What the research says
1 study reviewedSupporting (1)
Cross-Sectional StudyHuman2025
People who ate more fatty fish like sardines were about half as likely to have a fatty liver, which is a warning sign for diabetes. So eating sardines regularly may help keep the body’s metabolism healthier and lower the chance of getting diabetes.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
