Cocoa/Carob Polyphenols and Postprandial Changes in Type 2 Diabetes

The subjects will receive, after overnight fasting, a high-fat high-sugar breakfast. In treatment A, they will not receive any additional product; in treatment B, they will receive at the same time a mixture of coca and carob; in treatment C, they will receive the mixture of coca and carob 10 h before breakfast. A total of 6 blood samples will be collected during each visit: 0-30-60-120-180-240-270 min. Urine samples will be collected during the permanence of the subjects in the Unit of Human Nutrition. Feces will be collected the first time they are generated after treatments A and C. Both interventions will be separated by two weeks. Subjects will be instructed not to modify their dietary habits during the development of the study, but during the 72 h before each visit they will have to restrict the intake of polyphenol-rich foods (a detailed list will be provided).
