Acid-Alkaline Diet
words by Helaina Lungu
About The Diet

Acidosis is a disturbance in the normal Acid/Alkaline balance of the body where the acidity of the body fluids and tissues is
abnormally high. It produces a low bodily pH. It occurs as a result of malfunctions of the body’s acid-base balancing mechanism.

Acidity or alkalinity can be measured using the pH scale: 0 – 7 is acid, 7 is neutral and 7 – 14 is alkaline. Most body fluids should be slightly alkaline (7.4), with the exception of urine, saliva, and vaginal fluids which should
be slightly acid (6 – 6.8).

At least 50% of the diet should be made up of alkaline-forming foods (and 50% of this raw). However, if you suffer from any of the above conditions, it is a good idea to try to eat 70 – 80% alkaline foods to alkalize the system. Acid foods tend to contain sulphur, phosphorus, chlorine, and iodine. Alkaline foods tend to contain more magnesium, sodium, potassium, iron, and calcium.

Foods are classified as acid or alkaline-forming, depending on the type of residue they break down into when digested. For example, lemons and ripe oranges, though tasting acid, actually is metabolised to an alkaline residue in the body.
Most fruits and vegetables are alkaline and most animal products and grains are acid-forming. When proteins are eaten, acids such as sulphuric and phosphoric acid are formed, and when carbohydrates and fats are eaten, acetic and lactic acids are formed.

Some foods are classed as neutral and if eaten together, can “neutralise” a more acid meal.
