Re: seeing that caffeine and or sugar have an effect on the heart is there a

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
