Olive oil has been used for cooking for thousands of years. It is a cornerstone of the Mediterranean diet. So why do some people today believe that olive oil shouldn't be used for cooking? One persistent rumor is that olive oil will reduce its health benefits when heated. This rumor is false. Here's why:
First, olive oil's main health benefit is its fat composition. Olive oil is mostly monounsaturated fat. Cooking with an oil will not change its fat composition. Olive oil's percentage of monounsaturated fat remains the same after heating, even to elevated temperatures.
According to the American Heart Association, monounsaturated fats can help reduce bad cholesterol levels in your blood which can lower your risk of heart disease and stroke. They also provide nutrients to help develop and maintain your body's cells.
The Food and Drug Administration (FDA), in 2004, approved a health claim for olive oil on the basis that the monounsaturated fat in olive oil may reduce the risk of coronary heart disease when used in place of saturated fat.
All olive oils, whether extra virgin or refined, heated or raw, contain a comparable amount of monounsaturated fat.
Cooking oils, when heated, may form small amounts of trans fats. However, the concentration is minuscule -- less than 1 percent - even with lengthy heating.
All olive oil has relatively high smoke point (between 365 and 410 F) that is generally not impacted by household cooking. But smoke point is not the most important factor when evaluating a cooking oils suitability for cooking. The essential issue in comparing oils is oxidative stability--the extent to which a cooking oil resists breaking down under heat, which may result in the formation of potentially harmful compounds.
Research has found that extra virgin olive oil is the most stable cooking oil under heat when it comes to the production of polar compounds, outperforming cooking oils that have a higher smoke point. One reason for this is that olive oil contains phenols and antioxidants that protect it from breaking down when heated.
Another important factor is the fatty acid composition of the oil (monounsaturated fats like olive oil resist oxidation better than polyunsaturated fats like soy and corn).
And another important factor appears to be the extent to which the oil has already been subjected to high heat by refining (most other commercially available cooking oils such as canola, soy, corn, sunflower, etc.) have been refined in the manufacturing process, unlike EVOO that has not been refined.
This new research is consistent with a 2004 study in which measured potentially harmful aldehydes generated when extra virgin olive oil, olive oil and canola oil were heated to 464°F. The study found that both extra virgin and regular olive oil performed better than canola oil, although canola oil ha a higher smoke point.
Furthermore, it is not probable that you will transcend the smoke point of olive oil when cooking. Stovetop cooking does not usually 350ºF, even if you turn the burners to high and even if you turn up your oven to 450ºF, the food and oil does not reach that temperature.
You may have also heard that you should not cook with olive oil because the phenols will be ruined by the heat--this is also not correct. It is a fact that phenols in olive oil are sensitive to heat. But a 2015 study made a remarkable discovery. When cooking with extra virgin olive oil, the phenols move into the food. Potatoes fried in EVOO contained more phenols and antioxidants than potatoes boiled in water.
Furthermore, a 2020 study by the University of Barcelona in the Journal Antioxidants confirmed that extra virgin olive oil retains significant amounts of these healthy compounds during cooking.
The flavor compounds in olive oil are delicate and will evaporate when heated. Heating olive oil does not damage the health benefits but it will make the olive oil shed some flavor. Some folks believe this to be a good thing as they do not want their foods to taste like olive oil. But if you have an expensive olive oil with complex flavors, you may want to save it for finishing and cold uses.
In summary, olive oil is safe to cook with. Heating olive oil will not destroy the health benefits or turn olive oil unhealthy. You can feel confident using olive oil in all of your recipes.
True 100% Extra Virgin Olive Oil is a mild and delicate addition to many wonderful dishes, and it is also one of the most health-promoting types of oils available. Olive Oil is very rich in monounsaturated fat; a type of fat that researchers are discovering has exceptional health benefits.
No other naturally produced oil has as large an amount of monounsaturated fat as Olive Oil -mainly oleic acid. Additionally, the olive contains a high quantity of polyphenols and antioxidants, including hydroxytyrosol, oleuropein, and tyrosol.
To preserve these beneficial qualities, it is essential to press the olive as close as you can to the time it was harvested from the tree. All of our oils have been pressed in an astonishing 3-4 hours from the time of harvest!
As the greatest example of monounsaturated fat, Olive Oil is a quality part of the broadly researched Mediterranean Diet. Olive Oil is a natural juice, that preserves the taste, aroma, vitamins and properties of the olive fruit.
Olive Oil is the only oil that can be consumed as it is, in its own natural state, freshly pressed from the fruit! All other oils are chemically processed, refined, and/or chemically extracted.
