Wow! First off, thank you for all of the very well informed responses!

I had no idea there was so much to be known about eating better, and why we eat the way we do, especially with regards to carbohydrates.

I should probably add that it's not just bad carbs I'm out to cut. I want stuff like steak/bacon/pepperoni pizza/nachos/taco bell all the time, and I know that with my genes it's only a matter of time before that sends me to the hospital.

Also, I'm quite skinny at the moment, apparently regardless of what I eat...so I'm not sure if that's a sign of a contributing factor

Again, Thank you so much for the information!
