1. Nightshade vegetables
Nightshade vegetables such as tomatoes, potatoes, peppers, and eggplant contain a compound called solanine, which some people believe can contribute to inflammation in the body. If you notice that consuming nightshade vegetables worsens your psoriatic arthritis symptoms, you may want to consider eliminating them from your diet.
2. Gluten
Gluten is a protein found in wheat, barley, and rye. Some people with psoriatic arthritis may have a sensitivity to gluten, which can trigger inflammation and exacerbate joint pain. Consider opting for gluten-free alternatives like quinoa, rice, or corn if you suspect gluten may be a problem for you.
3. Sugar and refined carbohydrates
Foods high in sugar and refined carbohydrates, such as candy, pastries, white bread, and sugary drinks, can cause spikes in blood sugar levels and promote inflammation. Try to limit your intake of these foods and opt for healthier alternatives like fruits, vegetables, and whole grains.
4. Red meat and processed foods
Red meat and processed foods like bacon, sausage, and deli meats are high in saturated fats and may contribute to inflammation in the body. Instead, choose lean proteins like fish, poultry, tofu, or legumes for a healthier option.
