I find that I must limit my intake of high nitrate foods. I don't understand the implications of it yet.
Which specific foods, and why?

I wouldn't assume that the problem is fixable.How did you fix this problem for yourself?
If mankind was so fragile that a change in diet composition was enough to kill us, I don't think we would have made it as a species. I think it was common for our ancestors to eat vastly different diets from one month to the next. You eat what is available on a given day or week. You are ketogenic one week, eating 80% fruit the next week, eating mostly protein and fats when you catch some fish, etc. That kind of metabolic flexibility must be hard wired into our species, and it explains why we have so many metabolic pathways for creating energy. The body has to be able to adjust to such things, and it cannot be so fragile that it requires a specific balance of carb/protein/fats to survive.
Do you have a link to her claim that CFS patients are alkaline at rest?
Another aspect of 2,3-BPG metabolism that had not been fully explored was whether the rate of metabolite flow through the 2,3- BPG shunt is biologically important. In by-passing phospho- glycerate kinase the shunt allows the metabolism of glucose without net production of ATP. In other words, the extent of flux through the shunt relative to the flux through the main glycolytic pathway will affect the glucose ATP stoichiometry which could vary from 0:1 to 2:1. Thus it has been suggested that the 2,3- BPG shunt `uncouples' the supply of NADH from the pro- duction of ATP [23] NADH production is particularly important in erythrocytes because it serves to maintain Hb in its functional Fe(II) state by acting as a cofactor in the reduction of met- haemoglobin (Met-Hb) [Fe(III)] by NADH:Met-Hb reductase.
The biggest and most rapid acidifier of urine is inflammation/allergy. I knew a woman with migraines who used her allergy to corn to successfully treat her migraine attacks. The early (prodromal) state for migraines is alkaline-anaerobic-anabolic stress, which shows in non-inflammed individuals as an alkaline trend in the urine which reaches an alkaline threshold (a different pH reading in each individual), at which time prostaglandins are produced to quickly acidify the body/blood stream and produce the full-blown migraine symptoms.
Prostaglandins are involved in several other organs such as the gastrointestinal tract (inhibit acid synthesis and increase secretion of protective mucus)...
With regard to 2,3 bisphosphoglycerate, there was an interest in this in the late 90s but repeated testing (probably unpublished) could not confirm a deficiency. If this is normal then lactic acidosis is not present. In fact, privately, I was informed that repeat lab testing shows high 2,3bpg, which indicates alkalinity not acidity. However as a marker this is a time average .. it indicates (indirectly) average blood pH . Spot pH will depend on activity, and the activity we use to get a test done may make us acidic. So only in a fully rested state will we get to see alkalinity, and even then not until a while after activity stops.
We will indeed produce lactic acid, but its not that we are stuck in glycolysis but the Krebs cycle cannot ramp up to meet need. Why this is happening is still being debated and investigated. There are lots of theories, and most have some evidence for them. It may also be that several theories are right but its combinations of things or right for different subgroups.
At rest though, in milder patients, we should not see much lactic acid in blood. Now, we might in spinal fluid if our brains are being pushed. In exercise we can expect huge rises in lactic acid.
I first got interested in this line of research in the 90s. Its been looked at for that long. However a decade and a half of testing has failed to find the cause.
All bets are off for the severely disabled with ME. Just surviving might push them in to lactic acid overload. They are the people most at risk.
This table lists many triggers for lactic acidosis:
Hypoxia and carbon monoxide poisoning have both been considered in ME.

