Yes. I worry about Mike, to tell the truth.
Thanks for sharing your knowledge and links, both of you!
Yes. I worry about Mike, to tell the truth.
Mike,
The article to which you link describes two specific serious conditions where treatment with bicarbonate may be necessary. The first is the condition of extreme metabolic acidosis where the normal buffering system in blood is already overwhelmed (note the blood pH described as 7.2). This is a very serious illness and further drop in blood pH will occur quickly and will probably be lethal. Therefore intravenous bicarbonate is given to restor the buffering capacity of the blood to compensate for the uncontrolled acidosis.
The second instance is a condition where the buffering capacity of the blood is nearly overwhelmed, and soon will be. Here again, intravenous bicarbonate can be lifesaving.
These are immediately life threatening conditions caused by severe metabolic acidosis. I will venture to guess that you do not know the difference between metabolic and respiratory acidosis, or alkalosis, and I do not have the time to provide a free on-line physiology course.
The normal blood buffering system prevents deviation of blood pH very far from 7.4, as many have told you in this thread. Deviations of blood pH can occur, are serious illnesses, and can cause serious harm.
Consuming small amounts of Na bicarbonate orally will not significantly deviate the blood pH because of the buffering system, and the excess bicarbonate you eat will be degraded and excreted to maintain balance.
However, the result of consuming too much oral sodium bicarbonate can be not good:

Please be careful with your own homespun remedies. Medicine and physiology are extremely complex, and that is why physicians train for many years. Your misunderstanding of simple acid-base physiology should be a warning to you that, while intelligent, you do not have the appropriate background to fully comprehend the complex issues involved in cancer diagnosis and treatment. If you do have cancer, then you need an oncologist to help diagnose and treat you.
Because he publishes papers on how bicarbonate might be useful as part of cancer treatment.
That is not what I see in your writings. You argue that transportation of bicarbonate into cancer cells is damaging them - not helping them survive.
Looks like you already found literature on glucose transport across cell membranes. No need for me to repeat those.
Here is one you should try and get from your library. Figure 3 illustrate quite nicely how cancer cells eliminate acid (H+), including the use of bicarbonate, which is transported into the cell through its own transport system, and not alongside/bound to glucose.
It is a bit more complicated than that. I'll try and simplify things a bit. It has to do with the Warburg effect (Sometimes glucose is not fully degraded in spite of presence of oxygen, resulting in production of lactic acid instead of CO2 and H2O). This effect is prominent in many/most cancers. It is because of this effect that sugar uptake is useful in detecting cancers through PET-scans.
Here are a few examples of what complicates things a bit:
1) Cancer cells don't metabolise glucose through the Warburg effect only. There is evidence that some cancer cells also use citric acid cylus and oxidative phosphorylation.
2) Sometimes the warburg effect takes place in normal cells which are part of the cancers, providing molecular building blocks for the cancer cells.
3) The Warburg effect may also take place in normal cells.
But have you read articles demonstrating a chemical reaction between glucose in molasses and bicarbonate resulting in a chemical bond?. Since writing the post I am responding to, you have read about glucose transporters (The GLUT's). And you may have already started looking into bicarbonate transporters. This should enable you to look critical at the claim that glucose is chemically bound to bicarbonate, and this compound is then transported by the blood to cancer cells etc.
We are all susceptible to self delusion. And self delusion is a powerful convincer. This is why controlled experiments are necessary.
Here are trials on flaxseed and cancer registered on clincaltrials.gov.
And here are some where bicarbonate are part of the experimental treatments.
Thanks for sharing your knowledge and links, both of you!
!). Luckily he may have done this short-term (a couple of days?).
