Chicken Stock and ESR Levels
There is no scientific evidence supporting that chicken stock can lower elevated Erythrocyte Sedimentation Rate (ESR) levels. While chicken soup has been studied for certain anti-inflammatory properties, no research demonstrates its ability to reduce ESR specifically.
Understanding ESR
- ESR is a non-specific marker of inflammation that measures how quickly red blood cells settle in a test tube over one hour 1
- Normal ESR values are typically below 20 mm/h in men and below 30 mm/h in women 1
- Moderate elevation (50-100 mm/h) suggests significant underlying disease 1
- ESR values exceeding 100 mm/h have a 90% predictive value for serious underlying disease, most often infection, collagen vascular disease, or metastatic tumor 2
Factors Affecting ESR
- Women typically have higher baseline ESR values than men 1
- Anemia and azotemia can artificially elevate ESR values 1
- ESR lacks sensitivity and specificity as a standalone test 2, 3
- ESR has a longer half-life than CRP, making it more useful for monitoring chronic inflammatory conditions rather than acute changes 4
Clinical Applications of ESR
- ESR is particularly useful in monitoring conditions such as giant cell arteritis and polymyalgia rheumatica 1
- For giant cell arteritis, an ESR >40 mm/h has high sensitivity (93.2%), while ESR >100 mm/h has high specificity (92.2%) 1
- ESR is used in disease activity scores for rheumatoid arthritis 1
- In inflammatory bowel disease, ESR correlates with disease activity in ulcerative colitis 5
- ESR values >60 mm/h are typical in acute rheumatic fever 5
Chicken Soup Research
- One study found that chicken soup inhibits neutrophil chemotaxis in vitro, suggesting mild anti-inflammatory properties 6
- This research demonstrated that chicken soup inhibited neutrophil migration in a concentration-dependent manner 6
- Both the vegetables and chicken components individually showed inhibitory activity 6
- However, this study did not measure effects on ESR levels 6
Management of Elevated ESR
- Treatment should target the underlying cause of inflammation rather than the ESR itself 1, 5
- For giant cell arteritis, early initiation of high-dose glucocorticoid therapy is recommended 7
- In inflammatory bowel disease, TNF inhibitors may be used for moderate-to-severe disease 7
- For rheumatic conditions, NSAIDs are effective but not recommended for long-term use 7
Limitations of ESR Testing
- ESR should not be used to screen asymptomatic persons for disease 2
- In the elderly, ESR may be as high as 35-40 mm/h in healthy individuals 8
- About 25% of elderly patients with malignant or non-malignant disease may have ESR below the upper normal limit 8
- If an increased ESR is encountered with no apparent explanation, clinicians should repeat the test in several months rather than pursue an exhaustive search for occult disease 2
Conclusion
While chicken soup has been studied for potential anti-inflammatory effects, there is no evidence that chicken stock specifically lowers ESR levels. Elevated ESR should be evaluated for underlying causes, and appropriate medical treatment should be directed at the primary condition rather than attempting to lower ESR with dietary interventions.
