What is high-sensitivity C-reactive protein? Can you lower it with food?
When we exercise regularly and eat well, focusing on heart-healthy whole foods as the Pritikin Eating Plan does, we’re not only taking good care of our hearts; we’re taking good care of all kinds of lesser-known but incredibly important heart-protective systems within us, like our ability to prevent chronic inflammation.
Within three weeks of eating and exercising Pritikin style, scientists at UCLA documented that hs-CRP levels fell on average 39% in men,1 45% in women,2 and 41% in children.3
The Pritikin Eating Plan focuses on whole foods naturally rich in fiber and low in salt and sugar, such as fresh fruit, fresh vegetables, and whole grains, and lean sources of protein like beans/legumes, fish, white poultry, egg whites, and nonfat dairy foods.
Biomarker of cardiovascular disease risk
In recent years, hs-CRP has been endorsed by several public health organizations4,5,6 as a biomarker of cardiovascular disease risk.
What is hs-CRP?
High-sensitivity C-reactive protein is produced by the body when blood-vessel walls are inflamed. The higher your levels of hs-CRP, the higher your levels of inflammation tend to be.
But before we go any further, it’s important to distinguish between acute inflammation and chronic inflammation.

Acute inflammation
Inflammation can be a very good thing. Think of inflammation like a burner on a gas stove. When you suffer an injury, like a cut on your finger, your body turns up the flame. Your immune system sends in an army of white blood cells that fight infection and promote healing. This is called local or acute inflammation.
Chronic inflammation
But problems can occur for the arteries and heart when your body keeps that burner going.
This low, steady burn, known as chronic inflammation, is not caused by a single injury, like a close encounter with a paring knife. Rather, it’s the result of constant injury to the inner walls of our arteries, and it’s brought on by lifestyle factors like poor food choices that lead to excess bad cholesterol in the blood, excess blood glucose, and high blood pressure.
Chronic inflammation in the arteries creates a breeding ground for the formation of fatty streaks, which can eventually lead to cholesterol-rich plaques and ultimately, heart attacks and strokes.
Many other diseases are also linked with chronic inflammation, and include arthritis, autoimmune diseases, cancer, diabetes, and pulmonary diseases.
Lowering hs-CRP
That’s why it’s so critical to focus on lowering inflammatory markers like high-sensitivity C-reactive protein.
Your hs-CRP score | What to aim for
A large clinical trial demonstrated significantly less cardiovascular risk for patients with hs-CRP scores that were less than 2.0 mg/L.7
General guidelines for hs-CRP scores:
- Low risk of cardiovascular disease: Less than 1.0 mg/L
- Average risk: 1.0 to 3.0 mg/L
- High risk: Above 3.0 mg/L
Above 10 mg/mL usually indicates acute inflammation.
What is the difference between CRP and hs-CRP?
As you’ve no doubt guessed, the difference between CRP and hs-CRP is contained in the “hs” abbreviation – “high sensitivity.”
Traditionally, CRP, or C-reactive protein, is measured down to concentrations of 3 to 5 mg/L; hs-CRP is measured down to concentrations of approximately 0.3 mg/L. This improved sensitivity allows hs-CRP to be used to detect low levels of chronic inflammation.
Other markers of chronic inflammation
Other markers of chronic inflammation include noxious chemicals released by both white blood cells and fat cells. They’re called inflammatory cytokines.
In a 2013 study on overweight and normal-weight children at the Pritikin Longevity Center, scientists at UCLA found that within two weeks, levels of inflammatory cytokines dropped markedly.8 Similar results published in several studies over the past decade have been observed in adults attending the Pritikin Longevity Center.
