Acidosis: how the body turns sour and why your joints ache because of it

Dr. Boris Wydoff · 2026-09-10

There is a condition you will not find on any lab form, yet I see it in most people with chronic complaints. I am talking about acidosis — the souring of the internal environment by harmful acids. The body turns sour over years, and for years it pays the price in fatigue, inflammation and aches that get treated one by one, without anyone seeing the common root.

WHERE ACID WASTE COMES FROM
The main suppliers are too much sugar and white flour, too much meat, and processed food. As they are digested, they leave acid residues behind. While there are few of them, the body copes: it neutralises them and carries them out. But when there is more acid than the kidneys and lungs can remove, the body starts to defend itself — and it does so at your expense.

What the body pays with

To quench the acid, the body takes alkaline minerals out of its own reserves — calcium first of all. Hence a chain that people rarely connect: souring → minerals washed out → weakening bones, teeth, nails. An acid environment is a friend of inflammation: the joints answer with pain "for no reason", the skin with rashes, and the person as a whole with a tiredness that rest does not cure.

How to test it on yourself

Three weeks without the big three — sugar, white flour, processed food — with vegetables at every meal and enough water. Your joints, your skin and your morning freshness will answer more honestly than any argument. Many people remember for the first time in years that you can wake up feeling light.

What makes you alkaline

  • Vegetables and greens are the foundation: the more living food on the plate, the calmer the inner environment.
  • Fresh vegetable juices — the quick alkalising tool of my system.
  • Lemon — despite its sour taste, in the body's chemistry it works as an alkali.
  • Water when you are thirsty: the kidneys need something to flush the acid residues out with.
  • Breathing: a full exhale is also acid leaving — carbonic acid.

A word of caution

Acidosis as I understand it is a condition of diet and way of life. Acute disturbances of the acid-base balance in diabetes and kidney disease are a medical situation: there it is the doctor who decides, not the diet.

Frequently asked questions

What is acidosis in simple words?

It is a build-up of acid waste from metabolism, when the body cannot carry it out fast enough. The sources are sugar, white flour, too much meat and processed food.

How is acidosis linked to joint pain?

An acid environment keeps inflammation going, and to quench the acid the body spends its own minerals. The joints answer with pain "for no reason" — pain that often quietens down after three weeks of clean eating.

Which foods alkalise the body?

Vegetables, greens, fresh vegetable juices, lemon. Plus water when you are thirsty and full breathing — acid leaves through the kidneys and through the lungs alike.
