what to eat?

Well, i did my "subitos" today, and i think that without tiba's advice, i worked a little too hard and my knee is a bit sore. I'm not too concerned, though... i am sure it will feel better by tomorrow. My times were 1:31-1:29-1:25-1:33-1:25-1:26-1:29-1:25-1:26-1:19. I also did 1 slow mile to warm up, and 1 slow mile to warm-down.

I have been thinking a lot about running nutrition recently. i wonder if i would run faster if i weighed about 5 lbs less (i don't think it would be healthy to drop much more than that), and if so, how do I do that without jepoardizing my health during training?

Sometimes I spend so much time wondering if i have eaten enough for a run that i eat too much, or that I drink too much and then feel bloated. Runner's World wasn't very helpful in my quest for understanding. They have several articles about other nutrition issues, but I still don't know what to do. I guess my instinct will have to guide me on this one. I already eat nearly 0 processed/packaged foods, almost 0 trans fats, and I have a basic understanding of the idea that "simple is better." But then i saw a video clip of a dude training kenyan guys. He says that after a hard run, they eat watermelon and a protein drink. THAT'S IT? After miles and miles in the hot sun??!! I always eat more than that, and I'm sure i'm not training as hard as they are. And anyway, I wonder where i can buy protein powder here...
