The Mediterranean diet, rich in fibre, healthy fats and diverse plant-based foods, has been shown to support gut microbiome diversity and overall digestive health. Emerging research highlights its role in reducing inflammation and promoting beneficial gut bacteria, contributing to improved metabolic and immune function.
What Is the Mediterranean Diet?
The Mediterranean diet refers to a diet consumed in Mediterranean countries such as Spain, Greece and Italy. It is heavy in vegetables, beans, legumes, cereal, fruit and nuts, and low in red meat and dairy. It is also typically lower in saturated fats, sugar and processed foods, making it a healthier option compared to typical Western diets and a firm favourite of yoga teacher and long-time vegetarian Isis Monteverde.
The Mediterranean diet is not a low-fat diet, but it does favour unsaturated fats such as olive oil, making it a more heart-healthy option. It is also rich in omega 3 fatty acids, potassium, antioxidants (including vitamins E and C), B-vitamins (including folic acid) and (perhaps most importantly for gut health) fibre.
Gut Health and Why It Is Important
When using the word ‘gut’ most people instinctively think of just the stomach, but in the context of gut health the term refers to the entire digestive system: the long tube that turns food into energy and keeps the human body functioning and healthy.
In the past couple of decades, this system has been studied more in depth, giving scientists a better understanding of how big an effect gut health has on our overall health. The human body has millions of beneficial microbes, most of which can be found in our digestive system. They not only play an important part in digestion but also in things like immune function and weight regulation. The food we eat affects the bacteria in our gut, and therefore, the diet we consume matters greatly in relation to our gut health.
Mediterranean Diet and Gut Health
As the Mediterranean diet is varied, fresh and fibre heavy, it has been suggested to be very beneficial for general gut health. The diverse range of microbes that live in the human gut thrive on the plant-based foods that the Mediterranean diet offers, and the fibre and wholegrains help to feed the healthy bacteria. This is especially important, as it is this ‘good’ microbiome that keeps our guts healthy. Equally, higher fibre intake has been linked to decreased risk of bowl cancer, with the risk of developing the condition decreasing 11% by adding just 10g of extra fibre into the daily diet.
