Genetics and Genomics covers everything from detailed information about genetic disorders, background on genetic and genomic science, the new science of pharmacogenomics, tools to create your own family health history and a list of online health resources.
Genetic testing uses laboratory methods to look at your genes, which are the DNA instructions you inherit from your mother and your father. Genetic tests may be used to identify increased risks of health problems, to choose treatments, or to assess responses to treatments.
Nutrigenetics aims to identify how genetic variation affects response to nutrients. This information can be applied to optimize health and prevent or treat diseases. The ultimate aim of nutrigenetics is to offer people personalized nutrition based on their genetic makeup
A major goal for nutrigenetic is to identify genes that make certain individuals more susceptible to obesity and obesity-related diseases. The thrifty gene hypothesis is an example of a nutrigenetic factor in obesity. The thrifty gene theoretically causes bearers to store high-calorie foods as body fat, a most likely as an evolved protection against starvation during famines. However, the potential “thrifty genes” that may be affected by nutritional factors have yet to be identified. Future advancements in nutrigenetics research may potentially prove the existence of thrifty genes as well as find counter-effects in order to prevent obesity and obesity-related diseases.
A major goal in nutrigenetics is to allow nutritionists and physicians to individualize health and diet recommendations. Consequently, preventive medicine, diagnostics and therapies could be optimized.
