What Is The Mediterranean Diet?

The Mediterranean diet is a healthy eating and lifestyle plan followed by people living in the Mediterranean basin.

Alexandre Meybeck, the coordinator of Sustainable Food Systems Program, United Nations Food and Agriculture Organization (FAO), said, “The Mediterranean diet is nutritious, integrated into local cultures, environmentally sustainable and it supports local economies” (5).

The food pyramid describes the Mediterranean diet quite sensibly. It encourages you to consume fresh and healthy foods and limit the consumption of animal protein and requires you to be physically active.

You may wonder who created this diet and why it allows you to consume bread, which is simple carb and may cause weight gain. To find the answer, take a quick look at the evolution of the Mediterranean diet.

An Interesting Evolution Of The Mediterranean Diet

The origin of the Mediterranean diet can be traced back to the Middle Ages when the Mediterranean region was the cultural hubspot for Romans, Greeks, Parisians, Babylonians, Assyrians, and Sumerians.

Bread, wine, oil, sheep cheese, home-grown vegetables, fish, seafood, and meat were popular foods. Cereals were mainly eaten by the poor as they helped them feel full for a long duration.

Later, the Islamic culture introduced pomegranate (talk about baba ganoush), almonds, oranges, lemons, and rose water. They also introduced some high-priced exotic plants like sugarcane, rice, spinach, eggplant, and spices that were only consumed by wealthy people. Tomato, which was considered an inedible ornament fruit, was imported from America and was the first red vegetable to be introduced in Mediterranean cuisine (2).

Fast forward to 1957, Dr. Ancel Keys was the first to define the Mediterranean style of eating and living that protected the populace from the diseases that crippled the West (6). He conducted the famous “Seven Countries Study” in the US, Italy, Greece, Yugoslavia, the Netherlands, Finland, and Japan. He found that a diet high in saturated fat and smoking are the reasons for the rise in CVDs in the West, unlike in the Mediterranean region (7).

In 2018 and 2019, several studies have confirmed that the Mediterranean diet helped reduce abdominal obesity and the risk of diabetes type II (8), (9). But that’s just the tip of the iceberg. Here’s a list of benefits of following the Mediterranean diet.

How Does The Mediterranean Diet Work?

The Mediterranean diet works in the following ways:

  • Fruits, veggies, and whole grains are great sources of dietary fiber, which helps improve digestion and bowel movement (17). Dietary fiber also helps lower LDL cholesterol and regulates blood glucose levels (18).
  • Lean protein and a limited amount of red meat make this diet extremely heart-friendly. Protein helps to build lean muscle mass, which, in turn, boosts metabolism (19), (20). Vegans and vegetarians may consume legumes, nuts, and seeds for protein.
  • Yogurt and cheese are great sources of calcium, good gut bacteria, and protein. Yogurt helps improve digestion by increasing the number and variety of good gut bacteria (21).
  • Fish, nuts, olive oil, and seeds are loaded with healthy fats that prevent inflammation and inflammation-induced weight gain (22).
    Before you get all excited and start following the Mediterranean diet, take a quick look at the following guidelines.

Lifestyle Changes

  • Workout regularly. Do what interests you and is convenient for you. If lifting weights every day is not your thing, you may go for Zumba or kickboxing or swimming.
  • Stick to your diet. Did you know that your health is more dependant on your diet than the number of hours you spend at the gym? If you want to see results, you must adhere to your diet.
  • Enjoy the foods you like. But you may do it only once a week and only if you adhered to the diet. Indulging once a week will prevent you from losing interest in the Mediterranean diet. Click here to know the 10 strategies of enjoying a cheat meal.
  • Practice portion control. If you go way beyond your calorie limits, it can be a problem, especially while having a cheat meal. The mantra is to control portions or eat everything in moderation.
  • Take stress out of the equation. Otherwise, your effort will just go down the drain. Stress increases harmful free oxygen radicals, which increase inflammation in the body. As a result, your vital organs, like the heart, lungs, skin, and liver, may get affected. Moreover, stress also increases abdominal fat and the risk of diabetes type II.
  • Sleep. Do not undermine the strength of sleep. Your brain is just like your laptop. It needs to shut down for a while to prevent overheating and malfunctioning. Get at least 6 hours of undisturbed sleep.
  • Pick up a hobby. Do you like to dance? Sing or paint? Play sports or experiment with makeup? The point is to keep yourself busy in a way that will help you detox and de-stress. Don’t think anymore. There’s no better time than doing it now!
  • Drink wine. Alone or with friends, consume a glass of wine if you are in the ‘party mode’.
  • Eat home-cooked meals. Restaurant food is loaded with invisible calories, preservatives, food color, and taste enhancers that are harmful to your health. So, consume home-cooked meals at least 99% of the times.

If you are new to cooking or dread cooking, here are a few simple and easy Mediterranean diet recipes for you. Take a look.

Frequently Asked Questions

Can I eat peanut butter while on the Mediterranean diet?

If the peanut butter is 100% organic, you can consume it. However, the peanut butter that is sold in supermarkets contains preservatives, which is a no-no in the Mediterranean diet. Yes, peanut butter is definitely a better option compared to butter, but make sure it does not contain any artificial flavoring, coloring, and preserving agents.

Is the Mediterranean Diet similar to the Paleo diet?

No, the Paleo diet excludes grains such as brown rice, quinoa, wheat, kidney beans, garbanzo beans, etc. That’s because the Paleo diet is a diet that humans of the Paleolithic age followed, and cooking grains was not a practice at that time. Also, in the Mediterranean diet, you are required to consume legumes and grains.

Is the Mediterranean diet similar to the Ketogenic diet?

No, the ketogenic diet requires you to eat a lot of fat, moderate protein, and very less amount of carbs. In the Mediterranean diet, you will consume a lot of olive oil, but you will also consume a lot of veggies and fruits that contain complex carbs or good carbs and a moderate amount of proteins.
