Human Intervention Study for Validating Foods With Improved Nutrient Profile

Cardiovascular Risk Factor Clinical Trial

Official title: Human Intervention Study for Validating the Influence of Regular Consumption of Foods With Improved Nutrient Profile on Cardiovascular Risk Factors

Status Completed

Clinical Trial Summary

The proposed intervention study is designed to evaluate the physiological impact of the regular consumption of the developed foods with improved nutrient profile (verum) in comparison to commercial available foods (control) by a controlled, randomized, double-blind crossover study with patients with measurable cardiovascular risk factors (LDL cholesterol ≥ 120 mg/dl (≥ 3 mmol/l) / Triacylglycerides ≥ 135 mg/dl (≥ 1,5 mmol/l)).

Clinical Trial Description

The proposed intervention study is designed to evaluate the physiological impact of regularly consumption of the food range with improved nutrient profile (verum) in comparison to commercially available foods (control/placebo).

The controlled, randomized, double-blind crossover study consists of 4-week investigation periods with a 11-week wash-out period in between. Patients (men, female, n = 54 + 6) with measurable cardiovascular risk (LDL cholesterol ≥ 120 mg/dl (≥ 3 mmol/l) / triacylglycerides ≥ 135 mg/dl (≥ 1,5 mmol/l)), are involved.

The product range includes sausages (raw, boiled and cooked varieties) and pasta fortified with dietary fibers, fish oil and plant protein, resulting in a reduction of fat and energy content. Eggs, bread, bread rolls, and mushrooms with higher vitamin D content complete the innovative product range. Additionally, participants receive ice cream where sugar is replaced by xylite.

In the control period, the participants receive commercially available foods (sausages (raw, boiled and cooked varieties), pasta, eggs, bread, bread rolls, and mushrooms, ice cream) with traditional nutrient profile.

The products will be offered in neutral packaging and are provided regularly by the study team. All personal (participants, physicians) are blinded.

At the beginning, participants are randomly allocated into the verum or the control/placebo group. After the wash-out phase the interventions will be crossed between the groups and the respective products are consumed also for four weeks. In the run-in phase of the study, all patients are invited to a medical examination to ensure the fulfillment of inclusion criteria.

At the beginning and at the end of each study period baseline parameters (BMI, waist-to-hip ratio, blood pressure, bioelectrical impedance measurement) are assessed, lifestyle questionnaires are filled, and venous blood samples are collected for the determination of cardiovascular risk markers.

Subjects document their normal nutritional habits over seven days in a food frequency protocol (FFP) before start and finish of each period. In addition, patients keep a diary for the documentation of nutrition, medication and adverse effects over both study periods. ;
