Typically, excessive vomiting, fevers, sweating, and urination are the chief causes of dehydration. But what many people don't think about is the fact that certain foods and drinks can cause severe dehydration as well. For instance, a smidge of soy sauce is fine, but did you know that a teen who guzzled about a quart of soy sauce nearly died from an electrolyte imbalance called hypernatremia, which occurs in dehydrated seafarers when they run out of fresh water? Or that too many cups of coffee could end up leaving you light-headed due to coffee's natural diuretic and caffeine properties?
The problem with the internet is anyone can post nonsense like this as if it is fact. Perhaps if the author had posted about his/her experience and given an opinion rather than a declaration of truth it would be less damaging. I suggest you and anyone interested searches for some peer reviewed literature on the subject before making an assertion. To begin with, I would do some research on caffeine. That “mild” diuretic effect, which you claim has the same effect on the body as water. Do a little research on caffeine half life. Perhaps then you will begin to see it has more than just an instant effect. It can last for up to 12 hours, which absolutely causes the body to lose more water than is gained by your standard can of sugary soda. You also make no mention of refined sugar’s disruptive effect on metabolism and digestion which is linked to the subject at hand. Nor do you note the mind altering effects of caffeine, which play haywire with a lot of the bodies system. Please do some proper research in future before posting dangerous and misleading articles. It’s people’s health you are screwing with here. Not just your own.
