Essentially, it is a <a href=\"https:\/\/doi.org\/10.1056\/NEJMra2206346\">marker of inflammation<\/a> \u2013 meaning <a href=\"https:\/\/theconversation.com\/what-is-inflammation-two-immunologists-explain-how-the-body-responds-to-everything-from-stings-to-vaccination-and-why-it-sometimes-goes-wrong-193503\">immune system activation<\/a> \u2013 in the body.<\/p>\n\n\n\n<p>C-reactive protein can be easily measured with blood work at the doctor\u2019s office. A low C-reactive protein level \u2013 under 1 milligram per deciliter \u2013 signifies minimal inflammation in the body, which is protective against heart disease. An elevated C-reactive protein level of greater than 3 milligrams per deciliter, signifies increased levels of inflammation and thus <a href=\"https:\/\/doi.org\/10.3390\/biomedicines11092444\">increased risk for heart disease<\/a>. About 52% of Americans have an <a href=\"https:\/\/doi.org\/10.1056\/NEJM200504143521525\">elevated level of C-reactive protein<\/a> in their blood.<\/p>\n\n\n\n<p>Research shows that C-reactive protein is a better predictive marker for heart attacks and strokes than <a href=\"https:\/\/doi.org\/10.1056\/NEJMoa2405182\">\u201cbad,\u201d or LDL cholesterol, short for low-density lipoprotein<\/a>, as well as another commonly measured genetically inherited biomarker called <a href=\"https:\/\/doi.org\/10.1056\/nejmoa2405182\">lipoprotein(a)<\/a>. One study found that C-reactive protein <a href=\"https:\/\/doi.org\/10.1016\/S0140-6736(09)61717-7\">can predict heart disease just as well as blood pressure can<\/a>.<\/p>\n\n\n\n<h2>Why does inflammation matter in heart disease?<\/h2>\n\n\n\n<p>Inflammation plays a crucial role at every stage in the development and buildup of fatty plaque in the arteries, which causes a condition called <a href=\"https:\/\/www.mayoclinic.org\/diseases-conditions\/arteriosclerosis-atherosclerosis\/symptoms-causes\/syc-20350569\">atherosclerosis<\/a> that can <a href=\"https:\/\/doi.org\/10.1161\/hc0902.104353\">lead to heart attacks and strokes<\/a>.<\/p>\n\n\n\n<p>From the moment a blood vessel is damaged, be it <a href=\"https:\/\/doi.org\/10.5772\/intechopen.71433\">from high blood sugar<\/a> or <a href=\"https:\/\/doi.org\/10.1046\/j.1365-2613.2000.00162.x\">cigarette smoke<\/a>, immune cells immediately infiltrate the area. Those immune cells subsequently engulf cholesterol particles that are typically floating around in the blood stream to form a fatty plaque that resides in the wall of the vessel.<\/p>\n\n\n\n<p>This process continues for decades until eventually, one day, immune mediators rupture the cap that encloses the plaque. This triggers the formation of a blood clot that obstructs blood flow, starves the surrounding tissues of oxygen and ultimately causes a heart attack or stroke.<\/p>\n\n\n\n<p>Hence, cholesterol is only part of the story; it is, in fact, the immune system that facilitates each step in the processes that drive heart disease.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><a href=\"https:\/\/images.theconversation.com\/files\/709797\/original\/file-20251218-56-78eb52.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip\"><img src=\"https:\/\/images.theconversation.com\/files\/709797\/original\/file-20251218-56-78eb52.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip\" alt=\"Three-dimensional concept of fatty plaque buildup in an artery.\"\/><\/a><figcaption>Fatty plaque buildup in the arteries causes a blockage that starves tissues of oxygen and can lead to a heart attack or stroke. <a href=\"https:\/\/www.gettyimages.com\/detail\/photo\/artery-plaque-royalty-free-image\/2208877625?phrase=heart%20disease%20risk&amp;searchscope=image%2Cfilm&amp;adppopup=true\">wildpixel\/iStock via Getty Images Plus<\/a><\/figcaption><\/figure>\n\n\n\n<h2>Can diet influence C-reactive protein levels?<\/h2>\n\n\n\n<p>Lifestyle can significantly influence the <a href=\"https:\/\/doi.org\/10.1177\/2047487319885458\">amount of C-reactive protein produced by the liver<\/a>.<\/p>\n\n\n\n<p>Numerous foods and nutrients have been shown to lower C-reactive protein levels, including <a href=\"https:\/\/doi.org\/10.3109\/09637486.2014.959898\">dietary fiber from foods like beans, vegetables, nuts and seeds<\/a>, as well as <a href=\"https:\/\/doi.org\/10.1016\/j.fct.2019.110922\">berries<\/a>, <a href=\"https:\/\/doi.org\/10.1080\/10408398.2025.2525446\">olive oil<\/a>, <a href=\"https:\/\/doi.org\/10.1016\/j.ctim.2019.08.019\">green tea<\/a>, <a href=\"https:\/\/doi.org\/10.1186\/s12986-024-00847-3\">chia seeds<\/a> and <a href=\"https:\/\/doi.org\/10.1016\/j.prostaglandins.2024.106868\">flaxseeds<\/a>.