The Core Difference: Saturated Fat Content
When evaluating cooking oils, understanding the saturated fat content is a crucial starting point for many health discussions. The fundamental answer to the question—what has more saturated fat, olive oil or canola oil—is that olive oil contains a higher percentage. The specific breakdown of each oil, however, reveals a more nuanced nutritional profile that impacts its health benefits and culinary uses.
Canola Oil's Fat Profile
Canola oil, derived from the rapeseed plant, is notable for its very low saturated fat content. Typically, canola oil consists of only about 7% saturated fat. Its fat composition is predominantly heart-healthy unsaturated fats, including a significant amount of monounsaturated fats (around 64%) and polyunsaturated fats (around 28%). A key benefit of canola oil is its high content of alpha-linolenic acid (ALA), a plant-based omega-3 fatty acid, which is essential for human health.
Olive Oil's Fat Profile
Olive oil, which is the pressed fruit of the olive tree, has a higher percentage of saturated fat than canola oil, typically around 14%. However, the majority of olive oil's fat content is monounsaturated fat (around 73%), primarily oleic acid. Extra virgin olive oil (EVOO), the highest quality and least processed type, may have slightly less saturated fat than refined olive oils. The rich monounsaturated fat profile and high antioxidant content are the primary reasons for olive oil's widespread reputation as a healthy fat source.
A Head-to-Head Nutritional Comparison
To make an informed decision, it's helpful to see the key nutritional aspects side-by-side. The following table provides a quick overview based on a typical tablespoon serving.
| Feature | Canola Oil | Olive Oil |
|---|---|---|
| Saturated Fat | ~7% of fat content | ~14% of fat content |
| Monounsaturated Fat | ~64% of fat content | ~73% of fat content |
| Polyunsaturated Fat | ~28% of fat content | ~12% of fat content |
| Omega-3s (ALA) | Highest among common oils | Lower content |
| Processing | Typically refined (RBD) | Varies (extra virgin, virgin, refined) |
| Antioxidants | Contains vitamin E | Rich in polyphenols and vitamin E (especially EVOO) |
| Smoke Point | High (~468°F/242°C) | Varies (EVOO lower, refined higher) |
| Flavor | Neutral, mild | Ranges from peppery (EVOO) to neutral |
Beyond Saturated Fat: Other Health Considerations
While saturated fat is a significant metric, it doesn't tell the full story. Both olive oil and canola oil offer distinct health benefits.
The Importance of Monounsaturated Fats
Both oils are excellent sources of monounsaturated fats, which are known to improve cholesterol levels by lowering LDL ('bad') cholesterol. While olive oil has a higher percentage of these fats, both can contribute positively to cardiovascular health when used to replace less healthy saturated fats.
Antioxidants and Processing
Extra virgin olive oil is particularly rich in antioxidants, such as polyphenols, which give it potent anti-inflammatory properties and protect against cellular damage. The cold-pressing process used to produce EVOO helps retain these beneficial compounds. Canola oil, while containing some vitamin E, is typically more refined, a process that can strip away some nutrients and lead to concerns about potential inflammatory markers when heated. However, modern refinement processes are generally considered safe.
Omega-3s: A Key Advantage for Canola
Canola oil provides a more substantial amount of plant-based omega-3 fatty acids (ALA) compared to olive oil. Omega-3s are vital for heart and brain health, and increasing their intake is a positive dietary goal for many people. For those who don't eat a lot of fatty fish, canola oil can be a useful dietary source of this essential nutrient.
Cooking with Olive Oil vs. Canola Oil
The choice of oil also depends on your cooking method due to differences in smoke point and flavor.
- High-Heat Cooking: Refined canola oil has a very high smoke point, making it suitable for deep-frying, searing, and high-temperature sautéing. Extra virgin olive oil, with its lower smoke point, is not ideal for high-heat cooking and can degrade into undesirable compounds when heated excessively.
- Flavor and Finishing: The robust, fruity, or peppery flavor of extra virgin olive oil is prized in dressings, marinades, and as a finishing drizzle over cooked dishes. Canola oil's neutral flavor makes it versatile for baking and sautéing where you don't want the oil's taste to interfere with the final product.
Choosing the Right Oil for Your Needs
The choice between olive oil and canola oil isn't about which is definitively 'better,' but rather which is more suitable for a particular culinary or health purpose. For high-heat cooking where a neutral flavor is desired, refined canola oil is an excellent and affordable choice with its low saturated fat content. For low-to-medium heat cooking, salad dressings, and finishing, extra virgin olive oil is unmatched for its flavor profile and antioxidant-rich qualities. Both oils, used in moderation, can be part of a healthy diet.
Ultimately, nutritional experts often recommend using a variety of healthy oils to get a broad range of nutrients. Focusing on replacing solid, saturated fats like butter with either olive or canola oil is a sound strategy for improving overall heart health.

Conclusion: What Has More Saturated Fat, Olive Oil or Canola Oil?
In summary, olive oil contains roughly twice the saturated fat of canola oil. However, this fact alone does not determine which is 'healthier.' Both are predominantly composed of beneficial unsaturated fats, particularly monounsaturated fats. Canola oil offers the advantage of lower saturated fat and a notable amount of omega-3s, while extra virgin olive oil is celebrated for its antioxidant content and superior flavor. The best choice depends on the application, balancing a high smoke point with neutral flavor for high-heat cooking (canola) against a rich antioxidant profile and robust flavor for lower-heat uses (extra virgin olive oil).
