The Science Behind Camelina Oil
The science behind Camelina Oil has been studied for its health benefits in humans and animals by scientists around the world. Some of the most recent and important scientific discoveries of camelina’s health benefits include:
Alpha-linolenic acid (ALA) is likely responsible for much of camelina oil’s cholesterol-lowering benefits. According to Iowa State University, 94% of the fatty acids in camelina oil are unsaturated, and 38% are ALA. For comparison’s sake, canola oil’s ALA content is 6.6%, and sunflower oil contains no ALA, per Oregon State University.
Karoven, et al. (2002) studied the effects of ALA-rich camelina sativa oil on serum fatty acid and cholesterol in individuals with high cholesterol. This study compared camelina oil to rapeseed and olive oils in a parallel, double-blind setting. After six weeks, subjects in the camelina group showed higher ALA levels 2.5X greater than the rapeseed group, and 4X higher than the olive oil group. More importantly, the study showed that serum LDL (“bad” cholesterol) was decreased significantly by 12.2% in the camelina group, 5.4% in the rapeseed group, and 7.7% in the olive oil group. Camelina oil significantly elevated the proportions of ALA and its metabolites and reduced serum cholesterol by 12.2%.
Devassy et al. (2016) published in Metabolism: Clinical and Experimental documented the benefits of ALA for reducing neuroinflammation in the improvement and management of Alzheimer’s disease in Advances in Nutrition. Devassy concludes that neuroinflammation plays an important role in the advancement of this disorder, and n–3 (Omega-3) polyunsaturated fatty acids (PUFAs), including plant-derived n-3 (Omega-3) ALA oxylipins, are involved in both the reduction in and resolution of inflammation associated with Alzheimer’s disease.
Manninen ed al. (2018) showed that camelina oil favorably affected the cardiovascular health of men and women with prediabetes in an article in the Journal of Molecular Nutrition & Food Research. This study suggests that fatty fish intake causes a shift toward larger high-density lipoprotein (HDL) particles and increases the concentration of HDL (“good cholesterol”), while intake of camelina sativa oil significantly decreases intermediate-density lipoprotein (IDL) particle size, leading to a decrease in serum LDL concentrations. These changes may favorably affect cardiovascular risk.
Manninen ed al (2018) in the Journal of Molecular Nutrition & Food Research showed that camelina sativa oil decreases the binding of lipoproteins to aortic proteoglycans by decreasing serum LDL cholesterol concentration, which suggests that the level of LDL lipoproteins in the circulation is the main driver of lipoprotein retention within the arterial wall. Simply put, camelina oil as a lipid-lowering therapy may help prevent heart attacks by reducing the potential for arterial plaque buildup.
