Generally, inflammation is a temporary - healing action in the body, responding to temporary illnesses, pathogens and allergies, or injuries; but autoimmune irregularities, severe allergies, or autoimmune-related illnesses can result in continuous, ongoing, chronic inflammation that must be monitored by SED rate tests to determine when it becomes dangerous or if causes have intensified the condition. In its chronic state, inflammation can become a disease and if it goes unchecked is a threat to life. In traditional medicine, the theory is that inflammation is a result and symptom - but that chronic inflammation may be a cause of other age-related or auto-immune disorders.
Traditional medicine is more likely to connect chronic inflammation to terminal and immune-system-related illnesses; while alternative medicine connects chronic inflammation to various other conditions - such as stress-related factors or chemicals in your food and the environment. Alternative medicine 'believes' medication itself - such as antibiotics can create an imbalance in the intestine and damage (sometimes irreversibly) the intestine and immune system but may be healed through nutrition.
Alternative medicine and most nutritionists advocate that a 'healthy diet' is one of the best defenses and healing devices for treating inflammation - and is increasingly advocated by traditional medicine as a standard treatment or containment of inflammation. Whenever new ideas and theories enter a traditional field, resistance to the new idea is normal - and there is often a lag before the idea is shared throughout the field and people's behavior impacted; but the idea that diet is important to health and healing has become typical in the genre of medicine.
There are many wonderful articles on diet for healing inflammation, and here are a couple for you to read:
