Are nutrigenetics and nutrigenomics the same thing?
They are two concepts often used as synonyms to discuss the joint study of food with genomics and other omics sciences and their influence on the different health-disease phenotypes.
The first one, nutrigenetics, studies the different responses to diet depending on each individual’s genotype (type of gene). On the other hand, nutrigenomics studies the molecular mechanisms that explain the different phenotypic responses to diet depending on the particular genotype of each individual. In other words, it analyzes how nutrients influence gene expression.
What is Omics?
“Omics” is a neologism used in molecular biology as a suffix to refer to the study of the whole or the totality of something. Therefore, in a more generic way, we can say that nutrigenomics analyzes the relationship between food and genetics in a more comprehensive way.
Both disciplines are areas of so-called nutritional genomics. Both are part of the conjunction of omics with food and nutrition sciences.
For dozens of years, nutrigenetic and nutrigenomic studies have provided large amounts of information that allow us to approach what we can call precision nutrition. It basically consists of taking into account the particularities of each individual in order to have the healthiest diet possible. Likewise, nutrition can help prevent or treat a pathology: the more personalized the diet and eating habits, the greater the contribution to improvement or recovery.
There are countless foods and types of diet that both disciplines have analyzed, among which the Mediterranean diet is one of the most noteworthy. Although this type of diet has been defined and catalogued in different ways, studies have shown that it can interact with the genome and reduce the risk of certain pathologies in certain types of people.
What does the 24Genetics DNA diet testing include?
In this respect, the 24Genetics DNA diet testing includes genetic predisposition to the effectiveness of the Mediterranean diet, the low-fat diet and the low-carbohydrate diet.
Moreover, individual genetics is not only related to health. But also with aspects such as taste perception, emotional eating, the propensity to snack, the feeling of satiety, etc… All these aspects are also included in the 24Genetics nutritional, genetic test.
DNA diet testing: personalized diets according to your genes
Every human being is different, both in what we see and what we don’t see. Many of the answers are in our genes, and nutrigenetics is the science that studies these differences. We have probably noticed on many occasions that not all of us feel the same way about food, nor does it have the same effect on our bodies. We see, for example, that someone else loses weight when we eat practically the same food. Or, we do the same amount and type of exercise, and we don’t manage to lose weight. Many factors influence our body mass index, but it seems clear that there is a genetic predisposition to obesity. The key lies in genetic variations, and that is why more and more people are having a DNA dietary analysis.
We can consider diet as an environmental factor that affects the nutritional status of an individual. This is reflected in the possibility of contracting different diseases. Nowadays, nutrition and genetics are joining forces and are both integrated into one area of study: nutritional genetics.
So, if you are concerned about losing weight, your genetic information can help you a lot. We can see your predisposition as to what kind of weight loss diet will be most effective. Some genes can show certain tendencies to put on weight, to feel satiated and to crave food. With the DNA diet testing, we can see if you are predisposed to lose weight more easily and see what your genes say about what might be the most effective way to lose weight and feel better than ever.
Our nutrigenetic report has the following sections:
Based on your genetic code, you can see your genetic predisposition to certain foods, and what types of diets are best for you
Vitamins and minerals
We analyse the genes that affect various vitamins and minerals, as well as your metabolism, so you know which foods you should eat more of and which you should eat less of.
Know your predisposition to cholesterol or triglyceride levels. Understand why your body may react differently to some of the major metabolic triggers
Some genes will give us some interesting insights, such as your possible ability to sense certain flavours more intensely or whether you are prone to sweet tooth or snacking. We’ll also look at genes that may influence the effects of caffeine and much more
Your weight and you
We’ll look at the genes that influence the effectiveness of weight control diets. Some genes affect the tendency to put on weight, the difficulty in being satisfied and the desire to eat. The most effective diet is not the same for everyone, and the answer may lie in our genes.
Frequently asked questions
HOW IS THE DNA DIET TESTING DONE?
It’s much simpler than you think. First, you will receive a DNA kit to take a sample of your saliva. Watch the detailed instructions in a simple video by clicking here. Then all you have to do is send the sample back to us. Next, our laboratory will perform the sequencing. That is the process of extracting the genetic data contained in your DNA sample. And finally, we will apply the algorithm developed by 24Genetics to your genetic information to obtain the detailed report that we will send you.
CAN I TAKE THIS TEST IN MY COUNTRY?
Of course, you can. We can send a DNA kit to your residence or workplace. It doesn’t matter where in the world you live. As we have multiple warehouses across the globe, we will ship your order from the closest possible location. This way, we will be fast, efficient and as sustainable as possible.
BASED ON MY TEST RESULTS, SHOULD I MAKE ANY MAJOR CHANGES TO MY DIET ON MY OWN?
You should not make significant changes to your treatments without the validation of a nutritionist, an expert geneticist or your doctor, who will have access to much more of your health history. Our tests analyse a part of the genetic markers in your body, not all of them. So they provide informative, not diagnostic, results. They provide valuable data on genetic predispositions, but many other factors influence your nutrition or well-being. Therefore, our recommendation is to always consult with specialists in nutrition, health or genetics.
