Acid-alkaline balance

Acid-alkaline balance – briefly

This idea refers to the books and methods of Dr. Stephen Domenig MD, “The Alkaline Cure“, and Dr. Eva-Maria Kraske MD, “The Acid-Alkaline Balance“. Dr. Kraske’s book is available in German, French, and Spanish, but not in English. An acid-alkaline balance is not a new idea, although the connection to food is controversial. Dr. William Howard Hay also wrote about an acid-alkaline balance in his book, “A New Health Era“, published in 1935. If you are looking for fast practical advice only, read this section only. If you are looking for an explanation and the scientific details, read the rest of this article. These doctors write that:

  • Some foods are acid-forming in the body, reducing the pH of the blood, tissues, and organs very slightly, depending mostly on the protein, phosphorous, chloride, or refined sugar content of the food.
  • Some foods are alkaline-forming, increasing the pH of the blood, tissues, and organs very slightly, depending mostly on the mineral content of the food, such as magnesium, potassium, calcium, and sodium.
  • Healthy digestion depends on eating sixty to ninety percent alkaline-forming foods and ten to forty percent acid-forming foods, measured by portions, depending on the specific person and biochemical individuality. Dr. Domenig recommends a mix of two to one (2:1) of alkaline-forming foods to acid-forming foods. Again, the optimal proportion is variable.

For example, lemons have a sour, acidic taste, but due to their mineral content they are alkaline-forming after they pass through your stomach. Again, the factors that make a specific food acid-forming are the refined sugar, starch, or protein content. Most starch, even so-called “slow carbohydrate”, such as wheat bread and pasta, is similar to refined sugar, causing a slight acidification of the body. Most fruits and vegetables are alkaline-forming.

The goal is to improve digestion, which naturally results in a healthy weight and longevity. Good health depends on optimal digestion. What is optimal digestion? It begins with an absence of constipation, bloating, diarrhea, stomach pains, and excess gas. It continues with absorption and assimilation of the nutrients into your blood, tissues, and bones. Good digestion ends with healthy excretion and leads to a healthy weight and healthy ageing.

 

Table – acid-forming and alkaline-forming

The following table lists the most common acid-forming and alkaline-forming foods:

Acid-forming Alkaline-forming
eggs, fish, turkey, beef, lamb, chicken  vegetables, especially broccoli, spinach, kale, parsley, red beets, carrots, garlic, ginger, onion, sweet potato,  coriander, endive, celery, cucumber, cabbage, sweet pepper (paprika), sprouts, avocado, asparagus, seaweed, algae
walnuts, pecans, most oils, nuts, and seeds (except almonds, hemp seeds, chia seeds, and some pumpkin seeds) many but not all fruits, especially lemons, other citrus (except orange), pomegranate, coconut, rhubarb, tomato
wheat, including “whole wheat”, bread, pasta, oats, other grains and cereals, except brown rice, buckwheat, millet, quinoa, amaranth (alkaline or less acidic) almonds, hemp seeds, chia seeds, some pumpkin seeds, olive oil, and flaxseed oil
most beans, except adzuki beans cayenne, turmeric, cinnamon, dandelion, ginger, clove
coffee, black tea, alcohol, cocoa, chocolate, honey, pickles, ketchup, fried foods, salt most herbs and spices, green tea, bee pollen
refined sugar, even brown sugar adzuki beans, tofu (fermented food), umeboshi plums
dairy, milk, cheese, yogurt (cow’s dairy) blackstrap molasses, sea salt, mountain salt
food additives (preservatives, colorings, flavoring, emulsifiers, others) apple cider vinegar (fermented food)
pharmaceuticals (antibiotics, psychotropics, antihistamines, aspirin, …) oxygen

Note that different authors reach different conclusions about whether a specific food is alkaline-forming, but they all agree on the basic outline. Perhaps one specific batch of the same food can be alkaline-forming, depending on its mineral or vitamin content, while another batch of the same food can be acid-forming, depending on how it was grown, the pH of the soil, and so on. I do not know how to resolve these contradictions, but again, they agree on the outline in the preceding table.

You could try it for a week, if you eat at least two or three alkaline-forming portions, such as fruits or vegetables, at every meal with at most one acid-forming food, such as starch or protein. You could then observe your own digestion and then see how you feel. You have nothing to lose. It can even be cheap, if you plan your meals, shop around, and cook for yourself.

