The Hidden Mystery Behind Olive Oil
n annual international symposium on olive oil and health hosted by the Yale School of Public Health is heading to the center of the olive oil world - Spain top experts will meet in the coming months to study the potential and impact of what is sometimes referred to as "liquid gold."

Co-hosted by the University of Jaen, the symposium will run from December 9 to 12 in Jaen, a city in the province of Andalusia which is the center of Spain's olive oil belt and an area that is being considered as a UNESCO World Heritage site for an olive grove, known as the Mar de Olivos, or "Sea of Olives." This is the third symposium that has been held in 2018. The previous year's symposium was delayed due to the epidemic.

The event was organized with Vasilis Vasiliou, Ph.D., the Susan Dwight Bliss Professor of Epidemiology and the chair of the Yale School of Public Health's Department of Environmental Health Sciences, along with Tassos C. Kyriakides, Ph.D. Tassos C. Kyriakides, Ph.D., Yale Center for Analytical Sciences (biostatistics) faculty member. The symposium will bring participants from business, academia farmers, national and regional decision makers to explore the untapped opportunities of the Olive tree as well as its fruits including olive oil.

"We're thrilled to return. This year's event will be the largest yet, and features an amazing and exciting program. I am incredibly excited about bringing together so many people who are as obsessed with olive oil like I am." declared Vasiliou. "There's no other gathering anywhere else in the world."

The symposium of this year will cover diverse topics that are central to the cultivation of olives as well as what the next steps for olive oil for both human and planet health. The topics include:

Recent studies have revealed improvements in health associated with olive oil.
How climate change is impacting olive groves and how the cultivation of olives can positively affect the climate.
Successful olive oil marketing along with business strategies.
Each program session will conclude in a panel discussion and an open-ended Q&A. The symposium will also feature the opportunity to taste olive oil and an educational tour through the olive groves.

The Yale School of Public Health is seeking to launch an institute called the Yale Institute for Olive Sciences and Health, which would be devoted to the study of the olive tree, its fruits and their derivatives, and ways to further integrate the fruit and its components into the diet of people. The institute will also concentrate on planetary health issues such as sustainability, circular economy models and climate change.

Vasiliou, who is from Greece as well as a major center of olive oil production as well as an important consumer, suggested that a proposal to establish an olive oil institution needs to be completed and put up for review before the year's end. This institute would function as a global institution that would facilitate and oversee research in all fields related about the oil tree, its fruits and products.

There's nothing like this conference anywhere else in the world.

Vasilis Vasiliou
"I grew up with olive oil and have seen its benefits firsthand. Mediterranean nutrition has been recognized for a long time as the most healthiest in the world, and its cornerstone is olive oil." he added. "I want to help establish the Yale School of Public Health's collaborative leadership in this crucial area."

In the meantime, Kyriakides, an olive oil sommelier not only always is tasting oils from around the world, he takes in large quantities of olive oil every day for his cooking, in addition to his daily morning additional virgin olive oil drink.

"It works for me and is delicious and healthfully nutritious," he said. "The olive tree and olive oil have connected individuals for centuries. it's our job as public health professionals to ensure the benefits that this superfood may bring to the health of humans are shared with the people we interact with."

The research of the past 50 years indicates that olive oil can promote healthy health, Kyriakides said. A daily consumption that is 20g of olive oil (about two tablespoons) that includes a certain amount of a certain polyphenol (at least 5 mg of hydroxytyrosol as well as its derivatives) has a health benefit, approved by the European Food Safety Agency and the U.S. Food and Drug Administration and is related to the protection of blood fats from oxidative stress.

Spain, which requested to be the co-host for this year's symposium is the largest producers of olive oil around the globe, accounting for 35% - 40% of the output, Kyriakides said. Furthermore, many of the innovations in the area of olive agriculture, as well as sustainability and environmental health initiatives have come out of Spanish practices.

"Now more than ever before, the need for such an internationally focused institute is so apparent in our efforts to develop healthier, more environmentally sustainable methods that will improve both our human and global wellbeing," Kyriakides said.

The health benefits of eating fat are controversial.

However, experts agree that olive oil -- especially extra virgin -is healthy for your health.

Here are 11 health benefits of olive oil, which are backed by research conducted in the field of science.

