the assumption here is perhaps based on a random sampling the population. However eating in a way that has been shown to work for your local population (say your tribe or your family) might be more on your favor? the reasoning in my head being, a similar genetic profile as well as a similar Microbiome profile among the local populations is more likely, and so would bias the chances of following some preconceive notion. But with most of our food choice being influenced by mass advertising and fads spread via television and radio etc... This would be a good rule of thumb.
