Foods to Avoid to Prevent Psoriatic Arthritis Flare-Ups

1. Red Meat

Red meat, including beef, pork, and lamb, is high in saturated fats, which are known to stimulate the body’s inflammatory pathways. Research has shown that diets rich in red meat can elevate inflammatory markers such as C-reactive protein (CRP), contributing to worsened symptoms in people with psoriatic arthritis. A study published in Nutrients highlighted that individuals consuming higher amounts of red meat tend to experience greater inflammation compared to those following plant-based or Mediterranean diets, which emphasize lean proteins and whole foods. To help prevent flare-ups, it is advisable to limit red meat intake to occasional servings, opting instead for alternatives like fish, poultry, legumes, and plant-based proteins. If you do consume red meat, choosing lean cuts and smaller portions can further reduce the potential for inflammation. Incorporating more vegetables, whole grains, and healthy fats into your diet can help counterbalance the negative effects of saturated fats. For additional guidance, the Arthritis Foundation recommends focusing on an anti-inflammatory diet as part of an overall strategy to manage psoriatic arthritis.

2. Processed Meats

Processed meats, such as sausages, hot dogs, bacon, and deli meats, are often loaded with nitrates, nitrites, and various preservatives designed to extend shelf life and enhance flavor. These additives have been linked to increased inflammation in the body, a particular concern for those with psoriatic arthritis. According to the World Health Organization, regular consumption of processed meats is a known risk factor not only for chronic diseases like cancer and cardiovascular disease, but also for inflammatory conditions. The pro-inflammatory effects are believed to stem from the combination of unhealthy fats, high sodium content, and chemical preservatives. For individuals with psoriatic arthritis, these factors may intensify joint pain and swelling, exacerbating flare-ups. Healthier protein alternatives include fresh poultry, fish rich in omega-3 fatty acids, or plant-based options such as lentils, beans, and tofu. These choices provide essential nutrients without the inflammatory risks associated with processed meats. For more information on making anti-inflammatory dietary choices, the Arthritis Foundation’s guide offers practical tips on incorporating healthier proteins into your meals.

3. Fried Foods

Fried foods, including items like French fries, fried chicken, and doughnuts, are typically cooked in oils at high temperatures, resulting in the formation of unhealthy trans fats. These trans fats are notorious for promoting inflammation and increasing the risk of chronic diseases, which can worsen psoriatic arthritis symptoms. According to the Harvard T.H. Chan School of Public Health, trans fats not only raise bad cholesterol (LDL) but also lower good cholesterol (HDL), compounding their negative impact on overall health and inflammation. Comparatively, baked alternatives use little or no added fat and do not undergo the same chemical changes that occur during frying, making them a healthier choice for those aiming to reduce inflammation. Swapping fried foods for baked, grilled, or steamed options can significantly lower your intake of trans fats and saturated fats, helping to manage joint pain and reduce the frequency of flare-ups. Using healthy oils, such as olive or avocado oil, and exploring air-frying as a lower-fat method can also make a difference.

According to the Centers for Disease Control and Prevention (CDC), all forms of added sugar, including honey and syrups, should be consumed in moderation to prevent chronic inflammation and related health risks.

While honey and maple syrup do contain small amounts of beneficial antioxidants and minerals that are not found in refined sugar, their effects on inflammation and metabolic health are largely the same when used in excess. Both should be viewed as occasional treats rather than everyday staples. Using smaller amounts, or substituting with naturally sweet foods like fruit, can help satisfy sweet cravings while keeping inflammation in check. For more advice on reducing added sugars and making anti-inflammatory dietary changes, consult the Arthritis Foundation’s healthy sugar swaps guide.

35. Restaurant Chinese Food

Restaurant Chinese food, especially dishes from takeout or buffet menus, is often high in sodium, monosodium glutamate (MSG), and added sugars. These ingredients are used to enhance flavor and preserve freshness but can contribute to increased inflammation and potential flare-ups for those with psoriatic arthritis. According to the Centers for Disease Control and Prevention (CDC), restaurant meals are among the leading sources of excess dietary sodium, which can trigger immune activation and promote fluid retention. MSG, a common flavor enhancer, may also cause sensitivity reactions in some people, potentially worsening joint pain or swelling.

Homemade Chinese-inspired meals allow you to control the ingredients and reduce salt, sugar, and MSG. Opt for stir-fries with fresh vegetables, lean proteins like chicken or tofu, and low-sodium soy sauce or tamari. Using ginger, garlic, and herbs for flavor can reduce the need for added salt and sugar. When ordering at a restaurant, request sauces on the side, choose steamed dishes, and avoid deep-fried or heavily sauced options. For more tips on making healthy restaurant choices and preparing anti-inflammatory meals at home, see the Arthritis Foundation’s diet guide.

36. Deli Meats

Deli meats, including ham, turkey, salami, and roast beef, are convenient protein sources but are often laden with preservatives, salt, and unhealthy fats. Common additives such as nitrates and nitrites help preserve color and shelf life but have been linked to increased inflammation and a greater risk of chronic disease. The high sodium content in deli meats can also contribute to fluid retention and stimulate immune system activity, exacerbating psoriatic arthritis symptoms. According to the Centers for Disease Control and Prevention (CDC), processed meats like deli cuts are a leading source of sodium and saturated fat in the American diet.

Freshly cooked meats, such as grilled chicken breast, baked turkey, or roasted lean beef, offer a healthier alternative with far fewer additives and lower sodium content. These options allow you to control seasoning and avoid preservatives entirely. For those managing psoriatic arthritis, prioritizing unprocessed protein sources—like fresh poultry, fish, legumes, and tofu—can help reduce inflammation and support overall health. When purchasing meat, look for “no added nitrates/nitrites” or “low sodium” labels and avoid heavily processed varieties.
