This pilot study will evaluate the effects of a placebo anti-inflammatory diet in individuals with spinal cord injury. It is being performed to ensure that the placebo diet does not induce reductions in inflammation and also adequately conceals group allocation.
Anti-inflammatory diet is a novel treatment that may be beneficial for managing chronic inflammation and neuropathic pain (NP) after Spinal Cord Injury (SCI). NP is a common complication following SCI that significantly decreases quality of life. Treatment options are limited, and current treatments can have significant side effects. Those with SCI have identified a need for additional treatment options, particularly those that are not medications. As pain is a subjective outcome, awareness of group allocation could influence treatment expectations and participant rated scores of neuropathic pain. It is therefore important to ensure that an adequate placebo intervention is utilized. This pilot study will assess whether the placebo diet to be used in an upcoming RCT provides sufficient group allocation concealment (i.e. ensure participants are unaware of whether they are on the anti-inflammatory diet or placebo diet). This pilot study will also assess whether the placebo diet is in fact inflammation neutral (ie. induces no reductions in inflammation).

The dietitian will assist in developing a diet that is isocaloric to the anti-inflammatory diet and healthy (for the sake of the participants' well-being, and to blind participants), while allowing many foods that are (counterintuitively) pro-inflammatory (e.g. whole wheat bread, white beans, oats, soy, eggplant, raspberries, pumpkin seeds, popcorn, etc). Occasional "cheat" foods are built into the placebo diet but with more pro-inflammatory options (e.g. two glasses of wine per week).

C-Reactive Protein
Change in plasma C-reactive protein from baseline to post intervention.
Time frame: Baseline and Week-5 (post measures collected following 1-week group allocation period and 4-week intervention)
Diet Compliance
Diet compliance will be assessed following the intervention. Compliance to the specific diet will be assessed by a detailed analysis of all diet records. Each food item will be categorized as either a "food to consume," a "food to avoid," or a "neutral food" based on the parameter of the diet participants who were instructed to follow. Food will also be categorized into servings in accordance with Canada's Food Guide. Therefore, compliance score will be based on standard servings of foods subjects were instructed to eat vs. foods they were instructed to avoid. To account for differences in total energy intake, compliance scores will be expressed as a ratio of the servings of foods to consume over the total servings of food (avoid + consume) multiplied by 100. The percent compliance will then be generated.
Time frame: Week-5 (post measures collected following 1-week group allocation period and 4-week intervention)
