Question

Find information on a subject related to one of the three subdisciplines of Nutritional Genomics. Nutrigenetics Nutrigenomics Nutritional Epigenetics Prepare a 1 to 2 page paper, with in-text citations and references at the end. Paper should cover, what subdiscipline is being covered by your example, what is being affected physiologically, and how nutrition influences the outcome.

Answer 1

#. Nutrional genomics - is the field of study that describes the application of genetic technology to food and nutrition

-includes nutrigenetics, nutrigenomics, and epigenetics

Nutrigenetics:-

the interaction between an individual's genetic profile with nutrients and other bioactive food substances

Nutrigenomics :-

The study of the mechanisms by nutrients and other bioactive food components interact with the genome to influence gene expression

Epigenetics :-

diet informed modification of DNA methylation and histone acetylation that alters gene expression

1. Nutrigenetics :-

#. Aim :-

- providing considerable mechanistic insight into the cause of disease

- influence of nutrition on metabolic process

- use genetic profile for the earlier detection of disease risk

- personalisation of dietary recommendations provided to individuals

#. Benefits of nutrigenetics :-

- increased focus on a healthy diet and lifestyle

- motivate positive behavior change

- increased awareness of risk of certain conditions

- focus on prevention

- reduced health care cost

- decreased morbidity and premature mortality

Nutritional genomics provides the means to develop molecular biomarkers of early, pivotal changes between health maintenance and disease progression. These genes might then be used as targets to identify nutritional agents capable of modulating their expression.

Good nutrition along with physical activity, and a healthy body weight are essential parts of a person's overall health and well-being. Together, these can help decrease a person's risk of developing serious health conditions, such as high blood pressure, high cholesterol, diabetes, heart disease, stroke, and cancer, fast recovery from illness and ongoing good health .
