Properties and Benefits of Olives

Properties and Benefits of Olives: One of the most widely consumed and expensive foods in the world, olives boast great antioxidant and anti-inflammatory properties. Olives are considered culinary vegetables, but botanically, they are a fruit.

Olives are the fruit of the olive tree (Olea europaea). One of their key-features is their oily flesh, rich in healthy monounsaturated fatty acids which exert a powerful antioxidant and anti-inflammatory action on our blood vessels. Olives, just like their main byproduct, olive oil, support cardiovascular health and protect against oxidative stress and chronic disease.

Olives benefits

Olive trees are of medium height and bulky, with a somewhat twisted, at parts hollow trunk. Interesting fact: did you know that olive trees may live up to a few hundred years and produce fruit throughout their lifespan? Olives ripe similar to mirabelles or plums, turning from green to red-purple and finally black. The green olives present in supermarkets or even local markets are unripe.

Green olives with patches or smudges of red-purple are in the process of ripening, while dark purple and black olives indicate the fruit is mature. Freshly picked olives are bitter which is why they undergo special treatments before reaching supermarket shelves and our plates, in order to make them more palatable. Usually, treatments applied to the fruit involve the use of lye or salt or both.


But what are the health benefits of olives? According to more recent research, the health benefits of olive consumption derive mainly from the antioxidant and anti-inflammatory action of the fruit. Hydroxytyrosol is a powerful antioxidant phenol found in fresh olive pulp, olive oil and olive leaves.

Hydroxytyrosol has been shown to protect cells against oxidative stress caused by free radicals. By limiting cell damage and promoting cell repair, antioxidants are believed to significantly reduce the risks of chronic disease such as heart disease and cancer. The hydroxytyrosol in olives appears to be highly protective of lung health in smokers. Fresh olives are by far the best source of hydroxytyrosol because the antioxidant content is easily damaged by canning methods and other processes.

Traditional medical practices used olive pulp and leaves to treat inflammatory problems. According to researchers, at cell level, extracts from olives act similar to antihistamines by blocking special receptors triggering inflammation.

The olive fruit as well as olive oil are representative of the Mediterranean diet, an eating regimen known to lower both heart disease and osteoporosis risks. Researchers focused on revealing the health benefits of the Mediterranean diet have found that eating olives is beneficial because it increases calcium absorption in bones, thus reducing osteoporosis risks.

Olive oil as well as fresh olives are a rich source of monounsaturated fatty acids (healthy fats). It is estimated that olive oil is 3/4 or 75% monounsaturated fat. Fatty acids ensure the health of cell membranes, through which cells communicate with each other. This means that electric nervous impulses from brain cells to other cells in our body are transmitted better when we have a low, but healthy fat intake, resulting in cognitive health.

Moreover, eating monounsaturated rich foods such as olives appears to lower high blood pressure and is thus beneficial for overall cardiovascular health, provided the healthy fats in the fruit replace other unhealthy fat sources in one’s diet and the total fat intake is considerably low.

A serving of tuna, salmon or mackerel and 2-3 tablespoons of olive oil each day can do wonders for our health. If you do not like fish, you can chew on some walnuts, almonds or sunflower seeds or eat a handful of olives.

Last but not least, olives are an incredible source of antioxidants as well as anti-inflammatory compounds with great benefits on the cardiovascular, musculoskeletal, nervous, digestive and respiratory systems. Inflammation is the root of all disease, according to new scientific findings. Oxidative stress coming from free radicals damages cells and produces an inflammatory response in the body.

Moreover, inflammation has been linked to all sorts of chronic diseases such as diabetes, cancer, heart disease, even neurological diseases. Eating antioxidant-rich fruits, vegetables, nuts and seeds can improve overall health, keep inflammation levels low and offer protection against disease.

Depending on the variety and quality of the fruit, olives contains different amounts of antioxidant phenols, notably tyrosols, anthocyanins, quercitin and caffeic acid. In addition to this, they are a good source of vitamin E, a fat-soluble antioxidant vitamin that protects the skin against UV rays and sun damage. It is always best to choose quality brands with the least chemically-altered fruits. This will ensure both a enjoyable culinary experience and a generous intake of antioxidants, vitamins, minerals and healthy unsaturated fatty acids.
