Dietetics After Spinal Cord Injury: Current Evidence and Future Perspectives

Spinal Cord InjuryNutrition & Dietetics

Simple Explanation

Following a spinal cord injury (SCI), individuals are at high risk for obesity and several chronic cardiometabolic disorders due to a deterioration in body composition, hypometabolic rate, and endometabolic dysregulation. A proper diet for individuals with SCI should distribute carbohydrates, protein, and fat to optimize a lower energy intake requirement and should stress foods with low caloric yet high nutrient density. The purpose of this article is to present available evidence on how nutritional status after SCI should advance future research to further develop SCI-specific guidelines for total energy intake, as it relates to percent carbohydrates, protein, fat, and all vitamins and minerals, that take into consideration the adaptations after SCI.

Key Findings

  • 1
    Energy intake in persons with SCI ranges from 1250 to 2112 kcal/day, although this is contingent on the frequency and reporting accuracy of the dietary recall questionnaires used to asses caloric intake.
  • 2
    Several studies indicate that the consumption of fruits and vegetables is below the recommended intake for persons with SCI; in their place, simple carbohydrates are frequently consumed.
  • 3
    Studies have demonstrated that individuals with SCI ingest levels of dietary fat that approach or surpass recommended guidelines.

Research Summary

SCI is associated with alterations in body composition, endometabolic complications, and malnutrition that are also cause for severe comorbidities. Although authoritative guidelines for nondisabled individuals provide dietary recommendations, they are likely inappropriate (i.e., underestimated or overestimated) for individuals with SCI because of reduced metabolic requirements, gut dysmotility, and sympathetic nervous system dysfunction. Future research should begin to explore the interactive effects of macronutrients rather than the absolute consumption of each macronutrient (i.e., nutrient intake) and how dietary intervention alone can improve rates of obesity and CMS in persons with SCI.

Practical Implications

Individualized Nutrition Plans

Emphasize personalized nutrition assessment and intervention due to the variability in injury characteristics and accessibility factors affecting nutritional status after SCI.

Macronutrient Balance

Explore the interactive effects of macronutrients to optimize dietary interventions for obesity and cardiometabolic syndrome in individuals with SCI.

Dietary Guidelines Revision

Modify existing dietary guidelines to account for the unique metabolic and physiological changes in individuals with SCI, considering factors like reduced metabolic needs and gut dysmotility.

Study Limitations

  • 1
    Reliance on self-reported dietary intake
  • 2
    Limited randomized controlled trials assessing specific dietary interventions
  • 3
    Inconsistent criteria for diagnosing malnutrition after SCI
