These long-form guides cover topics that take more than a single article to get right — nutrition for longevity, brain health, life-stage-specific eating. Each guide pulls together the research across multiple areas and gives a practical framework you can actually apply.
The brain is the most energy-hungry organ you have. Here's what the research shows about which foods and nutrients actually support cognitive function, memory, and long-term brain health.
Read: how to eat for brain health →Blue Zone diets, caloric restriction, mTOR, and protein — here's what the research actually shows about which eating patterns extend healthspan and lifespan.
Read: nutrition for longevity →Hormonal shifts, bone density changes, and metabolic shifts after 40 mean your nutritional needs genuinely change. Here's what the evidence says to prioritise.
Read: nutrition for women over 40 →Articles answer one focused question ("How much protein per day?"). Guides cover a topic that needs multiple angles to do justice — nutrition for longevity, brain health, women over 40 — pulling research from across the pillars into a single practical framework.
Each guide starts from peer-reviewed sources and recommendations from public-health bodies (NIH, NHS, WHO, ISSN, EFSA). Claims are linked to a primary source, and every guide is reviewed by Nicole Adams, MPH, RD, CPT before publication.
At least once a year for any guide that touches a YMYL topic — anything where someone might change their diet or supplements based on what we said. We also revisit guides whenever a meaningful new study or guideline lands.
Start with the protein, fibre, and gut health basics — those three together cover most of the practical wins. Pick one guide and read it end-to-end; the others link into it where the topics overlap.
