The Truth about the “8 Daily Glasses of Water”

So is drinking an 8-ounce glass of water eight times a day help flushing toxins out of your body.

Two men said “No”.

Two kidney specialists at the University of Pennsylvania, Drs. Dan Negoianu and Stanley Goldfarb, did a research on human water consumption behaviour and found this amazing truth.

The specialists suggest that the water play no part in flushing the toxins out of your body. In fact, kidney is the one part of the human body that does all the work.

Goldfarb reckoned that the whole idea about drinking as much as 8 full glasses of water every day comes from people misunderstanding that if drinking water is good, drinking more is better!

More water is good but only if you are working out or have been losing water from your body due to hot and dry climate or other activities. Else, the fluid that our body requires are already exist in our daily diet.

A study from Institute of Medicine, part of National Academy of Sciences once recommended that women and man should consume average 91 and 125 ounces of fluid daily repetitively. It does sounds like 11 to 16 glasses of fluid all together. But in actual fact, you get more than what you need in your daily diet already; in soup, coffee, soda, soup, and don’t forget 20% of what you need are also in the solid food we eat.

So drink only when you are thirsty because that is the way your body is designed. Amazing but true.

Absolutely drink, when you are thirsty. The problem is that many people mistake thirsty signs (like headache) for other things like need of coffee.

Coffee and soda contain caffeine which is a causes the body to lose water. In other words for every cup of coffee a person drinks that person should drink 2 cups of water to replace what the body loses because of the caffeine in the coffee. A person also loses about 10 cups of water per day through normal activities and that needs to be replaced.

Turns out caffeine being a direct diuretic isn’t true. Google it. A few studies (think recent… most of the web probably still says caffeine makes you pee) have shown that caffeine only functions as a diuretic when large amounts are taken in… and it certainly isn’t a strong enough diuretic to warrant drinking twice as much liquid as the caffeinated beverage. Think about that; why would you need to drink twice as much for a cup of tea (30 mg) and the same twice as much for a cup of coffee (100-200 mg)? Answer: you don’t.

I always feel better when I’m drinking a quart of water every day. Every time I get sick I’ve been dehydrated. I agree that 8 glasses of water is likely excessive. However, based on my experience a few glasses of water every day is far better than relying on soup and soda to keep me hydrated and healthy.

Sadly all of these studies are skewed, as are all of these posts that really only set out to tell people they don’t need to drink that much water.

All of those items you listed that “contain water” also have to be digested and part of that digestion process will use much of the water consumed and sometimes MORE.

You need more than you consume in just foods ESPECIALLY if you actually workout, which basically EVERYONE needs to be doing on a daily basis in some form anyway.

All in all this kind of misleading information is truly damaging to the health and fitness community as it has been completely debunked over and over again.

The kidneys, liver and spleen need something to work with.
Soda is perfectly OK to drink, its the stuff with the sugar and other rubbish that is damaging.
Coffee tastes great, so does tea and wine and a few other beverages, which is why we drink them, is it not.
Drinking eight glasses of water each day doesn’t make sense because often it lacks taste.
Common sense, which isn’t common anymore is all that’s required.

Great points so far but let’s not forget that fluoride levels in water can also be dangerous. Water intake and newly developing problems earlier in life can be attributed to the fluoride content in water.

There is no scientific connection between fluoride in water and “developing problems earlier in life.” Dozens of studies over three decades have tried to find such a connection, and none have done so. None. Zero.

I can’t remember where I read it, and so can’t be given any credibility at all, but as I recall, the rumour about 8 glasses a day came from a study, which was unable to find a minimum but found that the most anyone needed was that much.
