On the one hand, the nutrients we consume can affect the way our genes are expressed; on the other, our genes are able to influence how our bodies respond to these nutrients. Personalised nutrition is looking at the complex interaction between nutrients and genes to create tailored diets which complement a person's unique genetic profile. Not only will personalised nutrition optimise the health of the individual, but it may also work on a larger scale to help prevent society-wide diseases such as obesity, Type 2 diabetes, cardiovascular disease, cancer, and malnutrition.
Many potential benefits are expected from research into genes and how they function. Review current understanding of the structure and function of the human genome.
