Health and diet and (multi-)multimodal distributions

I knew it! 😁 The Effects of White vs. Whole-wheat Bread May Vary Greatly Between Individuals | Big Think:

...the glycemic response to each type of bread and the way it was metabolized was person-specific and could be predicted solely based on the microbiome makeup of that person, collected prior to the study. The microbiome itself was resilient to the intervention and did not change in individuals as a result of the study.  The findings suggest that making blanket statements about a particular type of diet may not be appropriate and understanding dietary effects requires taking into account person-specific factors.
