I know there have been people on here saying that drinking X amount of water a day helps the brain with complicated reasoning and math. But no one has posted an links to scientific studies or documentation as to where these reports came from. If you have such information, could you please post it for me so I can read about it. In the mean time, I am hunting on the web. Thanks
well, i am taking a (required) health class at school right now... a quote from my book:
Water is the major component in both foods and the human body: you are composed of about 60% water. Your need for other nutrients, in terms of weight, is much less than your need for water. You can live up to 50 days without food but only a few days without water. Water is distributed all over the body, among lean and other tissues [...] Water is used in digestion and is the medium in which most of the chemical reactions take place within the body. [...] The foods and fluids you consume provide 80-90% of your daily water intake [...] To maintain a balance between water consumed and water lost, you need to take in about 1 milliliter of water for each calorie you burn - about 2 liters, or 8 cups, of fluid per day - more if you live in a hot climate or engage in vigorous exercise.
oh yea, the water in your coffee does not count. to further answer you question... if you do not take in enough water, then you start to become dehydrated. one of the symptoms of dehydration is "darkend urine color..." gross, yes, but it is a good indicator. you should drink enough water so that your urine is clear or lightly colored. not enough water (H2O) in the body means (indirectly) not enough oxygen, which is necessary for the brain to function properly.

I also gave up pop a while ago. I still srink like 1 can a day, but i used to drink like 2 or 3 litres a day. So basically thats cutting it out. Oh yeah and coffee sucks. Drink a nice herbal tea instead, much better tasting.
