Title: Postprandial Effect of Breakfast Glycemic Index on Vascular Function, Insulinemia and Cognitive Performance, a Crossover Clinical Trial (BGI Study)
Brief Summary: This is a crossover clinical trial aimed at adults (aged 20-40 years, with no cardiovascular disease), selected by consecutive sampling at urban primary care health clinics in Salamanca (Spain). Each subject will complete three interventions, with a washout period of one week: control breakfast (water), low glycemic index breakfast (apple, yogurt, walnuts and black chocolate) and high glycemic index breakfast (grape juice, bread and strawberry jam). The postprandial effect will be assessed at 60 and 120 minutes from each breakfast, measuring blood glucose and insulin and cognitive performance. Measurements will be performed of central blood pressure, augmentation index, pulse wave velocity, cardiac output and total peripheral vascular resistance at minutes (-10, 0, +15, +30, +45, +60, +75, +90, +105 and +120).
