Food ratings are based upon scientific evidence. The distance from the neutral line to the food is directly proportional to statistical calculations, specifically the Relative Risk (RR) of Death and/or Disability Adjusted Life Years (DALY). The videos review the evidence that led to these ratings. The Reference Sources page lists studies that have been analyzed. This graphic will only show foods that I have reviewed. After I publish new videos this graphic will be updated with the new food reviews. Over time I will add the statistical Confidence Intervals (CI).
