Does Alkaline water leave an acid 'ash' in the body?

Question

If we drink a glass of water with lemon added, although the lemon is acid, health people say it makes our bodies (at a cellular level), more alkaline by leaving an alkaline 'ash' - so then, what does alkaline water do to us? I see lots of companies selling drops that turn your drinking water to p.H. 9 - but surely if the acidic lemon has an alkaline effect, does the alkaline water have an acid effect on our bodies?

Answer 1

No, no, no. You're thinking too simplistically of the situation.

Actually, although what the first guy said about BS claims is *generally * true, in this case it's not BS. Citrus juices do have an alkalinizing effect, but you need to understand why. The acidity is from citric acid and other organic acids.Citric acid may also be present as monopotassium citrate. When it enters the body, it seperates into K+ and citrate ions. Citrate ions enter the mitochondrial Krebs cycle and combine with H+ to form CO2 and H2O after a complex series of reactions. CO2 is of course eliminated through the lungs.

Meanwhile, that leaves OH- ions that contribute to increased basicity of the cell solution (charge balanced by K+). However, you would need a LOT of citrus or other fruit juices to make an impact since our bodies are well buffered.

The opposite like you asked is not true. For that to happen you would need a salt containing a metabolizable organic base and an inorganic acid, which rarely, if ever, occurs in food or drink. Alkaline water has salts like calcium bicarbonate which are totally inorganic and cannot be metabolized into CO2 like citric acid. Therefore, alkaline water is alkalinizing.

Answer 2

Whoa!!! I haven't heard this big of a line of BS in a long time!!! First off, you need to check your sources for this "info" you've been getting. Where are their numbers? Have there been any studies on this that have been replicated? Beware of stories that sound too good to be true. Pseudoscience is VERY insidious and can sound better than the real thing many times! Second, you need to know how to search in real scientific journals and research articles to get the straight dope. Ok, that said, here's my answer...

There is no way for an acidic water to turn you alkaline. Acidity is only, and I repeat, only having to do with the amount of free H+ ions there are floating around in the solution. Basicity (or alkalinity) just means there's a greater amount of OH- ions than H+ ions. These companies you mention who sell drops "to make your water more alkaline" are selling you snake oil in a different disguise. As for your example of lemonade, a lemon has so many things in it it's mind boggling. There's the acid(s) you are aware of, then there are sugars, salts, proteins, oils, minerals, vitamins, etc. Some of these components may have an alkaline character when isolated in a laboratory but the lemon as a whole, is acidic, mainly due to the citric acid it contains.

Hopefully this helps you watch what you believe when you hear a story or anecdote of a product that makes outrageous claims. In general, any product that claims to do something magical "at the cellular level," you should probably run away screaming. :)

i'm quite finding forward to this Ashes series and actual have not thoroughly written the Aussies off. in spite of this England ought to bypass into the series as overwhelming favourites via contemporary style and the actuality that the series is being performed in England. I reckon Chris Rogers may be purely a sprint a gloomy horse as he knows the situations over right here particularly plenty. stable to work out some friendly banter flying around between the two gadgets of supporters too!
