One of the foods to which attention is drawn in the Qur’an is the olive. Research in recent years has revealed that the olive is not just a delicious food but also represents an important source of good health. In addition to the olive itself, olive oil is also an important source of nutrition. Attention is drawn to the oil of the olive tree in these terms in the Qur’an:
Allah is the Light of the heavens and the earth. The metaphor of His Light is that of a niche in which is a lamp, the lamp inside a glass, the glass like a brilliant star, lit from a blessed tree, an olive, neither of the east nor of the west, its oil all but giving off light even if no fire touches it. Light upon Light. Allah guides to His Light whoever He wills and Allah makes metaphors for mankind and Allah has knowledge of all things. (Qur’an, 24:35)
The expression “mubarakatin zaytoonatin” in the above verse describes the olive as being “plentiful, sacred, auspicious, providing countless blessings.” Olive oil, referred to in the term “zaytuha,” is known as one of the most highly recommended types of oil by all experts, especially for coronary and arterial health. Its health benefits may be summarised as follows:
Benefits for Coronary and Arterial Health:
Most of the fatty acids in olives and olive oil are mono-unsaturated. Mono-unsaturated fatty acids do not contain cholesterol. Therefore, olive oil does not raise cholesterol levels but instead keeps them under control. Olive oil also contains omega-6 linoleic acid (EFA: essential fatty acid), which is essential for the human body. Due to this feature, health-related bodies (such as The World Health Organization) recommend that at least 30% of the fatty acid consumed in societies in which hardened artery and diabetes levels are high should consist of omega-6. This increases the importance of the olive still further.127
And by it He makes crops grow for you and olives and dates and grapes and fruit of every kind. There is certainly a Sign in that
for people who reflect.
Studies in this area have revealed much lower LDL (bad cholesterol) and higher antioxidant levels in people who consume 25 millilitres (about two dessertspoonfuls) of natural olive oil a day for one week.128 Antioxidants are important as they neutralise the harmful substances in the body known as free radicals and prevent cell damage. It has also been established in a great many studies that the consumption of olive oil reduces cholesterol levels and prevents heart disease.129
Olive oil is also recommended for patients with heart and artery disease since it reduces the level of harmful cholesterol (LDL) in the bloodstream and raises that of useful cholesterol (HDL).130 In countries with high occurrences of heart and artery diseases, saturated fats with high cholesterol content are generally consumed.
In addition, olive oil does not disrupt the proportion of omega-6 to that of omega-3. It is very important that omega-3 and omega-6 be present in the body at specific levels because any imbalance in these proportions can lead to progression in many diseases, especially those of the heart and immune system and cancer.131 For all these reasons, many people enjoy good health thanks to olive oil. The American Heart Association suggests that in order to reduce the risk of heart disease high mono-unsaturated fats can be an alternative to a 30% reduced fat diet.132
One study, published by The Archives of Internal Medicine, showed that women who consume high levels of mono-unsaturated fat have a lower risk of developing breast cancer.133 Another study by scientists at the University at Buffalo, The State University of New York demonstrated that b-sitosterol, a fat found in vegetable oils such as olive oil, helps prevent the formation of prostate cancer cells. The researchers concluded that b-sitosterol strengthens the internal communication system of the cell that issues the command for the cells to divide and that cancer can thus be prevented before cell division reaches an uncontrollable level.
A recent study by doctors at the University of Oxford has shown that olive oil has a protective effect against intestinal cancer. The doctors discovered that olive oil enters into a reaction with stomach acid in order to prevent intestinal cancer from beginning. At the same time, the University of Oxford researchers also established that olive oil reduces the level of bile and raises that of DAO (the enzyme diamine oxidase), thus protecting against abnormal cell growth and cancer.134
Prevention of Arthritis
According to researchers’ reports, people who consume large quantities of olive oil and cooked vegetables can have a reduced risk of rheumatic arthritis, a chronic inflammatory disease of the joints.
Olive Oil Assists Bone Development
The vitamins E, A, D and K contained in olive oil are particularly important from the point of view of assisting bone development in adults and children, and in strengthening the bones by fixing calcium. It is also recommended for the elderly as it is easily digested and through its minerals, it assists with the use of vitamins in the body. It also prevents calcium loss by stimulating bone mineralisation.135 Bones are the organism’s mineral structure storehouses and an absence of mineral accumulation in the bones can lead to serious complications such as bone softening. Olive oil has a most beneficial effect on the skeleton in this regard.
