Effect of Tomato Soffritto Intake on Biomarkers of Cardiovascular Disease in an Overweight and Obesity — FRITOCARD  

Dietary Exposure Clinical Trial

Official title: Effect of the Intake of a Tomato Sofrito Preparation on Biomarkers of Cardiovascular Disease in an Overweight and/or Obese Population

Status Completed

Clinical Trial Summary

The study is a prospective, controlled, randomized two-arm longitudinal crossover trial, performed in a single-centre. Hence, the investigators designed a clinical study aimed to investigate the effects of a daily intake of soffritto in overweight or obese class-1 individuals without other cardiovascular risk. After a run-in period of two-week, participants were randomly separated in two different intervention sequences (two-arms) of six-weeks in which volunteers were administered with a soffritto (100 g/day) or a control group (without soffritto). After the first six-week period, participants had a wash-out phase of two-week followed by a second six-week period in which groups exchanged their interventions. During the duration of the study, the volunteers were asked to maintain their usual diet, excluding raw or cooked tomatoes, as well as tomato-based products (sauces, ketchup, juices, etc.) other than those administered during the study in the corresponding periods.

Clinical Trial Description

Sample size (N= 40) was calculated according results of previous studies on pigs (http://dx.doi.org/10.1016/j.trsl.2014.11.004). The study refers to healthy adult men (n=27) and women (n=13) with ages ranging from 25 to 60 years, non-smokers and with overweight (BMI: 25.0-29.9 kg/m2) or obesity class 1 (BMI: 30-34.9 kg/m2).

This study received approval from the Human Ethical Review Committee of Hospital Santa Creu I Sant Pau (Barcelona), with the reference number 12/181 and the date of approval being January 11, 2013. To confirm health status, all subjects underwent a complete physical examination conducted by the study physician.

The study lasted 16 weeks that were structured in:

• 2 weeks of run-in.

• 6 weeks of intervention period. During the intervention period, volunteers were administered with soffritto (100 g/day) or a control group (without soffritto).

• 2 weeks of wash-out.

• 6 weeks of intervention period. During the intervention period, volunteers exchanged their interventions

The volunteers visited the center at days 0, 14, 56, 70 and at the end of the intervention period (day 112).

Dietary habits were collected. Compliance was monitored by weekly telephone contact with participants and interviewing them at the end of each intervention period. Blood samples were collected early at the morning after twelve-hour fasting at baseline and at the end of each intervention phase. Blood samples were used for determining all variables of the study. Stool samples were obtained at baseline and after 42 days intervention for the study of platelet aggregation, lipid profile, biochemical measurements, vascular endothelial function and hemogram profile. ;
