America researchers completed the human genome project, finding around 20,000 genes for the human species. However, did you know that our bodies “house” somewhere between 2 million and 20 million microbial genes in our intestines? That is about 2-3 pounds of weight. And those genes are as important for our health as our own genes.
Those genes reflect the diversity of the food that we have eaten; and the greater the diversity, the higher the number of microbial genes. For Americans, that insight gives us incentive to eat a wider variety of foods, not just the standard American diet. If can expand our diet, we can improve our health. How? Listen to this video for an explanation.
