Nutrition Theory

I started a nutrition class last week. I think nutrition and how it affects our bodies is very interesting. In my textbook there was a section on Nutrigenomics. The theory is that what we eat, our lifestyle and our environment can alter our own DNA by turning off or on certain genes in certain people. They showed a certain breed of mice that are yellowish color and prone to large fat stores. By changing the diet of the mice, their offspring are born brown (instead of yellow), store less fat, and increase their life span. The theory is certain diets can trigger different reactions in people because of their DNA and somethings are beneficial across the board because of how it effects human DNA.

It will take decades for the researchers to proved weather it's true or not. But, it is interesting food for thought!
