Riley, I'm doing this in the nicest way possible...

But... you can use Google for these questions. It exists for a reason.

I was thinking that but to be fair if you don’t quite know how to phrase a question because the entire area is new to you asking can be easier.

You need hydrogen atoms from water for the Kreb cycle in metabolism. It’s how cells make energy from the organic molecules we eat.

That’s the short answer.

Interesting. Thanks for the response!

Indeed. Especially since I’m not very familiar with the hard sciences. I enjoy reading the responses, regardless…..

So did it pass through a lot of other humans and animals previously? It might have, or maybe. But is there anything remaining from those other humans or animals in the water you're made up of, or the water you are consuming? More than likely never, more than likely. Not other than it's basic atomic elements more than likely. Which are all always the exact same at that level fundamentally.

God Bless.

Thanks for the response!

God bless you

Is anyone here an expert of digestion and digestive health? How does water help digestion?

The gastric acid is water solution. Additionally, water helps gut bacteria to multiply and metabolize food which helps in digestion. In basic terms, water not only helps but essential part of digestion process.

But if you're asking if you need to drink insane amounts of water to get proper digestion, you won't get one answer to that.

While doctors say you need to drink 2 liters of water a day. Scholarly research articles in NIH PubMed will tell you that humans can healthily adapt to much lower quantities of daily hydration without any ill effect and these adaptations can be passed down to offspring.

My dad drank less than 1 glass of water each day. I drink even less and only 1/4 glass if I didn't exercise. With exercise, the quantity can range from 1/2 glass to 1 glass of water each day.

I get most of the needed fluids from food and sweet beverages which is not a lot. My total fluid intake would be 2.5 to 3 glasses each day even when accounting for exercise and even when I'm already drinking whenever I feel thirsty. It's very little but I experience no issues with digestion and my metabolic efficiency is at athletic levels.

I don't recommend this practice. We're just quite adapted to very little water intake.

Passed down to your offspring? Are you invoking Lamarkian inheritance? If you are merely suggesting an epigenetic response. please provide a link to the relevant research.

I have kidney issues so I drank a large amount of water daily.

I can't find the exact research anymore but found two different links.

One concerns pregnancy which isn't surprising at all. The other through males via sperm.

I'm not recommending cutting down on hydration. My relatively high volume of exercise and healthy BMI (at the low end) is likely preventing symptoms. I only drink when thirsty but I seem to have unusually high thirst threshold. I don't drink through a skating marathon in hot and humid climate. No symptoms of dehydration at all. It can get bad if I drank while running a half marathon.

These forums aren't as busy as they were years ago. Probably best not to dissuade people from making new threads about whatever they want to talk about.

This place used to really hop.

Maybe it will get busy again one day?

Anyway, back on topic.

Yeah, and the general quality has dipped. There used to be some right corkers for threads not even five years ago.

Depends on who's doing the judging.

Interesting you can tell what's right and wrong in today's current science papers, but are a deist.

Very interesting indeed.

Considering most current threads seem to be post and run jobs with no serious engagement from the poster, I'd call that a dip.

That... really has nothing do with what I said.
