How much water do we need?

A news study shows the "truths" we know about water may not have any scientific basis. Do you push your kids to drink water? I know I do. I don't think this study says that's a bad thing by any means, but it is interesting.

We always hear we need to drink eight glasses of water a day. That may be correct, but there's really no proof. Two doctors from the University of Pennsylvania said they spent a lot of time looking for research that shows how much water we need each day. They found very little.

One researcher thinks, "It's required for life, and I guess that's led people to think, well. it a normal amount is good, then extra might be better."

I remember being told I was getting heavy by my manager at a clothing store in college. She told me to drink more water because it will fill you up and you won't over eat. Doctors say there are no conclusive studies proving this.

What about the idea that water will help your kidneys function by clearing out toxins? Same thing-there is no scientific evidence. There's no proof is will prevent headaches or improve skin tone either.

From ABC News:

"A government panel said unless you're working out or live in the desert, you need 11 glasses full of fluid for women a day and 15 for men. That sounds like a lot, but most people get it already from things like coffee, milk, and soda. In fact, 20% of the water you need comes from the moisture in food. The best advice is to drink water when you're thirsty."

I hope this story doesn't prevent people from drinking enough water. I do think it fills me up. How about you?
