Although some detox diets may claim to treat psoriasis, there is little scientific evidence to support these claims. Overly restrictive diets may also lead to nutritional deficiencies and associated health risks.

Detox diets for psoriasis may claim to reduce inflammation or remove toxins from the body to improve symptoms. However, more research is necessary to determine whether people can use diet to treat psoriasis symptoms.

Adding anti-inflammatory foods to a balanced diet may also be helpful for some people. A 2021 review suggests diets, such as the Mediterranean diet, may help improve chronic inflammation.
