That obsession with "healthy", historical way of living and "unhealthy", modern way is an interesting phenomenon.
We have never lived longer, records in sports are constantly improving *(not counting those boy-like girls from Eastern Germany) and... Just remember how 60-years old people used to look like 30 years ago. I remember them is almost dead. Today, 60 years old people are just fine, active, full of life. They have 25+ years!
Well we're all lifehackers now, trying to find that small thing that might give us an edge. There's wisdom, I think, in how people used to eat. Traditional recipes unwittingly combining ingredients to yield a complete protein (like rice + lentils in Moutzentra) is one example.
A lot more research these days is being done on how foods combine with one another, rather than just on their individual nutrients. Fun stuff!
