Connecting the dots: hs-CRP and dietary inflammatory scores for advanced inflammation management

The clinical benefits of testing hs-CRP alongside food IgG testing for nutrition practitioners lie primarily in improved detection and management of inflammation and food sensitivities, leading to better patient outcomes.

hs-CRP as a Marker for Inflammation and Cardiovascular Risk

High-sensitivity C-reactive protein (hs-CRP) is a sensitive biomarker of low-grade systemic inflammation. Its common practice in nutritional therapy to use hs-CRP testing to assess chronic inflammation, which plays a key role in chronic diseases as well as driving the aging process. As such, hs-CRP testing provides crucial information to guide preventive interventions including dietary and lifestyle changes.[1][2]

Complementary Clinical Utility of Testing Together

Combining hs-CRP with food IgG testing offers a more comprehensive clinical picture. Food sensitivities identified by IgG testing may contribute to systemic inflammation detectable through hs-CRP. Measuring hs-CRP provides an objective biomarker to monitor the inflammatory impact of IgG-identified foods and the effectiveness of elimination diets. For instance, a baseline hs-CRP test taken with an IgG panel before dietary changes and a follow-up test after three months can help practitioners evaluate the success of interventions and motivate patient adherence.[4]

Dietary Influence on Inflammation

Both hs-CRP levels and IgG reactivity are influenced by diet quality. Evidence shows that consumption of fruits, vegetables, fiber, and nutrients like vitamin C and folate is inversely correlated with hs-CRP levels, while foods high in saturated fat, refined carbohydrates and sugar such as ultra-processed foods, as well as alcohol intake may raise it. Therefore, nutrition practitioners can use hs-CRP as a biomarker to tailor diets that reduce inflammation, alongside the elimination of specific IgG-reactive foods.[5][6][7]

Practical Benefits for Patient Outcomes

Integrating hs-CRP testing with food IgG panels equips nutrition practitioners with enhanced tools to identify, quantify, and manage inflammation tied to food sensitivities. This dual testing strategy facilitates personalised nutrition care, improves adherence to intervention plans, and ultimately supports better long-term patient outcomes.
