NCT06353009

Brief Summary

The objective of this study is to evaluate the effect of an ultra-processed meal on myocardial endothelial function using positron emission tomography (PET). The proposed study is an open-label, randomized crossover clinical trial. Participants will be divided into 2 groups: half of the participants will consume a Mediterranean meal during the first experimental visit and an ultra-processed meal during the second, and vice versa for the other half. The order in which the meals will be consumed will be determined randomly. This project will contribute to clarify the role of diet in the development and progression of coronary artery disease. The results obtained from this study may potentially demonstrate the harmful effect of ultra-processed foods, even in the short term, on coronary arteries.

Conditions

Outcome Measures

Primary Outcomes (1)

  • Myocardial blood flow values (ml/min/g) at maximum dose of adenosine.

    The difference in maximum dose adenosine myocardial blood flow measured after consumption of ultra-processed (NOVA 4) and Mediterranean meals (NOVA 1-3) in healthy subjects.

    4 hours after meal consumption

Secondary Outcomes (2)

  • Myocardial blood flow values (ml/min/g) at rest and myocardial reserve.

    4 hours after meal consumption

  • Myocardial blood flow values (ml/min/g) at intermediate dose of adenosine.

    4 hours after meal consumption

Interventions

NOVA (a name, not an acronym) is a food classification system divided into four groups, based on the level of processing. Group 4 - Ultra-processed foods. They are the ones that use many ingredients including food additives that improve palatability, processed raw materials (hydrogenated fats, modified starches, etc.) and ingredients that are rarely used in home cooking such as soy protein or mechanically separated meat. These foods are mainly of industrial origin and are characterized by a good pleasantness and the fact that they can be stored for a long time.

NOVA (a name, not an acronym) is a food classification system divided into four groups, based on the level of processing. Group 1 - Unprocessed or minimally processed foods (fruit, vegetables, eggs, meat, milk, etc.) Group 2 - Foods processed in the kitchen with the aim of extending their shelf life. In practice, these are ingredients to be used in the kitchen such as fats, aromatic herbs, etc. to be kept in jars or in the refrigerator to be able to use them later. Group 3 - Processed foods. These are the foods obtained by combining foods of groups 1 and 2 to obtain the many food products for domestic use (bread, jams, etc.) made up of a few ingredients
