PH Balance - Acids and Alkalines

Updated on January 26, 2014

The Ph Factor

How often does your doctor talk to you about your PH balance?

Chances are never, and that's a shame because your body is always striving to maintain a balanced Ph level.

Most of the foods we eat today is acidic which contributes to many of the health issues people have to deal with.

What Does PH Mean?

The concept of pH was first introduced by Danish chemist S. P. L. Sørensen at the Carlsberg Laboratory in 1909.Sørensen. He suggested the notation "PH" for convenience, standing for "power of hydrogen". PH is the measure of the acidity or alkalinity in the body or of a solution.

The pH of different body fluids, including urine, saliva, and blood, varies with function and other factors. They are tightly regulated systems to keep the acid-base balanced. Acidic substance in the body creates plaque. Plaque's pH is low and will dissolve teeth if not removed.

The pH of blood, at a value of 7.4. pH, is vital in maintaining the functioning of cells. Enzymes are heavily affected by changes in pH, they have an optimum pH at which they operate. Outside a small range they can denature, the body cannot survive being either to acidic or alkaline for an extended period of time.

PH Scale

The pH scale ranges from 0 (the highest acidic) to 14 (the most alkaline).

A solution with a pH of 7 is neutral. When healthy, the blood pH is 7.365, the pH of spinal fluid is 7.4, and the saliva pH is 7.4. This ideal blood pH measurement means it is more alkaline than acid. At pH 7, water contains equal amounts of H+ and OH- ions. Substances with a pH of less than 7 are acidic because they contain a higher concentration of H+ ions. Substances with a pH higher than 7 are alkaline because they contain a higher concentration of OH-


In the United States diets are mainly acidic. Processed foods, sugars, and red meats all contribute to a low pH number. To survive, your body must maintain a pH number in the 7.2 range. Since most diets are acidic, your body is constantly looking for alkaline substances to maintain the 7.2 pH level.

Where Does Your Body Find Alkaline?

One of the biggest sources for alkaline is bone (calcium).

Your body can't produce alkaline so it must be ingested or your body will eat away at your bones to get it. Remember that your body will do anything necessary to survive, even extract alkaline from your bones.

Could this be why so many people have an osteoporosis problem? Ask your doctor and see what they say.

Other Contributors to Acidic pH Levels

We already know that a bad diet is the number one contributor to acidic pH levels, but there's another thing that creates acid, it's called "stress."

Stress (anxiety) plays havoc with your system. Stress is the cause of all sorts of physical ailments and in this case it's more of a chemical reaction. Stress also weakens your immune system.

Society in general seems to be constantly battling these elements of diet and stress, and in reality the only awareness that needs to take place is balancing your pH levels.

Foods - Acid or Alkaline

As mentioned, diet is a major factor in balancing your pH level.

It doesn't take a lot of changes to improve ones pH levels, in fact, there is something called the "alkaline diet" that is worth looking at.

Here are foods, some of which are included in the alkaline diet, and some which are just good to eat for a balanced diet.

The following foods are ranked from highly alkaline to highly acidic:

Highly Alkaline Forming Foods

Baking soda, sea salt, mineral water, pumpkin seed, lentils, seaweed, onion, taro root, sea vegetables, lotus root, sweet potato, lime, lemons, nectarine, persimmon, raspberry, watermelon, tangerine, and pineapple.

Moderately Alkaline Forming Foods

Apricots, spices, kambucha, unsulfured molasses, soy sauce, cashews, chestnuts, pepper, kohlrabi, parsnip, garlic, asparagus, kale, parsley, endive, arugula, mustard green, ginger root, broccoli, grapefruit, cantaloupe, honeydew, citrus, olive, dewberry, carrots, loganberry, and mango.

Low Alkaline Forming Foods

Most herbs, green tea, mu tea, rice syrup, apple cider vinegar, sake, quail eggs, primrose oil, sesame seed, cod liver oil, almonds, sprouts, potato, bell pepper, mushrooms, cauliflower, cabbage, rutabaga, ginseng, eggplant, pumpkin, collard green, pear, avocado, apples (sour), blackberry, cherry, peach, and papaya.

