The results of the study point to the fact that ----.
“You are what you eat” says an old proverb. Yet, what if
it were literally true? What if material from our food
actually made its way into the control centres of our
cells, taking charge of fundamental gene expression?
That is in fact what happens, according to a recent
study in China of plant-animal microRNA transfer.
MicroRNAs are short sequences of nucleotides – the
building blocks of genetic material. For the study, blood
samples from 21 volunteers were tested for the
presence of microRNAs from crop plants, such as rice,
wheat, potatoes and cabbage. The results of the study
revealed that the subjects’ bloodstream contained 30
different microRNAs from commonly eaten plants, and it
appears that they alter cell function. For example, a
specific rice microRNA was shown to inhibit the genetic
receptor that controls the removal of cholesterol from
the bloodstream. The suggestion that plant microRNAs
play a role in controlling human physiology highlights
the fact that our bodies are highly integrated
ecosystems. These findings may also illuminate our
understanding of co-evolution, a process in which
genetic changes in one species trigger changes in
another. For example, our ability to digest the lactose in
milk arose after we domesticated cattle. Could the
plants we cultivated have altered us as well?
