•  Processed Foods: If you read the label on a packaged meal or snack, and half of the ingredients are chemicals or words you don’t know, you should steer clear. Processed foods contain advanced glycation end products (AGEs), and too much of this chemical can accumulate in the bloodstream and trigger inflammation. 
• Alcohol: While not a food, alcohol does cause major inflammation in the body. It causes acute or chronic inflammation due to a protein called C-reactive protein (CRP), and the more CRP that is present in the blood, the more inflammation. 
• Red Meat:  Multiple conditions in arthritis, especially inflammatory arthritis like gout and rheumatoid, have been linked to high fat intake or high red meat intake. To help reduce pain, swelling, and joint inflammation, try going meatless at least most of the week. But if you do eat red meat, reduce your portion sizes. Treat meat as a side dish, rather than the main attraction. 
• Refined Carbohydrates: Complex carbohydrates like oatmeal, quinoa, barley, and sweet potatoes are needed for energy, but refined carbs like sugary breakfast cereals, white bread, white rice, pastries, and pasta, may worsen arthritis symptoms
