It isn't that 'you are what your body does with what you eat' is wrong, its just that 'you are what you eat' is right also!
Nature magazine reports that plant RNAs are found in mammals - which may help '...to increase the understanding of how specific ingredients in food can mediate health and disease':
- MicroRNAs from common plant crops such as rice and cabbage can be found in the blood and tissues of humans and other plant-eating mammals, according to a study published today in Cell Research. One microRNA in particular, MIR168a, which is highly enriched in rice, was found to inhibit a protein that helps removes low-density lipoprotein (LDL) from the blood, suggesting that microRNAs can influence gene expression across kingdoms.
“This is a very exciting piece of work that suggests that the food we eat may directly regulate gene expression in our bodies,” said Clay Marsh, Director of the Center for Personalized Health Care at the Ohio State University College of Medicine who researches microRNA expression in human blood but who was not involved in the study.
Maybe the vegetarians have it wrong and we should follow Vilhjalmur Stefansson's dietary example!
