A randomized, cross-over and double-blind pilot study with 3 study arms is being performed to evaluate the satiating properties of different canned tuna preserved in olive oil enriched with soluble fiber or polyphenols on overweight subjects.~The investigators included 12 participants (6 men and 6 women) between 18 and 55 years (BMI ≥25 and <30 kg / m2). All volunteers will be randomized into 3 study groups, and participants will receive the 3 different study products in order during the 3 experimental phases.
The purpose of this study is to evaluate the satiating effects of different canned tuna preserved in olive oil enriched with soluble fiber or polyphenols on overweight subjects (BMI ≥25 and <30 kg / m2).~Some studies have shown the contribution of high-fiber foods in the reduction of the cardiovascular risk.
