Comment on It's basic science

  You know what’s better than water when you need water? Nearly everything that isn’t alcohol or literal piss.

  I mean it really depends on the person and their current condition. The article you linked kinda has an abstract definition of hydration that doesn’t take into account things normally associated with dehydration.

  If you are working hard outside and are mildly dehydrated I wouldn’t recommend slamming down a sugary soda with caffeine. Excessive sugar is diluted in the intestines which can cause further dehydration, and caffeine is a diuretic.

  Normally this wouldn’t really matter, but if you’re already dehydrated it can make the situation worse.

  Water is great, it may not be the most effective hydrator in the world as it doesn’t have the electrolytes and sugars that something like Gatorade has. However, it’s the best thing for your overall kidney and liver health which is what really matters. Most Americans already have an excess of salt, fat, and sugar in their diets, so even after working outside and sweating your ass off you are probably better off just having some water.

    No, it won’t. That’s the point of the misconception. You even get to it later then dismiss. We aren’t taking about overall health. We aren’t talking about the 'betes.

    1. None of those things will dehydrate you more despite people saying differently. Not soda, not milk, even beer under 2% beer will be better. You will be rehydrated, there WILL be a net gain of water in your body. There is no net loss of water no matter how much people say sugar or caffeine will lower the net gain.

    2. If you’re dehydrated, you’re lacking salt. There’s a reason why physically demanding companies provide free drink packets to their crews. They don’t want road crews dying by the side of the road because they slammed water and had no salt on a 100 degree day working next to a machine shooting out molten tar and rock.

      I mean, whenever you are talking about health you always consider total outcomes. The articles you are linking are talking about a very specific type of dehydration.

      None of those things will dehydrate you more despite people saying differently. Not soda, not milk, even beer under 2% beer will be better. You will be rehydrated, there WILL be a net gain of water in your body. There is no net loss of water no matter how much people say sugar or caffeine will lower the net gain.

      “Beverages with more concentrated sugars, such as fruit juices or colas, are not necessarily as hydrating as their lower-sugar cousins. They may spend a little more time in the stomach and empty more slowly compared to plain water, but once these beverages enter the small intestine their high concentration of sugars gets diluted during a physiological process called osmosis. This process in effect “pulls” water from the body into the small intestine to dilute the sugars these beverages contain. And technically, anything inside the intestine is outside your body. Juice and soda are not only less hydrating, but offer extra sugars and calories that won’t fill us up as much as solid foods, explained Majumdar. If the choice is between soda and water for hydration, go with water every time. After all, our kidneys and liver depend on water to get rid of toxins in our bodies”

      From your own article…

      If you’re dehydrated, you’re lacking salt. There’s a reason why physically demanding companies provide free drink packets to their crews. They don’t want road crews dying by the side of the road because they slammed water and had no salt on a 100 degree day working next to a machine shooting out molten tar and rock. We aren’t pumping people’s blood full of sterile water. Saline bags are .9% salt for a reason.

      Again, you are talking about a specific type of dehydration… hyponatremia is exceedingly rare and is usually a sign of an undiagnosed kidney disease. Your nephrons will usually regulate your thirst in conjunction to the available salts in the body.

      Dehydration is not just a lack of salt, it’s an imbalance of salt. Meaning that you can just be low on fluid with too much salt available.

      "Unsurprisingly, the ad is sponsored by the milk industry. And while I’d never heard this claim before, the studies behind the idea aren’t particularly new or compelling. "

      Finally, the main benefit of water is that it’s neutral. The reason why people don’t tell you to slam a glass of milk or soda if you’re dehydrated is because it can upset your stomach. When concentrated amounts of sugars or fats enter the intestine the dilution process can go overboard and cause diarrhea, which can dangerously dehydrate you further.

      Hydration is more complicated than what you are alluding too. Simply stating everything but piss and liquor is better than water is just ridiculous and misleading. In specific scenarios other liquids may provide some advantages, but it’s highly reductive to make that claim so broadly. Especially considering it requires you to separate hydration from kidney health, you know the things that control your thirst in the first place.
