"All of us have the exact same percentage of salt in our blood that exists in the ocean."
Sounds like a quote from GW Bush. Who could believe this to be true? Is it an Urban Legend?

Never heard it before, but it is obviously ridiculous. If true...we would be able to drink seawater, which is of course dangerous. Sea water on average is about 3.5% sodium. Salt in the human body makes up about .15 percent by weight, and about 1 percent of water.

I actually saw a program about that years ago. It had something to do with the development of a human embryo and something about the salinity of something or other. So, yes, there may be something to it.

Actually, the percent of salt in our blood is the same as the salinity of the ocean a few millions of years ago, but since the difference is small, the statement that our blood has the same salinity as that of the ocean is close enough.

I had heard that, years ago and thought it true. Further research indicates that seawater is about 4 times saltier than blood. Roughly 3.5% vs 0.9%

Maybe it means we have the same percentage of saline as the salt water of the ocean.Salt is essential for life - you cannot live without it. However, most people simply don't realize that there are enormous differences between the standard, refined table and cooking salt most of you are accustomed to using and healthy natural salt. These differences can have a major impact on your staying healthy, or increasing your risk of diseases you want to avoid.. If you want your body to function properly, you need holistic salt complete with all-natural elements. Today's common table salt is poison that has nothing in common with natural salt. Your table salt is actually 97.5% sodium chloride and 2.5% chemicals such as moisture absorbents, and iodine. Dried at over 1,200 degrees Fahrenheit, the excessive heat alters the natural chemical structure of the salt causing the potential for a myriad of health problems in your body.

I heard this all my life too but never questioned this it probably a Urban Legend~

"Interestingly, the proportion of minerals and salts in human tissue is very similar to the composition of seawater. The adult human body contains enough salt to fill about three salt shakers, but the salt is constantly lost through bodily functions like sweating, crying, urinating, etc. It is essential to replace this lost salt, but not to over-replace. We can't tolerate seawater consumption. Our cells can't take it and our kidneys can't take it." - http://www.straightdope.com/columns/read/2131/what-would-happen-to-you-if-you-drank-seawater . So it looks like it is one of those facts that gets truncated - simplified from tissue to blood - and then passed on.