1. Olive Oil Is Rich in Healthy Monounsaturated Fats

Olive oil is the natural oil extracted from olives, the fruit of the olive tree.

About 14% of the fat is saturated fat and 11% are polyunsaturated such as omega-6 and omega-3 fatty acids ( 1).

However, the primary fatty acid present in olive oil is the monounsaturated fat known as Oleic acid, which accounts for 73 percent of the oil content.

Studies suggest that oleic acids reduce inflammation and may even improve the function of genes linked to cancer ( 2Trusted Source, 3Trusted Source, 4Trusted Source, 5Trusted Source).

Monounsaturated fats can also be resistant to high heat which makes olive oils that are extra-virgin an healthy option for cooking.

DescriptionOlive oil is high in monounsaturated Oleic acid. This fatty
Acid is believed to have many beneficial effects and is a healthy choice for
Cooking.

2. Olive Oil Contains Large Amounts of Antioxidants
Extra virgin olive oil is fairly nutritious.

Apart from its beneficial fatty acids it is also a good source of vitamins E and K.

But olive oil is also packed with potent antioxidants.

They are biologically active, and could reduce your risk of chronic illnesses ( 6Trusted Source, 7Trusted Source).

They also fight inflammation and help to protect your blood cholesterol from oxidation, two advantages that can reduce your risk of suffering from heart illness ( 8Trusted Source, 9Trusted Source).

Summary
Extra virgin olive oil is brimming with antioxidants,
some of which have powerful biological effects.

3. Olive Oil Has Strong Anti-Inflammatory properties
Chronic inflammation is believed to be the primary cause of many diseases, including heart disease, cancer, metabolic syndrome and type 2 diabetes arthritis, Alzheimer's and obesity.

Extra-virgin olive oils can lower inflammation, which may represent one of the main factors behind its health benefits.

The most significant anti-inflammatory properties are produced through antioxidants. The most important of them is oleocanthal, which has been shown to work like ibuprofen which is an anti-inflammatory medication ( 10Trusted Source).

Some scientists estimate that the oleocanthal in 3.4 tablespoons (50 ml) from extra-virgin olive oil has similar effects to 10% of the adult dosage of ibuprofen ( 11Trusted Source).

The research also suggests that oleic acid, the main fatty acid of olive oil could reduce levels of important inflammatory markers such as C-reactive protein (CRP) ( 2Trusted Source, 3Trusted Source).

Another study showed that antioxidants in olive oil may inhibit some genes and proteins which cause inflammation ( 12Trusted Source).

Summary
Olive oil is rich in the nutrients needed to fight
inflammation. This includes the oleic acid and the antioxidant oleocanthal.

4. Olive Oil May Help Prevent Strokes
The cause of stroke is a disruption in the flow of blood to your brain because of bleeding or a blood clot.

In developed countries stroke is most frequent cause of death, right after coronary heart diseases ( 13).

The connection between olive oil consumption and risk of stroke has been investigated thoroughly.

A huge review of research of 841,000 individuals found an olive oil to be the only source of monounsaturated fats that is associated with a lower risk of heart and stroke diseases ( 14Trusted Source).

In another study that included 140,000 participants, those who ate olive oil significantly less at risk of having a stroke than those who did not ( 15Trusted Source).

Summary

people who consume olive oil have a much lower risk of stroke, which is the second biggest
killer in developed countries.

5. Olive Oil Is Protective Against Heart Disease
Heart disease is the most common cause of death in the world ( 16).

Observational studies conducted a few decades ago showed that heart disease is uncommon in Mediterranean countries.

This has led to extensive research on the Mediterranean food plan, which has now been shown to significantly reduce the risk of heart disease ( 17Trusted Source, 18Trusted Source).

Olive oil that is extra virgin and unrefined are among the most important ingredients in this diet plan, which protects from heart diseases in a variety of ways ( 19).

It reduces inflammation, shields "bad" LDL cholesterol from oxidation, and improves the blood vessels and may help prevent excessive blood clotting (20Trusted Source 21Trusted Source, 22TrustedSource 23Trusted Source, 24Trusted Source, 25Trusted Source).