For example, it is possible to start each meal with a green smoothie, hot soup, or lemon water. According to food combining, you then wait ten to fifteen minutes. Then eat steamed vegetables, such as broccoli, spinach, carrots, or your favorite raw vegetable. Lastly, eat eggs, fish, meat, possibly sauteed with onions and mushrooms. This sequence (liquid, vegetables, then eggs, fish or meat) is according to food combining. The idea of an acid-alkaline balance does not contradict food combining. Dr. Hay wrote about both. 

Hay suggested buying good-quality animal foods, such as grass-fed, pasture-raised chicken and eggs. If possible, it is better to exclude meat from confined animal farming operations. Try to know your suppliers, particularly local suppliers.

If you are vegan, then you might first take a green smoothie; hot soup, or lemon water. Then eat the vegetables. Only at the end of your meal do you eat your tofu, lentils, beans, brown rice, or healthy grains. If you enjoy nuts, then eat a few at the very end of the meal. Again, it can even be cheap, if you plan your meals, shop around, and cook for yourself.

Why does this work?

omeletDr. Domenig writes, “Too much acidity makes us age quicker. Worse, excess acidity creates an environment in the body where allergies and diseases can flourish.” A proper acid-alkaline balance can increase your “base metabolic rate”, which is the production of energy (adenosine triphosphate) at rest. This can give you a sense of more energy or at least less fatigue.

The calorie theory of weight gain and loss is a myth. Metabolism is the total of all processes and functions of the body to keep itself healthy and in balance. This includes digesting food, absorbing nutrients, repairing and renewing tissues and cells, producing hormones, and excreting waste. A renegade pharmacist further explains why this method works here.

What is acidity? What is “pH”?

Acidity and alkalinity are measured by pH. “pH” is an acronym for “potential hydrogen” (H+). pH is a measure of acidity or alkalinity. The pH scale is from zero (most acidic) to fourteen (most alkaline). Seven is neutral. Your stomach has a pH of nine-tenths to five (very acidic). Your urine is usually slightly acidic and reflects the acidity or alkalinity of your body. To observe this method work for you, buy pH test strips at your local pharmacy and measure the pH of your urine in the morning.

By definition, the more acid a solution (a liquid, such as blood or urine), the greater the concentration of hydrogen ions (H+). The more alkaline a solution, the greater the concentration of hydroxyl ions (OH-). In other words, the more alkaline a solution, the more oxygen it has. Your stomach, your urine, and your skin are acidic, but the rest of your body is slightly alkaline. On the other hand, you can be too alkaline. Some acid-forming foods are usually required to absorb the minerals of alkaline-forming foods into your blood. A balance is desirable, but the optimal balance depends on the person and also on their condition, according to biochemical individuality.

Regulating your pH autonomically

Your blood has a pH that varies between seven and thirty-five one-hundredths (slightly alkaline) and seven and forty-five one-hundredths. Without your consciousness, your nervous system tightly regulates your blood pH in this range. You do this mostly through your urine and your breath. This is why you breathe heavily after exercise. The carbon dioxide that you exhale is acidic. You can also gradually buffer your blood pH through your bones. If your blood tends to be slightly acidic over time, then you transfer alkaline-forming minerals from your bones to increase the pH of your blood and tissues. If your blood tends to be more alkaline over time, you deposit minerals in the blood into your tissues and then into your bones.

 

 

 

 

A truly “balanced diet”

Again, what you eat or do not eat can affect your urine pH.  This may also slightly affect your blood pH. Specific foods can be acid-forming or alkaline-forming after digestion, independently of their taste. Again, lemons have a sour, acidic taste, but are alkaline-forming after digestion. You can measure this effect on your urine, using pH test strips that you can find at your local pharmacy or online.

Try it for a week, and see how you feel. You have nothing to lose. It can even be cheap, if you plan your meals, shop around, and cook for yourself.

To reach your optimal acid-alkaline balance:

  • Eat mostly alkaline-forming foods – sixty to ninety percent, such as two to four portions per meal,
  • Eat some acid-forming foods – ten to forty percent, such as one portion per meal,
  • Keep proper food combining in mind. Possibly cut sugar, dairy, and wheat.

According to Dr. Susan Richards MD, author of “Acid Alkaline Balance: The Missing Link to Health“, the elements that form acidic residue in the body are chlorine, phosphorous, sulfur, and iodine. The minerals that leave alkaline residues, similar to the ash of burned wood, are potassium, magnesium, calcium, and sodium.

Since health depends on a balance, it is desirable to include some acid-forming foods in your eating habits, such as small portions of salt, walnuts, eggs, turkey, beef, or chocolate. Most but not all nuts, grains, beans, and legumes are acid-forming.

