The phytonutrient in olive oil, oleocanthal, mimics the effect of ibuprofen in reducing inflammation(Beauchamp et al., 2005), which can decrease the risk of breast cancer and its recurrence(Marques, Gaspar, Costa, Paquete, & Correia, 2014),(Sun et al., 2012),(Akl et al., 2014).

Squalene(Kelly, 1999), (Rao, Newmark, & Reddy, 1998), (Desai, Wei, & Lamartiniere, 1996), and lignans(Menendez et al., 2009)(Williams et al., 2015),  are among the other olive oil components being studied for their possible effects on cancer(Servili et al., 2013).

Heart Disease

Olive oil lowers the levels of total blood cholesterol, LDL-cholesterol and triglycerides. At the same time it does not alter the levels of HDL-cholesterol (and may even raise them), which plays a protective role and prevents the formation of fatty patches, thus stimulating the elimination of the low-density lipoproteins.(Gordon, Kannel, Castelli, & Dawber, 1981), (Covas et al., 2006).(Fito et al., 2005), (Witztum, 1994), (Vissers, Zock, Wiseman, Meyboom, & Katan, 2001), (Nicolaiew et al., 1998), (Ramirez-Tortosa et al., 1999), (Orsavova, Misurcova, Ambrozova, Vicha, & Mlcek, 2015), (Rozati et al., 2015).

Oxidative Stress

Olive oil is rich in antioxidants, especially vitamin E(Goudarzi, Farsimadan, Chamjangali, & Bagherian, 2015), long thought to minimize cancer risk(Visioli, Bellomo, & Galli, 1998). Among plant oils, olive oil is onw of the highest in monounsaturated fat, which doesn’t oxidize in the body, and it’s low in polyunsaturated fat, the kind that does oxidize.(Orsavova et al., 2015)

Blood Pressure

Recent studies indicate that regular consumption of olive oil can help decrease both systolic and diastolic blood pressure(El & Karakaya, 2009), (Perrinjaquet-Moccetti et al., 2008), (Susalit et al., 2011), (Milajerdi, Maghsoudi, & Ghiasvand, 2016), (Rozati et al., 2015).


It has been demonstrated that a diet that is rich in olive oil, low in saturated fats, moderately rich in carbohydrates and soluble fiber from fruit, vegetables, pulses and grains is the most effective approach for diabetics. It helps lower “bad” low-density lipoproteins while improving blood sugar control and enhances insulin sensitivity(Kim, Keogh, & Clifton, 2016).




Although high in calories, olive oil has shown to help reduce levels of obesity. (Oliveira et al., 2015), (Razquin et al., 2009), (Soriguer et al., 2009), (Rozati et al., 2015).

Rheumatoid Arthritis

Although the reasons are still not fully clear, recent studies have proved that people with diets containing high levels of olive oil are less likely to develop rheumatiod arthritis (Silva et al., 2015), (Rosillo et al., 2016).


A high consumption of olive oil appears to improve bone mineralization and calcification. It helps calcium absorption and so plays an important role in aiding sufferers and in preventing the onset of Osteoporosis (Filip et al., 2015).
