How Root Cause Guides Are Made

Research first

Each guide is built from peer-reviewed studies, mostly from PubMed. Meta-analyses, systematic reviews and randomized trials come first. Smaller observational studies are included when they add something, with their size and limits stated plainly.

Honest about evidence

Food and acne research is still young. When a link is an association rather than proof, the guide says so. When a trial was small, short or done in a narrow group, the guide says that too. Every factual claim links to its source at the end of the page.

No blanket food rules

Cutting whole food groups helps some people and does nothing for others. The guides focus on what the research shows and on testing your own triggers, so you can keep the foods that don't affect you.

Kept up to date

Guides are reviewed as new studies come out, and the updated date at the top of each page shows the last revision.

Not medical advice

Root Cause is an educational pattern-finding tool, not a healthcare provider. The guides do not diagnose, treat, cure or prevent acne or any medical condition. Always check with a dermatologist or doctor before changing your diet or treatment.
