  1. a CI= Confidence interval- selected because of data being stratified; b 99 = 99% and 100 = 100% of people consumed from the cereal group
  2. [A]; [B] and [C]: different symbols indicate which mean DDS values (comparing the four ethnic groups) are significantly different,
  3. Bonferroni multiple comparison test, p < 0.05
  4. **Significant relationship between ethnic groups and whether or not subjects consume food from a specific group, Chi-square test, p < 0.01.
  5. ***Significant relationship between ethnic groups and whether or not subjects consume food from a specific group, Chi-square test, p < 0.0001.
