FAQ: Interaction Between Food and Genes  Food interacts with
genes? Indeed, research has shown that nutrients comprising
foods affect gene expression, the process through which the DNA
(deoxyribonucleic acid) comprising our genes is converted to RNA
(ribonucleic acid) and proteins are produced.  The various
proteins formed at discrete points in this process function as
enzymes (essential compounds that aid biochemical reactions),
hormones, and other substances on which life depends. Thus, this
interaction can be of considerable significance.  The amount,
form, and even the frequency of nutrients consumed can affect
protein manufacture, resulting in less protein being produced,
less than optimal functional forms of proteins, or no protein at
all. Depending on individual genetic variations and age, these
effects may result in varying individual responses to
environmental factors, such as diet and drugs. The effects can
be overt, such as the effects of vitamin deficiency diseases, or
more subtle and complex, as
