The Claim
Does oleic acid reduce risk of diabetes and high blood pressure?
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who eat more olive oil and nuts — which are rich in oleic acid — are much less likely to develop diabetes or high blood pressure, possibly because this fat helps the body use insulin better and keeps blood vessels healthy.
See the scientific wording
Higher intake of oleic acid (C18:1) is associated with a 48% to 79% lower likelihood of type-2 diabetes and a 48% lower likelihood of hypertension in adults from southern Italy, suggesting this monounsaturated fatty acid may contribute to improved cardio-metabolic health.
What the research says
1 studyStudy: Dietary Fats and Cardio-Metabolic Outcomes in a Cohort of Italian Adults
This study found that people in southern Italy who ate more oleic acid (a healthy fat found in olive oil) were much less likely to have type-2 diabetes or high blood pressure, which matches what the claim says.
