Premise

The calculator on this page represents an important aid in evaluating the acid/base balance of various meals or of the diet as a whole. It is based on the PRAL ( Potential Renal Acid Load ) values ​​of individual foods and food products , published on the website www.acidosi.it.

We remind the reader that negative values ​​indicate an alkalizing potential of the food , while a positive PRAL indicates an acidifying effect .

  • Acidifying foods: include cheeses , meats, eggs, cured meats , chlorine , coffee , tea, simple sugars , refined flours , and cola-based drinks
  • Alkalizing foods : fresh fruit and vegetables . Calcium , potassium , sodium , magnesium .
  • Neutral/Slightly acidifying foods: whole grains , legumes , milk and dried fruit

A diet too rich in acidifying waste and poor in alkalising foods is associated with an increase in urinary calcium excretion, which represents a potential risk factor for the onset of osteoporosis. Furthermore, a diet of this type could be associated with a reduced metabolic efficiency of the organism, leading to recurrent infections, nervousness, fatigue , insomnia .

However, it should be noted that official medical science considers many of the positive effects attributed to alkalizing diets to have no scientific basis.

  • In therapy, alkalizing diets are used to prevent the appearance of certain types of urinary stones, such as uric acid and cystine stones. However, they are contraindicated in subjects exposed to the risk of phosphocalcic kidney stones (therefore in the presence of kidney stones , an alkaline or acidifying diet may be useful depending on the composition of the stones, consult your doctor!)
  • They could have a positive effect in the prevention of osteoporosis by reducing renal calcium excretion (even if high-protein , therefore acidifying, diets do not appear to increase the risk of osteoporosis , compensating for hypercalciuria with an increase in intestinal calcium absorption and synthesis of trophic hormones for bone)
  • They are contraindicated in alkalosis and acidosis linked to respiratory diseases
  • The medical-sports rationale for the use of supplements based on Alkalizing Agents (e.g. sodium bicarbonate , potassium bicarbonate , citric acid , potassium citrate …) is based on the process of partial neutralization of blood lactic acid , which it accumulates during very intense effortsforcing the athlete to reduce their performance level.

Calculate the pH of your diet

INSTRUCTIONS: select the foods that make up the diet from the drop-down menus and specify the relative quantities consumed (expressed in grams) in the column alongside. To speed up the search for foods, once you have selected the drop-down menu, use the keyboard to type the initials of the food you are looking for (for example, type pasta if you are looking for this food).
