Grapeseed Oil vs Canola Oil: Which Is Healthier?
When it comes to choosing cooking oils, two options that often come up are grapeseed oil and canola oil. But which of these oils is the healthier option?
Grapeseed and canola oil have slightly different nutritional profiles and smoke points. Understanding the pros and cons of each can help you determine which is better for your needs.
What Is Grapeseed Oil?
Grapeseed oil is extracted from grape seeds, a byproduct of winemaking. It has a high smoke point and clean, neutral flavor.
Grapeseed oil is low in saturated fat and high in polyunsaturated fat like linoleic acid (omega-6). It contains beneficial compounds like vitamin E and phenolic antioxidants.
Potential Benefits of Grapeseed Oil
Here are some of the evidence-based benefits of grapeseed oil:
- High in vitamin E to support immunity and heart health
- Contains linoleic acid, an essential omega-6 fatty acid
- Neutral flavor good for cooking and dressings
- High smoke point of approximately 420°F
- May reduce LDL cholesterol and blood pressure
- Rich in antioxidants to fight inflammation and cell damage
Overall, grapeseed oil is valued for its versatility, antioxidant content, and health benefits.
Downsides of Grapeseed Oil
Some potential downsides of grapeseed oil include:
- High omega-6 content may promote inflammation if consumed in excess
- Lacks omega-3 fatty acids
- Sustainability and farming practices are a concern for some brands
- Can become rancid more quickly than oils with antioxidants added
Eating grapeseed oil in moderation is key. It lacks omega-3s and overdoing omega-6s from grapeseed oil could negate benefits.
What Is Canola Oil?
Canola oil comes from rapeseed plants bred to have low erucic acid. It has a light flavor perfect for dressings, baking, and frying.
Like grapeseed oil, canola oil is low in saturated fat and rich in monounsaturated fat. It also contains omega-3 alpha-linolenic acid (ALA).
Potential Benefits of Canola Oil
Here are some evidence-based benefits of canola oil:
- Relatively high in heart-healthy monounsaturated fat
- Excellent ratio of omega-6 to omega-3 fatty acids
- Contains ALA omega-3 fatty acid
- Neutral flavor and high smoke point of 400°F
- May improve blood sugar control and heart health
- Often more affordable than other oils
Canola oil is highly versatile with research supporting its role in a healthy diet. The balance of fats may offer advantages over grapeseed oil.
Downsides of Canola Oil
Some drawbacks of canola oil include:
- Heavily processed and refined
- Originates from rapeseed, which is toxic in its raw form
- Up to 4% is trans fats, albeit harmless ones
- Some brands use solvents like hexane for extraction
- GMO varieties dominate commercial canola oil
While canola oil has health benefits, some are concerned about processing methods and GMO crops. Buying organic canola oil can minimize risks.
Nutrition Face-Off: Grapeseed vs. Canola Oil
Let's compare the nutritional profiles of grapeseed and canola oils:
Fat breakdown
- Grapeseed oil - About 70% polyunsaturated fats, 17% monounsaturated fats, and 10% saturated fat
- Canola oil - About 61% monounsaturated fat, 28% polyunsaturated fats, and 7% saturated fat
Vitamins and minerals
- Grapeseed oil - High in vitamin E and plant sterols like beta-sitosterol
- Canola oil - Decent vitamin E plus some vitamin K
Smoke points
- Grapeseed oil - Around 420°F
- Canola oil - Approximately 400°F
Both oils are low in saturated fat and have similar smoke points. Grapeseed oil has more omega-6s, while canola has more monounsaturated fat and omega-3 ALA.
Health Effects: Grapeseed vs. Canola Oil
Here's how grapeseed and canola oil compare in terms of effects on health:
Heart health
In moderation, both oils appear to benefit heart health by improving cholesterol levels and blood pressure. Canola oil may have a slight edge thanks to its omega-3 content.
Diabetes
Early research shows promise for canola oil improving blood sugar control and insulin sensitivity, giving it an advantage for diabetes management.
Inflammation
The omega-3s in canola oil help fight inflammation, while overusing grapeseed oil's omega-6s could promote inflammation.
High heat cooking
With similar smoke points, both grapeseed and canola oil are good options for high heat cooking.
Price
Canola oil tends to be more budget-friendly than pricier grapeseed oil.
For heart health, fighting inflammation, and controlling blood sugar, canola oil appears to have the most benefits. But both are good oils in moderation.
Potential Downsides and Risks
Grapeseed and canola oils have minimal risks when consumed in small amounts. But overdoing oil intake has potential downsides:
- May promote weight gain and obesity
- Risk of lung inflammation and issues if repeatedly heated to high temperatures
- Allergies or intolerance are possible with both oils
- Can become rancid and lose nutritional value when stored improperly
Stick within recommended guidelines of 1-2 tablespoons per day to minimize risks. Moderation is key.
Environmental and Ethical Concerns
Some environmental and ethical factors to consider with grapeseed and canola oils:
- Deforestation - Palm oil is a major cause linked to both oils' production
- Pesticides - Conventional canola crops tend to use pesticides
- GMOs - Most canola and some grapeseeds are genetically modified
- Extraction methods - Hexane solvents are concerning with some canola oil
- Sustainability - Look for local and sustainably produced oil
Choosing organic, non-GMO, locally sourced oils helps reduce environmental impact.
The Bottom Line
When used in moderation, both grapeseed oil and canola oil can be part of a balanced diet. Canola oil's omega-3 content gives it a slight edge for heart health.
Consider factors like production methods, source, and price when choosing oils. Limit oils to 1-2 tablespoons per day and balance with other fats like olive oil.
At the end of the day, grapeseed and canola oil are both vegetable oils with decent nutrient profiles. Focus on whole foods first, enjoy oils in moderation, and find a brand aligned with your values.
FAQs
Is grapeseed or canola oil better for you?
Both oils have benefits, but canola oil's omega-3 content gives it a slight edge for heart health. The oils are comparable in other ways like smoke point and risks.
Which oil has a higher smoke point?
Grapeseed and canola oil have very similar smoke points, around 400-420°F. Both can be used for high heat cooking.
Is canola oil processed?
Yes, commercial canola oil is highly processed using extraction methods and high heat. Seek out cold-pressed, organic canola oil to minimize processing.
Does grapeseed oil promote inflammation?
