Advanced Genetic Testing for Nutrition – FAM

Have you ever wondered why some of the people just can eat a lot of specific food and simply not gain weight. On the other hand, others might put on pounds just by looking at it?  

Why a diet that works for your friend might not work in similar manner for you? The answer just lies in your genes. Our DNA, that is the unique blueprint shall all make us as who we are. This shall play a surprising role in how the bodies shall process food and nutrients too. Such field of study, like nutrigenomics, is known to change the way we think about diet and health. 

Nutrigenomics like condition is a branch of science which shall all look at the relationship that is between the genes you hold and the food that is consumed. It is not just about what is eaten; but it is about how the body uses what is eaten. The genes that we hold contain lot of instructions for building proteins.  

This is where the workhorses of our cells go. Some of these proteins shall include enzymes that can break down food, receptors with sense nutrients, and transporters that shall move them around. Getting into a tiny change, or polymorphism, with reference to gene can simply alter as how a protein shall work. This shall affect everything right from that metabolism to your risk for certain health conditions.  

Imagine the body as some car where your DNA is the owner’s manual. While some of the most common cars are similar, each one might have little differences in how it might run. For example, some of the cars shall run better on certain type of fuel. In similar way, the genes are influence as how the body shall handle various foods. A genetic test like help can be just like that mechanic that keeps on checking manual to see what kind of “fuel” is best for you. 

A genetic test like help by LifeCode specifically for nutrition is simple and non-invasive. You might further provide a saliva sample or some cheek swab. This is then sent to a reputed lab. Scientists in the lab shall further extract those DNA and one might look at specific genes for knowing to be related to diet and health. They are further looking for those small genetic differences, or polymorphisms. This can affect how the body responds to food.  

For example, those common gene studied in this field is the MTHFR gene. As stated on Wikipedia, the MTHFR gene “provides several instructions for making an enzyme known methylenetetrahydrofolate reductase.” Such enzyme is mostly crucial for processing folate, which is known as a B vitamin. Some people might have a variant of such gene which can make the enzyme less effective. This can all mean it need more folate from the diet or right from those supplements to simply avoid potential health condition.  

Another well-known example is known to be LCT gene. This is all linked to lactose tolerance. Lactose like condition is the that is found in milk for sure. Most of the people who can digest lactose as infants, but as they shall grow up, many might lose the ability to simply produce that lactase enzyme that is needed to break it down.  

However, some of the people might have a genetic variant that might keep the lactase gene “on” throughout their lives. This can all allow them to digest milk without any issue. This is a clear case where that simple gene variation might dictate a dietary difference. 

Genetic testing with respect to the sector of nutrition is known to offer some of the personalized insights. This goes well into those various aspects of health and diet, including the below. 

  • Weight and Metabolism: Have you ever felt like you are fighting an uphill battle with the weight you hold? The genes shall all play a significant role in this. They can all influence as how the body stores fat, how many calories are burnt each day, and even how hungry you might feel. Further on understanding the genetic predispositions, you can tailor your diet and exercise plan to work with your body, not against it. 
  • Micronutrient Absorption: We do not process vitamins and minerals all under similar ways. The genes can all affect as how efficiently you might absorb and use those key nutrients like Vitamin D, B vitamins (like folate), and omega-3 fatty acids. When the genes might all indicate you having a harder time on absorbing some nutrient, you shall also know how one can adjust the diet or consider supplements and meet the body’s needs. 
  • Food Sensitivities: While some of the help like genetic testing just cannot diagnose allergies, it can further shed light on why this food shall make one feel uncomfortable. For example, while having a variant of the LCT gene, it might be the reason of you experiencing bloating or gas like condition post intake of milk. This knowledge can all help in making some smarter food choices which shall align with body’s natural preferences. 
  • Exercise Response: The DNA can further reveal a lot about that ideal workout routine. Some of the people are usually built for endurance activities, including running marathons, while others shall get better outcome from lifting weights or strength training. On knowing what the body shall respond to best one can help in building a fitness plan that is effective and rewarding at the same time. 

It is all important to approach some those genetic testing like help with a balanced perspective. While it can also offer some powerful insights, it is not a magic bullet. The health is well shaped by both the genes and environment. This shall include the food that is consumed, our lifestyle, and our surroundings. This is usually described as the “nature vs. nurture” debate.  

As a Wikipedia article on epigenetics explains, “Epigenetics is the study of heritable alterations in gene expression. It does not involve changes to the underlying DNA sequence.” This also means that the environment, like diet, can turn those genes on or off. For example, a healthy diet can simply promote the expression of genes which shall protect you from disease, while some sort of poor diet can do the quite well opposite.  

This is why genetic testing like help is not about informing what exactly one must eat. Instead, it helps in providing a roadmap for some of the personalized and effective diet. Think of it as some guide, and not any rulebook. This can all help in understanding the body’s tendencies so that one can make several smarter choices. For example, while your genetic test might show a predisposition to a some of the health condition, you can proactively Alter the diet to lower the risk. 

So, you have received your genetic test results from LifeCode. What’s next? The key is to use such information is to simply create a diet and lifestyle plan which is well tailored just for you. Below are some of the steps to same: 

  1. Understand the Report: Read all the report well. Make sure that you look for clear and some well actionable insights. For example, does it suggest you are a “fast metabolizer” of on some caffeine? This might further explain as to why one might feel jittery post consumption of one cup of coffee. Does it also indicate a higher need for Vitamin B12? It shall also prompt in eating more foods rich in such vitamin, like meat, fish, and dairy. 
  1. Consult a Professional: The best way for using the genetic information is to simply work with a registered dietitian or a nutritionist who shall all understand nutrigenomics. It can also help in translating the outcomes into a practical eating plan. It shall further consider not only those genes but also some of the current health, lifestyle, and food preferences. 
  1. Make Small, Smart Alterations: You do not need to completely overhaul the life you live in. You need to start with small, manageable alterations which is based on the genetic insights. While some of your report shall also suggests you might be better off with a lower-carb diet. You need to try and reducing consumption of those refined carbs and see how one shall feel. While finding to have a predisposition to higher cholesterol, you can further work on enhancing the consumption of foods that helps in lower the case. 
  1. Listen to Your Body: Your genetic report is known to be a tool, but not a strict set of instructions. You need to Pay attention to how different foods shall make you feel. Do can further feel more energetic when you follow these recommendations? Are you seeing some of the positive alterations in the health metrics? The body’s feedback is known to be most important part of such equation. 

The field of nutrigenomics is still believed to be young, but it is growing at a rapid pace. As our understanding of the human genome expands. Hence, while having the ability to create some truly personalized health plans. The idea of a one-size-fits-all diet is a thing that is of the past.  

Genetic testing like help by LifeCode is empowering people to take control of their health by providing them with a deeper understanding of unique biology. It moves us away from guesswork while running towards a more informed, proactive approach to nutrition. By using those DNA as a guide, you can further unlock a healthier, happier you.
