Dietary Data
Description
The Excel sheet 1 provides information on the frequency and the amount of food items consumed, daily intakes of macro and micronutrients, phytochemicals, dietary fibre, servings of food groups (vegetables, fruits, grains, dairy, meat/beans, dairy and fat/sugar/sweets) and health indices (glycaemic index, glycaemic load and healthy eating index). The frequency of consumption of food items is presented as the following codes; 1=never, 2=a few times per year, 3=once per month, 4=2-3 times per month, 5=once per week, 6=2 times per week, 7=3-4times per week, 8=5-6 times per week, 9=every day. To be consistent, we have converted the frequency of consumption of food items to per week. As shown in Excel sheet 1, the amount of food consumed is coded as 1, 2, 3, 4 referring to the serving sizes from small to large and M referring to missing data. Excel sheet 2 provides the codes based on the number of servings from 1-4 or missing data as “M” for each food item or a group of similar items. Excel sheet 3 provides the data dictionary for demographic and lifestyle variables, indicators of EBW, and food items provided in the excel sheet 1.

Steps to reproduce
1) Group the food items consumed by each study participant as pro-inflammatory or anti-inflammatory based on published reports of knowledge about their effects on overall diet-related inflammation score or inflammatory biomarkers 2) Compute the weekly consumption of each food item using the frequency and quantity information reported by the participants. 3) Categorize the consumption of each food item into three groups of consumption level as high, moderate or low based on frequency and amount consumed per week and provide a score depending on whether the item was pro-inflammatory (+2, +1 or 0) or anti-inflammatory (-2, -1 or 0). 4) Add inflammatory scores of all items to create the overall dietary inflammatory score for each study participant.
