What You Eat Affects Your Genes

"Tiny bits of genetic material, called microRNAs, can make their way from the food you eat into your blood stream, and change how your genes are expressed, according to a new study. A team of Chinese scientists found tiny bits of white rice microRNA floating around in people's blood after a meal. When they looked at what was happening on a cellular level, they found that the microRNAs were changing gene expression, decreasing levels of a receptor that filters out LDL (bad) cholesterol. When the scientists gave mice both rice and a chemical to block the microRNAs, their levels of that receptor returned to normal---showing that the microRNAs weren't just swimming through the blood stream, but acting on genes in the animals' cells."