Interestingly, it has also been proven to reduce blood pressure which is among the biggest risk factors associated with cardiovascular disease as well as premature deaths. One study found that olive oil was found to reduce the need to take blood pressure medications by 48% ( 26Trusted Source, 27Trusted Source, 28Trusted Source).

Dozens, if not hundreds of research studies show that extra-virgin olive oil is a powerful source of benefits for your heart.

If you have heart disease, a family record of the disease or any other risk factor, you might be able to incorporate lots in extra virgin olive oils into your diet.

Summary
Olive oil extra virgin offers many advantages
to maintain to improve heart health. It lowers blood pressure, helps protect "bad" LDL cholesterol
particles from oxidation and enhances the blood vessels' function.

6. Olive Oil Does Not Have a Connection With Weight Gain and Obesity
Eating excessive amounts of fat can cause weight growth.

But, numerous studies have found that studies that have linked Mediterranean diet, which is rich in olive oil with favorable results on weight loss ( 29Trusted Source, 30Trusted Source, 31Trusted Source).

In a study of 30 months involving more than 7,000 Spanish college students, eating lots of olive oil wasn't linked to weight gain ( 32Trusted Source).

Additionally, one three-year study in 187 participants found that a diet high in olive oil led to increased levels of antioxidants found in the blood, as well as weight reduction ( 33Trusted Source).

Summary
Consuming olive oil does not seem to
boost the chances of the likelihood of weight gain. Moderate intake may even aid the process of losing weight.
loss.

7. Olive Oil May Fight Alzheimer's Disease
Alzheimer's disease has been identified as the second most prevalent neurodegenerative disease in the world.

One of its key features is the formation of beta-amyloid plaques within your brain cells.

A study on mice revealed that a compound found in olive oil may help to remove the deposits ( 34Trusted Source).

Furthermore, a study of humans found that an Mediterranean diet rich in olive oil helped improve brain function ( 35Trusted Source).

Keep in mind that there is a need for more research regarding the effects of olive oil on Alzheimer's disease.

Summary
Certain research suggests that olive oil may
combat Alzheimer's disease, but it is imperative to conduct more research.

8. Olive Oil May Reduce Type 2 Diabetes Risk
Olive oil is believed to be a powerful protector against type 2 diabetes.

OlioCru have linked olive oil to benefits on blood sugar and an increase in insulin resistance ( 36Trusted Source, 37Trusted Source).

A controlled clinical trial randomized in 418 healthy adults recently confirmed the beneficial effects that olive oils have on health ( 38Trusted Source).

In OlioCru was found that a Mediterranean diet rich in olive oil decreased the risk of Type 2 Diabetes by more than 40%..

Summary
Both clinical and observational studies.
trials show that olive oil when paired with trials suggest that olive oil, in conjunction with a Mediterranean diet, can help to reduce
your risk of the type 2 form of diabetes.

9. The Antioxidants found in Olive Oil Have Anti-Cancer Properties
Cancer is one of the most prevalent causes of death across the world.

People in Mediterranean countries are less at risk of some cancers, and many scientists believe that olive oil may be the cause ( 39Trusted Source).

The antioxidants in olive oil are able to reduce oxidative damage due to free radicals. This is believed to be a leading cause of cancer ( 40Trusted Source, 41Trusted Source).

Many studies in test tubes show that olive oil's antioxidants are able to combat cancerous cells ( 42Trusted Source, 43Trusted Source).


Further research is required to determine if olive oil in fact reduces your risk of cancer.

Summary
Initial evidence suggests that olive oil is a good source of
could reduce the risk of cancer could reduce cancer risk, however, more research is needed.

10. Olive Oil Can Help Treat Rheumatoid Arthritis
Rheumatoid arthritis is an autoimmune disorder characterized by deformed and painful joints.

While the precise cause isn't well identified, it's a result of your immune system attacking normal cells by mistake.


Olive oil supplements are believed to enhance inflammatory markers and lower the oxidative stress of people suffering from rheumatoid arthritis ( 44Trusted Source, 45Trusted Source).

Olive oil can be especially beneficial when combined with fishing oil, a source of omega-3 fatty acids.

The results of one research study showed that the olive oil and fish oil significantly increased handgrip strength, joint pain , and stiffness in the morning for people suffering from Rheumatoid arthritis. ( 46Trusted Source).
