When is CRP Ernährung actually useful?

CRP (C-reactive protein) is a non-specific marker of inflammation. Using it to guide nutrition is useful when persistently elevated levels indicate a chronic low-grade inflammatory state – e.g., in obesity, metabolic syndrome, or subclinical inflammation. Evidence suggests that anti-inflammatory diets (Mediterranean, high in omega-3s, fiber, low in ultra-processed foods) can lower CRP. However, CRP alone is not diagnostic; it must be interpreted alongside lifestyle factors, infections, and other clinical data. Single measurements are unreliable – serial testing after a defined dietary intervention is more meaningful. The evidence is moderate: RCTs show dietary effects on CRP, but optimal cut-offs and individual responses vary. Caveat: CRP can rise due to non-dietary factors like poor sleep, stress, or hidden infections. A CRP test is not a substitute for medical evaluation.
