Which sources provide evidence-based wellness guidelines?

• A. Personal blogs
• B. Social media testimonials
• C. National guidelines and peer-reviewed literature
• D. Marketing brochures

Answer: (C)

Evidence-based wellness guidelines come from sources that systematically evaluate research and base recommendations on high-quality evidence. National guidelines are created by expert panels who review the best available studies, weigh benefits and harms, and produce clear, actionable recommendations for populations or conditions. Peer-reviewed literature includes original research and reviews that have undergone formal critique by other scientists, ensuring methods and conclusions are scrutinized before they’re published.

In contrast, sources like personal blogs, social media testimonials, and marketing brochures often reflect individual opinions, anecdotes, or promotional aims rather than a formal appraisal of evidence. They don’t provide the rigorous, balanced assessment that underpins evidence-based guidelines. So the best sources for evidence-based wellness guidelines are national guidelines and peer-reviewed literature.
