Why is Time Machine backing up nearly a Gigabyte every time?

I have an external Hard Drive which I use to backup my MacBook Pro. Every single time it backs up it has to copy just shy of a gigbyte of files. I have no idea what is causing this as I have all of the regularly changing folders exempted from the backup (eg, my Downloads folder, Trash and Caches). What on earth is accumulating 900 Megs of change per hour? When I'm not doing anything other than browsing the web?
