01 Oct This Diet Can Reduce Your Epigenetic Age
Ageing doesn’t have to be just about getting older; it’s about how well our cells age along the way. Recent research shows the food we eat can slow the biological ageing process at a cellular level, giving us a real chance to enjoy longer, healthier lives. This study published in JAMA Network Open found that a nutrient dense, low sugar diet can reduce your epigenetic age. This recent research further highlights the impact of what we eat on the speed at which our body ages.
WHAT IS EPIGENETIC AGE?
Epigenetic age refers to a biological age estimate based on modifications to a person’s DNA in response to environmental factors, including diet, lifestyle, and exposure to toxins. This is different to our chronological age, which is the time that has elapsed since we were born. By analysing DNA methylation patterns, scientists can estimate how “old” a person’s cells are in biological terms. Think of your body’s cells like a car engine. Over time, wear and tear builds up, but this ‘wear’ isn’t just about how many years pass. It’s about how lifestyle and environment affect your cells’ ‘age.’ Scientists measure this as epigenetic age, a powerful glimpse into your true biological clock. Epigenetic age can provide insights into a person’s overall health, ageing process, and potential longevity. Our epigenetic age often correlates with the risk of age-related disease.
NUTRIENT DENSE, LOW SUGAR DIET CAN REDUCE EPIGENETIC AGE
In a study of 342 women in their late 30s, researchers analysed diets and epigenetic age markers. They discovered that a higher intake of essential nutrients and adherence to healthy dietary patterns, like the Mediterranean diet (that’s vegetables, olive oil and quality proteins, rather than pizza and pasta!), correlated with a younger epigenetic age. Conversely, higher added sugar intake was linked to accelerated epigenetic ageing. The Mediterranean diet focuses on fresh vegetables, fruits, whole grains, nuts, legumes, healthy fats like olive oil, moderate fish and poultry, and limited red meat and sweets. It’s less about rigid rules and more about wholesome, balanced meals rich in nutrients.
These associations remained significant even after considering overall diet quality, highlighting the importance of both increasing nutrient dense foods and reducing sugar consumption for cellular health.
While this finding isn’t surprising, it’s yet another piece of evidence linking what we eat to our longevity.
HOW TO EAT TO SLOW YOUR BODY’S AGEING PROCESSES
- Base your diet on nutrient dense, whole foods as much as possible.
- Create balanced meals that provide an ideal macronutrient intake.
- Ensure an optimal protein intake. Protein is particularly important for helping preserve muscle mass as we age.
- Choose healthy, anti-inflammatory fats like olive oil over refined seed oils, deep fried foods and trans fats.
- Eat a diverse range of different plant foods. 30 plant foods a week has been shown to promote gut health and a diverse gut microbiome.
- Avoid sugar and refined, starchy carbohydrates which break down quickly into simple sugars.
- Avoid ultra processed foods.
EPIGENETIC AGE FAQS
Q: How soon can I expect changes in my epigenetic age if I improve my diet?
A: Changes in epigenetic age happen gradually and require consistent lifestyle adjustments. Studies suggest that with sustained healthy eating patterns over several months to years, you may see improvements in biological markers of ageing. Diet is one key factor; combining it with exercise and stress management can enhance results.
Q: Can dietary supplements replace healthy foods to reduce epigenetic ageing?
A: Whole foods like fruits, vegetables, nuts, and quality proteins offer a complex mix of nutrients, fibre, and antioxidants that supplements alone can’t fully replicate. While some supplements may support health, they should complement, not replace, a nutrient-dense, whole-food diet.
Q: Does exercise impact epigenetic age as well?
A: Yes, regular physical activity has been shown to positively influence epigenetic markers related to ageing. Exercise helps improve overall cellular function, reduce inflammation, and support healthy metabolism, making it a powerful partner to good nutrition for slowing biological ageing.
Q: How important is reducing sugar intake for epigenetic age
A: High added sugar consumption is linked to accelerated epigenetic ageing because it contributes to inflammation, insulin resistance, and metabolic stress. Reducing sugar helps protect your cells from damage and supports more youthful DNA methylation patterns.
Q: Are there specific foods I should focus on to slow my biological ageing?
A: Focus on nutrient-dense, whole foods such as leafy greens, colourful vegetables, berries, nuts, seeds, legumes, whole grains, olive oil, and quality proteins like fish and poultry. These foods provide antioxidants and anti-inflammatory compounds that support cellular health.
Q: Can stress or environmental factors affect my epigenetic age?
A: Yes, stress, pollution, smoking, and other environmental exposures can accelerate biological ageing by causing DNA damage and altering epigenetic markers. Managing stress through mindfulness, adequate sleep, and reducing toxin exposure complements dietary efforts.
Q: Is it ever too late to start improving my diet for epigenetic benefits?
A: It’s never too late to begin making healthier lifestyle choices. While starting earlier offers more potential benefit, positive changes at any age can contribute to slowing the biological ageing process and improving overall health.
Q: How can working with a nutritionist help me with epigenetic ageing?
A: A nutritionist provides personalised guidance to optimise your diet based on your unique health needs and goals. They offer tailored meal planning, motivation, accountability, and expert support to help you make sustainable changes that promote healthy ageing at the cellular level.
