Blood transport and genomic effects of olive oil components
Keywords:Olive oil, Monounsaturated fatty acids, Minor compounds, Intestinal secretion, Lipoproteins transport, Cellular response, Genes, Mediterranean diet
Epidemiological studies suggest that consuming diets rich in (extra virgin) olive oil is associated with a low incidence of chronic disease, including cardiovascular disease and cancer. Recent evidence has emerged which implicates raised concentrations of plasma triglycerides in the pathogenesis of coronary artery disease (CAD). It has been demonstrated that olive oil contributes to modulate metabolic processes related to secretion and transport of triglycerides. Intestinal triglyceride-rich lipoproteins from olive oil are very efficiently cleared during postprandial metabolism compared to other oils. Then, there is a massive interaction of nascent and remnant triglyceride-rich lipoproteins, as well as lipid metabolites and fat-soluble components, with hepatic and non-hepatic tissues. A diet-related response involves a multitude of gene products, including proteins implicated in lipid synthesis, oxidation and cell differentiation. Particularly, it has been reported a health beneficial effect of several components from (extra virgin) olive oil (fatty acids and minor compounds), which are functioning as regulators of gene transcription . This review reaffirm that a diet rich in extra virgin olive oil is of vital importance in the prevention of cardiovascular and other diseases.
