TI - Urine pH is an indicator of dietary acid-base load, fruit and vegetables and meat
intakes: results from the European Prospective Investigation into Cancer and
Nutrition (EPIC)-Norfolk population study.
PG - 1335-43
AB - Evidence exists that a more acidic diet is detrimental to bone health. Although
more precise methods exist for measurement of acid-base balance, urine pH
reflects acid-base balance and is readily measurable but has not been related to
habitual dietary intake in general populations. The present study investigated
the relationship between urine pH and dietary acid-base load (potential renal
acid load; PRAL) and its contributory food groups (fruit and vegetables, meats,
cereal and dairy foods). There were 22,034 men and women aged 39-78 years living
in Norfolk (UK) with casual urine samples and dietary intakes from the European
Prospective Investigation into Cancer and Nutrition (EPIC)-Norfolk FFQ. A
sub-study (n 363) compared pH in casual samples and 24 h urine and intakes from a
7 d diary and the FFQ. A more alkaline diet (low PRAL), high fruit and vegetable
intake and lower consumption of meat was significantly associated with a more
alkaline urine pH before and after adjustment for age, BMI, physical activity and
smoking habit and also after excluding for urinary protein, glucose, ketones,
diagnosed high blood pressure and diuretic medication. In the sub-study the
strongest relationship was found between the 24 h urine and the 7 d diary. In
conclusion, a more alkaline diet, higher fruit and vegetable and lower meat
intake were related to more alkaline urine with a magnitude similar to
intervention studies. As urine pH relates to dietary acid-base load its use to
monitor change in consumption of fruit and vegetables, in individuals, warrants
further investigation.

Goodandevil, if the urine pH is alkaline, at 8, is there anything one should be worried about? If the context is that the subject where urine is obtained from, is on a heavily fruit diet (all sugar coming from fruit and honey, and no carbs)? Calorie-wise, sugar is 40%, oil is 30%, and protein is 30%.

Ray says that urine is has to be acidic, because the blood has to be basic, and that's because the cell has to be acidic:

It's Rainmaking Time - Energy Protective Materials (June 14)

KG: Don’t you find, Dr. Peat, that’s very confusing for people? This man that I interviewed years ago who’s passed on now, David Webster, who did a huge amount of research for like 35 years on the colon. One of the things he said to me is that people talk about pH, but there’s blood pH. The colon has a totally different pH. There’s different pH’s in the body, so how do we not get it all confused?

RP: If you think of the flow of CO2, for example, the healthy cell producing a lot of CO2, which is a Lewis acid – it contains no protons but it has an acidic reaction all by itself – it being formed, and oxygen which forms it. Oxygen is named as the acid former, the acid that it forms is in the cell CO2. So the function of oxygen is to make the carbonic acid, which gives the cell in its healthy condition an acidic reaction below 7pH. When it gets sick and can’t make CO2 – as in cancer – the pH of the cell becomes alkaline. But in the healthy condition, you have inside the cell a mild acidic condition, as the CO2 drags minerals out of the cell and drops them in the blood, the blood becomes alkaline. But as the urine retains the alkaline minerals that it needs – the right balance of calcium, magnesium, phosphate, sodium and potassium – the kidney ideally should be producing acidic urine to maintain that alkaline blood stream.

KG: So, when people are measuring there alkaline-acidity balance with an alkaline piece of paper and they are testing their urine, it’s not giving the right reading, is it?

RP: No, you want your blood to be alkaline and to do that your urine ideally, usually is on the acidic side and people with alkaline urine, tend to deposit minerals just because of the physics of the situation.

KG: I hope the audience understands this because it can be a little bit confusing. Say it again, would you, Dr. Peat?

RP: OK, the kidneys are very important along with the lungs in maintaining the alkaline normal condition of the blood stream. And to do that your lungs blow out the acidic CO2, and your kidneys according to the need, they can adjust the pH but the most stable situation is for the kidneys, like the lungs, to excrete a slightly acidic material.

"yerrag, post: Ray says that urine is has to be acidic, because the blood has to be basic, and that's because the cell has to be acidic:

I think this important. A common misunderstanding, is that acid urine will "sunburn" the tissues. In fact it's alkaline urine that burns things down below. How does a person correct this alkaline imbalance?

 

[yerrag]

Coming from my naturopath doctor, the ideal urine pH should be somewhere between 6.50-6.80, thereby slightly acidic.

I think this imbalance has a lot to do with having the enough CO2 in the blood, such that blood can release oxygen to the cells easily. In a healthy system, CO2 is readily produced with an efficient production of energy using respiratory oxidation, where CO2 is released as a by-product of the metabolism of sugar and oxygen to produce energy. For that to happen, there should be enough thyroid in the system to enable respiratory oxidation.

First thing to find out is the state of one's thyroid. There are blood tests for endocrine markers as well as other test such as the Achilles tendon reflex test and the QT interval in an ECG, among others.
