This page talks about all the research I have done in regards to inflammation of the body. Inflammation puts your body at risk for disease, including cancer and heart disease, two of the big killers.
In regards to diet, you can make sure you eat a couple of servings of fish each week to get your Omega 3 fatty acids in, which will help your body fight unwanted inflammation. I also belive the more pure you can eat, the better it is for your body overall. Toxins will cause a response from your body which will cause inflammation. Being overweight is another risk factor for chronic inflammation. Regular exercise not only gives your body a chance to fight inflammation, but also makes you less likely to become obese.
