Foods to Avoid If You Have Arthritis

17. Soda and Sugary Drinks

Sugary beverages, including soda, sweetened teas, and flavored coffee drinks, are packed with refined sugar and artificial sweeteners. Excess sugar consumption is linked to increased inflammation and higher levels of C-reactive protein (CRP), a marker of inflammation commonly elevated in arthritis patients. A study published in The American Journal of Clinical Nutrition found that women who drank just one sugary soda per day had a significantly increased risk of developing rheumatoid arthritis. Choosing water, herbal teas, or infused water with fresh fruits is a healthier alternative that supports hydration and joint health.

18. High-Sodium Foods

Salt is necessary for bodily functions, but excessive sodium intake can worsen arthritis symptoms. A diet high in processed, salty foods contributes to water retention and increased inflammation, making joint pain and swelling more severe. Many arthritis medications can already cause sodium retention, further compounding the issue. A study published in Nature Communications found that high-salt diets can activate inflammatory cells in autoimmune conditions. Avoiding processed foods like canned soups, frozen meals, and salty snacks while seasoning meals with herbs and spices instead can help manage arthritis symptoms more effectively.
