In recent years, allowed the identification of genetic variants associated with susceptibility to certain diseases , potentially modifiable through interaction with dietary factors . There are examples of gene-diet interactions in so-called classic metabolic diseases, such as galactosemia, phenylketonuria, congenital hyperhomocysteinemia , etc. In them, the phenotype can be modified with an adequate diet and compatible with the enzymatic activity, which has been damaged by the genetic mutation. For example, low galactose diets, low phenylalanine diets, or diets high in folic acid , respectively.
Based on this model of gene-diet interaction and monogenic diseases, the aim is to extend knowledge to the most complex and prevalent E Commerce Photo Editing diseases, such as cvd, cancer, dementias, dm, obesity, etc. What would it be like in the future? Based on these insights, precision medicine can be practiced that takes into account interindividual differences, such as genetic profile, microbiome, and environmental factors . In relation to food, looking at someone's genome we can know if they have more or less risk of obesity, diabetes, high cholesterol, cancer or neurodegenerative diseases. And what nutrigenomics studies is the interaction of diet and how it can help us minimize, prevent or avoid it . In other words, from a genetic analysis or an observation of the symptoms, a personalized treatment can be made .
The application of precision nutrition takes into account not only the genetic heritage of people, but also their preferences, their perception of taste, the best cooking techniques, the use of spices, the pleasure and enjoyment of food. At higher risk of disease, a complete study of the person becomes more important, in order to use a type of nutrition favorable to their genetics and their vulnerabilities . But for this, still more research is needed , and also to get a better understanding of the genome. Should you do a genetic study? In spain you can carry out a complete genomic study from saliva for around €2,000 , almost half of what it costs in the united states.
