Theory of diets according to origin

It seems to me that there could be a case for each person having a diet that is right for their body based on where it's genetic roots are. For example, if your great great great Grandparents on both sides of your family came from Germany, you might live better on a diet of red meat and fruit and root vegetables. But if your great great great Garandparent came from some parts of asia, you would thrive on rice and fish and bamboo(say). Now, going as far as your great great great grandparents is actually a shallow look at the matter as I believe the line should go back 50,000 years or so. How you determine what those ancestors dined on seems to me to be a matter of trial and error.

I seem to thrive on lamb/mutton and green vegetables. Rice is not assimilable, while fish is. Soy of all types is very bad on the digestion. So would that indicate that way back when, my ancestors were sheep herders with vegetable gardens near the village with fish picked up from passing traders? Seems more likely than he theory that they were rice paddy farmers.

So where does this take us? To a lot of experimentation. And to research. What were the diets bck then? What is the equivalent now?

There isthe book "the Origin Diet" by Elizabeth Somer who indicates I am on the right path from what she writes. I hae read half the book so far which makes me a total expert I am sure. But wha she says makes sense for a body that originates from Europe. I also seem to recall there was a book written aboutthe Black African Diet. So it seems there is a ray of truthhere to say the least.

Ponder on it. See if it works for you.

Also ponder on this. If what I say is true, then what place does sugar, potato, rice and Soy have in my diet? Honey as a sweetener makes sense, apples too, but not banana's or wheat!

Hm! How about that!
