Nutrigenomics - how it can help you choose the right foods for you
You are a unique person with unique needs especially when it comes to food and diet. A diet that someone else swears by may not work for you (or vice versa). But yet, you see so many “blanket” recommendations on what to eat or which supplements to take and you wonder how much that really applies directly to you. Unlike others, you may be able to enjoy coffee in the evening without any major sleep issues, but have a terrible reaction to gluten (a protein in wheat). Or perhaps, you may need more folate (vitamin B9) than others, but [luckily] sodium doesn’t affect your blood pressure as much.
So why is this? There are genes—and variations of these genes—that can explain why you are unique. And now with recent scientific and technological advances, there is a smarter way to know what nutrition and lifestyle strategies you need to thrive, rather than the old method of following recommendations for the “average person” and seeing how it goes for you as an individual. This opportunity for personalised (or “precision”) nutrition is based on the rapidly expanding field of research that specifically looks for some of your unique needs in your own DNA.
Imagine what you could do with the insight to know which diet, food, or nutrients you should focus on and which won’t likely make any difference to you anyway.
We are talking about the science of nutrigenomics. It’s the combination of nutrition and genomics and helps you choose the foods and nutrients you need more of, based on your unique genetic blueprint.
Nutrigenomics is a rapidly advancing science that looks at the links between nutrition (the foods and nutrients needed to be healthy) and genomics (how the DNA encoded in your genes acts in your body). It’s a form of personalised nutrition that looks at how your personal set of genes influence the nutrients you need. Nutrigenomics is a very high-tech way of tailoring nutrition recommendations to one single person, based on their unique set of genes.
What is nutrigenomics? How does it answer the question "What food should I eat?"
Here’s how your genes work. You have a set of genes that you inherited from your parents (half from each parent). This is your unique “genetic code.” Siblings (except for identical twins) from the same parents have some similarities, but each are still genetically unique individuals. You may have different hair or eye colours, or be a different height from your siblings. All of these uniquenesses are due to your genes.
Each gene is a piece of DNA that codes for one single protein. That’s why you have thousands of genes—because your body needs thousands of proteins to do all of its cellular and molecular jobs to keep you alive and healthy. There are several variations for each gene. For example, you may be genetically predisposed to having high (or low) levels of cholesterol or a resistance (or easier ability) to losing weight. Perhaps you have a lower (or higher) ability to use folate (vitamin B9), but maybe you are (or aren’t) very sensitive to caffeine or high levels of sodium. And possibly, you are very unlikely (or likely) to develop celiac disease.
But how would you know?
By having an accurate genetic test done to look for variations in all of those (and more) genes.
But, it doesn’t stop there. Your genes code for so many areas of health, like metabolism, inflammation, hormones, stress response, moods, detoxification, weight, fitness, cognition, and your ability to use essential nutrients from foods and supplements.
Imagine how you could tailor your food and lifestyle choices if you knew the areas that you as a unique individual should focus on, and which areas you need not worry too much about.
How can nutrigenomics help improve my health?
Let’s go through these examples so you can see what you can do when you learn your unique gene profile and take advantage of precision nutrition.
Resistance to losing weight
Imagine knowing if your genes are influencing your ability to lose weight. Some of our reports will show if you are able to utilise fat, or glucose properly – helping you in your weight loss journey.
High cholesterol levels
High levels of cholesterol can increase your risk for heart disease and stroke. This is partly the result of how your genes allow your body to process fats. If you knew you had genetic variants that made you prone to high levels of cholesterol, you could focus your foods on choosing more plant-based meals, heart-healthy fats, and higher-fibre foods.
Not very sensitive to caffeine
Some people are able to metabolise (process and eliminate) caffeine faster than others. If you know that you are a “fast caffeine metaboliser,” you may be able to enjoy caffeine without having to worry too much about some of the common side effects that happen more often in people who are “slow caffeine metabolisers.”
Lower ability to use folate (vitamin B9)
Folate is found in green leafy vegetables and beans. Supplementation is often recommended for people who are or can become pregnant. If your genes code for a lower ability to use folate, then you may need to eat more folate-rich foods or take a supplement to ensure you get enough folate to compensate for your lower ability to use it so that you could maintain good health.
And remember, these are just a few examples of how the variations in your genetic blueprint can impact your health and wellness, and how you can proactively address them to reach your health goals.
Nutrigenomic testing is very accessible now. It’s never been easier to answer the question, “Based on my genes, what should I eat to optimise my health?”
Take a look at some of our sample Nutrigenomic Reports
This Metabolic report explains how nutrients are absorbed and metabolised and in particular focuses on 6 main personalised pathways to help you determine which foods you need and why..
Appetite Regulation , Nutrient Sensing, Sugar Metabolism
Fat Metabolism, Cholesterol & Bile, Mitochondria & Inflammation
The focus of this report is mainly steroid hormones, plus adrenaline, insulin and melatonin. Symptoms of steroid hormone imbalancess can present as fertility issues, PCOS, endometriosis, menstrual ireegularities, excess facial hair (women), breast tissue (men). osteoporosis plus many more.
A detailed look into 3 personalised pathways
Steroid hormones, Oestrogen lifecycle, HPA and HPG Axis
Methylation is needed for every function in the body and is one of the KEY reports. It is essential for detoxification, immune function, DNA integrity, gene expression, energy, neurotransmitter balance, inflammtion control and protection in ageing.
An indepth report covering the folate cycle, Methionine cycle, Transsulphuration pathway. BH4/Neurotransmiter metabolism, UREA cycle.
Poor detoxification can affect many of our systems which could contribute to gastro-intestinal problems (bloating, constipation, intolerance to fatty foods) immune problems (food allergies, skin rashes, asthma) Hormone dysfunction (headaches, dementia, weight gain), Musculo-skeletal issues (muscle aches, arthritis) plus more…
This report will detail your personalised 5 pathways covering alcohol, mould, Non-steroid anti-inflammatory drugs (NSAIDs), Paracetomol, and Polycyclic aromatic hydrocarbons (PAHs)
Neurotransmitter imbalances can affect our physical and mental health. Symptoms of neurotransmitter imbalance may be mood disordersm attention deficitm obsessive compulsive disorders, addictive behaviours and emotions such as anger, & restlessness.
This report highlights your individualised pathways examining the genes, nutrients and lifestyle factors affecting the nervous system.
Thyroid dysfunction can contribute to many symptoms – hypothyroidism (under active thyroid), weight gain, fatigue, low libido, dry skin, cold intolerance, constipation, depression. Hyperthyroidism (over active) symptoms may be anxiety, heat intolerance, heart palpitations, & weight loss.
This report will analyse your personalised genes in the thyroid hormone cycle – looking at the central thyroid, transport and metabolism and the processing of cofactors (Vit D & A) along with the stressors and toxins.
Histamine intolerance is often mistaken for food allergies or gastrointestinal disorders. Histamine has many important functions protecting us against infectionm regulating our gut physiological functions and it acts as a neurotransmitter.
Symptoms arising from impaired histamine degradation can mimic allergic reactions and affect our skin (itchiness, rash, excema), gastro-intestinal tract (stomach acid reflux, diahorrea, nausea) respiratory (runny nose, asthma, nasal congestion) Vascular (low blood pressure, dizziness, fainting, migraines) and neurological (insomnia, anxiety, memory, ADHD)
Final thoughts and answer to your "What foods should I eat"? question
