08 Aug This Diet Can Reduce Your Epigenetic Age
A new 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. 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.
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.
