The purpose of this research is to test the hypothesis that the consumption of meat products without additives, in comparison with their analogues with additives, could be beneficial in terms of modifying health markers. A 5-week clinical trial with two parallel arms will be performed with two parallel arms. Changes in different serum biomarkers of lipid metabolism, glucose, oxidative stress and inflammation will be analysed. Biomarkers related to digestive health, such as short chain fatty acid (SCFA) production and impact on the gut microbiota, will also be evaluated. Finally, factors such as body mass index (BMI), body fat percentage and markers of exposure to additives will be measured.
