Sacha Inchi (Plukenetia volubilis), also known as Inca peanut, is rich in alpha-linolenic acid (ALA), an omega-3 fatty acid. Scientific studies have demonstrated that regular intake of omega-3 fatty acids can contribute to cardiovascular health by reducing blood pressure, improving lipid profiles, decreasing inflammation, and enhancing endothelial function — all of which support arterial health. Several small-scale human clinical trials and animal studies have specifically examined Sacha Inchi oil. For example, a 2011 study (Cardiovascular Therapeutics, Garmendia et al.) found that supplementation with Sacha Inchi oil improved serum lipid profiles in humans, especially increasing HDL ("good cholesterol") and decreasing LDL ("bad cholesterol"), both relevant to arterial health. Additionally, the high content of polyunsaturated fatty acids and antioxidant compounds in Sacha Inchi oil may provide further vascular benefits by reducing oxidative stress. However, while these findings are promising, most clinical evidence is limited to surrogate markers such as cholesterol levels rather than direct measures of arterial function or clinical outcomes like heart attack or stroke. Thus, while there is scientific support for Sacha Inchi benefiting arterial health, the evidence base is moderate and largely extrapolated from related research on dietary omega-3s rather than large, long-term clinical trials specific to Sacha Inchi itself.