(This paper is not very readable, but this comment comes from the intro.)
The shunt is a name for the pathway in which 2,3 BPG is synthesized. It is also known as the Rapoport Leubering Cycle. It is primarily active in red blood cells. I am unsure it makes much of a difference in other tissues. If it disturbs NADH metabolism then it might mean our blood NAD/NADH ratio might not reflect our tissue NAD/NADH ratio. What is more clear is that the NADH/ATP or NAD/ATP ratio in the blood might be disturbed.
What is of interest here is that any form of hypoxia/anoxia might result in these issues, and that includes a bad NAD/NADH ratio as a possible cause out of maybe hundreds of possible causes.
Since there are a great many factors that can cause this, it may be that we are a population with a range of different issues but similar final result. Or it may be that a combination of factors might drive this, and that combination might vary slightly patient by patient.
This last view is the one I favour ... we know of many risk factors, and some like B12 deficiency, EDS and small fiber polyneuropathy may indicate problems with the regulation of peripheral vasculature, resulting in local tissue hypoxia. I am currently of the view that many factors combine to induce final pathophysiology.
Sorry everyone for the cross-talk and for going a little off-topic (it's all related after all...)
I never got sustained benefit from probx. I feel that both prebx and probx are immunostimulants and harmful to me right now (trigger inflammation).
Maybe, in a large controlled study. As an individual, how do you tell what is due simply to activity? Exercise produces heat anyway. To use temperature as a measure would, I think, require many samples and statistical analysis.I wonder whether I could deduce anything from taking my temperature before and after exertion. I'd need to have the thermometer ready, as when I get exhausted and hot I have to sit down! Would an oral temperature reading pick up any temperature change?
My own prebiotics are food. I don't take prebiotic supplements. My vegan diet should provide plenty.
Celery, beets, lettuce, herbal teas. I feel like I am suffocating if I overdo with them (especially around the thymus and the glottis). I eat them regularly, but small amounts at a time.Which specific foods, and why?
And I doubt the healthiest ones would live more than 30 years. With my SNPs and lifestyle, my real problems only started at 42.Sickly people with fatigue who couldn't keep up with the rest would have likely died very quickly anyway.
In my defense, several months ago I bought a rebounder and could only use it for about 3-4 times for no longer than 30-40 seconds.How about if I throw in the phrase "[something] Benefits PEM"? (get it?)
-by microscopeHow does [rouleaux] get diagnosed and what is the consequence?
you can look for gums bleeding, or easy bruisingYeah, I am probably taking on some risk by thinning my fibrin without knowing what to test later to track effects.
hypercoaguable blood would be a risk in Coronary Artery Disease (plaques, e.g) or Cerebral Vascular Accident (stroke) -- then also DVT, claudication (leg pain from blocked arteries), etcCan you explain the other comment about non-CAD non-CVA danger?
I'd guess you'd want PT PTT INR or whatever, That's beyond me.The thing is, I don't actually have proof that I am hypercoagulable do I? There was no bleeding study done for me. What was done was a sedimentation rate test, and this is normally used to assess inflammation. If the blood is not viscous and particles fall through quickly, this is a marker of high inflammation. My blood was at the far end of the other range, which one osteopath commented meant that my blood is "thick". That's not the way the test is normally used probably.
There are the POTS people and others who would get more syncope from more NO mediated vasodilation --> lowered BP.For NO to be harmful
Dave Whitlock says ME/CFS has low NO, whereas Prof Martin Pall says the opposite, that ME/CFS has high NO (and high peroxynitrite).
I have an idea that they both might be right:
To fight an infection, the immune system may generate a hell of a lot of NO via the iNOS enzyme, which is secreted by the immune system. For antimicrobial purposes, iNOS pumps out NO at levels 1000 times higher than the NO generated by the other two NO enzymes, eNOS and nNOS.
So my idea is that when iNOS is at a high level on a long term basis (as a result of fighting the chronic infections found in ME/CFS), after some time the body might up-regulate the processes that break down iNOS, to ensure blood levels if iNOS-generated NO don't get too high. These processes that break down iNOS may then start breaking down eNOS (which makes NO for vasodilation) and nNOS (which makes NO for neurotransmission) as well. So what may happen is that high levels of iNOS may inadvertently cause a reduced levels of eNOS and nNOS.
Either that, or the chronic high levels of NO generated by iNOS may cause epigenetic changes that down-regulate the gene expression of eNOS and nNOS, so that you don't get sufficient NO made for vasodilation or neurotransmission.
So in summary, my idea is that the chronically high levels of iNOS might conceivably have a paradoxical effect of lowering eNOS and nNOS.
Anyway, this is how I speculate ME/CFS may involve both high NO in the areas of infection, and low NO everywhere else. Just an idea.
Note that asymmetric dimethylarginine (ADMA) and N(G)-monomethyl-l-arginine (l-NMMA) are the body's inhibitors of the NOS enzymes. ADMA levels are increased in patients with fibromyalgia. 1
How about a book from a Nobel Prize winning co-discoverer of NO, Louis Ignarro?Looks like I could do with something that boosts nitric oxide.

Arginine, Citrulline, maybe also Mg. Probably won't work, though. I see he also has a newer book now.
What are the other details about your NOS3 SNP? The letters, amino acids, etc.
