Poor Diet Changes DNA, Causes Lasting Damage to Immune System

The way we interact with the world changes our DNA, not just the other way around. More intriguing, one of the major ways we can change our DNA is by diet. For example, a study published in 2008 showed that exposing mice brains to as little as 6 hours of high blood sugar led to epigenetic changes that increased risk of vascular damage. These changes lasted even after 6 days of normal blood glucose, representing long-term damage after just a short blast of sugar. The research on long-term effects from short exposures is at the core of epigenetics. It’s furthered by data from another 2008 study published in the journal Diabetes.
