While canola and rapeseed are closely related and come from the same plant family, they are not exactly the same. Canola is a specific type of rapeseed that has been bred to have low levels of eruric acid and glucosinolates making it suitable for human consumption as an edible oil. Traditional rapeseed may contain higher levels of these compounds, which can be undesirable in food products. Here's a more detailed breakdown:
- Rapeseed: This is the broader term for a plant in the Brassica genus, cultivated for its oil-rich seeds.
- Canola: This is a specific variety of rapeseed that was developed in Canada through selective breeding to reduce the levels of erucic acid and glucosinolates in the oil.
- Erucic Acid: A fatty acid found in rapeseed oil that, in high concentrations, can be harmful to humans.
- Glucosinolates: Compounds found in rapeseed that can have a bitter taste and, in high concentrations, may also be undesirable in food.
In essence, canola is a type of rapeseed that has been modified to be a healthier edible oil, while rapeseed can refer to varieties with higher levels of erucic acid and glucosinolates, which are often used for industrial purposes
Canola oil has become a staple in kitchens and food industries worldwide, recognized for its versatility and nutritional profile.1 Developed in Canada from the rapeseed plant, it has carved out a significant niche in the global edible oil market.
What is Canola Oil? The Main Ingredient
Canola oil is extracted from the seeds of the canola plant (Brassica napus or Brassica rapa), a specially bred variety of the rapeseed plant. The name "canola" itself is a portmanteau of "Canadian" and "oil, low acid," reflecting its origins and key characteristic.
The development of canola in the 1960s and 70s by Canadian plant breeders aimed to reduce the high levels of erucic acid and glucosinolates naturally present in traditional rapeseed oil, making it safe and desirable for human consumption.5 Today, to be classified as canola, the oil must contain less than 2% erucic acid, and the meal must contain less than 30 micromoles of glucosinolates.6
After harvesting, canola seeds are crushed to extract the oil.7 This process often involves heating and flaking the seeds, followed by solvent extraction (typically using hexane, which is then removed) to maximize oil yield.8 The extracted oil is then refined to create a clear, neutral-tasting product with a long shelf life.9
Major Producers of Canola Oil
Canada is the undisputed world leader in canola production and export, accounting for over 30% of global supply and more than 60% of the export trade.10 The vast majority of Canadian canola is grown in the Prairie Provinces (Saskatchewan, Alberta, and Manitoba).
Other significant global producers include:
- China
- India
- Australia
- Russia
- European Union (collectively, with Germany and France being major producers)
- United States (primarily North Dakota)11
The demand for canola, especially in the US, often outstrips domestic supply, leading to substantial imports from Canada.
Canola Oil Nutrition
Canola oil is highly regarded for its favorable fatty acid profile.12 A single tablespoon (14g) of canola oil typically provides:
- Calories: ~124 calories13
- Total Fat: 14g14
- Saturated Fat: ~1g (one of the lowest among common cooking oils)
- Monounsaturated Fat: ~9g (primarily oleic acid, an omega-9 fatty acid)
- Polyunsaturated Fat: ~3.5g (including essential omega-3 and omega-6 fatty acids)15
- Trans Fat: 0g
- Cholesterol: 0mg
- Other nutrients: Canola oil is also a good source of Vitamin E (an antioxidant) and Vitamin K.16
Notably, canola oil has an excellent omega-6 to omega-3 fatty acid ratio (approximately 2:1), making it one of the few common cooking oils to offer a significant amount of the essential omega-3 alpha-linolenic acid (ALA).
Comparison with Other Oils
Here's a brief comparison of canola oil with some other popular cooking oils:
Oil Type | Saturated Fat (per tbsp) | Monounsaturated Fat (per tbsp) | Polyunsaturated Fat (per tbsp) | Omega-3 (ALA) Content | Smoke Point | Flavor Profile |
Canola Oil | ~1g | ~9g | ~3.5g | High | 400-475°F (refined) | Neutral |
Olive Oil | ~2g | ~10g | ~1.5g | Low | 375°F (Extra Virgin) | Fruity/Peppery |
Sunflower Oil | ~1.5g | ~2.5-11g (varies by type) | ~9g (varies by type) | Low | 450°F (refined) | Neutral |
Soybean Oil | ~2g | ~3g | ~8g | Moderate | 450°F (refined) | Neutral |
Vegetable Oil | ~2g | ~5.5g | ~5.5g | Moderate | 400-450°F (blend) | Neutral |
Coconut Oil | ~12g | ~0.8g | ~0.2g | None | 350°F | Coconut |
Note: "Vegetable oil" is often a blend of various oils, commonly including soybean, corn, or sunflower oil, and its nutritional profile can vary.17
Good and Bad Health Benefits
Canola oil is generally considered a heart-healthy oil due to its fat profile:18
Good Health Benefits:
- Heart Health: Its low saturated fat content and high levels of monounsaturated and polyunsaturated fats (including omega-3 ALA) can help reduce LDL ("bad") cholesterol levels, thereby lowering the risk of heart disease.19
- Omega-3 Source: As one of the best plant-based sources of ALA, it contributes to overall health, including brain health and reducing inflammation.20
- Vitamin E: Provides a good source of Vitamin E, an antioxidant that protects cells from damage.21
- Reduced Inflammation: Some studies suggest that the fatty acids in canola oil may help reduce biomarkers of inflammation.
Potential Concerns/Considerations:
While largely positive, some debate surrounds canola oil, often stemming from its processing and genetic modification:
- Processing: Most canola oil undergoes refining, bleaching, and deodorizing (RBD) processes, which can involve high heat and chemical solvents (like hexane).22 While the final product is safe and highly refined, some prefer less processed oils like extra virgin olive oil.
- GMO Status: A significant portion of canola is genetically modified (GM) for herbicide tolerance.23 While regulatory bodies worldwide deem GM canola safe, some consumers prefer non-GMO options. However, the oil itself is highly refined, meaning proteins (including those from GM modifications) are removed, making the oil identical regardless of GM origin.24
- Oxidation at High Heat: Like all polyunsaturated fatty acid-rich oils, canola oil can be susceptible to oxidation when exposed to very high heat for prolonged periods.25 However, its balanced fatty acid profile and high smoke point make it suitable for most standard cooking applications.
- Omega-6 Balance: While it has a good omega-6 to omega-3 ratio among cooking oils, maintaining an overall healthy balance of these fatty acids in the diet is important.
USMCA and Canola Oil Supply, Price, and Availability in the USA
The United States-Mexico-Canada Agreement (USMCA), which replaced NAFTA, has a significant and generally positive impact on canola oil's supply, price, and availability in the USA.
- Continued Free Trade: The USMCA essentially preserves the duty-free trade of agricultural products between Canada and the U.S. This ensures that Canadian canola and canola oil can continue to enter the US market without tariffs, which keeps prices competitive.
- Stable Supply: Canada's position as the leading producer and the integrated supply chains mean a consistent and reliable supply of canola oil for the US market. The agreement reinforces this stability.
- Increased Demand from Biofuels: A major development is the approval of canola oil for use in U.S. renewable fuel production (e.g., biodiesel, sustainable aviation fuel). This has significantly increased US demand for Canadian canola and canola oil. This increased demand could, in the long term, put upward pressure on prices, but it also incentivizes Canadian farmers to expand production, ensuring continued availability.
- Availability: Canola oil is widely available in the US, from supermarkets to industrial food manufacturers, largely thanks to this strong cross-border trade.
In essence, the USMCA solidifies the existing robust trade relationship, ensuring that canola oil remains a readily available and competitively priced option for US consumers and industries.
