Highly Processed Foods
Highly processed foods, such as fast food, sugary snacks, and frozen meals, can contain high levels of unhealthy fats, sugars, and additives. These ingredients can contribute to inflammation in the body, which may worsen symptoms of psoriatic arthritis. Avoiding highly processed foods and opting for whole, nutrient-dense foods can help reduce inflammation and support overall health.
Refined Carbohydrates
Foods high in refined carbohydrates, such as white bread, pasta, and pastries, can cause spikes in blood sugar levels. These spikes can lead to increased inflammation and may exacerbate joint pain and swelling in individuals with psoriatic arthritis. Choosing whole grains and complex carbohydrates can provide sustained energy levels and support better blood sugar control.
Red Meat and Dairy
Red meat and dairy products contain saturated fats that have been linked to inflammation in the body. Individuals with psoriatic arthritis may find that consuming red meat and dairy worsens their symptoms. Replacing red meat with lean protein sources, such as fish, poultry, and plant-based alternatives, can help reduce inflammation and support joint health.
Nightshade Vegetables
Some people with psoriatic arthritis report that nightshade vegetables, such as tomatoes, peppers, and eggplants, trigger flare-ups of joint pain and inflammation. While more research is needed to establish a clear link, individuals with psoriatic arthritis may consider limiting or avoiding nightshade vegetables if they notice symptom exacerbation. Experimenting with different vegetables and maintaining a food journal can help identify personal triggers and tailor a diet that minimizes discomfort.
