The Mediterranean Diet: A Simple Guide to One of the Healthiest Ways to Eat

The Mediterranean diet isn’t a weight-loss plan with rules. It’s a way of eating based on vegetables, fruit, pulses, whole grains, nuts, olive oil and fish, with less red meat and processed food. It’s one of the best-studied eating patterns for heart health.

Imagine your doctor says your cholesterol is high and suggests “a Mediterranean diet.” You picture expensive olive oil and imported cheese. Then a dietitian shows you it can be beans, lentils, frozen vegetables, oats, tinned fish and a handful of nuts, foods available almost everywhere.

The basics

• Plenty of: vegetables, fruit, beans, lentils, whole grains, nuts and seeds
• Main fat: olive oil or other unsaturated oils
• Regularly: fish and seafood
• Moderate: poultry, eggs, yoghurt and cheese
• Less: red and processed meat, sugary foods and drinks, refined grains

Easy swaps

• White bread to wholegrain
• Butter for cooking to olive or rapeseed oil
• Crisps to a handful of unsalted nuts
• Half the meat in a stew to beans or lentils

But does it work outside the Mediterranean?

Yes. The principles can be adapted to any culture and budget: West African, South Asian and East Asian cuisines all have traditional dishes rich in vegetables, pulses and whole grains. Large studies, including a Spanish trial called PREDIMED, linked this pattern to fewer heart attacks and strokes.
