# Meixiong 2022 — Diet and acne

## Quick Summary

Systematic review used for broader diet-acne context and dairy-evidence caveats.

## What Studied

Systematic review of evidence on dietary glycemic load, dairy intake, and acnegenesis.

## Main Findings

The review described mixed dairy evidence that may vary by sex, ethnicity, and dietary context, and called for more randomized trials to characterize associations.

## Why It Matters

It keeps dairy guidance cautious and population-specific rather than turning diet observations into universal rules.
