We have made amazing strides in recent years in understanding the human genome. Many researchers have been surprised to discover that the DNA sequence doesn’t adequately explain why some of us are more susceptible to diseases such as cancer and diabetes. Instead they have found that the nutrition available to our grandparents can have a profound affect on our health and longevity via what are known as epigenetic changes.
Epigenetics translates literally to “upon the genes.” For example, a common epigenetic change is where a chemical compound known to us nerds as a methyl group is added to the DNA. It doesn’t change the basic code but it changes whether that particularly gene is expressed. Many studies have shown that cancer patients have much lower amounts of these methyl groups on their DNA than the average population.
Besides the availability of food, environmental exposures also lead to epigenetic changes. Higher…
