What is the Mediterranean diet?
“Mediterranean diet” generally describes a way of eating inspired by food traditions across countries bordering the Mediterranean Sea. There is no single official menu shared by every country or household. Common themes include eating plenty of plant foods, choosing minimally processed staples often, and using unsaturated fats in place of some sources of saturated fat.
The pattern is best understood as an overall approach to meals over time. You do not need specialty ingredients or to follow a rigid set of rules to take inspiration from it.
Foods commonly included
Vegetables and fruit
Choose a range of fresh, frozen or canned options. Use what is seasonal, accessible and convenient.
Beans and lentils
Chickpeas, kidney beans, peas, lentils and other pulses add variety, fibre and plant protein.
Whole grains
Oats, whole-wheat bread, brown rice, barley and other grains can be part of everyday meals.
Nuts and seeds
Use small handfuls or sprinkle them into porridge, salads and other dishes, considering allergies.
Unsaturated fats
Olive oil is a familiar example. Nuts, seeds and some other foods also provide unsaturated fats.
Protein choices
Fish, eggs, yoghurt, poultry, beans, tofu and other proteins can be selected to suit your needs and preferences.
Water can be a regular drink choice. Food traditions, health needs, allergies, access and personal preferences vary, so no single food is required for everyone.
Simple meal ideas
These examples are starting points, not a prescribed meal plan. Adjust portions and ingredients to your appetite, budget and dietary needs.
How to get started
- Add one plant food: include a vegetable, fruit, bean or lentil in a meal where it fits.
- Try a familiar whole grain: swap in oats or whole-wheat bread, or mix whole and refined grains if that feels more realistic.
- Vary protein sources: rotate among beans, lentils, eggs, fish, tofu, yoghurt or other options you enjoy.
- Review cooking fats: when appropriate, use unsaturated oils in place of some butter or other saturated-fat sources.
- Plan for your week: prepare a pot of beans or grains, wash produce, or make a simple soup to make balanced meals easier.
Change one or two habits at a time. A sustainable pattern should work with your life rather than require expensive foods, perfect meals or strict rules.
Common misunderstandings
It is not one fixed menu
Mediterranean regions have diverse cuisines. Recipes and ingredients can be adapted to local foods and cultural preferences.
It is not automatically a weight-loss plan
Eating patterns affect people differently, and body weight is influenced by many factors. This guide does not promise weight loss or prevent or treat any disease.
It does not mean unlimited portions
Foods such as oils and nuts can be nutritious, but individual energy needs and portions still vary. Choose amounts that work for you.
It can be adapted for vegetarian eating
Beans, lentils, nuts, seeds, tofu, eggs and dairy foods where used can provide options. People with specific nutrient needs may benefit from advice from a qualified dietitian.
