A healthy diet is a powerful tool in managing rheumatoid arthritis (RA), an autoimmune condition causing joint inflammation, pain, and damage. While diet alone cannot cure RA, avoiding specific pro-inflammatory foods can help reduce symptoms and improve overall well-being. By making informed dietary choices, you can minimize triggers and support your body's anti-inflammatory defenses.
Refined sugars and simple carbohydrates
Excessive sugar consumption is a key driver of inflammation. When you eat foods with high levels of added sugar, your body produces inflammatory messengers called cytokines. This can exacerbate existing inflammation in the joints of those with RA. Simple carbohydrates, such as those found in white bread, white rice, and pastries, are quickly broken down into sugar by the body, causing blood sugar spikes and further promoting inflammation.
- Foods to limit:
- Sugary drinks (soda, sweetened fruit juices, energy drinks)
- Candy, desserts, and pastries
- White bread, pasta, and white rice
Processed and red meats
Processed and red meats contain high levels of saturated fat and other additives that can trigger inflammation. Studies have linked high red meat intake to increased inflammatory biomarkers like interleukin-6 (IL-6) and C-reactive protein (CRP). For individuals with RA, choosing lean protein sources or plant-based alternatives can be a healthier option.
- Processed meats:
- Bacon, sausages, and hot dogs
- Deli meats and cured hams
- Red meats:
- Beef, pork, and lamb
Fried foods and trans fats
Fried foods are often cooked in oils rich in omega-6 fatty acids, and many processed foods contain trans fats. A high ratio of omega-6 to omega-3 fatty acids can promote inflammation, worsening RA symptoms. Fried foods and trans fats also contribute to obesity, which puts additional stress on the joints.
- Avoid:
- French fries and fried chicken
- Margarine, shortening, and lard
High-salt foods
Consuming too much salt has been associated with increased inflammation and a higher risk of developing RA, especially for individuals on steroid medication. Many processed foods, canned soups, and fast-food items are loaded with excessive sodium, which can intensify RA symptoms.
- Sodium sources to watch:
- Canned and packaged soups
- Processed snacks like chips and crackers
- Fast food
Advanced Glycation End products (AGEs)
AGEs are inflammatory compounds that form when proteins or fats react with sugars, particularly under high-temperature, low-moisture cooking methods like grilling or frying. Foods high in AGEs include grilled meats, broiled hot dogs, and hard cheeses. Reducing your intake of these foods can help lower overall oxidative stress and inflammation.
The role of gluten and dairy
Some individuals with RA may find that gluten and dairy products trigger inflammation and worsen their symptoms, though the research is mixed. Gluten is a protein in wheat, barley, and rye, while dairy contains the protein casein. If you suspect a sensitivity, an elimination diet, conducted under medical supervision, can help determine if these foods are contributing to your flares.
Inflammatory vs. Anti-inflammatory Foods for RA
| Food Type | Inflammatory Choice (Worsens RA) | Anti-inflammatory Choice (Helps RA) |
|---|---|---|
| Carbohydrates | White bread, pasta, pastries | Whole grains like oats, quinoa, brown rice |
| Protein | Processed meats (bacon, sausage) | Fatty fish (salmon, tuna), lean poultry |
| Fats | Vegetable oils (corn, safflower) | Olive oil, omega-3 rich foods |
| Drinks | Sugary sodas, fruit juices | Water, green tea |
| Snacks | Chips, sugary cookies | Nuts, seeds, fresh fruit |
Adopting a diet for RA management
Making a dietary shift to reduce RA symptoms is a proactive and beneficial step. Focus on whole, unprocessed foods and a balanced intake of nutrients, similar to a Mediterranean-style diet. A diet rich in fruits, vegetables, whole grains, nuts, and healthy fats can help combat inflammation and support a healthy weight, which further eases joint stress. Always consult with a healthcare professional or a registered dietitian before making significant dietary changes, especially if you are on RA medication, as some foods or supplements can interact with your treatment.

Conclusion
Understanding what foods make RA worse allows for a more personalized and effective management strategy. By systematically reducing your intake of refined sugars, processed and red meats, fried foods, and high-salt products, you can help lower systemic inflammation and potentially reduce the frequency and severity of RA flares. While individual responses to certain foods like gluten and dairy may vary, focusing on a nutrient-dense, anti-inflammatory diet is a generally accepted approach to supporting joint health and improving overall quality of life with RA.
