The Mediterranean diet, explained
The principles of the Mediterranean diet, the foods at its core, and why it’s consistently ranked among the healthiest ways to eat.
Published
The Mediterranean diet is less a strict plan than a pattern of eating inspired by countries around the Mediterranean Sea. It emphasises whole, minimally processed foods, with plants at the centre and olive oil as the main fat.
It is repeatedly ranked among the healthiest dietary patterns and is associated with heart health — largely because of what it emphasises rather than any single ‘magic’ food.
What to eat often
- Vegetables, fruit, whole grains and legumes at most meals.
- Olive oil as the primary added fat.
- Fish and seafood a few times a week.
- Nuts, seeds and herbs and spices for flavour.
What to eat less

Frequently asked questions
- What can I eat on a Mediterranean diet?
- Mostly vegetables, fruit, whole grains, legumes, olive oil, nuts and fish, with poultry, eggs and dairy in moderation and red meat only occasionally.
- Is the Mediterranean diet good for weight loss?
- It can support a healthy weight because it favours filling, fibre-rich, minimally processed foods — but portion size and total calories still matter.
- Is olive oil healthy?
- Extra-virgin olive oil is rich in monounsaturated fat and is the primary fat in this pattern. It’s calorie-dense, so use it generously for flavour but mind portions if watching calories.
