Different Oils For Frying and Endothelial Function

May 12, 2009 updated by: Hospital Universitario Reina Sofia de Cordoba

Comparative Effect Of Different Oils For Frying On The Endothelial Function, The Oxidative Stress And The Postprandial Inflammatory Response

The purpose of this study is to compare the effects of the consumption of different oils (olive oil, sunflower oil, sunflower plus dimethyl-polysiloxane, sunflower plus phenols) previously submitted to heating in postprandial endothelial function, inflammation and oxidative stress in healthy young men.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

To determine whether the consumption by healthy persons of an oil exposed to high temperatures, designed to have a composition of healthy fats (predominantly monounsaturated fats and with less than 10% palmitic acid) and to contain an abundance of antioxidants typically found in olive oil (phenolic compounds), will improve the vasodilatory response that depends on the endothelium, and buffer the inflammatory and postprandial oxidative response that is produced by the oils that are being used ever more frequently for frying purposes (sunflower oil and oil to which butylated hydroxytoluene (BHT) has been added), using virgin olive oil exposed to the same heating regime as a reference oil.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Investigators will select obese people (BMI ranged 25 to 40).

Exclusion Criteria:

  • Evidence of malignancy or severally ill (life expectancy lesser than 5 years).

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: 1
All the volunteer subjects will be administered four breakfast meals that have been prepared with four different types of oil, each of which will have been subjected to a standardised frying. The meals will be administered according to a cross-randomized Latin squares design
Dietary supplement: Olive Oil, SF, SF+DMP, SF+phenols

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Endothelium-dependent postprandial vasodilatation measured by laser-doppler after the consumption of 4 different oils: -Virgin Olive Oil -Sunflower Oil -Sunflower High Oleic plus phenols -Sunflower High Oleic plus dimethylpolysiloxane
Time Frame: 0, 2, 4 hours after the meals
0, 2, 4 hours after the meals

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Assessment of pro-oxidative state, as evaluated via the determination of F2 isoprostane, nitrates and nitrites, total plasma antioxidative capacity, lipoperoxides and oxidised proteins.
Time Frame: 0 and 4 hours after the meal
0 and 4 hours after the meal
Assessment of proinflammatory state in both soluble plasma markers (IL-6, TNF-alpha, MCP-1, VCAM-1, ICAM-1) and the postprandial activation (RNAm) of IL-6, TNF-alpha, Rel-A, I-kappaB-alpha, MIF, MMP-9 y MCP-1 genes.
Time Frame: 0 and 4 hours after the meal
0 and 4 hours after the meal
Assessment of interrelationship of postprandial lipaemic response and the response of the inflammatory markers and of the oxidative metabolism with each of the oils employed in the study.
Time Frame: 0, 4 hours after the meal
0, 4 hours after the meal
