The study of how nutrients affect the expression of a person's genome is known as Nutrigenomics.

Explanation

Nutrigenomics is a field that explores the interactions between nutrients and genes, including how the environment and diet influence gene expression and how genetic variations affect individual responses to nutrients. This branch of study aims to understand the relationship between diet, genetics, and health, ultimately paving the way for personalized nutrition approaches tailored to an individual's genetic makeup.

On the other hand, the term Nutrigenetics refers to how genetic variations affect individual responses to dietary components but does not specifically focus on the impact of nutrients on gene expression, which is the core aspect of nutrigenomics.

Therefore, the correct answer is Nutrigenomics.
