Unlock Your Genetic Blueprint: The Power of Nutrigenomics and DNA-Based Diets
Have you ever followed a diet that worked wonders for someone else, only to feel tired, hungry or stuck? There’s a clear reason for that: there’s no one-size-fits-all approach to health. Your body is unique, and the answers to many of your health challenges are written into your DNA.
At Melanie Flood Nutrition, we use the science of nutrigenomics and DNA-based diets to help clients uncover the root causes of symptoms and create a truly personalised path to better health.
What Is Nutrigenomics?
Nutrigenomics is the study of how your genes interact with food, nutrients and lifestyle factors. In simple terms, it looks at how what you eat can switch certain genes on or off, influencing everything from energy levels and digestion to hormone balance and disease risk.
Unlike generic nutrition advice, nutrigenomics recognises that your body processes nutrients differently based on your genetic makeup. Two people can eat the same foods, take the same supplements, and live similar lifestyles, yet experience completely different results.
Why DNA-Based Diets Are Revolutionary
Instead of trial and error, genetic testing provides clear insights into how your body works, including:
How well you absorb and utilise key nutrients
How efficiently your body detoxifies hormones and toxins
Your natural tendency towards inflammation or oxidative stress
How your metabolism responds to fats, carbohydrates, and protein
How your nervous system handles stress
This information allows us to tailor recommendations to your unique needs. That includes nutrition, supplements and lifestyle tips specifically for you.
At Melanie Flood Nutrition, we only test genes that can be positively influenced through diet, supplementation and lifestyle medicine. That’s what makes genetic testing empowering rather than overwhelming. We will also explain the results clearly and in detail, ensuring that you benefit fully from the testing.
Common Health Issues Your DNA Can Explain
Many clients come to Melanie Flood Nutrition feeling frustrated after years of unexplained symptoms. Genetic testing can help uncover why you may be experiencing:
Persistent weight gain or constant hunger
Digestive issues such as IBS, bloating, or constipation
Low energy, fatigue, or anaemia
Anxiety, low mood, or difficulty coping with stress
Hormonal imbalances, heavy periods, PMT, or fertility challenges
Poor sleep or waking regularly in the night
Skin issues like acne, eczema, or psoriasis
Frequent infections or weak immunity
By understanding your genetic blueprint, we can target the root cause rather than simply managing symptoms. The results? A healthier you in the new year, and a brighter future.
The Role of Methylation in Your Health
One of the most important processes influenced by your genes is methylation. Methylation affects energy production, mood, detoxification, hormone balance, and even how well your body repairs DNA.
Variations in genes such as MTHFR, COMT, MTR and MTRR can slow down methylation, increasing your need for specific nutrients and lifestyle support. This is why some people feel worse when taking standard supplements or following popular health trends.
Melanie Flood Nutrition offers the MethylGen test, one of the most comprehensive methylation tests available in the UK and worldwide. Made famous by Gary Brecka, this test provides actionable insights that can dramatically improve energy, mood, and overall wellbeing when addressed correctly.
