The Mediterranean Diet

The Mediterranean diet is based on the traditional foods that people used to eat in countries like Italy and Greece. Researchers noted that the people were exceptionally healthy compared to Americans and had a risk of an increasing number of lifestyle diseases.
Numerous studies have now shown that the Mediterranean diet can cause weight loss and help prevent heart attacks, strokes, type 2 diabetes, and premature death.

There is no one right way to follow the Mediterranean diet, as there are many countries around the Mediterranean Sea and people in different areas eat different foods.

Consider these notes as a general guideline, not something written in stone. The plan can be adjusted to your individual needs and preferences.

THE BASICS

  • EAT: Vegetables, fruits, nuts, seeds, legumes, potatoes, whole grains, breads, herbs, spices, fish, seafood, and extra virgin olive oil.
  • EAT IN MODERATION: Poultry, eggs, cheese, and yogurt.
  • EAT ONLY RARELY: Red meat.
  • DON’T EAT: Sugar-sweetened beverages, added sugars, processed meat, refined grains, refined oils, and other highly processed foods.

 

AVOID THESE UNHEALTHY FOODS

You should avoid these unhealthy foods and ingredients:

  • ADDED SUGAR: Soda, candies, ice cream, table sugar and many others.
  • REFINED GRAINS: White bread, pasta made with refined wheat, etc.
  • TRANS FATS: Found in margarine and various processed foods.
  • REFINED OILS: Soybean oil, canola oil, cottonseed oil and others.
  • PROCESSED MEAT: Processed sausages, hot dogs, etc.
  • HIGHLY PROCESSED FOODS: Anything labelled “low-fat” or “diet” or which looks like it was made in a factory.

 

You must read food labels carefully if you want to avoid these unhealthy ingredients.

FOODS TO EAT

Exactly which foods belong to the Mediterranean diet is controversial, partly because there is such variation between different countries.

The diet examined by most studies is high in healthy plant foods and relatively low in animal foods.

However, eating fish and seafood is recommended at least twice a week. The Mediterranean lifestyle also involves regular physical activity, sharing meals with other people and enjoying life.

You should base your diet on these healthy, unprocessed Mediterranean foods:

  • VEGETABLES: Tomatoes, broccoli, kale, spinach, onions, cauliflower, carrots, Brussels sprouts, cucumbers, etc.
  • FRUITS: Apples, bananas, oranges, pears, strawberries, grapes, dates, figs, melons, peaches, etc.
  • NUTS AND SEEDS: Almonds, walnuts, macadamia nuts, hazelnuts, cashews, sunflower seeds, pumpkin seeds, etc.
  • LEGUMES: Beans, peas, lentils, pulses, peanuts, chickpeas, etc.
  • TUBERS: Potatoes, sweet potatoes, turnips, yams, etc.
  • WHOLE GRAINS: Whole oats, brown rice, rye, barley, corn, buckwheat, whole wheat, whole-grain bread, and pasta.
  • FISH AND SEAFOOD: Salmon, sardines, trout, tuna, mackerel, shrimp, oysters, clams, crab, mussels, etc.
  • POULTRY: Chicken, duck, turkey, etc.
  • EGGS: Chicken, quail, and duck eggs.
  • DAIRY: Cheese, yogurt, Greek yogurt, etc.
  • HERBS AND SPICES: Garlic, basil, mint, rosemary, sage, nutmeg, cinnamon, pepper, etc.
  • HEALTHY FATS: Extra virgin olive oil, olives, avocados, and avocado oil.

Whole, single-ingredient foods are the key to good health.

WHAT TO DRINK

Water should be your go-to beverage on a Mediterranean diet. This diet also includes moderate amounts of red wine — around 1 glass per day.

However, this is completely optional, and wine should be avoided by anyone with alcoholism or problems controlling their consumption.

Coffee and tea are also completely acceptable, but you should avoid sugar- sweetened beverages and fruit juices, which are very high in sugar.

BENEFITS AND NEGATIVES OF THE MEDITERRANEAN DIET

BENEFITS

There have been numerous studies documenting the health benefits of the Mediterranean diet.

GENERAL NUTRITION

The Mediterranean diet does not eliminate any food groups and encourages a variety of nutrient-dense foods, making it easy to meet your nutritional needs and enjoy a wide range of foods and flavours.

HEART HEALTH

Scientists have conducted a robust amount of research on the Mediterranean diet and heart health. The results show that there is clear evidence to support the Mediterranean diet for better heart health.

For example, a review study in the European Journal of Clinical Nutrition concluded that following a Mediterranean diet is associated with reduced risk of coronary heart disease, heart attack, and overall mortality.

Research review published in 2019, study authors wrote that the available evidence is “large, strong, and consistent” supporting this diet for reduced rates of coronary heart disease, ischemic stroke, and total cardiovascular disease.

BETTER DIABETES PREVENTION AND MANAGEMENT

Following the Mediterranean diet may help those with type 2 diabetes achieve better blood sugar control.

