The DNA (genetic, genodiet) diet is sometimes called the most personal diet in the world. Reason? The diet is determined on the basis of DNA tests. It consists in eliminating products that negatively affect the body from the menu. Examination of the genetic material indicates the best diet for the genome of a particular person.
Is there a perfectslimming diet ? And if so, is it agenodiet-DNA diet( genetic )? Some specialists believe that it is. More and more new diets are introduced on the Polish market, prepared on the basis of DNA gene analysis. They are advertised as the next most effective way to get slim. The method of composing a diet based on the genotype came from the United States and is popular among Hollywood stars. Jessica Alba is among the actors who use their genome to prepare a special diet.
Scientists are skeptical about DNA-based diets
We still don't know enough about genes. Genetics is an evolving field. It is believed that soon such areas as nutrigenomics, nutrigenetics and BFY food, or "Better For You", will have a significant impact on consumers' nutritional decisions. For now, however, we should be careful.
"Weight is something that is 10% dictated by our genes and 90% by our lifestyle. Everyone is at risk, some more, some less. Our understanding of the interaction between food and genetics is important. It is possible that in the future, as research develops, we will be able to use this knowledge more effectively "- explains Michael Dansinger from the Tufts School of Medicine (source: Gazeta Prawna).
On the other hand, more and more information about diets based on your genes appears on the web. New websites are being created offering DNA tests and professional reports specifying the nutritional preferences of the tested person and a menu prepared on the basis of the research results. At the beginning, genetic material is collected, specialized tests are performed, and based on the results, a menu appropriate for a given person is prepared.
This is very interesting from an impact perspectivenutrition for general well-being. After the analysis, it may turn out that frequent headaches, general apathy or sadness are caused by an excess or deficiency of one of the nutrients.
What is nutrigenetics and nutrigenomics?
Nutrigenetics deals with the genetic differences between individuals. Its purpose is to answer the question of how biological variability, expressed in genomic differences, affects how a person should eat and how to compose a diet based on the knowledge of a person's genetic preferences. Nutrigenomics identifies the mechanisms that determine how food and nutrition affect a patient's he alth.
What is the obesity gene?
Genes are known to be responsible for eye color, hair structure and life expectancy. Scientists from the UK have gone one step further. They managed to abstract the so-called obesity gene. This discovery is likely to revolutionize the food and dietary market. After comparing the genotypes of several thousand people with type II diabetes to several thousand he althy people, it turned out that people with excessive carcasses have the same variant of the FTO gene.
The obesity gene is otherwise known as the gene responsible for storing fat in cells. This means that fat accumulation can be inhibited at the cellular level.
