Can olive oil be more than just a food ingredient on the table? And does it really have the ability to support health and help prevent certain diseases? This question was raised by a fatty liver patient during a medical visit, opening a story that reveals how oleic acid extracted from olive oil contributed to one of the most famous scientific and human stories in the history of modern medicine.
Mahmoud, a patient suffering from fatty liver disease, walked into Dr. Ahmed's clinic and said anxiously:
Doctor, everyone is talking about olive oil, but does it really deserve all this fame?
Dr. Ahmed: Certainly. We advise fatty liver patients to replace saturated fats with extra virgin olive oil because it contains oleic acid and many antioxidant compounds that support liver and heart health.
Mahmoud: But are there real examples that show the importance of this oil?
Dr. Ahmed: Let me tell you a moving scientific story that showed how one of olive oil's components could become part of an unprecedented medical achievement.
In 1984, the American boy Lorenzo Odone was diagnosed with a rare genetic disease known as cerebral adrenoleukodystrophy (ALD). The disease causes very long-chain fatty acids to accumulate in the body, destroying the protective sheath of the nerves and leading to rapid and severe neurological decline.
Doctors told his parents at the time that medicine had no effective treatment and that the child's future looked bleak. But his parents, Augusto and Michaela Odone, refused to give up and set out on an extraordinary scientific journey to understand the disease and its biochemical mechanisms.
After long months of study and correspondence with scientists around the world, they arrived at an idea based on blocking the body's production of the harmful fatty acids by supplying other fatty acids that compete with them for the same metabolic pathways.
The starting point was oleic acid, the monounsaturated fatty acid that forms the main component of olive oil. It succeeded in noticeably lowering the levels of the harmful fats, but it was not enough on its own.
After further research, a therapeutic formulation was developed that later became known as "Lorenzo's Oil", turning into one of the most famous stories embodying the power of persistence and scientific research.
Lorenzo's Oil is a precise blend of two fatty acids in the form of triglycerides:
The formulation is prepared at a precise ratio of four parts glyceryl trioleate to one part glyceryl trierucate.
Lorenzo's Oil does not repair nerve damage that has already occurred. Instead, it relies on what is scientifically known as "competitive inhibition".
In other words, the fatty acids in the formulation occupy some of the enzymes responsible for synthesising very long-chain fatty acids, which reduces their production and slows their accumulation in the body.
Studies have shown that this strategy is most effective when used preventively, before neurological symptoms appear and before any visible damage occurs in the brain.
Dr. Ahmed explained to his patient that the renowned physician and researcher Hugo Moser and his research team reached important findings showing that the formulation, most of which is oleic acid extracted from olive oil, can delay or prevent the onset of neurological symptoms in boys carrying the disease gene when given at a very early stage, before symptoms appear and before changes are detected on magnetic resonance imaging (MRI).
This confirms an important truth in nutrition and therapy: some food components can play a role beyond conventional nutrition and become part of science-backed preventive strategies.
Mahmoud: So does olive oil treat fatty liver the way it helped in this story?
Dr. Ahmed: No. Every disease has its own mechanisms, and different medical conditions should not be confused. But the story highlights the scientific value of oleic acid, the main component of olive oil. As for fatty liver, including extra virgin olive oil in a balanced diet, alongside weight loss and physical activity, is one of the recommended dietary choices to support liver health and improve the quality of fats in the diet.
Lorenzo's story is not just a moving medical tale; it is proof that scientific research can reveal surprising roles for natural food ingredients we keep in our kitchens every day. Extra virgin olive oil remains one of the most prominent of these ingredients, not only for its high nutritional value but also because it contains oleic acid, which was an essential part of one of the best-known preventive therapeutic innovations in the history of rare genetic diseases.
In the end, olive oil may not be a magic cure for every disease, but it remains one of the best dietary investments in human health when it is part of a healthy, balanced lifestyle.
