Questions and Answers
How does a diet high in saturated fatty acids correlate with cardiovascular disease?
It is correlated with an increased incidence of cardiovascular disease.
What distinguishes canola oil's fatty acid composition from palm oil?
Canola oil has a very low saturated fat content and is high in unsaturated fatty acids, while palm oil is high in saturated palmitic acid.
What was the historical use of rapeseed oil before it became known as canola oil?

Study Notes
Fats in the Modern Diet
- The incidence of cardiovascular disease is correlated with diets high in saturated fatty acids.
- Diets higher in unsaturated fatty acids, especially polyunsaturated fatty acids, may reduce the risk of heart attacks and strokes.
- Vegetable oils generally contain higher proportions of unsaturated fatty acids compared to animal oils and fats.
- Palm oil is low in polyunsaturated fatty acids and high in palmitic acid, a saturated fatty acid.
- Coconut oil is high in lauric and myristic acids, both saturated fatty acids, and low in unsaturated fatty acids.
- Canola oil, derived from rapeseed, is considered a healthier dietary oil due to its high content of oleic acid, linoleic acid, and α-linolenic acid, and low saturated fat content.
- Rapeseed oil was traditionally used as a lamp oil because of its high erucic acid content, a monounsaturated fatty acid.
- In the 20th century, rapeseed oil was used as a steam engine lubricant.
- Through breeding techniques, the erucic acid content in rapeseed has been reduced to less than 1%, resulting in "canola oil".
