What are the advantages of olive oil for health?

Olive oil is an essential ingredient in the Mediterranean diet, and it is high in antioxidants. The most important fat it contains is monounsaturated fats (MUFAs), which experts regard as healthy fat.

The antioxidants found in olive oil can aid in protecting the body from cellular damage, which could cause a wide range of diseases and health conditions. Olive oil that is extra virgin can have a bitter taste; however, it has more antioxidants than the other types because it is subject to the most minimal processing.

The article below will learn more about the advantages of olive oil’s health benefits and discover some tips about how you can make use of it.

What is olive oil?

Olive oil is derived from the olives, the fruits from the tree of olives. Olives are a staple product in the Mediterranean region. The process of making olive oil involves pressing whole olives.

Olive oil is widely used for cooking, cosmetics, soaps, medicine, and even as a fuel source to traditional light candles. Olive oil originated from the Mediterranean; however, today, it is widely used around the globe.

In the food chain, people preserve olives in the form of olive oil or in salted water. They eat them whole or chopped for pizzas and then add them to other meals.

It can be used to dip pieces of bread and pasta for drizzles for cooking, or for salad dressing. People take it in spoonfuls to aid in healing.


Numerous studies have examined the advantages of olive oil to health. Olive oil that is extra virgin, the top quality oil available, is rich in antioxidants that can help protect against cell damage caused by free radicals.

Free radicals are the substances that Trusted Source produced by the body in the course of metabolism and other processes. Antioxidants neutralize free radicals.

If there are too many free radicals are created, they may create oxidative stress. This can lead to cell damage, and it may play a role in the development of certain diseases, including certain types of cancer.

Olive oil and cardiovascular system

Olive oil is the main Source of fat in the Mediterranean diet. People who adhere to this type of diet are believed to have longer longevity, as well as a lowered risk of dying from cardiovascular disease, in comparison to those who adhere to other diets. According to some experts, the Trusted Source calls it “the most effective preventive medical treatment.”

A 2018 study 2018 examined the prevalence of heart attacks among those who followed the Mediterranean diet, whether with nuts or olive oil or a diet with low fat.

The people who ate those who ate the Mediterranean diet, either that was with nuts or olive oil, had lower rates of heart disease than those who ate the diet with low fat.

As per the writers of a review from 2018 according to one review in 2018, the Food and Drug Administration (FDA), as well as the European Food Safety Authority, recommend eating around 20 grams (g) or 2 spoons (tbs) from extra virgin olive oil per daily to lower the risk of developing cardiovascular illness as well as inflammation.

The results of the 2017 study by the Trusted Source found that polyphenols found in olive oil could provide protection against cardiovascular disease, atherosclerosis, stroke and brain dysfunction, and cancer. Polyphenols are a kind of antioxidant.

Metabolic syndrome

Metabolic syndrome is a condition characterized by a group of risk factors that increase disease risk, including obesity and high blood pressure and elevated blood sugar.

The authors of a meta-analysis in 2019 found that olive oil as part of the Mediterranean diet may improve symptoms of metabolic syndrome such as blood sugar levels, inflammation, triglycerides (fats in the blood), and low-density lipoprotein (LDL) or “bad” cholesterol. However, it is believed to increase the levels of the high-density lipoprotein (HDL), which is known as “good” cholesterol.

The risk of depression and olive oil

In 2013, a rodent study trusted Source suggested that ingredients in extra virgin olive oil may help protect the nervous system and could be useful for treating depression and anxiety.

A few years prior, scientists had discovered evidence that those who consumed trans fats and unhealthy fat found in fast food and ready-to-eat baked products were more likely to suffer from depression than those who ate unsaturated fats, like olive oil.

Olive oil and the risk of cancer

Certain studies conducted by Trusted Source have suggested that certain substances in olive oil can lower the chance of breast cancer; however, there aren’t any studies that confirm this.

According to research conducted by Trusted Source published in the year 2019, Olive oil is a source of substances that may aid in the prevention of the development of colorectal cancer. Tests in the lab have revealed that antioxidants found in olive oil could help to protect the body from oxidative damage, inflammation, and epigenetic modifications.

Alzheimer’s disease

In 2016, researchers claimed that adding olive oil from extra virgin olives in your diet could help in the prevention of Alzheimer’s disease. This could be due to its ability to protect blood vessels within the brain.

