ABSTRACT
The capacity to control gene expression permits cells to supply a specific protein whenever required for everyday survival or function. The activity of a gene leads to the creation of the gene’s protein product. The pattern of proteins produced in one tissue versus another is the easiest way to see how gene expression is controlled. Epigenetics is the study of semi-heritable genetics. Epigenetic processes are major determinants of gene expression activation or repression. The quantity and quality of food consumed have a significant impact on cellular activities at the molecular level. Dietary exposures can have long-term consequences for health. Nutrients have the ability to alter gene expression, controlling metabolic processes. This chapter gives an account of how dietary components affect gene expression, such as the influence of vitamin C, niacin, folate, vitamin B12, vitamin D3, resveratrol, quercetin, fisetin, myricetin, gallic acid, EGCG, soybeans, fava beans, lupin, kudzu, Psoralea, curcumin, and grapes on gene expression.
