Researchers of a study searched various databases and reviewed studies published from 2017 to 2021, analyzing the role of supplements and diet in managing psoriasis. The review found that a low-calorie diet can be helpful for patients with psoriasis who are obese. A gluten-free diet was found to be beneficial for patients with psoriasis with celiac disease or gluten sensitivity. The Mediterranean diet showed positive benefits for both skin and overall health outcomes in patients with psoriasis. The ketogenic diet did not have sufficient evidence to be recommended for psoriasis management. It was advised to avoid the Western high fat, high sugar diet due to its potential to worsen inflammation.

Regarding supplements, the review found limited evidence to recommend most of them for treating psoriasis. Probiotics were suggested as a potential avenue for treatment, as they have shown the ability to modify the gut microbiome in various inflammatory skin diseases. However, the use of antibiotics for this purpose may have negative side effects.
