king of the cooking oils
Which oil is the best? It's a very subjective topic, but let's look at the specifics before making that judgment call.
Let's look at the pros and cons of each one:
Vegetable & Seed Oil
Sunflower Oil - light flavour, good for frying
Canola Oil - neutral taste, versatile, budget-friendly
Soybean Oil - widely used in processed foods
Corn Oil - high smoke point, ideal for deep frying
Vegetable Oil (blend) - mixed oils, general purpose
Pros: Many are rich in saturated fats, especially polyunsaturated fats (PUFAs)
Can help lower LDL ("bad") cholesterol when replacing saturated fats like butter
Widely supported in moderation by organisations like the American Heart Association
High smoking points like canola, sunflower and soybean handle heat high heat well
Ideal for frying, roasting and sauteing without burning quickly
Affordable and widely available, much cheaper than oils, like olive and avocado
Neutral taste, doesn't overpower food, good for baking and general cooking
Cons:
Often extracted using chemicals (e.g. hexane and high heat)
Process may reduce nutrients and create oxidation by products
Very high in Omega-6 (fatty acids) which can lead to inflammation (still debated)
Fruit Based Oils
Olive Oil - Rich in monounsaturated fats (heart-healthy)
Avocado Oil - very high smoke point, great for searing
Coconut Oil - distinct flavour, common in baking & Asian dishes
Palm Oil - used in processed foods (less common for home cooking in some regions)
Pros:
Rich in monounsaturated fats (heart-healthy)
Contains antioxidants
Best for low to medium heat, salads, and sauteing
One of the healthiest and most respected oils. Why? Let's dig deeper:
The monounsaturated fats is very high (70-75%) and, crucial polyphenol antioxidants.
It also reduces harmful LDL, cholesterol, fights inflammation, and is linked to lower risks of heart disease and chronic illnesses, making it a cornerstone of a healthy heart- protective diet.
Cons:
While olive oil is highly stable, it has specific downsides when used for cooking, ranging from cost and flavour profile to the potential loss of delicate nutrients. Heat of 350-400 F can degrade some of the beneficial antioxidants and vitamin E that make extra virgin olive oil so healthy.
If cooking, bear in mind the heating requirements, as it will lose some of its nutrients.
Extra Virgin vs Other Oils
For maximum health benefits, opt for cold-pressed extra virgin olive oil rather than refined or standard olive oil.
Nut Oils
Peanut Oil- Almond Oil- Walnut Oil - Hazelnut Oil- Macadamia Oil -Pecan Oil -Brazil Nut Oil
Some (like peanut oil) are widely used for cooking due to higher heat tolerance.
Other (like walnut or pistachio oil) are best for dressings and finishing
Pros:
Rich in healthy fats (High in unsaturated and especially in MUFA) and sometimes omega-3s (especially walnut oil)
Can support heart health when replacing saturated fats
Often compared favourably to extra virgin olive oil
Nutrient-Dense (vitamin E, antioxidants, and plant compounds)
Less processed (especially cold-pressed varieties) than many seed oils
Has a nutty, distinct taste which is tasty; it enhances salads, dressings and finishing dishes
Cons:
Low smoke points, many burn easily (like walnut and flaxseed)
Not ideal for frying or high-heat cooking
Better for drizzling or low-heat use
Expensive, much pricier than vegetable or seed oils
Shorter shelf life adds to the cost over time
Can spoil quickly (exposed to heat/light, stored too long, often need refrigeration after opening
Not safe for people with nut allergies (especially peanut, almond oils, depending on refinement)
Based on People Demand, here is the best overall:
1) Olive Oil (especially extra virgin)
Why? Rich in MUFA, high in antioxidants, high in heart health
2) Avocado Oil
Why? Similar fats to Olive Oil (MUFA-rich), very high smoking point, neutral taste
3) Nut Oils (Walnut, Almond, Macadamia)
Why? Nutrient-Dense, some omega-3s (walnut), less processed (often cold-pressed), great taste
4) Seed & Vegetable Oils
Why? Neutral, middle ground taste, cheap, versatile, good for high heat
5) Tropical Oils (Coconut Oil, Palm Oil)
Why? Very stable for cooking, long shelf life
