Nutrigenomics integrates genomics and nutrition. It is a branch of nutritional genomics and study of effects of foods and food ingredients on gene expression. Its basic goal is to improve health and to prevent diseases through customized diet lifestyle modifications.
Nutrigenomics determines the individual nutritional requirements based on the genetic makeup of the person as well as the association between diet and diseases. It will identify the genes involved in the physiological responses to diet.
What is Nutrigenomics all about?
In the easiest term, nutrigenomics is the study of genetic research on how foods affect our genes and how genetic variations affect the way we react to nutrients in foods.
The human body has 3 billion pairs of DNA living within 23 pairs of chromosomes. Protein coding genes comprise around 2% of your genome. It is the very small part that contains the genes that define your unique characteristics, such as lean muscle, lactose sensitivity, hair type. These genes direct your amino acid arrangements for proteins that create your characteristics.
So despite having the same genes, we all have genetic variants that can influence what we are allergic to, what our bodies need to energize and what we look like. Scientists have discovered that different people respond in different ways to different ways to different diets as the variations in our DNA can have a significant influence on metabolism.
Importance of Nutrigenomics
-Specific dietary profiles can modulate the delicate balance between health and disease acting, either directly or indirectly, on gene expression.
-Personalized diets, which take into account individual genotype, represent the ultimate goal of Nutrigenomics studies, as they can lower risk in genetically predisposed individuals.
-You all aware that one should eat plenty of foods and limit fried items and fats and carbohydrates but with the help of nutrigenomics, you can know which particular food or vegetable is more helpful to you or more harmful to you.
Potential Benefits of Nutrigenomics
- helps in understanding the role genetics play in health and diseases to a greater extent, especially in the case of chronic diseases.
- helps in finding our better medicinal interventions that help you deal well with your existing diseases.
- helps in identifying abnormalities in the earlier stages and also helps in the initiation of strategies to reduce risks timely.
- has helped in shifting the focus from disease management to disease prevention and health promotion.
- It has helped in identifying the molecular mechanisms that are related to the interactions between environmental factors and genes. This also includes the components of food that lead to these interactions.
- helps an individual to make a personal diet plan based on the individual dietary choices based on their particular genotype.
- leads a person to changes in their food choices. They make better choices in selecting the foods that will help them reduce their susceptibility to diet-related diseases.
There are various genetic testing laboratories in the market which provide nutrigenomic test and then they generate detailed gene report as per your test.
