A) When you have to go to the bathroom about every 30 minutes
B) When your urine is clear enough to read through
C) When your urine is odorless
D) When you feel slightly bloated all the time
The correct answer is B.
The purpose of urine is to get rid of waste, like nitrogen, through urea, Dr. Oz says. Clear urine means that you've gotten enough fluid to wash it all out. "If you can't [read through it], that means the urine has been concentrated a bit," he says.
Water is important for more than just flushing waste out of your system. Dr Oz says it also allows chemical reactions in your body and helps blood reach capillaries to bring in more nutrients.
"Not having enough water gets the whole system to become sluggish, including your bowel," Dr. Oz says. "One of the best solutions I have found for constipation is water, just because you can mix it up a little bit and get it going."
