How does caffeine and sugar effect your heart and brain?
There are obvious negative effects of sugar, but really only on the heart. Your brain on sugar is much more hyper active. Your neurons fire faster, and cause messages to be sent quicker. The reason there is a crash after eating a lot of sugar is because of a waste product of your neurons firing. The waste product is called Adenosine. Caffeine works by inhibiting Adenosine receptors which cause you to sleep. If you take sugar and caffeine together, you get hyper, with a slower crash rate than if you just had sugar. You can find out more about all of these things (sugar, caffeine, and adenosine) on sites like wikipedia, or more trustworthy sites...
