Psoriasis Diet & Nutrition: Foods, Supplements & What to Avoid

Diet doesn't cause psoriasis — but it has a real, documented effect on how severe your symptoms are and how well your treatments work. This section covers what the research actually shows: which foods help reduce inflammation, which reliably trigger flares, and which nutrients have the strongest evidence.

Diet at a glance — what helps vs. what triggers

Fatty fish — High omega-3 content reduces systemic inflammation. Salmon, mackerel, sardines 2–3× per week.

Alcohol — One of the most consistently documented dietary triggers. Also reduces treatment effectiveness.

Leafy greens & berries — Rich in antioxidants that lower oxidative stress in the skin and systemically.

Processed & refined foods — High glycemic load drives insulin spikes that increase inflammatory cytokines.

Vitamin D — Deficiency is common in people with psoriasis. Both diet and safe sun exposure help maintain adequate levels.

Red & processed meat — Associated with higher levels of arachidonic acid, a pro-inflammatory compound.
