Acid & Alkaline Nutrition: Shattering the Myths

By Michael McEvoy, FDN, CNC, CMTA

Acid and alkaline imbalances always involve respiratory function. The respiratory and renal involvement in acidosis or alkalosis may be either part of the cause of or part of the compensation for the acidosis or alkalosis. The most dangerous misconception among nutritionists concerned with pH balance, one seems to reign supreme in the minds of an appalling majority of doctors, is that ACIDOSIS is ubiquitous among the sick of this world.

Acidosis, they have been given to believe, is an accompaniment to, and even the primary cause of, every disease, every pain, every state of ill health to afflict humankind.”Wouldn’t it be nice if it were that simple? Pump up your patients’ alkaline reserves and cure them of anything?” And an ALKALOSIS? No such thing?

Acid is bad, this theory contends, and alkaline is good. And there is no way one can have too much of a good thing. In truth excess alkalinity is just as harmful as excess acidity. All physiological systems are maintained through a negative feedback mechanism that operates in a dualistic manner.

Dualistic means that for every reasonable condition, there are two(2) abnormals – abnormally high and abnormally low. To say that there is only one abnormal concerning pH balance is to display total ignorance of the most fundamentals of physiology.

An Analytical System of Clinical Nutrition

In metabolic alkalosis, there are increasing levels of bicarbonate ion concerning H+. There are three leading causes of bicarbonate increase: Direct administration or production of alkaline-sodium bicarbonate, or other antacids, can lead to metabolic acidosis. Excess bicarbonate is absorbed as the Co2 levels begin to rise.”Acid-Losing Alkalosis – The loss of H+ from stomach from chronic vomiting or pyloric stenosis is a significant cause of acid-losing alkalosis.

Potassium Deficient Alkalosis – This is most often caused by an excessive loss of potassium from the kidney. Intracellular potassium will move out of the cells to replace the potassium being lost in the plasma and urine. Sodium and H+ move into the cell to replace the potassium that has run out.

This leaves a deficit of H+ in the plasma. Also, H+ is secreted by the kidneys along with potassium. The net result of renal excretion and extracellular H+ loss is an increased production of H+ to replace that which has been lost. This results in a concomitant rise in bicarbonate or Co2 levels.”

Myth #1: It is GOOD to be alkaline, it is BAD to be Acidic

Truth: It is BAD to be Alkaline, it is BAD to be Acidic. Most people, including uninformed doctors, naturopaths, and alternative health people throw around terms like acid and alkaline but have very little understanding of what they are talking about. It is a fact that acidosis is pathological, and can wreak havoc on the body. What is not known as widely in the health world, is that alkalosis

Is ALSO pathological and will cause just as many, if not more problems with your health. The majority of people that I see in my practice are TOO ALKALINE. Some common symptomatology associated with Alkalosis:

Hypothyroidism
Hypochlorhydria (low stomach acid, HCL)
Allergies
Wheezing
Diarrhea
Fatigue

Feel more like the ‘tortoise,’ less like the ‘hare.’

Myth #2: Most people are too acidic

Truth: Most people tend to be too alkaline. I would estimate that 70% of the people I see suffer from alkalosis symptoms. Many people are in a para-sympathetic imbalance or a slow-oxidative imbalance. This tends to push their blood pH levels to the high side. Causes of metabolic alkalosis include loss of acids (H2Co3), excess consumption of bicarbonate, chloride depletion, Adrenal Aldosterone excess, Potassium Depletion causing an increased exchange of H+ for NA+ in the kidneys, allowing H+ to be secreted, and bicarbonate to be retained.

Myth #3: Meat is Acid Forming

Truth: Your pre-existing metabolism determines how food and nutrient will behave in your body, the pH of food does not. For many people, meat has an alkaline effect on blood pH! To understand this, you must realize that each person is biochemically unique. Food and nutrients will behave very differently in people because biochemistry is individual. Certain individuals have a metabolism that is designed to assimilate protein and fat more efficiently than plant foods. Other people have a metabolism that is intended to utilize plant foods more efficiently while having less of a need for protein and fat. These facts of metabolic individuality are fundamental to the understanding of how nutrients will behave in your body.

Myth #4: Vegetables are Alkalinizing

Truth: Plant Foods will produce either an alkaline or an acidifying effect on the cells of your body. But that is determined by your pre-existing metabolism, not by the food itself. The ONLY metabolic types that will have an alkaline response to vegetables are “Autonomic Dominants”: Para- Sympathetic Dominant Protein Types, and Sympathetic Dominant Carbohydrate Types. Vegetables will produce an “acidifying effect on “Oxidative Dominants” (Slow-Oxidizing Carbohydrate Types and Fast Oxidizing Protein Types). Potassium is acidly forming within oxidative metabolism and alkaline forming for those with Autonomic dominance.

