Food Safety Authority (EFSA), the World Health Organization (WHO), and the United States National Institutes of Health (NIH). These agencies publish dietary recommendations based on extensive research reviews conducted by panels of independent experts. Their guidelines on macronutrient distribution, micronutrient requirements, and healthy eating patterns form a foundational reference point for our coaching programs and content.
Professional Nutrition Organizations
We align with evidence-based standards established by the Academy of Nutrition and Dietetics, the British Dietetic Association, and the European Federation of the Associations of Dietitians. These professional bodies represent registered dietitian nutritionists and continuously update their position papers on topics like plant-based nutrition, sports nutrition, and medical nutrition therapy. Their systematic reviews and consensus statements guide our approach to meal planning across different life stages and dietary preferences.
Clinical Research & Nutritional Studies
We monitor ongoing clinical research from leading academic institutions and teaching hospitals. Our team reviews randomized controlled trials, cohort studies, and prospective nutritional research that examines the relationship between diet and overall wellness. We stay informed about emerging research on topics such as nutrient bioavailability, food synergy, and individual nutritional variability. This allows us to continuously refine our meal planning approaches as new evidence becomes available.
Industry Experts & Registered Dietitians
Our editorial board includes registered dietitian nutritionists with years of practical experience in nutrition counseling, meal planning, and client coaching. We consult with specialists in sports nutrition, pediatric nutrition, and plant-based diets to ensure our content reflects real-world best practices. These professionals contribute peer-reviewed insights and help us translate complex nutritional science into actionable, practical guidance that our community can implement.
Food & Nutritional Composition Databases
For nutritional information and food composition data, we rely on verified databases such as the USDA FoodData Central, the European Food Safety Authority's food composition database, and Spain's official food composition tables. These databases are maintained by government agencies and regularly updated with laboratory-tested nutritional values. We cross-reference multiple sources when providing specific nutrient content for meal planning recommendations to ensure accuracy and reliability.
Our Verification Process
Source Evaluation
Before any information is included in our content, we evaluate the credibility of its source. We assess the author's qualifications, the publication's peer-review process (if applicable), the funding sources, and any potential biases. We prioritize primary research over secondary summaries and check whether studies have been replicated or supported by multiple independent researchers. This critical evaluation step ensures that we only feature information from credible, trustworthy sources.
Multi-Source Verification
For significant nutrition claims or recommendations, we consult at least two to three independent, credible sources. This cross-referencing approach helps us identify consensus areas in the research and highlights where legitimate scientific debate exists. If sources disagree, we present the different perspectives transparently rather than choosing one arbitrarily. This methodical verification ensures that our guidance reflects well-supported scientific positions.
Editorial Review
Every article and resource on our platform undergoes review by a member of our editorial team—typically a registered dietitian nutritionist or nutrition specialist with relevant expertise. The reviewer checks that all claims are supported by cited sources, that language is clear and accurate, and that recommendations align with current evidence-based guidelines. This internal peer-review process adds an additional layer of quality assurance before content is published.
Currency & Regular Updates
Nutritional science is continuously evolving. We regularly review and update our content to reflect new research findings and updated guidelines. Each article includes a publication date and last update date so you know how current the information is. If significant new research emerges that changes our understanding of a topic, we update the relevant content promptly and clearly note what changed. This commitment to staying current ensures our advice remains aligned with the latest evidence.
Continuous Community Feedback
We value feedback from our community members and dietary professionals. If you notice an inaccuracy, outdated information, or have a question about our sources, we encourage you to contact our editorial team. Your insights help us maintain the highest standards of accuracy and relevance. We take all feedback seriously and investigate reported issues promptly, making corrections when warranted and explaining our reasoning to our readers.
Our Disclosure & Transparency Policy
Conflict of Interest Disclosure
We maintain strict independence from commercial interests. Our editorial team does not accept sponsorships or funding from food companies, supplement manufacturers, or organizations with a direct financial stake in diet-related products. Any partnerships we do engage in are clearly disclosed. If an article mentions a specific brand or product, we disclose any financial relationships and maintain editorial independence in our assessment of that product's evidence base.
Transparent Source Citation
All substantive claims in our articles are supported by citations to published sources. We provide links to peer-reviewed studies, government resources, and professional guidelines wherever possible. Our in-text citations allow you to review the original research yourself and understand the basis for our recommendations. We believe transparency about our sources builds trust and empowers our readers to make informed dietary decisions.
Author Expertise & Credentials
Each article includes author credentials so you understand their background and qualifications. Our team consists of registered dietitian nutritionists, nutrition scientists, and experienced health writers. We believe you have a right to know who is providing information about your nutrition. Author profiles are available with contact information for questions related to their content or expertise.
Clear Limitations & Disclaimers
Our content is educational in nature and is not intended to replace individualized nutrition guidance from a qualified healthcare provider. We clearly state the limitations of our information and note where individual circumstances, allergies, or preferences may require professional consultation. Articles acknowledge areas of scientific debate and explain where expert opinion differs on certain nutrition topics.
Publication Dating & Version History
Every article displays a publication date and last-updated date prominently. This transparency helps you assess the currency of the information. When we make significant updates to articles, we note what changed and why, allowing you to understand how our recommendations may have evolved. We archive older versions of significantly updated articles so readers can see how our understanding has developed.
Editorial Independence
Our editorial decisions are made independently by our nutrition and content experts, not influenced by commercial considerations. We follow strict editorial guidelines that prioritize accuracy and evidence over marketing appeal. Our team regularly reviews our own work through the lens of these standards, asking whether our content serves the reader's interests in understanding nutrition science.
How We Evaluate Evidence
We use a hierarchy of evidence to assess the strength of nutrition research. This framework helps us communicate how much confidence we have in different recommendations.
High-Quality Evidence
Multiple well-designed randomized controlled trials or a meta-analysis of such trials. Consistency across independent studies and populations. Large sample sizes with relevant follow-up periods. We recommend with confidence when this level of evidence exists.
Moderate-Quality Evidence
Some randomized controlled trials or well-designed observational studies showing consistent findings. May have limitations in sample size, design, or applicability. We present these recommendations with appropriate context about their strength.
Lower-Quality Evidence or Expert Opinion
Limited research, small studies, or consensus from experienced practitioners. We clearly label these as expert recommendations rather than evidence-based conclusions and explain the reasoning behind them.
Insufficient Evidence
When research is limited, conflicting, or absent, we say so explicitly. We don't speculate or present unproven ideas as facts. We explain what we know, what we don't know, and where further research is needed.
