Our nutritional needs are determined by our DNA

Genetic analysis is also widely used to determine diet lists and the extra vitamins and supplements people need. This new field of study, called Nutrigenomics, examines the relationship between genes, nutrition and health. Geneticist and Pharmacologist Dr. Gülay Özgön, Founder of Nesiller Genetik Disease Evaluation Center, answered the questions about Nutrigenomics.

Nutrition, the top basic need of humanity, is regarded among the most important issues globally. The increasing number of undernourished people and the extraordinary rise in obesity rates accelerated scientific studies in this field. Genetic analysis, which is used in the diagnosis and treatment of many diseases, has also taken its place in studies in the field of nutrition. Studies on Nutrigenomics, which examines the relationship between nutritional genomics, the human genome, human nutrition and health, have become widespread worldwide. No healthy life counseling related to nutrigenomics can be given by ignoring the genetic codes.

Our genetic structure is decisive at every step

The science of healthy life, which we call wellness, is based on knowing our own genetic code. The answers to the questions of how we can improve our genetic code and how we can live healthier and longer lives are linked to the results of genetic analysis. No healthy life counseling should be given without analyzing the genetic codes of individuals. At this point, 'personalized medicine' continues to break our memories.

800 million people struggle with obesity

According to the data of World Health Organization, approximately 800 million people worldwide are struggling with obesity. It is estimated that one out of five people worldwide will become obese by 2025. More importantly, the number of children struggling with obesity is expected to increase by 60 percent in the next 10 years and reach 250 million. It should not be forgotten that obesity is the biggest threat to sustainable life. Success in the fight against obesity is possible with interdisciplinary cooperation. Blood values give specific data about the nutritional needs of people. However, for beyond, a detailed analysis of gene structures is required. In nutrigenomics-based diet plans, genetic structure analyzes are performed, personal nutritional and health needs are determined, and dietary recommendations that help prevent chronic diseases are formed.

How correct is shampoo and vitamin in the same basket?

Demand for OTC (over-the-counter) medicine is growing with hearsay about vitamins and supplements. In the stores where we meet our cosmetic needs, we find ourselves putting acetone, shampoo and Omega 3 into the same basket. However, the vitamins and supplements that people need are pluses to be built on the existing DNA structure, and this decision cannot be given by heart. The vitamin supplement market is expanding, and health problems are increasing with the severity of a new pandemic. It's clear that everyone has a different code, and diet plans may not be the same for everyone.
