Scientists are still doing ongoing research on the link between certain foods/drinks to psoriasis flare-ups. However, some individuals have attested that avoiding the following food items have helped alleviate their symptoms:

Alcohol

Alcohol can worsen your psoriasis and here’s the reason why: when you drink alcohol, your blood vessels become dilated letting in more white blood cells into the skin. T cells are part of white blood cells and these cells are said to be a factor in the development of psoriasis. Therefore, when you drink alcohol, you let in more T cells into your skin, which can worsen your symptoms of psoriasis. That's why experts recommend people with psoriasis to avoid alcohol at all times in order to prevent psoriasis flare-ups.

Red meat

Red meat has a polyunsaturated fat called arachidonic acid that can worsen your symptoms of psoriasis because this kind of fat can be easily turned into inflammatory compounds, and any inflammatory compound can increase your chances of flaring up. If you have psoriasis, remember to avoid red meat and processed meats like bacon and sausage.

Junk food

Saturated fats, trans fats, refined sugars, and starch found in junk foods can cause inflammation which may then result to flare-ups for those with psoriasis.

Some people with psoriasis also have weight issues. This should be reason enough to avoid junk foods, as these snacks will not help them maintain a healthy weight. Having psoriasis also elevates the risk of developing heart disease. The addition of junk foods into one's habit, can do more harm than good to someone with this skin condition.

Dairy Products

Dairy products have arachidonic acid just like red meat, which can worsen psoriasis symptoms. It is also best to avoid dairy products especially cow’s milk in order to avoid flare-ups.

Pimiento and other condiments

Some reports show that people with psoriasis experience flare-ups after they’ve consumed condiments such as pimiento, curry, cinnamon, vinegar, paprika, Tabasco sauce and Worcestershire sauce. Some people even said that they flared up after ingesting mayonnaise so best to avoid these condiments.
