Avocado Oil, Coconut Oil, or Olive Oil? Which Cooking Oil Is The Best Choice for Cooking and Health?

by | Jan 8, 2025 | Health, Nutrition | 0 comments

When it comes to deciding which oil to use on the pan when cooking meals at home there are many different options. Some people use canola oil, some swear by butter. However when it comes to my kitchen operations I usually stick with a select three or four depending on what I’m preparing. Plant-based oils are staples in many kitchens, prized for their versatility and health benefits. Among the most popular are avocado oil, coconut oil, and olive oil. Each has its unique characteristics, nutritional profile, and ideal cooking applications. But which is the healthiest and safest for various cooking temperatures? Let’s dive into the science to help you make a well informed decision.

1. Avocado Oil

Overview:

Avocado oil is made by pressing the pulp of the avocado fruit. It is rich in monounsaturated fats, particularly oleic acid, which is linked to heart health and anti-inflammatory benefits.

Smoke Point:

Refined: 520°F (271°C)

Unrefined: 375°F (190°C)

Health Benefits:

  • High in antioxidants, particularly lutein, which supports eye health.
  • Promotes heart health due to its monounsaturated fat content.
  • Contains Vitamin E, which aids skin health and acts as an antioxidant.

Additional Studies:

  • Avocado oil and cholesterol: A study found that avocado oil’s high concentration of oleic acid can reduce low-density lipoprotein (LDL) cholesterol levels without lowering high-density lipoprotein (HDL) cholesterol or triglycerides. 
  • Avocado oil and liver metabolism: A study found that avocado oil improved the activity of the ETC in liver, brain, and kidney mitochondria in diabetic rats.
  • Avocado oil and renal damage: A study found that avocado oil prevented renal damage, mitochondrial dysfunction, and oxidative stress in the kidneys of hypertensive rats.
  • Avocado oil and NMR spectroscopy: A study used high-resolution 1H-NMR to characterize and assess avocado oil. 
  • Avocado oil and thermal behavior: A study found that avocado oil fortified with methanol or ethyl ether extracts had a protective effect against the production of secondary oxidation compounds. 
  • Avocado oil and carotenoid absorption: A study found that avocado oil enhances the absorption of carotenoids from salad and salsa by humans. 

Other studies have shown that avocado oil can: Help control weight, Reduce the risk of diabetes, Normalize blood cholesterol levels, and Help in skin care. 

Best Uses:

High-temperature cooking like frying, roasting, or grilling.

Salad dressings and dips when using unrefined varieties for a buttery flavor.

2. Coconut Oil

Overview:

Coconut oil is extracted from the meat of coconuts and is primarily composed of saturated fats, specifically medium-chain triglycerides (MCTs), which are metabolized quickly for energy.

Smoke Point:

Refined: 400°F (204°C)

Unrefined (Virgin): 350°F (177°C)

Health Benefits:

  • MCTs may promote weight management by enhancing satiety and energy expenditure.
  • Has antibacterial and antimicrobial properties due to its lauric acid content.
  • May improve cholesterol levels by raising HDL (“good” cholesterol).

Additional Studies:

  • Cardiovascular health: Meta-analyses of randomized clinical trials (RCTs) suggest that coconut oil doesn’t improve cardiovascular health or lipid parameters. However, a randomized study found that coconut oil didn’t change cardiovascular risk factors or events over two years. Another study found that coconut oil may have less detrimental effects on LDL-cholesterol than butter, but not compared to vegetable oils. 
  • Blood lipids: A randomized trial found that coconut oil and butter had different effects on blood lipids than olive oil, but coconut oil was more similar to olive oil than butter. 
  • Antibacterial properties: Coconut oil may reduce harmful bacteria in the mouth, and lauric acid in coconut oil may help prevent cavities and reduce plaque buildup. However, more research is needed.
  • Cooking: Coconut oil is stable for cooking because it resists oxidation and polymerization. It’s suitable for shallow frying, but not for deep-frying because it has a low smoke point. 

Best Uses:

Baking or low- to medium-heat cooking.

Adds a subtle coconut flavor to dishes when using virgin coconut oil.

3. Olive Oil

Overview:

Olive oil, especially extra virgin olive oil (EVOO), is celebrated for its rich polyphenol content and is a cornerstone of the Mediterranean diet.

Smoke Point:

Extra Virgin: 375°F (190°C)

Refined: 465°F (240°C)

Health Benefits:

  • Packed with antioxidants and polyphenols, which reduce oxidative stress.
  • Linked to reduced risk of heart disease, thanks to its monounsaturated fats.
  • Anti-inflammatory properties help combat chronic diseases.

Best Uses:

Low to medium-heat cooking like sautéing.

Excellent for salad dressings, marinades, and drizzling over finished dishes.

Comparing Health Benefits and Safety at Different Temperatures

Which Oil is the Best?

For High-Heat Cooking:

Avocado oil is the winner. Its high smoke point and nutrient stability make it the best choice for frying and grilling without compromising health.

For Low- to Medium-Heat Cooking:

Olive oil shines here, especially extra virgin varieties. Its rich polyphenol content adds nutritional value to every dish.

For Baking or Special Diets:

Coconut oil is ideal for recipes requiring solid fat or those following ketogenic diets, but its saturated fat content should be consumed in moderation.

Conclusion

The healthiest oil ultimately depends on your daily or weekly cooking needs. Avocado oil provides versatility for high-heat cooking, olive oil offers unparalleled health benefits for lower temperatures, and coconut oil serves as a flavorful option in specific contexts. By choosing the right oil for the task, you can maximize flavor while protecting your overall health. Ultimately the choice is yours!