<\/p>\n\n\n\n<p><a href=\"https:\/\/doi.org\/10.1001\/archinte.167.1.31\">Weight loss<\/a> <a href=\"http:\/\/doi.org\/10.1136\/bjsports-2016-095999\">and exercise<\/a> can also reduce C-reactive protein levels.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><a href=\"https:\/\/images.theconversation.com\/files\/709795\/original\/file-20251218-56-si5ozt.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip\"><img src=\"https:\/\/images.theconversation.com\/files\/709795\/original\/file-20251218-56-si5ozt.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip\" alt=\"Colorful variety of foods that help lower heart disease risk.\"\/><\/a><figcaption>Diet plays a key role in heart disease risk. <a href=\"https:\/\/www.gettyimages.com\/detail\/photo\/food-products-representing-the-dash-diet-royalty-free-image\/2176934394?phrase=heart%20disease%20risk&amp;searchscope=image%2Cfilm&amp;adppopup=true\">monticelllo\/iStock via Getty Images Plus<\/a><\/figcaption><\/figure>\n\n\n\n<h2>Does cholesterol still matter for heart disease risk?<\/h2>\n\n\n\n<p>Though cholesterol may not be the most important predictor of risk for heart disease, it does remain highly relevant.<\/p>\n\n\n\n<p>However, it\u2019s not just the amount of cholesterol \u2013 or more specifically the amount of bad, or LDL, cholesterol \u2013 that matters. Two people with the same cholesterol level don\u2019t necessarily have the same risk for heart disease. This is because risk is determined more so by the number of particles that the bad cholesterol is packaged into, as opposed to the total mass of bad cholesterol that\u2019s floating around. <a href=\"http:\/\/doi.org\/10.1161\/CIRCULATIONAHA.124.068885\">More particles means higher risk<\/a>.<\/p>\n\n\n\n<p>That is why a blood test known as <a href=\"https:\/\/my.clevelandclinic.org\/health\/diagnostics\/24992-apolipoprotein-b-test\">apolipoprotein B<\/a>, which measures the number of cholesterol particles, is a better predictor of risk for heart disease than <a href=\"https:\/\/doi.org\/10.1001\/jamacardio.2021.5083\">measurements of total amounts of bad cholesterol<\/a>.<\/p>\n\n\n\n<p>Like cholesterol and C-reactive protein, apolipoprotein B is also influenced by lifestyle factors <a href=\"http:\/\/doi.org\/10.1055\/a-2580-0722\">like exercise<\/a>, <a href=\"http:\/\/doi.org\/10.1186\/s12944-019-1094-4\">weight loss<\/a> and diet. Nutrients like <a href=\"https:\/\/doi.org\/10.1017\/S0954422416000147\">fiber, nuts and omega-3 fatty acids<\/a> are associated with a decreased number of cholesterol particles, while <a href=\"https:\/\/doi.org\/10.3390\/nu9030211\">increased sugar intake is associated with a larger number<\/a> of cholesterol particles.<\/p>\n\n\n\n<p>Furthermore, <a href=\"https:\/\/www.heart.org\/en\/health-topics\/cholesterol\/genetic-conditions\/lipoprotein-a\">lipoprotein(a)<\/a>, a protein that lives in the wall surrounding cholesterol particles, is another marker that <a href=\"https:\/\/doi.org\/10.1161\/ATV.0000000000000147\">can predict heart disease more accurately than cholesterol levels<\/a>. This is because the presence of lipoprotein(a) makes cholesterol particles sticky, so to speak, and thus more likely to get trapped in an atherosclerotic plaque.<\/p>\n\n\n\n<p>However, unlike other risk factors, lipoprotein(a) levels are purely genetic, thus not influenced by lifestyle, and need only be measured once in a lifetime.<\/p>\n\n\n\n<h2>What\u2019s the best way to prevent heart disease?<\/h2>\n\n\n\n<p>Ultimately, heart disease is the product of many risk factors and their interactions over a lifetime.<\/p>\n\n\n\n<p>Therefore, preventing heart disease is way more complicated than <a href=\"https:\/\/doi.org\/10.1093\/jn\/128.2.449S\">simply eating a cholesterol-free diet, as once thought<\/a>.<\/p>\n\n\n\n<p>Knowing your LDL cholesterol level alongside your C-reactive protein, apolipoprotein B and lipoprotein (a) levels paints a comprehensive picture of risk that can hopefully help motivate long-term commitment to the <a href=\"https:\/\/www.heart.org\/en\/healthy-living\/healthy-lifestyle\/how-to-help-prevent-heart-disease-at-any-age\">fundamentals of heart disease prevention<\/a>. These include eating well, exercising consistently, getting adequate sleep, managing stress productively, maintaining healthy weight and, if applicable, quitting smoking.<\/p>\n\n\n\n<p><a href=\"https:\/\/theconversation.com\/profiles\/mary-j-scourboutakos-1518645\">Mary J.
