Drinking alcohol may satiate some thirsts, but it definitely will not keep you hydrated. Alcohol is a diuretic, making you urinate more frequently — you know the saying "break the seal"? Drinking too much can lead to a massive hangover headache — especially if you get sick from too much alcohol consumption.
There has been a ton of debate around the subject of coffee actually dehydrating you. While a cup of joe a day won’t harm you, if you are a coffee addict, you might want to balance out your consumption with a ton of water. Not only is coffee a diuretic, but its caffeine could aid in speeding up dehydration, too.
We all know that soy sauce is salty, but did you know that too much of it could be deadly? In June 2013, a young teen guzzled about a quart of soy sauce and nearly died from an electrolyte imbalance called hypernatremia, which occurs in dehydrated seafarers when they run out of fresh water. While you aren’t going to down a quart of soy sauce (...right?), using it frequently can cause mild dehydration.
It is no secret that fried foods aren’t good for you — just consider this another reason you should avoid them. Consuming too many fried foods can dehydrate you, as many fried and processed foods contain a hidden amount of salt, causing you to easily go over the 1/2 teaspoon daily salt intake recommendation.
Drinks high in sugar create an acidic environment in the body, impeding enzyme function and straining the kidneys. This basically means that while sugary drinks may quench your thirst initially, the sugars and artificial sugars are siphoning out your body’s water storage by making your organs work harder to process them.
