Nutriepigenomics is the study of ........

Explanation:

There is now considerable evidence that nutritional imbalances during gestation and lactation are linked to non-communicable diseases, such as obesity, cardiovascular disease, diabetes, hypertension, and cancer.
If metabolic disturbances occur during critical time windows of development, the resulting epigenetic alterations can lead to permanent changes in tissue and organ structure or function and predispose individuals to disease.
Epigenetics relates to heritable changes in gene function that occur independently of alterations in primary DNA sequence.
The period of development in which the nutritional imbalance occurs is very important in determining which disease-related genes will be affected.
Different organs have critical developmental stages, and the time point at which they are compromised will predispose individuals to specific diseases.
Epigenetic modifications that occur during development may not be expressed until later in life depending on the function of the gene.
While the majority of studies implicate prenatal and perinatal periods as critical time windows, some research has shown that nutritional intake during adulthood can also affect the epigenome.
