I would say that's maybe 1/3 of what we need to know to accomplish your objective. The other thirds are the 100 trillion microbes that make up your microbiome

I would say that's maybe 1/3 of what we need to know to accomplish your objective. The other thirds are the 100 trillion microbes that make up your microbiome (https://en.wikipedia.org/wiki/Microbiota https://en.wikipedia.org/wiki/Microbiota), and the fact that we still don't know hardly anything about the relationship of various foods and how we eat them to health. Especially since different genomes and microbiomes make this particularly difficult for quality research.
