Alkaline Diet – Benefits

  • By encouraging a greater intake of real foods and reducing processed items, the alkaline diet may improve health.
  • It does not, however, lower the pH levels in your body to aid in the battle against disease.
  • The foundation of the alkaline diet is the notion that you may enhance your health by swapping out acid-forming foods for alkaline ones.
  • This diet’s proponents even assert that it can aid in the prevention of deadly illnesses like cancer.

The alkaline diet: what is it?

  • The alkaline diet, sometimes referred to as the acid-alkaline or alkaline ash diet, asserts that consuming particular foods can change your body’s pH.
  • Metabolic waste is the “ash” residue left over after food is converted into energy, much like in a chemical reaction.
  • Ash that is acidic, neutral, or alkaline makes up this waste. This diet’s proponents contend that your body’s acidity is influenced by the ash’s acidity.
  • Acidic ash can expose you to dangers, but alkaline ash is supposed to shield you from disease. You might be able to “alkalize” your body and enhance your health by consuming more foods that are alkaline.

What foods are included in an alkaline diet?

  • Protein, phosphate, and sulfur are food ingredients that turn to acidic ash, whereas calcium, magnesium, and potassium are considered alkaline.
  • Some dietary groups are classified as neutral, alkaline, or acidic:
  • Dairy, eggs, cereals, meat, poultry, fish, and alcohol are acidic foods.
  • Nutritive: milk, sugars, carbohydrates, and natural fats
  • Fruits, nuts, legumes, and vegetables are alkaline.


Alkaline diet proponents contend that your body’s acidity or alkalinity can be directly impacted by the metabolic waste, or ash, that results from burning food.

Normal pH ranges for your body

A substance’s pH value indicates how acidic or alkaline it is.

The pH scale goes from 0 to 14:

  • Acidic: 0.0–6.9
  • 7.0 is neutral.
  • Basic or alkaline: 7.1–14.0
  • A lot of people who support the alkaline diet advise people to check the pH of their urine to make sure it is over 7 (alkaline) and not below 7 (acidic).
  • It’s crucial to remember that your body’s pH varies substantially. There is no predetermined amount; certain areas are alkaline, while others are acidic.
  • Because of the hydrochloric acid it contains, the pH of your stomach is between 1.5 and 2.0.Reliable Source is quite acidic. It takes this acidity to break down food.
  • Human blood, on the other hand, has a pH of 7.35 to 7.45, which is always somewhat alkaline.Reliable Source If treatment is not received, a blood pH drop outside of the usual range can be fatal.
  • This, however, only occurs in specific illness states, such as diabetic ketoacidosis, famine, or alcoholism.

Food has an impact on your urine’s pH but not your blood’s.

  • For you to stay healthy, the pH of your blood must stay constant, and your body can control this pH in a number of efficient methods.
  • The pH of your blood won’t often alter significantly after eating. Food can, however, affect your urine’s pH level, but with relatively erratic results.
  • One of the primary ways your body controls the pH of your blood is by excreting acids in your pee.
  • For instance, your urine will become more acidic after eating a huge steak because your body will be eliminating the metabolic waste.
  • Urine pH is therefore a poor indicator of general health and the pH of the body as a whole. In addition to your nutrition, other factors may also have an impact.

Foods that produce acid and osteoporosis

  • A decline in the amount of bone mineral content is the hallmark of the degenerative bone disease osteoporosis. It can significantly raise your risk of fractures and is especially prevalent in postmenopausal women.
  • According to the alkaline diet theory, your body uses alkaline minerals from bones to buffer acids from foods that cause your blood pH to rise. The “acid-ash hypothesis of osteoporosis” postulates that diets high in acid can lead to a decrease in bone mineral density.
  • But this notion doesn’t take into account how your lungs and kidneys work. Different acids, classified as “metabolic” (fixed) or “respiratory” (volatile), can be found in the blood.
  • Whereas volatile acids are expelled by the lungs, fixed acids are expelled in the urine. Carbonic acid is one type of volatile acid that is produced by the lungs during breathing. Your blood becomes more acidic as a result.
  • Meanwhile, bicarbonate—which is derived from the blood’s carbonic acid—is being reabsorbed by the kidneys. To keep you in the required pH range for life, this entire mechanism resists pH changes.
  • Additionally, the acid-ash theory ignores the part that collagen degradation plays in osteoporosis. Ironically, there is a substantial correlation between such collagen loss and low levels of orthosilicic acid and vitamin C in your diet.
  • Remember that there may not be a connection between dietary acid and bone health, according to new scientific research. In fact, because an acidic diet heavy in protein retains more calcium and activates the IGF-1 hormone, it may be associated with improved bone health.

Cancer and acidity

  • Comprehensive analyses of the connection between diet-induced acidosis, or elevated blood acidity brought on by diet, and cancer in the past found no evidence of a causal connection.
  • More recent studies indicate that food acidity and cancer may be related.
  • This study, however, does not account for blood acidity. Furthermore, it’s not apparent if dietary acid load is a direct cause of cancer. Indeed, studies have also grown cancer cells in an alkaline environment with success.
  • Moreover, tumors themselves produce acidity, even though they grow more quickly in these conditions. Cancer cells are the ones that produce the acidic environment—they are not the ones who cause the acidic environment.

Acidity and ancestral diets

  • There are differences when the acid-alkaline theory is examined from an evolutionary and scientific standpoint.
  • The main justification for the modern alkaline diet is from a research that found 87% of pre-agricultural individuals consumed alkaline diets.
  • Remember that our distant predecessors had access to a wide variety of foods and lived in climatically diverse environments. In actuality, as people moved farther north of the equator and away from the tropics, diets that formed acids became more prevalent.

Which ten foods are the most alkaline?

  • Fruit, nuts, legumes, and vegetables are the main types of alkaline foods. Ten instances consist of:
  • Apices
  • Broccoli with mushrooms
  • Peas, tomato, and apple
  • Cherries
  • Pineapple-flavored almonds
  • Seeds of pumpkins
  1. beets
  2. broccoli
  3. mushrooms
  4. peas
  5. tomato
  6. apple
  7. cherries
  8. pineapple
  9. almonds
  10. pumpkin seeds

How can you alkalize your body the quickest?

  • There is no foolproof proof that alkalizing your body is essential, nor is there a quick fix for it.
  • The pH levels in your body are strictly regulated, and food has minimal effect on blood pH. Urine pH might be affected in some way.


  • The alkaline diet’s emphasis on complete, unprocessed foods makes it healthy. However, credible research does not back up claims that it improves health by changing pH levels.
  • If you have chronic renal disease, a low-protein version might help, but there’s no proof that it affects pH levels.
