Inflammation is your body’s response to injury or infection and helps keep you healthy. But when inflammation lasts too long, it can become harmful. Chronic inflammation has been linked to a range of health conditions, including diabetes, heart disease, and arthritis. This report explains what chronic inflammation is, why it matters, and what kinds of everyday steps can help reduce it. These include physical activity, avoiding tobacco, and reducing harmful exposures. Food also plays a major role, and many nutrients that both cause and can reduce inflammation can be found in what we eat. Reducing inflammation often involves the same choices we make to prevent other chronic diseases, and small changes can make a meaningful difference over time.
