The internet is awash with information on the best diets to follow — and navigating this maelstrom of tips and tricks can be daunting. One that frequently crops up in this space is the Mediterranean diet.

Inspired by the foods of sun-soaked and olive-rich countries such as Spain, Greece and Italy, this traditional diet has a reputation for being both delicious and healthy.

But according to UNESCO, the diet entails much more than just food intake: “[It] involves a set of skills, knowledge, rituals, symbols and traditions concerning crops, harvesting, fishing, animal husbandry, conservation, processing, cooking, and particularly the sharing and consumption of food.”

The Main Foods in the Mediterranean Diet

Though the exact approach and recipes may vary, the diet generally consists of a lot of fruits, vegetables and legumes, and red wine is also commonly drunk with food — in moderation.

More specifically, the main food in a Mediterranean diet should include fruits and vegetables (aim for two to three and at least four servings daily), whole grains (at least three ounces daily for a 2,000 calorie diet), and unsaturated plant fats like olive oil, according to the Mayo Clinic. 

Also recommended is eating seafood, especially fish such as tuna and salmon, two to three times a week while avoiding deep-fried varieties, and includes four weekly servings of raw, unsalted nuts.

Foods Not Allowed in the Mediterranean Diet

If you are thinking about starting a Mediterranean diet, there are also some foods to avoid

This includes treating sweets as occasional treats rather than daily staples, using red meat sparingly as more of a garnish, and steering clear of processed food and meat like buttery crackers and potato chips. 

Alcohol consumption should be moderate, primarily focusing on red wine. Healthy fat alternatives such as olive oil are preferred over butter, and whole-fat dairy products, along with sugary drinks, including fruit juices, are to be consumed very rarely, promoting a pattern rich in whole foods and healthy fats.

The cultural aspects of the diet – centered around traditional consumption of food and socialization – likely play a role in its health benefits in countries where it originated. Exercise is also a factor. 

Simon Poole, a Mediterranean diet expert and author of The Real Mediterranean Diet, says it’s also possible to separate these aspects. One doesn’t necessarily need to change an entire lifestyle to derive benefits from the diet. Evidence shows that following these eating habits can have a real impact in a variety of ways, he says.

“You can look at the individual ingredients and run through all those vegetables, fruits, legumes, herbs, spices, nuts, olive oil, fish, and pinpoint health benefits," Poole says.

Taken together, they provide “excellent quality carbohydrates, fats, and proteins and high levels of vitamins, minerals, antioxidants, and more,” he adds. Also, consider common food ingredients that are being avoided in this diet: red meat, highly processed foods and added sugars. In a nutshell, yes, the Mediterranean diet is healthy! As such, health professionals often prescribe the diet to patients.

How to Start a Mediterranean Diet

Switching to a diet of this kind may appear “revolutionary” for some at first, says Poole. But following it doesn’t have to be complicated and can always be done in steps.

“The first challenge is to really ramp up the colored vegetables in people's diets,” he says.

Next, try kicking processed foods from the menu and increasing the use of herbs, spices and extra virgin olive oil in meals. Reducing red meat and dairy consumption could follow. Thankfully, you can now find many easy-to-follow recipes online and in cookbooks.

Costs can be another potential barrier that puts people off. But Poole says it doesn’t have to come with a high price tag: “I think the key message is that it's not all expensive foods such as pistachios and pomegranates. It really is all about vegetables and cooking from scratch.”

Now that you know how healthy a Mediterranean diet is and how to start one, you may already be considering ways to manage a healthier lifestyle!
