What Is Canola Oil?

Check out this answer from Consensus:

Canola oil is a healthful cooking oil option due to its favorable fatty acid composition, which supports cardiovascular health and offers anti-inflammatory benefits. Its versatility in cooking and industrial applications further enhances its value. Regular consumption of canola oil, as part of a balanced diet, can contribute to improved health outcomes.

Canola oil is a widely used vegetable oil derived from the seeds of the canola plant, a cultivar of rapeseed. It is known for its low saturated fat content and high levels of monounsaturated fats, making it a popular choice for cooking and food production. This article explores the composition, health benefits, and applications of canola oil.

Composition of Canola Oil

Canola oil is rich in monounsaturated fatty acids (MUFAs), particularly oleic acid, and contains a significant amount of polyunsaturated fatty acids (PUFAs), including alpha-linolenic acid (ALA), an omega-3 fatty acid. It has a low saturated fatty acid (SFA) content, which contributes to its health benefits2 4 5. The oil’s fatty acid profile makes it a heart-healthy option, as it can help reduce cholesterol levels and improve lipid profiles2 4.

Health Benefits

1. Cardiovascular Health: Canola oil has been shown to lower total cholesterol and low-density lipoprotein (LDL) cholesterol levels, which are risk factors for cardiovascular disease. Diets enriched with canola oil can lead to improved lipid profiles and reduced cardiovascular disease risk2 4 5. Additionally, canola oil’s omega-3 content may help reduce inflammation and improve heart health1 6. 
2. Anti-inflammatory Effects: The presence of omega-3 fatty acids in canola oil contributes to its anti-inflammatory properties. Studies have shown that canola oil can increase adiponectin levels, a protein that plays a role in reducing inflammation and improving insulin sensitivity6. 
3. Improved Fatty Acid Profile in Dairy: When included in the diet of lactating dairy cows, canola oil can enhance the nutritional quality of milk by increasing its omega-3 and oleic acid content while reducing saturated fatty acids3. 

Applications

Canola oil is versatile and used in various culinary applications, including frying, baking, and salad dressings. Its neutral flavor and high smoke point make it suitable for high-temperature cooking. Beyond culinary uses, canola oil is also utilized in the production of biodiesel and as a lubricant in industrial applications.
