Our Research & Content Methodology
At Nutritionplanpath, we follow a rigorous, transparent process to develop evidence-based nutrition guidance. Every article, guide, and recommendation undergoes multiple quality checkpoints and expert review to ensure accuracy, relevance, and practical value for our readers in Spain and beyond.
The information on this site is for educational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional before making health decisions.
Why Methodology Matters
Nutrition science evolves constantly. New research emerges, dietary patterns shift, and individual needs vary widely. Our commitment is to bridge the gap between cutting-edge science and practical, actionable advice that readers can implement in their daily lives. We believe transparency about our research process builds trust and ensures you know exactly how our recommendations are formed.
Every piece of content published on Nutritionplanpath reflects months of research synthesis, expert consultation, and iterative refinement. We don't publish opinion—we publish evidence-informed guidance that has been stress-tested by our editorial and scientific review teams.
This methodology page documents exactly how we do it, from source selection through final publication, so you can evaluate our work with confidence.
Our Six-Step Content Development Process
Topic Selection & Scoping
We identify topics that matter to our Spanish-speaking audience and fill gaps in existing nutrition guidance. Our editorial team reviews trending questions, reader feedback, and emerging research areas. Each topic is scoped with a brief outlining the target audience, learning objectives, and key subtopics to cover. This ensures focus and prevents unfocused rambling.
Primary Source Research
Our researchers conduct systematic searches through peer-reviewed databases: PubMed, Google Scholar, Web of Science, and the Cochrane Library. We prioritize recent studies (within 5–10 years) and focus on randomized controlled trials, meta-analyses, and systematic reviews over observational studies. All sources are documented with DOI or URL for transparency and reader verification.
Evidence Synthesis & Writer Briefing
Research findings are synthesized into a structured brief document that outlines key findings, consensus positions, areas of debate, and conflicting evidence. This brief is handed to our writer along with a style guide and audience context. Writers are instructed to prioritize clarity over jargon and to flag any claims that lack strong support.
Draft Development & Internal Review
Writers produce a first draft incorporating research findings and reader-friendly explanations. The draft undergoes internal editorial review for accuracy, clarity, tone, and completeness. Editors verify all citations and check for unsupported claims, outdated information, or conflicting statements. A revision round ensures the piece meets our quality standards before external review.
Expert & Scientific Review
Depending on topic complexity, we submit drafts to registered dietitians, nutritionists, or academic specialists for fact-checking and feedback. These experts verify that claims are scientifically sound, contextualized appropriately, and not overstated. Their input is documented and incorporated into the final revision.
Publication, Attribution & Maintenance
Articles are published with author bylines, publication date, and last-updated timestamp. All sources are linked in bibliography sections. We monitor published content for outdated science and update articles when new evidence emerges or recommendations change. Each update is documented in a changelog visible to readers.
Research Source Hierarchy
We prioritize evidence based on quality and relevance. This hierarchy guides our source selection and helps us integrate findings appropriately into our recommendations.
Tier 1: Gold Standard
- • Systematic reviews & meta-analyses from Cochrane or peer-reviewed journals
- • Randomized controlled trials (RCTs) in reputable journals (impact factor >3)
- • Guidelines from established bodies (Spanish Association of Dietitians, European Nutrition Society)
- • Government health agency reports (Spanish Ministry of Health, EFSA)
Tier 2: Strong Evidence
- • Cohort and cross-sectional studies with large sample sizes (n > 500)
- • Narrative reviews in peer-reviewed journals by recognized experts
- • Position papers from professional nutrition organizations
- • Consensus statements from interdisciplinary expert panels
Tier 3: Contextual Evidence
- • Expert opinion from qualified dietitians and researchers (used to contextualize, not ground claims)
- • Case studies and qualitative research (acknowledged as anecdotal but illustrative)
- • Industry white papers from reputable organizations (clearly labeled as promotional context)
Tier 4: Excluded / Flagged
- • Unreplicated single studies without peer review
- • Anonymous or unverifiable blog posts and commercial websites
- • Sources with undisclosed conflicts of interest or financial bias
- • Retracted papers or sources citing retracted research

Case Study: How We Created Our Vitamin D Article
Background
We identified that many Spanish readers ask about vitamin D supplementation, especially in winter months. Current online guidance was scattered, contradictory, and often promotional. We decided to create a comprehensive guide addressing: What is vitamin D? Why is it important? Who needs supplementation? What does the science say about dosing and safety?
Research Phase (3 weeks)
- Week 1: Literature search across PubMed, Cochrane, and WHO databases for vitamin D RCTs and meta-analyses published 2018–2024
- Week 2: Reviewed 60+ papers; synthesized findings into brief document summarizing consensus (supplementation effective for bone health in at-risk populations) and debates (optimal serum levels still contested)
- Week 3: Created writer brief with 8 key claims, supporting citations (DOI included), and editorial flags (e.g., "Note: sunlight synthesis varies by latitude and skin tone—discuss Spain-specific context")
Writing & Internal Review (2 weeks)
- Week 1: Writer produced 3,500-word draft with sections on biochemistry, sun exposure recommendations for Spanish latitudes, supplementation options, and safe dosing ranges
- Week 2: Internal review by nutrition experts, fact-checking against 40+ peer-reviewed sources, edits for clarity and SEO optimization
Publication & Distribution (1 week)
- Published on Nutritionplanpath blog with embedded callouts, downloadable vitamin D checklist, and internal links to related guides
- Promoted via email to 15,000+ subscribers and shared across social media channels
