Vegan Diet and Erythrocyte Sedimentation Rate (ESR)
A vegan diet may help lower elevated ESR levels by reducing inflammation, particularly when followed for at least 2 years, as plant-based diets are associated with significantly lower concentrations of inflammatory markers. 1, 2
Mechanisms by Which Vegan Diets May Lower ESR
- Vegan diets contain various anti-inflammatory components that can help reduce systemic inflammation markers 1
- Plant-based diets are associated with significantly lower concentrations of C-reactive protein (CRP) (weighted mean difference: -0.61 mg/L), fibrinogen (weighted mean difference: -0.22 g/L), and total leukocyte count (weighted mean difference: -0.62 × 10³/μL) compared to non-vegetarian diets 2
- The anti-inflammatory effects of vegan diets appear to be time-dependent, with more significant reductions in inflammatory markers observed after following the diet for at least 2 years 1
Components of Vegan Diets That May Reduce Inflammation
- Vegan diets are typically higher in fruits, vegetables, whole grains, legumes, nuts, and seeds, which provide vitamins, minerals, phytochemicals, and antioxidants that promote immune function 3
- Plant-based diets are associated with lower intake of saturated fat and higher intake of dietary fiber, which can contribute to reduced inflammation 4
- The Western dietary pattern of high animal protein and low fruit and vegetable consumption creates an imbalance between nonvolatile acids and alkali, potentially leading to chronic low-grade metabolic acidosis that may contribute to inflammation 5
Cardiovascular and Metabolic Benefits That May Indirectly Affect ESR
- Vegan diets have been favorably connected with reduced body mass index (BMI), total serum cholesterol, serum glucose, and blood pressure 3
- Lower BMI and waist circumference are important factors influencing inflammatory state, which can affect ESR levels 6
- Plant-based dietary patterns are associated with a 20%-25% reduced risk of cardiovascular disease and type 2 diabetes, conditions often associated with elevated inflammatory markers 5
Potential Limitations and Considerations
- Some studies show no significant differences in inflammatory biomarkers (including hsCRP, IL-18, IL-1 RA, ICAM-1, adiponectin, omentin-1, and resistin) between vegans and omnivores 6
- Duration of vegan diet may be positively correlated with certain inflammatory markers like resistin, IL-18, and IL-1 RA 6
- Vegans need to ensure adequate intake of certain nutrients that may be limited in plant-based diets, including vitamin B12, vitamin D, omega-3 fatty acids, selenium, zinc, and iodine 3, 7
- Strict vegetarians who don't consume milk or eggs must ensure adequate intake of certain amino acids by consuming a complementary mix of plant proteins 5
Practical Implementation
- Focus on consuming a variety of plant foods to ensure adequate nutrient intake 5
- Include fortified foods or supplements, particularly for vitamin B12, which is found exclusively in animal products or fortified foods 7
- Ensure adequate protein intake through a complementary mix of plant proteins to provide all essential amino acids 5
- Consider monitoring inflammatory markers like ESR and CRP to assess the effectiveness of dietary changes 2
- Maintain the vegan diet for at least 2 years to potentially see more significant reductions in inflammatory markers 1
Monitoring and Follow-up
- Regular monitoring of ESR levels is recommended to assess the effectiveness of the dietary intervention 2
- Consider testing for vitamin B12 status using methylmalonic acid (MMA) levels and holotranscobalamin II levels 7
- Monitor for potential nutrient deficiencies that could occur with a vegan diet, particularly vitamin B12, vitamin D, omega-3 fatty acids, calcium, iron, and zinc 4
