Hypertension Clinical Trial
Official title:
Antihypertensive and Cardioprotective Clinical Evaluation of a Functional Olive Oil Enriched in Bioactive Compounds From the Olive Tree
The general objective of this study is to evaluate the effect of a nutritional intervention with an extra virgin olive oil (EVOO) rich in bioactive compounds (polyphenols) and a functional oil of adequate organoleptic quality, prepared with the same EVOO rich in polyphenols and also enriched in triterpenic acid compounds from the olive itself, and demonstrate its antihypertensive and cardioprotective effect in children and adolescents (between 6-18 years) at risk of untreated hypertension.
A clinical study of nutritional intervention, randomized, adjusted by randomization blocks that consider age and sex, and parallel duration of 6 months, in 75 subjects (25 per randomization group) is proposed. The study will be carried out at the UGC of Pediatrics of the Reina Sofía University Hospital in Córdoba, as well as at the Institute of Nutrition and Food Technology of the University of Granada. The effects of an optimized oil rich in polyphenols and obtained by mixing varieties rich in said bioactive compounds (approx. 490 ppm), and a functional oil prepared with the same optimized oil and enriched with triterpenic acids obtained from the olive itself (approx. 490 ppm of polyphenols and 380 ppm of triterpenic acids). The study will be carried out in pediatric patients with high levels of untreated blood pressure, in which the effect of oils on blood pressure and their action on biomarkers of cardiovascular risk and on the intestinal microbiota will be evaluated, depending on the genotype specific to each subject. In addition, the presence of minor olive oil compounds present in the plasma will be analyzed (metabolomic analysis). In this way, at the end of the project, verified scientific information will be available on the enriched product and its effects on cardiovascular protection, and on possible mechanisms of action, as well as on its palatability and acceptance. The general objective of this study is to evaluate the effect of a nutritional intervention with an EVOO rich in bioactive compounds (polyphenols) and a functional oil of adequate organoleptic quality, prepared with the same EVOO rich in polyphenols and also enriched in triterpenic acid compounds from the olive itself, and demonstrate its antihypertensive and cardioprotective effect in children and adolescents (between 6-18 years) at risk of untreated hypertension. As specific objectives will be determined: - To evaluate the effect of olive oils on blood pressure levels - To evaluate the effect of olive oils on the levels of other components of the metabolic syndrome. - To evaluate the effect of olive oils on the antioxidant defense system - To evaluate the effect of olive oils on biomarkers of cardiovascular risk, including markers of inflammation and endothelial damage. - To evaluate the effect of olive oils on the intestinal microbiota. - To evaluate the effect of olive oils on metabolomic changes in plasma. - To analyze the specific genotype of each volunteer and its relationship with the clinical effects found. ;