Very Low Alkaline Forming Foods

Ginger tea, umeboshi vinegar, ghee, duck eggs, oats, grain coffee, quinoa, japonica rice, wild rice, avocado oil, most seeds, coconut oil, olive oil, flax oil, brussel sprout, beet, chive, cilantro, celery, okra, cucumber, turnip greens, squashes, lettuces, orange, banana, blueberry, raisin, currant, grape, and strawberry.

Very Low Acid Forming Foods

Curry, koma coffee, honey, maple syrup, vinegar, cream, butter, goat/sheep cheese, chicken, gelatin, organs, venison, fish, wild duck, triticale, millet, kasha, amaranth, brown rice, pumpkin seed oil, grape seed oil, sunflower oil, pine nuts, canola oil, spinach, fava beans, black-eyed peas, string beans, wax beans, zucchini, chutney, rhubarb, coconut, guava, dry fruit, figs, and dates.

Low Acid Forming Foods

Vanilla, alcohol, black tea, balsamic vinegar, cow milk, aged cheese, soy cheese, goat milk, game meat, lamb, mutton, boar, elk, shellfish, mollusks, goose, turkey, buckwheat, wheat, spelt, teff, kamut, farina, semolina, white rice, almond oil, sesame oil, safflower oil, tapioca, seitan, tofu, pinto beans, white beans, navy beans, red beans, aduki beans, lima beans, chard, plum, prune and tomatoes.

Moderately Acid Forming Foods

Nutmeg, coffee, casein, milk protein, cottage cheese, soy milk, pork, veal, bear, mussels, squid, chicken, maize, barley groats, corn, rye, oat bran, pistachio seeds, chestnut oil, lard, pecans, palm kernel oil, green peas, peanuts, snow peas, other legumes, garbanzo beans, cranberry, and pomegranate.

Highly Acid Forming Foods

Tabletop sweeteners like (NutraSweet, Spoonful, Sweet 'N Low, Equal or Aspartame), pudding, jam, jelly, table salt (NaCl), beer, yeast, hops, malt, sugar, cocoa, white (acetic acid) vinegar, processed cheese, ice cream, beef, lobster, pheasant, barley, cottonseed oil, hazelnuts, walnuts, brazil nuts, fried foods, soybean, and soft drinks, especially the cola type. To neutralize a glass of cola with a pH of 2.5, it would take 32 glasses of alkaline water with a pH of 10.

Testing at Home

You can buy test strips for urine and saliva testing at your local pharmacy store. The more accurate test is a blood test.

You need to test yourself at different times of the day to get a well rounded view of where your pH is at. It won't be surprising to see your pH levels below 7.3.

Statistics show that more than 90 percent of the people in the United States are acidic. This is one reason so many people have health issues, and with a little education and work a lot of these issues could be eliminated - so sad.

      Novascotiamiss, water is neutral at about 7.2 on the PH scale. When chemicals are added to them (chlorine, etc) this changes the water composition. Filters can only do so much, I drink distilled water because distillation removes almost all impurities, this process also removes minerals that water provides. So, if you go distilled be sure to supplement your minerals. If you are so inclined you might check out devices that raise the alkaline value of water plus purify it, these machines are not cheap ($3000.00 and up), but over time can pay for themselves both in money and health benefits.

      Thanks, for some extremely useful information. My PH level seems to be out every now and then and this gives me a good idea. I will definitely do some more research. By the way I recently read that filtered water is acidic. We had to fit an arsenic filter to our drinking water and I therefore suspect that it may therefore become acidic. Do you know anything about this?

      Thanks for the comment, yes most bottled water is not much better than tap and your kidney will thank you for it later in life.

      Wow - this is great! We have an alkaline water filter in our kitchen now so we are certain of getting a higher alkaline-level water. We were getting "pure water" from a water store and when I tested it it was very acidic - it made us feel thirsty all the time. Good info rb - lots of stuff I didn't know.

      Yes this is truly useful. We all read about the Ph-Balance in school days but forget as we grow.
