Two clinical trials with 132 volunteers have verified that regular consumption Olive pomace oil lowers cholesterol and improves insulin sensitivity, as well as having a positive effect against obesity.
The results are published in the European Journal of Nutrition, Nutrients and Foods, and a team from the Institute of Food and Nutrition Science and Technology (ICTAN) of the Higher Scientific Research Council (CSIC) is behind the study.
research shows how Regular consumption of olive pomace oil can have a positive effect on cardiovascular health and in related maladies, such as diabetes and obesity.
Results are obtained from two clinical trials of nutritional interventions in 132 healthy volunteers and at-risk subjects (hypercholesterolemic), comparing the effects of olive pomace oil with sunflower oil and high oleic sunflower oil.
Oil is obtained from olive pomace alperujois a product made of olive residue that remains after the extraction of virgin olive oilexplains CSIC in a note.
“When we started this project, there had only been ‘in vitro’ or preclinical studies in experimental animals with certain components of olive pomace oil,” says Laura Bravo Clemente, CSIC researcher at ICTAN. However, he adds, the effect of regular consumption of this oil in people was not known.
For this reason, the team set out to evaluate the effect of their daily consumption on cardiovascular health and two related pathologies, such as diabetes and obesity, in both healthy consumers and those at cardiovascular risk.
For this purpose, Two clinical studies have been conducted for more than four years Randomised, controlled, crossover and blinded intervention trial in 132 volunteers.
Researchers divided participants into two groups to consume either olive pomace oil or a control oil for four weeks. After this time and the washout phase, the participants were crossed over to consume the other oil during the same time period.
The study was blinded, so the volunteers were unaware of the oil we provided them at each step and that He consumed at the rate of 45 grams per day, Their consumption of other fatty dietary sources was restricted”, explains Raquel Mateos Bridges.
What are the benefits of olive oil?
The results obtained have shown Positive impact Regular consumption of olive pomace oil against cardiovascular disease in both healthy subjects group and risk group (hypercholesterolemic volunteers).
It was observed that a Improve blood lipid profile Thanks to a decrease in total cholesterol and low-density lipoprotein (LDL or bad cholesterol) levels in the subjects.
On the other hand, consumption of olive pomace oil also Waist circumference has decreased significantly analyzed in two groups, an essential marker in the evaluation of patients with obesity, which is associated with increased cardiometabolic risk, and better biomarkers related to insulin resistance and sensitivity,
In the case of the group of healthy consumers, the benefit of regular consumption of olive pomace oil was also transferred to the marker. oxidative stressConsidered as a pathophysiological condition associated with increased cardiovascular risk.
With respect to type 2 diabetes mellitus, the results have shown a drop in insulin levels and in the Insulin Resistance Index (HOMA-IR),
The study is part of research work promoted by Olive Pomace Oil Interprofessional. Since its creation in 2015, the organization has promoted eight probes In association with CSIC.
