Nutrition in psoriasis

How to treat psoriasis? How to get rid of psoriasis naturally?

Proper nutrition seems to be crucial in the prevention and treatment of psoriasis.

Nutritionists’ opinion is that the ingestion of food containing toxins or the oxidation of the body itself are responsible for an organic imbalance that is manifested, in addition to some general body health problems, through unhealthy skin.

The use of a natural diet, very rich in foods with antioxidant properties, is capable of neutralizing these toxins. Moreover, the moderate use of certain foods prevents the occurrence of an intestinal imbalance that will worsen or trigger the onset of this disease.
