3. Crispy Culprits: Fried and Processed Foods

French fries, chicken nuggets, and other fried goodies contain advanced glycation end products (AGEs), harmful compounds that build up in the body over time and promote inflammation. Arthritis Care Australia explains, “Processed foods contain high levels of sugar, salt, preservatives and flavor enhancers, which aggravate joint inflammation in those who suffer from arthritis. Avoid deep-fried foods, commercially baked goods, and prepackaged meals.” These convenience foods also often contain trans fats, which are particularly problematic for people with arthritis.
