Water is an essential molecule required in many basic reactions within the body such as hydrolysis reactions and cellular respiration.
I read in one of my college classes (either bio or chem) that pure water, pure H2O, is bery poisonous. There needs to be some impurities in to to make it drinkable.
Water = Life. Thats how fundamental it is. I can't even begin to talk about its necessity. You know how important oxygen in the earth's atmosphere is for human life? Well water is more important than that.
btw, you don't get diarrhea from drinking too much water alone. You get diarrhea from eating bad food or drinking BAD water. Your body regulates the amount of water through renal filtration and urination. You don't crap out excess water. Pretty much every vital process taking place in an organism involves water. From thermoregulation, blood pressure, down to every little facet of the net that makes us living creatures. I know the meme about 3 days is intended to be hilarious but that should speak volumes. Your body will go haywire after a little over a day and you will survive probably 4-5 days depending on enviornment and other factors. Food? The type of nutrients you are looking for? You can survive without "Food" for even a month.
What are you defining as a nutrient btw? Is a nutrient something like glucose or a fatty acid you use to generate energy? Vitamins are considered "Nutrients" . Vitamins act as catalysts and prosthetic groups for vital reactions that take place in the body. Don't confuse the meaning of the word "Nutrient" in this case.
Again, you are completely wrong. Water itself will not give you diarrhea, that's just ridiculous to think that. There are other things in the water or food they ate that gave them diarrhea. You would have to drink so much water you'd want to vomit to give you diarrhea and even then your body would probably absorb it and make you piss it out. Water by itself has no nutrients...none. But water helps to dissolve other nutrients that allow them to be absorbed into the cells and carry cellular byproducts out of the body. Water is necessary to maintain proper electrolyte (cue Brawndo clip) balance in the body, blood pressure, and maintain good kidney function. If you want to find out the importance of water and you're having trouble with the google machine, search for "dehydration". Water is the medium that allows all the other vitamins, minerals, amino acids, organic compounds, etc...to do their thing. Without an abundant amount of water your body would not be able to function and you die. And technically water is a compound not an element. Chemically bounded elements make a compound. Oxygen and Hydrogen are elements.
Hmmm, not sure about that. It doesn't seem like it would be. Water is water, whether it has some dissolved minerals in it or not doesn't change its chemical make up. Either way it's definitely not "bery poisonous".
You couldn't drink enough water in a day for you to actually tax the kidneys and even if you did tax the kidneys that indicates other issues.
The reason people are against distilled water is because it doesn't contain any minerals. Over time you would develop insufficiencies. this. more water is actually better for your kidneys, the amount of crap they filter out necessitates that they get a good cleaning as well.
Should you drink water right after eating a meal? I remember there was a thread about that a year or two ago.
