Everyone is unique when it comes to how their body uses vitamins, minerals, carbs, and protein. The right diet for your friend may not be the one best suited to you.
Let me give you an example of Diet / Gene Interaction:
The American Cancer Society made headlines a couple of years ago by announcing that eating processed meat causes colon cancer. When you dig into the science a little more, though, it turns out that people who carry the risk allele for the GA/TA3 gene (involved in inflammation) are at a higher risk of colon cancer with higher processed meat consumption. Those without the risk allele (60% of Caucasians and 90% of Asians) are not at an increased risk of colon cancer with meat consumption. (Read the whole article)
