Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Omega-9 fatty acids, primarily oleic acid found in olive oil and other plant sources, have some scientific evidence supporting their role in cardiovascular health, including arteriosclerosis (hardening and narrowing of the arteries). Several epidemiological and clinical studies suggest that diets rich in monounsaturated fats like omega-9 are associated with improved lipid profiles, reduced LDL ("bad") cholesterol, and increased HDL ("good") cholesterol. These effects can contribute to a reduced risk of arterial plaque formation and progression of arteriosclerosis. The Mediterranean diet—rich in omega-9 due to its high olive oil content—has been linked to reduced rates of cardiovascular disease. However, direct studies specifically investigating omega-9 supplementation or intake as a treatment or targeted support for arteriosclerosis are limited. The evidence is largely extrapolated from broader dietary pattern studies rather than focused clinical trials. The mechanisms believed to be involved include anti-inflammatory effects, improved endothelial function, and favorable changes in blood lipids. In summary, while there is scientific rationale and some supportive evidence for omega-9 in cardiovascular health, the direct evidence for its use in treating or preventing arteriosclerosis specifically is limited, and thus the strength of evidence is moderate at best.