Prevention of Aging
Since the vitamins contained in olive oil have a cell renewing effect they are also employed in the treatment of the elderly, as well as nourishing and protecting the skin. As foodstuffs are transformed into energy in our bodies, certain substances known as oxidants are formed. With the high levels of anti-oxidants it contains, olive oil prevents damage by harmful substances, renews our cells and delays aging in the tissues and organs. Olive oil is also rich in vitamin E, which suppresses the free radicals that destroy the cells in our bodies and cause aging.
Contribution to Child Development
Due to the linoleic acid (omega-6 fatty acid) contained in olives and olive oil, these are a most healthy food for newborn babies and growing children. A deficiency in linoleic acid leads to the emergence of a retardation of development in babyhood and various skin disorders.
Olive oil contains anti-oxidant elements that prevent the destructive effects of harmful substances in our bodies, and fatty acids of great importance to human health. These support the hormones and assist in cell membrane formation.
Olive oil possesses a balanced polyunsaturated compound at a similar level to that in human milk. Olive oil is a sufficient source of these fatty acids, which cannot be obtained from the human body but which are of the most essential importance to it. These factors make olive oil very important for new-born babies.
Since it contributes to the natural development of the baby’s brain and nervous system before and after birth, olive oil is the only oil recommended for mothers by experts. As well as containing similar levels of linoleic acid to those of mother’s milk, when olive oil is added to fatless cow’s milk, it becomes as natural a food source as mother’s milk itself.
Blood Pressure Reduction
One study published in the 27 March 2000 edition of Archives of Internal Medicine once more stressed the beneficial effect of olive oil on high blood pressure. Medicines to reduce high blood pressure are also made from olive leaves.
Benefits for the Internal Organs
Whether consumed hot or cold, olive oil protects the stomach against diseases such as gastritis and ulcers by reducing gastric acid levels.136 In addition to this, by activating the bile, it makes it perfect. It regulates the discharge of the gall bladder and reduces the risk of bile stone formation.137 Moreover, thanks to the chloride it contains, it also assists the functioning of the liver and thus helps the body eliminate waste products. In addition, it also has a beneficial effect on the brain arteries.138
On account of all these properties, olive oil has attracted considerable expert attention in recent years.139 Some of the comments made by experts are as follows:
Jean Carper, a prominent authority in the field of health and nutrition, the CNN award-winning correspondent, columnist and author of The Food Pharmacy and Food-Your Miracle Medicine:
New Italian research finds olive oil contains antioxidants… that combat disease processes, including LDL cholesterol’s ability to clog arteries.
Pat Baird, a dietician and nutrition consultant:
I love the whole idea of olive oil’s versatility… the more we know about it, the more we learn about its great contribution to good health.
Dr. Dimitrios Trichopoulos, chairman of the Department of Epidemiology, Harvard University School of Public Health:
American women might actually experience as much as a fifty percent (50%) reduction in breast cancer risk if they consumed more olive oil in place of saturated fats.
Olive oil has a protective effect against some types of malignant tumors: prostate, breast, colon, squamous cell, and oesophageal.
D. Peck of the School of Medicine, University of Miami:
Olive oil has been shown to strengthen the immune system in mice…
Bruno Berra of the Institute of General Physiology and Biological Chemistry, University of Milan:
… [T]he minor polar components of extra virgin olive oil increase significantly the resistance of LDL to oxidation.
A.A. Rivellese, G. Riccardi and M. Mancini of the Institute of Internal Medicine and Metabolic Diseases at Federico II University, Naples:
Olive oil prevents insulin resistance and ensures better control of the glucose in the blood.
Patrizia Galletti of the Second University of Naples, Faculty of Medicine and Surgery:
Dietary intake of olive oil polyphenols may lower the risk of reactive oxygen metabolite-mediated diseases such as some gastrointestinal diseases and atherosclerosis. Olive oil hydroxytyrosol protects human erythrocytes against oxidative damage.
Frank Sacks of the Harvard School of Public Health:
An olive-oil-rich diet is more effective than a low-fat diet in controlling and treating obesity. Moreover, it leads to longer-lasting weight loss and it is easier to keep to…
As we have seen, a great many scientists today think that an olive oil-based diet constitutes the ideal nutritional model. It is stated that on account of these properties, olives and olive oil should be the fundamental constituents of every meal in one’s daily nutrition programme. The benefits of the olive plant, emphasised by Allah in many verses of the Qur’an, have been discovered in parallel to the advances made by medical science.
It is He Who sends down water from the sky. From it you drink and from it come the shrubs among which you graze your herds. And by it He makes crops grow for you and olives and dates and grapes and fruit of every kind. There is certainly a Sign in that for people who reflect. (Qur’an, 16:10-11)
