Even if you don't need to get your CRP measured, there's a good reason to make the lifestyle changes that appear to help limit inflammation.
Control weight, stay active. Simply digesting your food seems to trigger temporary inflammation—and the bigger the meal, the higher the CRP level might climb. Excess weight worsens the problem, since fat cells, especially around the gut, produce inflammatory proteins. On the other hand, people who lose weight tend to lower their CRP level. And exercise generates inflammation-fighting proteins, so it might help fight inflammation even if you don't lose weight.
Eat a heart-healthy diet. Saturated fat (from meat and dairy products) and trans fats (from partially hydrogenated oils) can raise the CRP level. Fruit, vegetables, whole grains, and the omega-3 fatty acids in fish might help lower it.
Manage stress. The CRP level and other markers of inflammation rise after stressful events and might be consistently elevated in people who experience chronic stress, loneliness, or, as an Israeli study found, constant fear. Other research has linked depression with elevated CRP levels.
Quit smoking. Smoking might harm the arteries in part by causing inflammation.
Rein in infection. Research hints that a bacterium known as H. pylori, as well as germs that cause periodontal disease, influenza, pneumonia, and the sexually transmitted disease chlamydia, might increase the risk of heart disease. It makes sense to protect yourself against those infections and others. So talk with your doctor about getting vaccinated against influenza, pneumonia, hepatitis B and, if you're a woman, the human papilloma virus (HPV). Finally, practice good dental hygiene and take steps to avoid sexually transmitted diseases or get treatment for them.
