Food Factors That Affect Psoriasis

Psoriasis Triggers

Stress and certain medications, including beta blockers and NSAIDS (nonsteroidal anti-inflammatory drugs), can trigger psoriasis. Sunburns, scratches, and insect bites also tend to cause flare-ups. Could what you’re eating also play a role? Research has not yet proven a definitive link between your diet and psoriasis. However, many people find they experience flare-ups after enjoying certain foods, while certain foods seem to help ward off exacerbations.
