Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Canola oil is used to support fat metabolism primarily based on scientific evidence. Canola oil is low in saturated fat and high in monounsaturated fats, particularly oleic acid. It also contains a moderate amount of omega-3 alpha-linolenic acid (ALA), which is recognized for its beneficial effects on lipid profiles. Several studies have shown that replacing saturated fats with monounsaturated or polyunsaturated fats, such as those found in canola oil, can improve cholesterol levels and overall cardiovascular risk—key indicators of healthy fat metabolism.

Randomized controlled trials and meta-analyses have indicated that canola oil consumption can lower total cholesterol, LDL cholesterol, and, in some cases, triglycerides. For example, a meta-analysis published in Nutrition Reviews (2013) concluded that diets high in canola oil were associated with improved blood lipid profiles compared to those high in saturated fats. The mechanism involves canola oil's fatty acid composition, which helps regulate lipid metabolism enzymes and modulates hepatic fat processing. However, while canola oil can support fat metabolism in the context of dyslipidemia and cardiovascular health, there is less direct evidence that it specifically "treats" poor fat metabolism outside of its effects on blood lipids. Thus, the evidence for its use is moderate, meriting a rating of 3 out of 5.

There is little historical or traditional use of canola oil for this purpose, as it is a relatively modern oil developed in the 1970s. Its current use in supporting fat metabolism is grounded in nutritional science rather than tradition.