A systematic review of 56 trials between 1978 to 2016 and including 4,937 patients with type 2 diabetes found that the Mediterranean diet, as compared with control diets, was able to lower haemoglobin A1c levels by up to 0.32% on average.

Haemoglobin A1c reflects the body’s blood sugar control over the last three months. Though it sounds small, any reduction may be helpful for people with diabetes who are trying to manage blood sugar levels.

IMPROVED MENTAL HEALTH

One surprising benefit may be a connection between the Mediterranean diet and better mental health, according to the Director of Nutrition for Oldways, a non-profit organization that promotes healthy food and nutrition.

In fact, a 2018 study in Molecular Psychiatry found that following a Mediterranean diet is associated with reduced risk of depressive symptoms or clinical depression.

In addition, consider the emphasis on social connections in the Mediterranean lifestyle. This is paramount for mental health, particularly among older adults.

Maintaining friendships and regular social interaction can reduce loneliness, which is known to be positive for overall health.

WEIGHT MANAGEMENT

It seems counterintuitive that a diet which emphasizes calorically-dense olive oil and nuts could help with weight management. However, these satiating fats–in conjunction with the many fibre-rich vegetables and fruits recommended—can help you feel fuller for longer.

Indeed, research has found that people do not gain weight when following a Mediterranean diet. In fact, some studies have suggested the Mediterranean diet and low-carbohydrate diets lead to similar rates of weight loss after one year.

REDUCES INFLAMMATORY MARKERS

Researchers have been conducting trials establishing connections between certain inflammatory markers and chronic disease.

For example, higher levels of two inflammatory markers (interleukin 6 and C-reactive protein) are thought to be associated with an increased risk of diabetes. Research shows the Mediterranean diet is associated with lower levels of these inflammatory markers.

CANCER PREVENTION

Most cases of cancer are not caused by a singular factor, but rather a combination of many genetic and environmental factors. Diet can play a role in this complex disease, and certain dietary patterns—including the Mediterranean diet—are associated with a reduced risk of cancer.

A meta-analysis found that those who adhered most closely to the Mediterranean diet had a lower risk of developing colorectal cancer, breast cancer, gastric cancer, liver cancer, head and neck cancer, and prostate cancer.

BETTER FOR THE ENVIRONMENT

Diets that rely less on beef and more on grains and other plant-based foods have been shown to be healthier for the planet as a Mediterranean diet saves water, conserves land, and cuts fertilizer use.

NEGATIVES

For some people, there may be a few drawbacks to the Mediterranean diet. However, many of these negatives are minimal.

COST

There are no expensive branded foods or special supplements that you are required to buy on the Mediterranean diet. But some consumers express concern about the cost of some foods, including fish, seeds, nuts, and olive oil. For example, fresh seafood tends to be more expensive than other proteins.

ADDITIONAL GUIDANCE MAY BE NEEDED

Even though studies suggest that a Mediterranean diet may reduce diabetes risk and support better blood sugar control, some people with diabetes may need additional guidance while on this diet.

Because there is an emphasis on grains, fruits, and vegetables (including starchy vegetables), meals may be high in carbohydrates. It’s important for people with diabetes to eat a consistent, controlled amount of carbohydrates throughout the day to avoid blood sugar spikes or dangerously low sugars (if you’re using insulin or certain oral medications).

This does not mean people with diabetes shouldn’t follow this plan. On the contrary, it can be a great choice. If you have diabetes, though, try working with a dietitian to help you plan the right carbohydrate counts for your meals within the greater framework of the Mediterranean diet.

RESTRICTIONS MAY FEEL CHALLENGING

This diet recommends reducing red meat and added sugar consumption, which may be difficult for some people. Those who are used to a more standard diet may consume added sugar in processed foods on a regular basis. Those following the Mediterranean diet are advised to save added sugar specifically for special occasions.

Keep in mind any added sugar reduction is beneficial, so don’t let this deter you. Following a Mediterranean style diet that contains a little added sugar is still more beneficial than following a diet that’s high in added sugar.

Similarly, if you’re struggling with eating red meat less often, try following this diet while incorporating lean and unprocessed red meats like flank, top round, and brisket half flat, but in smaller portions. Research suggests you’ll still reap heart-health benefits.

CONCERNS ABOUT ALCOHOL INTAKE

Some experts raise concerns about the regular alcohol intake (particularly wine) in the Mediterranean diet and whether this is truly beneficial to recommend. When alcohol is consumed as part of a balanced meal, and coupled with daily movement and social connections, studies find a net health benefit.

The Mediterranean diet and other traditional diets present examples of how to safely enjoy alcohol in moderation (up to one 5-ounce glass of wine per day for women, or up to two 5-ounce glasses daily for men), in a way that may support cardiometabolic health and help to foster positive social connections.

But what about when alcohol is consumed in other scenarios? When alcohol intake is accompanied by unhealthy habits, like smoking or poor diet, or unsafe habits, like driving, obvious health risks present themselves. When adults choose to drink, its recommended one drink or less per day for women and two drinks or less for men.