Myth #5: The most accurate measurement of a person’s pH is through urine and saliva pH

Truth: While litmus paper can be used to identify pH imbalances, the most accurate analysis of a person’s pH is through the Venous Plasma pH. Venous blood has returned from the sites of significant metabolic activity and has in it the discharged waste after nutrients are assimilated in arterial blood. Other useful indicators of acidosis and alkalosis are:

On a blood test if CO2 is low (<24) and chloride is high (>106), a person may have Metabolic Acidosis.
On a blood test if CO2 is high (>27) and chloride is low (<100), a person may have Metabolic Alkalosis.
Breath Holding Time/Carbon Dioxide Challenge. The higher the breath hold time (65 seconds+), the more tending towards alkalosis on all levels. The shorter the breath holding time (40 seconds), the more tending towards acidosis on all levels.
Respiration Rate. A high respiration rate (19+ beats per minute) indicates acidosis tendencies. A lower respiration rate (13 beats per minute) means alkaline imbalance tendencies.

Myth #6: High Saliva or urine pH (6.8+) indicates that a person is Alkaline

Truth: If a person has high saliva or urine pH, this usually shows ACIDOSIS, but can also be a sign of respiratory alkalosis:
Metabolic Acidosis
Potassium Excess Acidosis
Respiratory Acidosis
Respiratory Alkalosis

Myth #7: The standard blood pH is between 7.35-7.45

Truth: As usual, the medical world gets it wrong. Upon careful study of venous plasma pH for decades, studied on thousands of patients, George Watson, Ph.D., and Rudolf Wiley, Ph.D. got it right! Their established median venous blood pH is 7.46. A 0.01 movement is an enormous shift in blood pH. A change from 7.46 to 7.48 is a massive shift towards pathological alkalosis. A difference from 7.46 to 7.43 is a tremendous shift towards pathological acidosis. These discoveries are titanic and have never received the recognition that they deserve. Read more about these nutrition pioneers in the books: ‘Nutrition and Your Mind’ (Watson) and ‘Biobalance’ (Wiley).

Myth #8: Blood Co2 levels between 20-30 are normal

Truth: Co2 on your standard blood test is a measurement of bicarbonate, which is alkaline. The standard laboratory reference ranges for many blood chemistry factors, including Co2 are ridiculous. The reference range I use I believe is much tighter and more accurate: 24-27. Lower than 24 indicates acidosis, higher than 27 points alkalosis. Reality there are numerous kinds of acid/alkaline balances in the body:

Respiratory alkalosis
Potassium depletion alkalosis
Metabolic alkalosis
Metabolic acidosis
Potassium excess acidosis
Respiratory acidosis

Your blood pH is reflected in your personality, or as I like to say your behavior range.

Acidosis

When in a state of metabolic acidosis, the enzyme systems of the body are running at high speed. This pushes the sympathetic nerves of the body and forces the adrenal glands into overdrive. In this state a person will:

Have Agitation
Feel Nervousness
Have Anxiety
Feel more like the ‘hare,’ less like the ‘tortoise.’
Feel physically tired but mentally wired
Compensate by tending to take deeper inhalations
Have a low tolerance for carbon dioxide and can hold breath for less than 45 seconds in metabolic acidosis Alkalosis. When in a state of metabolic alkalosis, the enzyme systems of the body are running sub-par. This pushes down pulse, and blood pressure inhibits sympathetic activity and can contribute to low thyroid activity.

In this state a person will:
Have a difficult time getting out of bed in the morning
Feel more like the ‘tortoise,’ less like the ‘hare.’
Feel sluggish
Feel burned out and tired
Have a much higher tolerance for carbon dioxide, and should be able to hold breath for 60 seconds or more.

In metabolic alkalosis, and in potassium depletion alkalosis the saliva pH will be less than 6.6, and the urine pH will be higher than 6.3. In respiratory alkalosis, the saliva pH will tend to be higher than 6.8. How to Effect pH Levels. Eat the foods that are most compatible with your type of metabolism. If you are a para-sympathetic protein type, your blood tends to be too alkaline. Adenine and purine- containing nucleoproteins are essential at every meal. These types of proteins will create the necessary acidic pH shift towards the median, 7.46. If you are a fast-oxidizing protein type, your blood tends to be too acidic. You also need higher purine foods like the para-sympathetic types, but these foods produce the necessary alkaline effect on your blood, bringing it back to 7.46. If you are a sensitive carb type, your blood tends towards acidosis. Your metabolism needs lots of vegetables and VERY LITTLE nucleo-proteins. Eating this way will create the necessary alkaline shift towards 7.46. If you are a slow-oxidizing carb type, your blood tends towards being too alkaline. Unlike the para-sympathetic-protein type, you need more vegetables and fewer purines. This will create the necessary Acidic shift in your blood pH, bringing it back to 7.46. If you have ever wondered why ‘one person’s food is another person’s poison,’ this article should shed some light on that.
