Imagine if you knew from a DNA test what diseases you were predisposed to. And imagine if you could then find out which foods to eat – or avoid eating – to influence whether or not you might develop those conditions.

This is the fascinating premise behind the science of nutrigenomics: the study of the interplay between food and genes. How do different foods impact our genome? And how might this interaction change our biology to promote health, or conversely, disease?

It may sound far-fetched to imagine we might one day be given a "prescription" of foods to eat.
