What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| endothelial function | Changes in the dilatation of the Humeral artery. | The measurements of endothelial function are taken with an ultrasound on two different occasions. The measurements will be made at baseline and after eight weeks of product consumption. | 
| blood samples | Change in total cholesterol levels. | Total cholesterol measurements are taken with the ILAB 600 analyzer on two different occasions. The measurements are made at the beginning and after eight weeks of consumption of the product. | 
| Tests | Change in physical activity with the World Physical Activity Questionnaire (GPAQ) | Quality of life measurements are taken on two different occasions. Measurements are made at the beginning and after eight weeks of product consumption. | 
| nutritional record | Volunteers record dietary intake for three days in a notebook. They will describe the amount of food they consume in grams in order to assess changes in intake during the clinical trial. | The dietary intake will be controlled by a diary in which meals will be recorded for three days and on two different occasions. The measurements are made at the beginning and after eight weeks of consumption of the product. | 
| body composition | Changes in body composition were measured with a TANITA | Body measurements are taken with a Tanita on two different occasions. The measurements are made at the beginning and after eight weeks of consumption of the product. | 
| cardiovascular risk | Changes in systolic blood pressure (mmHg), dystolic blood pressure (mmHg) and heart rate (beats per minute). | Cardiovascular risk measurements are taken by laboratory analysis on two different occasions. The measurements are made at the beginning and after eight weeks of consumption of the product. | 
| Tests | Change in the quality of life (SF-12). | Quality of life measurements are taken on two different occasions. Measurements are made at the beginning and after eight weeks of product consumption. |
