you are what you eat -- on a genetic level
"You are what you eat" is a well-worn cliche -- but it turns out to be true in a more direct way than most of us ever suspected. 80 beats reports on research showing that micro-RNA (miRNA) from the plants that we eat can enter the bloodstrean and affect the expression of our genes. It's yet another example of how epigenetics is shattering notions of genetic determinism and showing that inheritance is not destiny.