The authors of the research study on mice published in 2019 concluded that eating extra virgin olive oil containing oleocanthal can slow down or stop the progress of Alzheimer’s disease. Oleocanthal is a phenolic chemical that is found in extra virgin olive oil.

The liver and olive oil

A review of lab research found that the molecules present in olive oil extra virgin could help in preventing or repairing damage to the liver.

The oil’s MUFAs that consist mainly of oleic acid and its phenolic components appear to reduce inflammation and oxidative stress, insulin resistance, and other changes that could lead to liver damage.

The olive oil in the form of olive oil can cause inflammatory bowel diseases.

Inflammatory digestive bowel disease (IBD) is a cause of inflammation in the digestive tract. Ulcerative colitis and Crohn’s disease are both types of IBD.

A review published in 2019 by a review published by Trusted Source found that phenols present in olive oil can help improve the immune system and improve gut health by altering the gut microbes. This may be beneficial for those suffering from colitis as well as other forms of IBD. The authors pointed out that more human studies are required to confirm the results.


As per the United States Department of Agriculture (USDA)Trusted Source 1 tbsp equivalent to 13.5 grams (g) of olive oil, contains:

  • 119 calories
  • 13.5 grams of fat, of which 1.86 grams are saturated
  • 1.9 milligrams (mg) of vitamin E
  • 8.13 micrograms (mcg) of vitamin K

It also contains traces of calcium and potassium in addition to asTrusted Source polyphenols phytosterols, tocopherols and tocopherols squalene, terpenic acids as well as other antioxidants.

Food tips

When purchasing olive oil, it is recommended to purchase the extra-virgin olive oil because it undergoes less processing and will be more likely to keep its antioxidants. The extra-virgin olive oil is characterized by a very high smoke point of 376 degrees (191degC) which means it is safe for all cooking methods.

It is the USDA grade olive oil is graded by USDA according to its flavor, aroma, and the absence of defects and acidity.

U.S. Extra Virgin Olive Oil (EVOO) It has a wonderful taste and smell, and it has a free fatty acid level of 0.8 grams or less for 100g (0.8 percent).

U.S. Virgin Olive Oil: This is a decent aroma and flavor, as well as it has a free fatty acid level of less than 2g for 100g (less than 2.2%).

U.S. Virgin Olive Oil Not Fit for human consumption without further processing It is a virgin oil with a bad flavor and smell. It’s not intended to be used in food preparation.

U.S. Olive Oil: It is an oil mixture that contains refined and virgin oils.

U.S. refined Olive Oil: This is an oil that is made from refined oils that have some limitations on processing.

These labels have been made not mandatory. Producers are not required to label their products.

In several countries, such as the U.S., manufacturers process “light” or “extra light” olive oils by heating and chemicals to remove impurities. The flavor and color are more subtle compared to olive oils that are virgin. Producers might mix lighter olive oils with different oils.

Tips for use

Some tips for using olive oil are:

  • drizzle it over the salad or make it a part of the dressing for salads
  • drizzle it over a freshly baked loaf of bread
  • Making bread using it
  • Utilizing it in place of other oils when you fry or sautéing

Try these dishes:

  • Crisp rosemary and flatbread with olive oil
  • Spaghetti with chili, olive oil, and garlic
  • Poor man’s potatoes

Frying in olive oil

According to a review by Trusted Source that was published last year, cooking foods in olive oil could aid in maintaining and improving the nutritional value of food. This is because food is able to absorb antioxidants which are released into the oil.

Olive oil is sold in grocery stores as well as online.

Question: I have discovered the idea that heating olive oil alters its chemical composition, making it harmful. Does this sound true?

Answer: It is a popular mistake. Research has proven that olive oil that is extra-virgin has a high smoke temperature at 376degF (191degC), which makes it safe for use in all cooking techniques, such as cooking.

But, if you fry using olive oil for an extended duration, this could cause the degradation of fats and the creation of harmful compounds, such as Acrolein. Acrolein is a highly reactive, toxic substance that could cause cell damage when it is swallowed. Therefore, as it is used in conjunction with olive oil to saute or fry and avoid frying for long periods, it’s healthy.

A few studies have shown that pan-frying foods like onions, tomatoes, or garlic with olive oil enhance the bioavailability of phytochemicals, like carotenoids as well as polyphenol antioxidants. So, cooking with olive oil could improve the nutritional value of your food.
