Your science-based nutrition guide, created by real people for real people
MacroGuia was created to fight nutritional misinformation. In a world saturated with miracle diets, biased influencers and content without scientific backing, we believe everyone deserves access to clear, rigorous and free information to make better decisions about their diet.
We do not sell supplements, we do not promote miracle products and we do not have commercial relationships that influence our content. Our only interest is that you have access to the same information that research provides, explained in a way that is easy to understand and apply.
Each topic starts with a review of studies indexed in PubMed, Cochrane Library and peer-reviewed journals. We prioritize systematic reviews and meta-analyses.
The information is synthesized and written in accessible language, without losing scientific rigor. Technical concepts are explained with practical examples.
All data, figures and recommendations are verified against primary sources before publication. We cite the source of each key claim.
Nutrition is an evolving science. We review and update articles when relevant new studies are published or official guidelines change.
