The acidic foods have a inflammatory effect on the body. They are therefore to be avoided or limited in all diseases linked to inflammation. Thus, the fruits (especially citrus fruits), some vegetables (spinach, tomatoes, cauliflower, artichoke, onion, mushrooms), condiments and yoghurt will be prohibited.

The acidifying foods, which do not have an acidic taste but generate acids during digestion should also be avoided. This is the case of animal and vegetable proteins (legumes), refined sugars and White flour.
