Modern science is steadily confirming the healing properties attributed to the olive in ancient times. Decades of research have demonstrated the extraordinary effects of the olive on human health.

Cardiovascular Health
Oleic acid in olives and olive oil lowers LDL (bad) cholesterol while raising HDL (good) cholesterol. Comprehensive studies on the Mediterranean diet have shown that regular olive consumption reduces the risk of heart disease by 30–40%.
- Prevents arterial hardening (atherosclerosis)
- Helps regulate blood pressure
- Reduces platelet aggregation, lowering clot risk
- Shows a protective effect against cardiac arrhythmias
💚 Scientific Evidence
The PREDIMED study, published in the New England Journal of Medicine in 2013, proved that a Mediterranean diet rich in olive oil reduces the risk of heart attack and stroke by 30%. It is one of the most important studies in the history of nutritional science.
Antioxidant and Anti-inflammatory Properties
Olives are exceptionally rich in powerful antioxidants. The compound oleocanthal displays anti-inflammatory effects similar to ibuprofen, providing natural protection against diseases linked to chronic inflammation.
Cancer Protection
Epidemiological research shows certain cancers are less prevalent in Mediterranean countries. The polyphenols and oleic acid in olives show cell-protective effects particularly against breast, colon and prostate cancer.
Brain and Nervous System
Oleocanthal in olive oil has shown the capacity to clear Alzheimer-associated beta-amyloid plaques from brain tissue. Additionally, omega-9 fatty acids support the myelination of nerve cells, helping to preserve brain function.
Bone Health
Olive oil polyphenols have been shown to increase bone density and slow the onset of osteoporosis — results particularly notable for post-menopausal women.
Skin and Hair
Rich in vitamin E, olive oil protects skin cells from free radical damage. Today science confirms that olive oil delivers superior moisturising results compared to commercial creams.