ARE MY GENES THE ONLY IMPORTANT THING?
Our genes largely define how we are, but we and our environment also modulate these genetic predispositions to a large extent. For example, lifestyle, sport, diet and many other circumstances influence our organism. Therefore, the associated genes are significant, but they share their influence on your health, well-being and your life in general with many other factors.
ARE ALL DNA DIET TESTING OF THE SAME QUALITY?
There are few biotechnology companies with the capacity to conduct these complex studies. As a result, many of them give very poor conclusions in terms of the number of results. Our test is based on a state-of-the-art genetic analysis. In this, we analyse about 700,000 genetic markers.
WHY SHOULD YOU BUY THIS PHARMACOGENETIC TEST AND NOT ANY OTHER ON THE MARKET?
The main reason is that we are able to offer you more relevant information (you only have to compare us with other competitor tests) and of higher quality. But there are many more reasons; you can see them by clicking here.
WHAT IS THIS TEST BASED ON?
When there is a high level of consensus, the most relevant scientific studies are made public through international institutions and organisations. The complex algorithm developed by 24Genetics incorporates thousands of these genetic studies recognised and accepted by the scientific community worldwide, so our reports have a very high level of quality.
AFTER TAKING THIS TEST, WHAT SPECIFICALLY WILL I RECEIVE?
We will send you a complete and personalized report to the email address you have registered your kit with. In addition, you can request your raw data file at any time, and we will send it to you by email (the raw data file is an electronic file containing your genetic map).
HOW CAN I KEEP MY REPORT UP TO DATE?
When we design a new trait for inclusion in one of our reports, we perform various tests before making it public. But, for your convenience, when this happens, we will contact you to notify you.
CAN ANYONE TAKE A GENETIC TEST?
Anyone, regardless of age, can take our genetic test. You just need to know that if the test is to be performed on a baby or an elderly person, we can send you a special kit that facilitates the collection of the saliva sample. Just let us know when you place your order.
IS A DNA DIET TESTING THE SAME AS A FOOD INTOLERANCE TEST?
No. A DNA diet testing has nothing to do with a food intolerance test. Nor is it the same as a food allergy test. Different tests provide different information. Genetic tests are infinitely more complex and expensive than the tests mentioned above, and the genetic information they provide cannot be obtained in any other way.
HOW MANY CALORIES SHOULD I CONSUME?
A genetic test does not provide this type of information as it depends on many other external factors, habits, diet… (environmental factors). For example, your genetics being what they are, you may be a sedentary person or, on the other hand, a person with a high level of physical activity. As you can imagine, the need for calorie consumption will be very different in both cases. It will also depend on your dietary goals: you may want to lose weight, or you may want to gain weight. Therefore, the best thing to do with your nutrigenetics test is to share it with a dietetic or nutrition service. They can design personalized guidelines for you that you can implement in your diet according to your goals.
WHAT DIET SHOULD I FOLLOW?
24Genetics does not give advice on dietary habits. We provide you with information about your propensities in our nutrigenetic report. But it should be a professional nutritionist who advises you on the most suitable diet for you. Taking into account, in addition to the genetic information in our report, your lifestyle, your tastes, your sports habits, etc… Therefore, we recommend you share your analysis with your professional reference to carry out a personalized diet.
WHAT FOODS CAN I EAT?
The 24Genetics test does not give information about specific food intolerances. Therefore, if you suspect a particular intolerance or allergy, we recommend consulting a health professional.
CAN I BE DIAGNOSED WITH ANY NUTRITIONAL ALTERATION WITH THIS TEST?
The 24Genetics nutrigenetics test is not valid for clinical or diagnostic use. However, if your health professionals observe any relevant pathology in our reports, they will prescribe a second test with clinical validity to confirm the pathology.
WHAT IS NUTRIGENETICS?
It is the discipline that analyses the genetic variants that you store in your DNA and directly impacts the way you metabolise various molecules. As well as how different diets work or don’t work for you. The best way to nourish yourself and improve your quality of life is to know your genetic tendencies to cholesterol, triglycerides, overweight, etc. Data such as the absorption of vitamins B12 or E are other traits that will appear in your report. For more details, check the example report available on this page of our website.
IS NUTRIGENETICS A FAD, OR IS THERE ROBUST SCIENTIFIC SUPPORT BEHIND IT?
It is an area of knowledge that has been studied for several decades. Genetics interacts with our diet, so the analysis of our human genome is fundamental. It is a fact hundreds of scientific studies now support that. These studies are carefully examined under strict scientific quality criteria within 24Genetics to select the most scientifically relevant ones. In addition, our multidisciplinary scientific team is constantly updating our report, including pertinent new studies that allow us to get the most out of your DNA.
WHY DOES MY REPORT SAY I HAVE AN IRON DEFICIENCY WHEN I HAVE NORMAL BLOOD LEVELS?
The reason is quite simple: genetics is not everything. It is an important factor to consider, but it is not the only determinant. In this particular example, if you have an iron-rich diet, your blood results may be normal, as the genetic predisposition to iron deficiency is probably being compensated for by your diet.
