Is this popular low-key diet the easiest way to stay healthy?

The Mediterranean diet has earned a reputation as one of the world's healthiest ways to eat.

Rooted in everyday foods, flexible habits and a relaxed approach to meals, it's a refreshing antidote to restrictive diets. Here's what it involves and the research-backed benefits.

Inspired by the diets of countries bordering the Mediterranean Sea, including Greece, Italy and parts of France, it focuses on whole, minimally processed foods. It is made up of:

Within that there's lots of flexibility – it's a diet you can adapt to your own ingredients, culture and preferences.

This way of eating gained popularity after scientists studied the health and diets of people living in the Mediterranean regions.

Studies have consistently found that following the Mediterranean diet is associated with:

These benefits seem to come from the overall pattern, not any specific 'superfood'.

A colourful, varied diet with healthy fats, whole grains and fibre-rich foods supports the heart, gut and immune system while reducing inflammation in the body.

So given there are clear health benefits, how can we make our diet more Mediterranean?

If there's one hallmark of the Mediterranean diet, it's variety.

Fresh, seasonal fruit and vegetables are eaten daily – but frozen, dried or tinned options also count, as long as they're minimally processed. Aiming for at least five different fruit and veg a day is a realistic goal, but more is even better.

Fruit is often eaten as dessert in Mediterranean cultures, replacing sugary puddings. It's an easy swap that boosts fibre and vitamins.

Carbohydrates also have a central role. Pasta, bread, rice and potatoes all feature regularly, but with an emphasis on whole grains whenever possible.

Wholemeal options provide more fibre and support digestive and heart health.

The Mediterranean diet embraces healthy fats, especially those from plants. Olive oil is so central to this way of eating, it's considered a defining feature of the diet.

Extra virgin olive oil, with its rich flavour and high antioxidant content, is often used for cooking, drizzling over vegetables or dressing salads. While there's no recommended minimum amount, research suggests that replacing saturated fats (like butter) with olive oil can support heart health.
