How Knowing Your CRP Could Save Your Life
Updated: Apr 11, 2019
What is CRP – and why should you care about it?
C-reactive protein (CRP) is a protein found in the blood that is an accurate biomarker for inflammation in your body – both general inflammation, as well as cardiac-related inflammation.
It is measured by a simple blood test called high-sensitivity C-reactive protein (hsCRP).
An otherwise healthy individual who has a high hsCRP level is four times more likely to have heart and blood vessel disease.
In another large study, the Physicians’ Health Study of 18,000 healthy physicians, an elevated CRP level was associated with a 3-fold increase in heart attack risk. In a subgroup of these physicians, a high level of CRP was associated with peripheral artery disease, even in participants who had normal cholesterol levels.
Where does this inflammation come from?
Inflammation can come from a variety of inflammatory conditions in the body including environmental pollutants, food sensitivities, increased intestinal permeability, heavy metals accumulations as well as undiscovered or untreated fungal, bacterial and viral infections including periodontal disease.
A Mayo Clinic study found that the greater the severity of rheumatoid arthritis, the greater the risk for heart disease.
Lifestyle factors, particularly diet, make a big contribution to the inflammatory burden in your body. Some of these risk factors include:
Eating fast food. Eating fast food just one time a week could spike your CRP.
Smoking – including e-cigarettes and possibly marijuana
Being a couch potato
Eating sugary desserts
Drinking soda pop
Eating deep-fried foods
Eating foods containing partially hydrogenated oils
If you do have signs of high inflammation in your body, then what can you do about it?
So many conditions yet one central causative factor: inflammation. The silver lining is that anything you can do to quench the inflammation should also help you in multiple ways. So what can you do?
Eat an anti-inflammatory diet:
Fatty fish high in omega-3 fatty acids at least twice a week (trout, salmon, sardines, anchovies, mackerel)
Olive oil – for sautéing and in salad dressings
Liberal use of anti-inflammatory spices – like turmeric, ginger, cayenne, cinnamon, clove, sage, and rosemary
Plenty of green, yellow, and orange vegetables
Dark red, blue, and purple berries
Avoid foods you know you are allergic (or even sensitive) to, since these adverse food reactions will feed inflammation.
Move to improve CRP levels
The most potent anti-inflammatory known to woman or man? Believe it or not, it's called moving around. Regular, moderately intense exercise can significantly lower your CRP. For example, one 12-week study in women who had type 2 diabetes found that aerobic exercise – starting with 8 minutes of jogging and 8 minutes of running and working up to 32 minutes – significantly decreased CRP and other biomarkers of inflammation.
Yoga and meditation are the most often mentioned options to lower stress, but it doesn't have to be all so serious. Gardening, wood working, baking, heck fishing! Any focused activity where you lose all sense of time because you either love it (or, in the case of yoga, hate it when you're in those grueling long held asanas!) so much. One study found that one hour of yoga daily, six days a week for three months, lowered CRP. Reduce environmental stress by exercising indoors in areas free of smoke, smog, and pollution.
Thorne’s Heart Health At-Home Test uses a simple finger-stick blood-spot test to measure CRP levels (using hsCRP technology), along with levels of triglycerides, insulin, HbA1C, and a couple of cholesterol markers. Or you could ask your MD next time you're in for a check-up.
