Dear Melissa, I wish I had a better answer to your question. It is clear that sugar (i.e sucrose) increases heart rate. However, not much work has been done on the differences in these effects between men and women and boys and girls. Caffiene, on the other hand is known to decrease heart rate in both men in women. The studies that I looked at showed no difference in the repsonses of men or women to caffiene in terms of heart rate or blood pressure (which rises). Maybe you and your classmates can do some groundbreaking experiments on the differential effects of sugar. Lastly, I would suggest that you ask your family doctor as well. Good luck, Terry
