The difference between extra virgin and olive oil is that regular olive oil is heated to extract the oil and refined while extra virgin olive oil is cold-pressed and left unrefined. Extra virgin olive oil is usually stronger in flavor and darker in color than regular olive oil.
Extra virgin olive oil is the least processed form of olive oil. Due to this, it retains its natural antioxidants and vitamins, which are often lost during processing. This makes it a more healthful oil than regular olive oil but also makes it a little more expensive.
Use extra virgin olive oil for cooking, in all its varieties. Properly store olive oil, in a dark and tight environment. Start the process by heating the oil over low heat.
The simple answer is yes. If a recipe calls for olive oil, as many do, you can use extra-virgin or regular olive oil. It's up to you, and largely based on personal preference. Both extra-virgin and regular olive oil can be used in baking and cooking, but do keep in mind their differing smoke points.
The quick answer is yes, you can cook with extra virgin olive oil.
Olive oil has a lower smoke point-the point at which an oil literally begins to smoke (olive oil's is between 365° and 420°F)-than some other oils. When you heat olive oil to its smoke point, the beneficial compounds in oil start to degrade, and potentially health-harming compounds form.
It's incredible at absorbing and carrying other flavours, as well as teasing out and amplifying the taste of other ingredients that are cooked in it.
Extra virgin olive oil is the least processed variety and is often considered to be the healthiest type of olive oil. It's extracted using natural methods and standardized for purity and certain sensory qualities, such as taste and smell ( 3 ).
Out of all the different kinds of olive oil available in the market, extra virgin oil is not recommended for cooking.
Olive oil is recommended by the CIA for all methods of cooking. The best, most aromatic extra virgin olive oil (typically most expensive) is recommended for raw/cold usage or used as a finishing condiment.
Some of the world's top celebrity chefs agree that choosing to use genuine extra virgin olive oil in your cooking is a great way to guarantee quality of flavour in your dishes. It is an extremely versatile cooking ingredient and can be used on salads, as a dip, for roasting or for adding finishing touches to hot food.
Even after being opened, refrigeration is not necessary as long as stored properly. However, if you won't be using an opened bottle for several weeks, refrigeration may help preserve the oil until you need it. Just be sure to let it warm to room temperature afterward so that it is completely liquid before using.
Optimum Daily Intake
According to the US FDA, our daily intake of monounsaturated fatty acids should be at least around 17.5 grams, which is about 1.5 tablespoon of extra virgin olive oil. So consume a tablespoon of olive oil daily, instead of cooking with it.
While there is some truth to this (olive oil does appear to cause relatively less damage than saturated animal fats), it is important to note that 'less damage' is still damage. The scientific evidence clearly shows that olive oil plays a role both in damaging blood vessels as well as forming atherosclerotic plaques.
The monounsaturated fats in olive oil offer several health benefits. However, excess consumption of olive oil may cause several side effects. It may cause acne, allergies, skin rashes, blackheads, and saturated- and trans-fat-related diseases. It may also cause diarrhea and inflammation in some people.
Cooking eggs in olive oil will give you better results. The scrambled eggs will have a silky smooth texture, and if you fry them, they will have fine crisp edges. Moreover, olive oil is healthy for your body, giving you another reason to use it over butter.
Olive oil actually has a relatively high smoke point and is a safe, reliable option for frying. On top of that, it is one of the healthiest cooking staples around. Olive oil has been named “the healthiest fat on Earth,” in part because of its unique ability to reduce the risk of heart disease.
A 2019 analysis summarized the findings of 27 studies on the effect of olive oil on cholesterol. It concluded that olive oil consumption decreased total cholesterol, LDL, and triglycerides and increased HDL more than other plant oils.
When you shop for olive oil, be sure to buy extra virgin. It's the only grade that retains its natural phenols (antioxidants) and other health-promoting compounds. Extra virgin olive oil (EVOO) is cold-pressed, meaning it's not extracted using high heat or harsh chemicals.
Bottom line. Extra virgin olive oil is safe for all types of frying and can ramp up the flavor of french fries, sweet potato fries, fish tacos, fried chicken, churros, and more. And while frying isn't the healthiest way to cook, frying with EVOO is just about the healthiest way to do it!
Because it is more expensive than other cooking oils, many people ask us if it can be re-used after frying. The answer is yes, you can reuse olive oil. Researchers conducted a study where food was fried in olive oil and found that olive oil was stable even when reused 10 times.
This is because deep-frying needs to hit a temperature that is on the borderline of the smoke point of extra virgin olive oil. When reached, it will produce an unpleasant, burnt flavour that will taint any food you are cooking.
Use olive oil to stir-fry or sear a steak.
Though it's nice to have two oils (one for cooking, such as canola oil, and one for finishing, such as extra-virgin olive oil), here's a secret: We use extra-virgin olive oil for high-heat applications, too. And it's completely fine.
Virgin olive oil contains numerous phenolic compounds that exert potent anti-inflammatory actions. Of interest to this paper is the recently discovered phenolic compound oleocanthal. Oleocanthal is contained in virgin olive oil and possesses similar anti-inflammatory properties to ibuprofen.
