The fields of nutrigenetics and nutrigenomics are focused on the relationship between human genes and nutrition.
Nutrigenomics investigates how certain foods interact with our genes to affect our health. It is the area of nutrition in which molecular tools such as DNA tests are used to understand individuals diet responses.
DNA Health Testing for Nutrigenetics aims to identify genetic susceptibility to diseases and the ways in which very small difference in our genes can alter the effects that nutrient intake has on the body.
In layman’s terms:
- Nutrigenetics examines how your body responds to nutrients based on your genetics.
- Nutrigenomics studies how nutrients affect your body’s expression of your genes.
Utilize your DNA to take the guesswork out of achieving your goals.
Anxiety concerns? Want to lose weight?
Utilize your DNA to take the guesswork out of achieving your goals.
First, a few simple definitions: DNA, Genetics, and Nutrition.
- DNA is short for Deoxyribonucleic Acid. DNA stores information and instructions for all organisms to grow, develop, function, and reproduce. Human DNA has around 3 billion chemical bases.
- The arrangement of these bases determines every aspect of human function.
- Genetics is the study of how DNA is passed on to offspring (heredity), how and why variations occur, and how these variations are expressed.
- Nutrition refers to both the process of being nourished by food and the study of how nutrients are used in human metabolism, growth, and repair cycles.
- What Are nutrigenetics and nutrigenomics?
The Human Genome Project was launched in 1990 with the goal of identifying and mapping out every single gene in the human genetic code. When the human genome was completed in 2003, entire fields of scientific study opened up.
Nutrigenetics and nutrigenomics are just two of the fields to benefit, and to date, thousands of studies have already been performed and published on these topics.
How Nutrigenomics Impacts Your Diet
Nutrigenomics research takes a general look at how many nutrients or calories an average person should consume and how certain supplements can affect you. There are individual differences in people’s intake of their diets.
This explains why certain people are comfortable in eating a high-fat diet and have no problems with their cholesterol levels. In some people, it is entirely different because they have to watch what they eat and take in. If they don’t, their health might take a hit.
It is recommended that people find the nutrients that can work for them most effectively. This will help determine the specifically required nutrients by their bodies and find out what works for each genetic type.
If researched thoroughly, it has potential in helping treat and prevents all kinds of diseases through nutrition. It might take this discovery for a long time to be realized as a cure to health problems. This is because there is a lot of information that will take scientists a long time to determine if indeed genes do affect nutrition.
It is important if the discussion is extended deeply to nutritionists and general practitioners so that the idea can continuously be researched and a solution can be found.
Obesity, for instance, is widely researched in the study. The dietary changes show how obesity could reduce and be prevented.
Nutrigenomics at a whole looks and evaluates how what we eat affects our genes as well as our overall health. It has the potential to cure diseases and also prevent them through nutrition. When this is discovered as a solution, there will no longer be diet recommendations where people of different shapes and sizes are recommended to one type of solution.
People will have diets that work for them and their bodies without generalizing. It is a work in progress, and many things are being put into perspective about the study of genes and nutrition. Until then, we will have to wait for research to take its full course and eventually help people on their journey to good health.
Nutrigenetics, on the other hand, looks at the relationships in genes and diets and how the health of an individual is affected. It is the foundation of nutrition that is personalized and made to fit the person’s vitamin and calorie intake.
People respond differently to specific diets, and that’s why personalized diets will work and meet an individual’s needs. Nutrition that is personalized is based on how nutrition is integrated into a person’s life, and patients with chronic diseases are genotyped and given ways and strategies on how to reduce their risks and become healthier based on their genes and diet.
It is known through research that our genetic composition influences the outcome of our health in response to the environment and our lifestyle. Personalized nutrition is a new way to keep our health in check. It is also cost-effective since genetics are linked to diets and diseases to formulate a cure.
Nutrigenomics and Nutrigenetics are exploring the interaction between individual genes and the nutrients they deserve to sustain the body functions. If an individual wants to eat healthily, work out and be fit, the person should know about the nutrients and how it helps their body achieve their goal for healthy living.
There is genetic analysis being worked on to find out what food affects you differently and why some flavors make you allergic or taste differently. If a person wishes to live a healthy lifestyle, then genetic information will help them into their journey of disease-free life.
This is because their genetic information highlights how they gain weight and what foods heighten their desire to eat more etc. It gives an overview of the foods not to be taken and what will help you lose weight and get back into shape. All humans are said to be 99.9% identical in regards to their genetic makeup.
The possibility of giving the same dietary plans to two individuals is a possibility. But what is right for one person does not necessarily mean that it is good for another. Genetics in its own does not determine your health and well-being, but it helps determine your diet and nutrient intake.
A nutrition specialist can help with dietary needs by educating you on whether certain diets work for you or not. They understand and test your genes and draw up a conclusion on your food intake and how it has affected your daily routine. They also give you advice based on your diet chart and how you should take better care of yourself to escape chronic diseases.
What is the Difference Between Inherited and Acquired Genetics?
Inherited genetics refers to the traits we inherit from our ancestors. These include height, eye color, skin pigmentation, ect… Inherited traits can also include a number of different health conditions.
We now know that a family history of breast cancer can mean that you are more likely to develop breast cancer.
However, if you carry certain genetic markers in your DNA, then you are significantly more likely to develop breast cancer regardless of your family history.
Acquired genetics are traits that cannot be inherited from previous generations, but they can be passed on to future generations if the reproductive genes are affected. These usually come about from a variety of environmental influences such as exposure to smoke, radiation, chemicals, and of course from certain nutritional factors.
What Can Nutrigenetics Tell You?
The overall goal of nutrigenetics is to be able to develop an individual nutrition plan to help you achieve and maintain your best health possible. When applied correctly, information related to nutrigenetics and nutrigenomics can even help prevent, treat, or even cure certain diseases.
Most thorough diet and nutrition plans begin by calculating the daily caloric needs of an individual and applying the RDA (recommended daily allowances) of important nutrients to the diet plan through foods and supplements. While this approach is better than most, there is an inherent flaw that nutrigenetics and nutrigenomics account for: individual needs and response.
RDAs were developed to be applied to the general population as a whole. They don’t take into account the specific needs or responses of genetic subgroups. The importance of inherited and acquired genetic response in optimizing one’s health cannot be overemphasized.
Your genes can determine how sensitive you are to salt, if you are lactose intolerant, how likely you are to become vitamin D deficient, how well you tolerate caffeine, and even how efficient your body is at repairing injuries.
Nutrigenetics can explain why two individuals of similar age, stature, and activity levels will react differently to the same diet. Should you be consuming more or less saturated fat? Will a low-carb diet actually benefit you? What supplements should you be taking? Which supplements do you need to function properly? These are all questions that the information hidden in your DNA can help to solve.
If good health is what you seek, it is imperative that you take a DNA test. This is to help you discover more about your genes and nutrition. It helps in managing of weight and avoidance of chronic diseases. Most tests are taken with cotton swabs and tested.
Have a test taken and this will help you to be aware of certain foods that are good for you and those that alleviate sickness. It also helps in having a personalized nutritional chart that goes with your daily routine. The DNA can be done, but it’s scientific research that is continuously being improved as research extends.
