Just what really is good nutrition??

That ammount of water is really bad for you. Also, try spreading out your meals to about every three or so hours instead. You don't want to overload your digestive system too much. You're eating a good veriety of foods though.
Losing water happens but not at that rate. Your stomach can really only absorb 500ml or so an hour. Drinking 15 pints a day seriously depletes your electrolytes and is pretty damn dangerous!
As for your sweat. Imagine getting a skooshy bottle that holds a pint of water. think how wet you could get spraying yourself with that fine mist. thats what sweating is like. even if you drip a lot you wont lose overly much sweat as your body has to draw it from the blood and tissues to sweat it.

This is from a while back but...

well me/both my tutors/both fitness instructors at my gym, find that the average joe does not understand technical terms, and that this is made very clear -also research shows that people generally dont ask the questions, they instead act like they know what your talking about.

within a couple of months nearly all of my clients are asking about neutrition and know the names ow what they are needing. Electrolytes are one of the first things that I cover when training a client as it's very important to fuel your body correctly before/during/after exercise. It's the rest and correct neutrition that helps you recover stronger. If you dehydrate by 5-10% your performance goes down dramatically. You should always be fully hydrated during exercise for safetys sake.

Glycemic Index is how sugary a food is.
It's all about eating low sugar food and high amounts of starchy carbohydrates. People think that you need sugar in your diet but you don't really need that much if you chew your food well. The reason you don't need that much sugar is because a chemical called ptylin in your saliva changes more complex carbohydrate (starchy foods) into simpler carbohydrates (sugars).
If you're training hard though it's always a good idea to have a weak sugar and salt solution (isotonic preferrabley) for the purposes of better and faster replacement of your electrolytes in your blood (salt and sugar levels). Viper if I remember correctly is a good drink for this.
Eating a low g.i. diet is really just eating a diet with low sugar content.