Arteriosclerosis: It has been proven that olive oil has an effect in preventing the formation of blood clots. It has been observed that by avoiding excess blood coagulation, olive-oil-rich diets can satisfy the effect of fatty foods by decreasing blood clot formation, thus contributing to the low incidence of heart failure in states where Olive Oil is the principal fat absorbed.
Cholesterol: Olive Oil lowers the levels of total blood glucose, LDL-cholesterol and triglycerides. At the same time it does not alter the levels of HDL-cholesterol (and may even raise them), which plays a protective function and prevents the formation of fatty patches, thus stimulating the elimination of the low-density lipoproteins.
Olive Oil appears to have a favourable effect on bone calcification, and bone mineralization is better the more olive oil is absorbed. It helps calcium absorption, thereby playing an important part during the period of development and in the prevention of osteoporosis.
Vitamin E (alpha-tocopherol), carotenoids and phenolic substances are all antioxidants whose activity has been demonstrated in many studies, revealing further advantages in the prevention of certain diseases and also of ageing.
Extra Virgin Olive Oil is particularly rich in these substances and it has a powerful antioxidant effect, protecting against damage from free radicals and against the formation of cancer.
Olive Oil is a nutrient of great biological value. Like all other fats and oils it is full of calories (120 to 130 calories in 1 tablespoon of 15ml). However, experience demonstrates that there is less obesity amongst the Mediterranean people, that consume the most Olive Oil.
It has been demonstrated that an olive-oil-rich diet leads to greater and longer-lasting weight loss than a low-fat dietplan. It is accepted better because it tastes good and it is a stimulation to eat vegetables.
Olive Oil plays a key role in fetal development during pregnancy and a shortage may have adverse effects on the baby's subsequent development. It has been demonstrated that the post-natal development of babies of mothers who consumed Olive Oil when pregnant is better in terms of height, weight, behaviour and psycho-motor reflexes.
The fetus needs vitamin E to grow. The newborn baby also needs a store of vitamin E to fight against the oxidative stress caused on entering an air atmosphere. Although not quite abundant in Olive Oil, it is present in sufficient quantity thanks to the resistance of Olive Oil to oxidation.
Therefore, both the amount and the kind of food consumed in the diet during pregnancy play a key part in the metabolic adaptations that occur in the mother and in her functional relationship with her fetus.
Made from Trebbiano and/or Lambrusco grapes, balsamic vinegar is well known for its rich flavor and velvety black color. It is fermented in various kinds of wooden barrels, much like wine, and the taste of balsamic vinegar intensifies the longer it is aged.
The thicker and more intense the flavor becomes, the less you need to use to supply a taste boost. Balsamic vinegar offers a number of health benefits, though the serving size is small. The health benefits of balsamic vinegar are extensive and popular among health communities. Here are just a few reasons to use balsamic vinegar for its nutritional value.
Balsamic vinegar is packed with antioxidants which help prevent chronic illnesses and boosts the immune system. It also helps destroy free radicals in the body to protect the cells from destruction.
In a 2010 study published in the "Journal of Nutritional Science and Vitaminology," findings state that polyphenols found in balsamic vinegar stop the oxidation of LDL cholesterol that blocks arteries that cause clogging and hardening. Since balsamic vinegar is also low in cholesterol, it can reduce the risk of heart attacks.
According to a study published in "Medscape General Medicine" in 2006, researchers found that balsamic vinegar reduced the hardening of arteries, also known as atherosclerosis. The vinegar is also low in sodium, which reduced blood pressure levels to enhance heart health, according to Natural News.
Because of this, balsamic vinegar also lowers and stabilizes blood pressure levels. Researchers in the study found that those who regularly consumed vinegar exhibited lower systolic blood pressure levels. However, further study on humans is required, as this study was initially animal-based.
1 tablespoon of balsamic vinegar offers only 10 calories. The vinegar also improves metabolism since polyphenols found in the vinegar breaks protein down into smaller amino acids.
With balsamic vinegar, a little goes a long way. Use 1 tablespoon or not when adding balsamic vinegar to salad dressings, sauces or even soups.
The same size serving also contains a minimal amount of fat and less than 3 grams each of carbohydrates, including sugar. Aside from its ability to enhance metabolism, balsamic vinegar also has the ability to suppress the appetite. Since the vinegar also uses calories from grapes' sugar content, it is a great alternative to fatty dressings full of mayonnaise.
Balsamic vinegar is low on the glycemic index, which allows people to feel full for a longer period of time. Studies show that eating three to four tablespoons of balsamic vinegar daily can also enhance insulin sensitivity, which can lead to better diabetes control.
Balsamic vinegar improves digestion as it contains polyphenols, which encourage pepsin enzyme activity in the body. The digestive enzyme pepsin stimulates protein break down into amino acids to assist the intestines in absorbing the amino acids.
