Mediterranean Diet & Endothelial Function

Status Completed

Clinical Trial Summary

To assess the effect of Mediterranean diet and some of its specific components (olive oil, non fried fish and nuts) on endothelial function in overweight and obese patients

Clinical Trial Description

Abdominal obesity is well known to increase the risk of cardiovascular disease (CVD), since it is commonly associated with hypertension, dyslipidemia, impaired fasting glucose, type 2 diabetes, metabolic syndrome, insulin resistance, systemic inflammation and endothelium dysfunction.

Abnormal endothelial function, expressed as lower vasodilatation through flow-mediated vasodilatation (FMD) of brachial artery in response to an increase in blood flow, is considered an index of subclinical atherosclerosis, and an early hallmark of cardiovascular disease, with a strong prognostic value for future cardiovascular events. Changes in diet, level of physical activity and behavior are well known key elements influence endothelial function. Recent studies seem to show that Mediterranean diet has beneficial role on cardiovascular risk. It could protect against the development of coronary heart disease also through a possible effect on body weight and obesity.

At the best of our knowledge, the effect of Mediterranean diet on endothelial function in obese subjects has not been definitely established. Therefore, the aim of this study was to evaluate the impact of Mediterranean diet on anthropometric parameters (body weight, BMI and waist circumference), lipid profile [total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C)], triglycerides (TG), fasting glucose and endothelium function, evaluated by FMD, in a group of obese and overweight subjects. In particular, subjects were invited to follow a standard Mediterranean diet for a short (3 months) or a longer (18 months) period. The specific role of some components of Mediterranean diet (olive oil or non fried fish or nuts) was also investigated. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
