A fairly recent preliminary study has found that consuming extra virgin olive oil may improve the health status of Fibromyalgia patients.
The preliminary study found that extra virgin olive oil improves oxidative stress, functional capacity, and health-related psychological status in patients with fibromyalgia.
Fibromyalgia (FM) is a medical condition characterised by chronic widespread pain and a heightened pain response to pressure.
The pathophysiology of fibromyalgia is still not well understood, however the likes of mitochondrial dysfunction and oxidative stress are thought to play key roles in the condition.
I am a huge fan of using “functional foods” such as extra virgin olive oil for supporting health and reducing the risk of developing further degenerative diseases such as cardiovascular disease, of which oxidative stress and inflammation play key roles in the pathophysiology of these diseases also.
The scientific research indicates that olive oil may have many potential health benefits including reducing cardiovascular disease and diabetes risk, lowering blood pressure, improving endothelial function, reducing inflammatory biomarkers and much more.
Olive oil is thought to derive many of its health benefits from both its healthy fatty acid composition, of which it is a rich source of monounsaturated fatty acids (MUFA) and the polyphenol fraction.
Olive oil is an excellent source of various bioactive polyphenolic compounds such as oleocanthal, oleuropein, hydroxytyrosol, and tyrosol, all of which possess potent antioxidant and anti-inflammatory properties.
Extra Virgin Olive Oil Improves Oxidative Stress, Functional Capacity, and Health-Related Psychological Status in Patients With Fibromyalgia: A Preliminary Study:
The preliminary study published in 2017 aimed to investigate the effect of olive oil on oxidative stress and health-related parameters in FM.
Twenty-three women diagnosed with fibromyalgia consumed 50ml of Organic Olive Oil daily for three weeks.
Subjects were randomized into two groups: one ingested extra virgin olive oil (EVOO) and the other refined olive oil (ROO), which have different antioxidant content.
The patients’ oxidative (lipid, protein, and DNA oxidation) and antioxidative (antioxidant enzyme activities and compounds) profiles were examined before and after the treatment period. Functional capacity and physical and mental health status were assessed using the Fibromyalgia Impact Questionnaire (FIQ) and the Physical Component (PCS-12) and Mental Component Summaries (MCS-12) of the Short Form-12 Health Survey, respectively.
Significant differences were found in pre-post change between the EVOO and ROO groups for protein carbonyls, lipid peroxidation, and FIQ and MCS-12 scores. Differences between groups approached statistical significance for oxidative DNA damage and levels of the antioxidant compound zinc.
The preliminary study concluded:
EVOO may protect women with FM against oxidative stress in addition to improving functional capacity and health-related psychological status. Findings suggest that olive oil may be a valuable therapeutic support in FM.
