Nutrition Science, ah yes. What would your reaction would be if I told you that we claim that the interaction of seven billion human beings to many thousands of previously living organisms will be the same for each of those human beings? That's obviously nonsense. In other words, you can't just say consuming eggs does X to everyone. You need to partition foodstuff AND partition humans, the partitioning likely based on genetics but also probably other factors as well and then you can describe how each partition reacts. Those other factors likely include previous reaction of food intake... It's a gigantic mess. Until we know a lot more, I will take every nutrition advice as if a dead cat wrote them. https://en.wikipedia.org/wiki/List_of_animals_with_fraudulent_diplomas#Henrietta https://en.wikipedia.org/wiki/List_of_animals_with_fraudulen...
- User23 8y agoIt's almost as if different human populations separated by insurmountable geographic barriers in wildly differing ecological circumstances for myriad millennia underwent selection pressure!
- dsr_ 8y agoAnd have mixed-and-matched enough that claiming any sort of "purity" is idiotic. We're all braided together.
- jdminhbg 8y agoI don't think anyone is claiming "purity" at all. Purity, if anything, would make things simpler.
- feanaro 8y agoThe operating principle is homogeneity. Purity is a bit of a misnomer because a "perfectly" homogeneous species with no distinctive heterogeneous groups would have to be called pure, but that's not usually how people use the word. The implication is usually that there are several distinct, homogeneous groups within which there is homogeneity among its members. Having homogeneity at some level, even if it ends up being in the form of several homogeneous groups, allows one to make useful scientific findings and generalizations. On the other hand, if everything was very heterogeneous, down to each individual, it would be very hard to find a general statement applicable to any appreciable number of individuals.

- feanaro 8y agoFor some phenomena, that might turn out to be true. However, counterexamples are fairly prominent and obvious, e.g. there is a very large subset of humans (~all) for which antibiotics work well for almost all bacterial diseases.
- fromthestart 8y agoI'd venture to guess that the overwhelming majority of the world's population dies quite close to place of birth with very little intermixing.
- esyir 8y agoComing from a biology background, this is the exact sort of catch-all statement I really despise. Is there purity? No, not in the absolute sense. However, we're not some homogeneous mix either. Genetic, environmental and other such patterns do form a number different subgroups which while imperfect, remain useful.
