The benefits of the olive tree on our body

Sep 27, 2023

The majestic olive tree, or Olea europaea , is a tree that is held in high esteem in many cultures around the world, from the Mediterranean to North Africa. Despite its cultural importance, we tend to overlook its importance for our physical well-being. Could it be that we are looking for complicated health solutions when the answer lies in the simplicity of this tree?

More than a symbol of peace and longevity, the olive tree has undeniable nutritional and pharmacological benefits . Its fruits, leaves and oil have beneficial impacts on our body that are not limited to the antioxidant content. The Mediterranean diet is often cited as a model of health and well-being - and the olive tree plays a determining role.

“In each olive seed lies a microcosm of benefits for the body that humanity has learned to use to its advantage for millennia”

So, what are these benefits of the olive tree on our body? Let's review the different parts of the olive tree and the benefits they can bring us.

Olive polyphenols and their role in the fight against aging

The olive tree, this ancient tree from the Mediterranean basin, is recognized for its countless health benefits, particularly thanks to its polyphenols . But what exactly is it and how do these compounds play a role in the fight against aging? This is what we will detail. 

Polyphenols, these powerful antioxidants

Major constituents of olive oil , polyphenols are chemical compounds with powerful antioxidant properties . These molecules protect the body's cells against free radicals , the unstable chemical species responsible for premature aging. Where do they come from, though? Could it be that our own bodily processes produce these dangerous radicals?

“Yes, absolutely. Free radicals are the normal result of cell metabolism. But exposure to pollution, stress, poor diet or smoking can also induce them,” explain the researchers in the journal Reviews of Physiology.

Hydroxytyrosol and tyrosol, two key polyphenols

Not only does olive oil contain polyphenols, but they are extremely effective. Hydroxytyrosol and tyroso l, two of the dominant phenolic compounds in olive oil, are particularly effective in preventing cellular aging .

Studies have shown that hydroxytyrosol can decrease oxidative stress , a key factor in premature aging, and improve cell longevity . Likewise, tyrosol has powerful antioxidant activity , in addition to promoting cellular detoxification .

Interestingly, olive leaves also contain such polyphenols , and their infusion is often used in herbal medicine for its beneficial health effects .

Other benefits of olive polyphenols

In addition to their direct antioxidant effect, olive polyphenols also promote healthy aging through other mechanisms. They can improve cardiovascular health, protect the liver, support immunity and regulate blood sugar levels , all important aspects of maintaining good health as we age.

It is therefore obvious that regularly consuming olive products can help prevent premature aging. Consequently, the olive tree, considered since Antiquity as a symbol of longevity, confirms its role through its richness in polyphenols. Why not enrich our daily diet with this precious ally of well-being?

Cardiovascular protection thanks to the olive tree

Without a doubt, the olive tree plays a significant role in cardiovascular protection . Can this statement surprise some of us? Maybe. However, it is necessary to understand the underlying mechanisms to fully understand the scope of this declaration.

The effectiveness of the olive tree in the prevention of cardiovascular diseases is well documented in the scientific literature. Let's see how he manages to do this.

Regulation of cholesterol levels

One of the major risk factors for cardiovascular disease is undoubtedly high cholesterol . How then does the olive tree intervene in this situation?

Various studies have shown that the olive tree, thanks to its active components such as hydroxytyrosol , contributes to the regulation of cholesterol levels . It helps maintain a balance between HDL cholesterol (good cholesterol) and LDL cholesterol (bad cholesterol). That’s a remarkable feat, isn’t it?

Anti-hypertensive effect

In addition, the olive tree has a proven beneficial effect on blood pressure . Is this really possible? Of course. The olive tree, in fact, is known to help regulate blood pressure , thus contributing to better cardiovascular health.

It should also be noted that the consumption of olive oil , rich in monounsaturated fatty acids , is associated with a decrease in systolic and diastolic blood pressure , thus adding another string to the bow of the olive tree for support cardiovascular health.

Reduction of inflammation and platelet aggregation

Last, but not least, the olive tree has anti-inflammatory and anti-aggregating properties that are essential for cardiovascular health. How exactly does this work?

The active components of the olive tree, again hydroxytyrosol and other polyphenols , help reduce vascular inflammation and prevent platelet aggregation . These are two key factors in the development of cardiovascular pathologies, such as atherosclerosis .

In short, the olive tree promotes optimal cardiovascular health through various mechanisms . By reducing high cholesterol , regulating blood pressure and fighting inflammation and platelet aggregation, the olive tree is an essential ally for the health of the heart and blood vessels.

The antioxidant benefits of the olive tree

The olive tree, also known as Olea europaea, is a venerable tree that has stood the test of time thanks to its unparalleled resistance , particularly to difficult and severe environmental conditions. Can its robustness be transposed to our body? The answer is a resounding yes. One of the major virtues of the olive tree lies in its undeniable antioxidant potential, which is manifested in particular by the presence of numerous active substances with antioxidant properties in its leaves and its fruit.

Antioxidant processes of the olive tree

Antioxidants are key elements in the fight against aging . How exactly do they work? In the human body, the process of metabolism results in the production of harmful molecules called free radicals. These molecules can cause cellular damage and contribute to the onset of various aging-related diseases, such as cancer, cardiovascular disease, and age-related macular degeneration . Antioxidants intervene by neutralizing these free radicals , thus limiting the damage they can cause.

Products derived from the olive tree, such as olive oil and olive leaves, are a rich source of antioxidants , particularly polyphenols. Olives, their oil, and the leaves of the tree contain phenomenal antioxidants.

Immune system support

In addition to their action on aging and oxidative stress, olive antioxidants have recognized beneficial effects on the immune system . They help to support and stimulate the body's natural defenses , thus strengthening our ability to fight infections and diseases.

Thus, the olive tree represents a valuable source of antioxidants which contribute to the overall protection of our body. But the tree is not limited to this single asset: this plant treasure contains many other riches for our health, and the journey to discover these benefits has only just begun...
