Brief Summary:
Spinal cord Injury (SCI) is a condition commonly associated with a state of chronic low-grade inflammation due to a variety of factors such heightened risk for infection and development of metabolic disorders. Many disorders which have been demonstrated to have an inflammatory basis have also been found to be at much higher prevalence following SCI. Such conditions include, but are not limited to, depression, cognitive impairment, neuropathic pain, and somatic/autonomic nerve function. The fact that such disorders have an inflammatory basis provides a unique opportunity to treat them with intervention strategies which target the immune system. Natural anti-inflammatory interventions including a diet consisting of foods and supplements with anti-inflammatory properties may be an effective option for treating inflammation in this population. As this treatment strategy will target the inflammatory basis of many disorders it would be expected to lead to a reduction in pro-inflammatory mediators thereby leading to more sustainable long-term immune improvements regarding enzyme function and protein balances. Despite this, surprisingly little research has focused on the use of anti-inflammatory foods for the treatment of chronic inflammatory conditions, and effects specific to SCI have been almost completely neglected. As such, the current study will focus on the daily intake of natural supplements with anti-inflammatory properties over a 3 month intervention and the effects on inflammation and associated disorders will be assessed. It is hypothesized that the supplementation will result in positive alterations in enzyme regulation and protein balances resulting in improvements in each of the outcome measures of interest.

Primary Outcome Measures :
  1. Change from baseline in nerve conduction velocity of somatic nerves at 3 and 6 months [ Time Frame: Baseline / 3 months / 6 months ]
    Assessment of motor and sensory nerve conduction velocity via electrically evoked potentials of the median nerve

Secondary Outcome Measures :
  1. Change in baseline in autonomic function scores on the Autonomic Standards Assessment Form at 3 and 6 months [ Time Frame: Baseline / 3 months / 6 months ]
    Questionnaire pertaining to urinary, bowel, and sexual function

  2. Change in baseline pain scores on the Neuropathic Pain Questionnaire at 3 and 6 months [ Time Frame: Baseline / 3 months / 6 months ]
    Questionnaire pertaining to the type of pain felt (eg. burning, stabbing, throbbing), how the pain affects the participant (eg. ability to perform activities of daily living), and how various stimuli may increase pain (eg. increased pain due to heat).

  3. Change in baseline concentrations of pro-inflammatory eicosanoids at 3 and 6 months [ Time Frame: Baseline / 3 months / 6 months ]
    The potent pro-inflammatory and pain inducing eicosanoids prostaglandin-2 (PGE2) and leukotriene-4 (LTB4) as well as the less potent eicosanoids prostaglandin-3 and leukotriene-5 (LTB5) will be assessed.

  4. Change in baseline depression scores on the Centre for Epidemiological Studies Depression Scale at 3 and 6 months [ Time Frame: Baseline / 3 months / 6 months ]
    Questionnaire pertaining to how often participants felt a variety of depressive symptoms over the previous 7 days.

  5. Change in baseline concentrations of peripheral tryptophan and other large neutral amino acids at 3 and 6 months [ Time Frame: Baseline / 3 months / 6 months ]
    The amino acid tryptophan (TRP) as well as other large neutral amino acids (LNAA) including leucine, isoleucine, valine, and tyrosine will be assessed to determine the TRP/LNAA ratio.

  6. Change in baseline episodic learning and memory scores on the California Verbal Learning Test at 3 and 6 months [ Time Frame: Baseline / 3 months / 6 months ]
    Verbal test of word recall.

  7. Change in baseline concentrations of serum tryptophan and kynurenine levels at 3 and 6 months [ Time Frame: Baseline / 3 months / 6 months ]
