How DNA Is Affected By Today's Diet


We are always told that we are what we eat. Most people believe that this saying applied just to them not to their children or their grandchildren. Recent studies into DNA has uncovered evidence that we are not just what we eat we are what our parents and grandparents ate as well. If that is not enough to unnerve you the same is also true that what we eat now (or have done in the past), is what our children and grandchildren will be. So we have the responsibility to our descendants to help pass on all the heathy aspects that we possibly can through our DNA,

The speculation about DNA and what it can actually pass on has been the focus of scientists for many years. The interest has been brought by the known health factors that can be passed on through genetics such as diabetes and obesity. The area research that has been focussed on looking at the outside forces that alter DNA structure is called Epigenics.

Epigenics does not just look at DNA it looks at the chemicals that may work with the DNA to make changes either through making particular proteins or a completely new type of cell. Research using mice have found that mice that have been fed different diets have produced different offspring. The baby mice have varied in the colour of their fur, weight and possibility of a raised probability of chronic disease all that have been dependent on what the mother was fed on during pregnancy.

This work was then built on by scientists in the Netherlands which hypothetically applied this information to other animals and humans. They are confident that diet changes influence both the sperm cells and the egg cells, which are then passed on to the children. Looking at historical evidence this is nothing new. Children that were born at the end of the Second World War, especially children whose mothers were subjected to the Dutch famine were more susceptible to glucose intolerance and cardio vascular disease. It would be interesting to pick up further evidence in the form of health information about the offspring of those children to see if the health difficulties were still prevalent or had disappeared.

A further study in Poland, speculated that DNA changes or mutations were not always bad, they were capable of good changes as well. At the moment everything is possibilities and is not yet a finite rule.
