The holidays are a time to eat, drink, and be merry. But if you have psoriasis, you may be watching what you eat and drink closely. Not all foods affect people with psoriasis the same way, but there are a few that are notorious for their tendency to trigger psoriasis flares. To prevent inflammation and reactions to foods you’re sensitive to, consider limiting or avoiding any foods that have triggered your psoriasis in the past. This may include any of the following seven common offenders.

1. Red and Processed Meat

Research into the relationship between red and processed meats and psoriasis remains inconclusive, but studies do suggest that these meats can raise inflammation levels in the bloodstream. Because psoriasis flare-ups can result from an increase inflammation, you might want to skip the bacon-wrapped scallops and limit the holiday ham.

“Psoriasis is a condition where your immune system gets angry at your skin and attacks it, leading to inflammation,” says Joshua Ziechner, M.D., a board-certified dermatologist in New York City. “Anything that promotes inflammation, theoretically, can be an aggravating factor.”
