Psoriasis is an autoimmune disease that affects the skin.

While there are many different factors that can trigger a flare-up of psoriasis symptoms, including stress and injury to the skin, there are also certain foods that are known to cause inflammation in the body, which can exacerbate psoriasis symptoms. If you have psoriasis, it’s important to be aware of these foods and to limit your intake of them in order to minimize the likelihood of a flare-up. Here are 7 of the most common foods that trigger psoriasis flare-ups:.

1. Red Meat

Red meat is high in saturated fat, which has been linked to inflammation in the body. Additionally, red meat is often processed with chemicals that can cause inflammation in some people.

For these reasons, it’s best for people with psoriasis to limit their intake of red meat.

2. Dairy Products

Dairy products, especially those that are high in fat, can be problematic for people with psoriasis.

Dairy is often processed with hormones that can trigger inflammation in the body, and it’s also common for people with psoriasis to have a dairy intolerance, which can exacerbate their symptoms. If you have psoriasis, it’s a good idea to limit your intake of dairy products and to look for alternatives, such as plant-based milks and cheeses.

3. Nightshade Vegetables

Nightshade vegetables, including tomatoes, peppers, potatoes, and eggplant, contain a type of alkaloid that can trigger inflammation in some people.

While these vegetables are generally considered healthy, they can be problematic for people with psoriasis. If you have psoriasis, consider limiting your intake of nightshade vegetables and monitoring your symptoms to see if there is any improvement.

4. Gluten

Gluten is a protein found in many grains, including wheat, barley, and rye. Some people with psoriasis may be sensitive to gluten, and consuming it can trigger inflammation in the body.

If you have psoriasis, it may be worth trying a gluten-free diet to see if it helps to improve your symptoms.

5. Processed Foods

Processed foods, such as packaged snacks, cereals, and frozen dinners, are often high in sugar, salt, and unhealthy fats. These ingredients can contribute to inflammation in the body and can trigger a psoriasis flare-up.

If you have psoriasis, it’s best to avoid processed foods as much as possible and to focus on whole, unprocessed foods instead.

6. Alcohol

Alcohol is a common trigger for psoriasis flare-ups. Alcohol can cause dehydration, which can make psoriasis symptoms worse, and it can also compromise the immune system, making it more difficult for the body to fight off psoriasis.

If you have psoriasis, it’s important to limit your alcohol intake and to stay hydrated by drinking plenty of water.

7. Sugar

Sugar is known to cause inflammation in the body, and it can be particularly problematic for people with psoriasis.

Sugar is found in many processed foods, including baked goods, candy, and soda, so it’s important to read labels carefully and to limit your intake of sugary foods and drinks.

While these foods can trigger psoriasis flare-ups in some people, it’s important to note that everyone is different.

What works for one person may not work for another, so it’s important to pay attention to your own body and to identify which foods trigger your psoriasis symptoms. If you have psoriasis, it can be helpful to work with a healthcare professional or a registered dietitian to develop a diet plan that is tailored to your specific needs.
