Epigenetics: How Your Choices Effect Your DNA and The DNA of Your Offspring

Today Mark Sisson had a great post on his blog about Reprogramming Your Genes. The jist of his post was that your genes cannot be altered (sorry you got what your parents gave you) but there is another level to genes called epigenetics that can be. Epigenetics are the top layer of genes controlled by the chemicals your body produces and the chemicals you put in your body. These Epigenes turn your actual genetics on or off controlling how genes produce different cells and reactions in your body.

The main point is that you actually do have control over your genes. The choices that you make effect how your genes express themselves. The following videos are from Nova and detail a study conducted about Epigenetics in human twins.

This is fascinating stuff. Check it out:
