Effect of High and Low Glycemic Index Foods on Post Meal Pulse and Blood Pressure

The aim of this study is to test high and low glycemic index foods in healthy adult volunteers and determine the effects on post meal pulse and blood pressure. Foods will be consumed before 8am after an overnight fast (10-12 hours) over a 10-15 minute period. Pulse and BP (where equipment is available) measurements will be taken 6 times at 5 min intervals before eating, and twice every 15 min thereafter for the following 2h. We will recruit between 30 to 40 students and 10 to 20 older adults to assess the effect of age, in cohorts of 10.
