Everyone has their own ideas about what is good for you. Here's what I think, in general.
The less processed food is, the better. Meat is good to eat a few times a week, not everyday though. Organic meat is higher quality.
I avoid dairy. I try to eat a lot of fresh vegetables, whole grains, and fruit.
To drink, I usualy have water. Juice I will drink in the morning, sometimes.
My pet peeve is soda, I hate the stuff with a passion. Soda companies are pretty much on par with cigarette manufacturers.
