In recent years, science has revolutionised our understanding of the relationship between what we eat and how our bodies work. Beyond calories or macronutrients, a fascinating concept has emerged: the epigenetic diet. But what exactly does this mean and how can it influence our health? In this article we explore what the epigenetic diet is, what it is for and how it helps us live better.
What is the epigenetic diet?
Epigenetics studies how certain factors, such as diet, stress or exercise, can ‘switch on’ or ‘switch off’ genes without changing our DNA. Imagine your DNA as a recipe book: it is not altered, but epigenetics decides which recipes are read and which are ignored. The epigenetic diet, then, is a dietary approach designed to positively influence these genetic switches, using specific nutrients to optimise our health.
Unlike traditional diets that focus on losing weight or gaining muscle, the epigenetic diet seeks a deeper goal: to modulate the expression of our genes to prevent disease, improve our energy and promote long-term wellness. It is based on foods rich in bioactive compounds (such as vitamins, antioxidants and phytochemicals) that interact with our epigenome, the set of chemical markers that regulate genes.
What does it do?
The epigenetic diet has an ambitious purpose: to harness the power of nutrition to influence our biology at the cellular level. Some of its main uses include:
- Disease prevention: Foods such as cruciferous vegetables (broccoli, kale) or antioxidant-rich berries can reduce inflammation and protect against chronic diseases such as cancer, type 2 diabetes or heart problems by silencing genes related to these risks.
- Healthy ageing: Compounds such as resveratrol (in grapes and red wine) or curcumin (in turmeric) are linked to the activation of genes that promote longevity and repair cell damage, helping us to age better.
- Optimising metabolism: An epigenetic diet can improve how our body uses energy, balancing genes related to fat storage or insulin sensitivity.
- Mental health: Nutrients such as omega-3 fatty acids (in oily fish) or folate (in green leafy vegetables) influence genes that regulate mood, reducing the risk of anxiety or depression.
How does it help?
Adopting an epigenetic diet is not just a way of eating, but a tool to take control of our health at a deeper level. Here are some practical benefits:
- Personalisation: We don't all respond the same to food. Epigenetics helps us understand that a diet tailored to our genetic needs (e.g. through DNA testing or lifestyle analysis) can be more effective than a generic one.
- Stress resistance: Foods rich in polyphenols (such as green tea or pure cocoa) strengthen our stress response by influencing genes that regulate the stress hormone cortisol.
- Cell repair: Nutrients such as vitamin D or sulforaphane (in broccoli) support cell regeneration, helping our bodies stay young and functional.
- Hormonal balance: An epigenetic diet can regulate genes linked to hormones such as oestrogen or testosterone, improving everything from fertility to sleep.
How to get started?
You don't need a lab to incorporate epigenetic principles into your diet. Here are some practical tips:
- Eat varied and colourful: Fruits and vegetables of all colours (red from tomatoes, green from spinach, purple from blackberries) provide phytochemicals that act on the epigenome.
- Go natural: Avoid ultra-processed foods and opt for whole foods such as nuts, pulses and whole grains.
- Include superfoods: Add turmeric, ginger, garlic, green tea or oily fish, known for their epigenetic effects.
- Listen to your body: Combine diet with habits such as sleep and movement, as it responds to lifestyle as a whole.
Conclusion
The epigenetic diet reminds us that we are not slaves to our genes: what we eat can shape how they express themselves. It is not a fad, but a science-based approach to living healthier and in harmony with our bodies. While it doesn't promise miracles, it gives us a powerful tool to prevent problems and enhance our well-being. Are you up for trying it? A plate full of colour and nutrients could be the first step to ‘talk’ to your genes in the best way.