Refined salt is made of sodium and chlorine. It tends to be acid-forming. Sea salt and mountain salt have other minerals, such as iodine, selenium, and trace minerals, which can make them either acid- or alkaline-forming on balance. Fibrous vegetables, buckwheat, oats, millet, and quinoa contain phosphorous. The phosphorous is acid-forming, but other minerals, such as magnesium, potassium, and calcium, can make these foods alkaline-forming on balance.

Similarly, onions and garlic contain sulfur, an acid-forming element, but other minerals can make these foods alkaline-forming on balance. Sardines, kelp, and small fish from the sea contain iodine. See the above table for details.

CriticsSciientific discussion

Skeptics and critics of the concept of the acid-alkaline balance point out that you have no direct, conscious control of your blood pH. It is controlled by your autonomic (parasympathetic) nervous system without your consciousness.

Only your liver, kidneys, and lungs regulate your blood pH, without your thinking about it, at least according to this point of view. To offset acidity and restore a pH balance, your kidney actively and passively pulls bicarbonate from your gastro-intestinal tract. If there is little bicarbonate to pull, then is it possible that this can cause an imbalance? Your lungs exhale carbon dioxide, which is acidic.

What is the cause of too much acidity in the blood? Why not modify eating habits first? What if your liver, kidneys, or lungs are weak, damaged, depleted, or insufficient? Is there a possible long-term buffering – via the minerals in your tissues and bones?

None of the critics appear to have read these books nor tried this method for themselves. Some of the critics misinterpret the idea of an acid-alkaline balance, claiming incorrectly what is to be included and what is to be excluded. This does not prevent you from reading what the critics write, but thinking for yourself. First think. Then talk. Then act. Try it for a week, at all meals, and see how you feel. If you eat a lot of snacks between meals, then eat mostly alkaline-forming snacks, such as fruits or vegetables and then almonds or pumpkin seeds.

In this thirty-nine-minute, subtitled video, Barbara O’Neill clearly describes the acid-alkaline balance. Other references are Dr. Russell Jaffe, Dr. Elson Haas, Dr. Otto Warburg, and others.

Acid-alkaline balance – an art and not a precise science

Many books have been written about an acid-alkaline balance. Different authors interpret this idea differently. Some of them contradict each other about whether a specific food is acid-forming or alkaline-forming. This can be confusing, but they agree on the guidelines and on a desirable balance.

For optimal digestion and health, it is desirable to eat mostly alkaline-forming foods. What foods are alkaline-forming? In general, most vegetables and fruits and some nuts (almonds) are alkaline-forming for everybody. What foods are acid-forming? In general, coffee, sugar, starch, processed foods, wheat, pasteurized cow’s dairy, eggs, fish, meat, and most nuts are acid-forming for everybody.

Because of biochemical individuality and the diversity of other specific foods, it is possible that some foods may be acid-forming for some people but alkaline-forming for other people. Why? It may be for reasons that nobody understands, possibly because of the mineral content and the specific batch of that specific food and the specific person. Listen to your body. Try it for a week, eating according to your acid-alkaline balance, with two or more alkaline-forming foods at each meal followed by at most one acid-forming food, such as protein or starch. Eat as much as you want. Listen to your body, and see how you feel.

For me, the references are Dr. Domenig, Dr. Kraske, Dr. Richards and this list of acid- and alkaline-forming foods. Dr. Kraske points out that this idea is not new. She refers to Dr. Franz Xaver Mayr in 1900, the nutritional researcher Ragnar Berg, and Dr. Maxmillian Bircher-Brenner. All of them were active in the beginning of the twentieth century. Naturally, each of them had their own ideas and recipes, but they all promoted the idea of the acid-alkaline balance. 

The idea of the acid-alkaline balance transcends the idea “to eat more fruits and vegetables”. The type of soil the fruits and vegetables were grown in determines the mineral content. The roots, stalks, and leaves pull the minerals from the soil. The beauty of the idea of the acid-alkaline balance is that it also transcends the vegan-carnivore controversy. Note that there are no clinical studies to confirm the acid-alkaline balance, but there are also no clinical studies to prove that water is a cure for dehydration nor that prunes have a laxative effect.

Related to the acid-alkaline balance is the idea that the body is electric. pH means voltage in liquids, according to Dr. Jerry Tennant MD. The optimal alkalinity of blood, 7.35 – 7.45, is equivalent to a certain number of millivolts. Dr. Tennant healed himself of chronic illness, using energy medicine and addressing the related root causes to prompt his body to produce more new cells. He claims that chronic illness results from low energy and that regeneration of new cells requires a certain level of millivolts. An opthamologist, he claims that he used this technique to heal people of macular degeneration. He describes his ideas and experience in this interview with Dr. Mercola.
