Mediterranean Diet Pros and Cons

Sharing is caring!


If you could eat delicious tasting foods while socializing with family and friends and partake in a fun and active physical lifestyle and improve the quality of your health, would you adopt this sustainable habit?

This blog will review the Mediterranean Diet pros and cons. There are so many health benefits to this type of lifestyle. I will show you how you can tweak the cons to make it work for you!

Mediterranean Diet History:

The Mediterranean Diet has been researched for over 60 years. Studies continue to result in favorable health outcomes. Today, the Mediterranean diet is considered one of the healthier dietary models worldwide.1

Dr. Ancel Keys first studied the Mediterranean Diet in 1945, but his work failed to garner attention until the fall of 1958 when he started his Seven Countries Study. The results of this study indicated that deaths from coronary heart disease and stroke in the United States and Northern Europe greatly exceeded those in Southern Europe. Further research indicated that there was a clear difference in the diet and lifestyle of these regions.1

What is the Mediterranean Diet?

Before looking at the Mediterranean Diet pros and cons we should first review what this eating pattern looks like. First, it is not just a diet, but a culinary tradition. This lifestyle includes eating fresh, simply prepared, delicious tasting foods with seasonal ingredients.

The lifestyle encourages daily physical activity, adequate rest, and focuses on enjoying meals commonly around a table shared with family and friends in a social and leisurely way.2

The Mediterranean Diet is a generic name for the traditional dietary patterns of individuals living along the 22 countries bordering the Mediterranean Sea. This culinary tradition is simple and straightforward. Eat more fresh, whole foods, in season. Focus on fresh fruits, vegetables, whole grains, nuts, seafood, and olive oil.

The Mediterranean Diet pros for your health summary:

The Mediterranean Diet protects against many chronic diseases. The diet is rich in nutrient dense foods that are good sources of antioxidants, carotenoids, and polyphenols. The Mediterranean Diet is also a good source of dietary fiber and healthy fats. This powerful combination helps improve our body’s defense mechanisms to fight many diseases.

The Mediterranean Diet pros: Environmental Protection:

The Mediterranean Diet is considered one of the most environmentally friendly sustainable diets. Results in lower ecological footprint. Mediterranean foods.

The Mediterranean Diet is considered one of the most environmentally sustainable diets. Heathy for the environment as well as the consumer.  It has a lower environmental impact than other dietary patterns mainly due to the larger consumption of plant foods. The lower consumption of animal foods leaves a lower water footprint and lower greenhouse gas emissions compared to other diet patterns.

The Mediterranean Diet is considered to have a low environmental impact, and therefore more sustainable due to its emphasis on plant- based foods, focusing on seasonable local products.

Results in better ecological footprint.

Increase local and in-season plant-derived food intake.

Attenuates the environmental pressure of food production.

Mitigates climate change2, lowered demands soil, water, and energy resources. 3,6

The Mediterranean diet is rich in disease fighting nutrients:

The Mediterranean Diet is rich in functional nutrients that promote health, including:

Polyphenols have anti-oxidative, anti-bacterial or anti-inflammatory effects, anti-proliferative actions that help keep blood vessels healthy, flexible, promote circulation and decrease chronic inflammation): Food sources include berries, black currants, plums ,sweet cherries, apples, black beans, white beans, hazelnuts, walnuts, almonds, pecans, artichokes, chicory, red onions, spinach, soy tempeh, tofu, black and green teas, and red wine. (*Risks associated with polyphenols is most heavily connected to taking polyphenol in supplement form.)

Mono-unsaturated fatty acids, omega-3-polyunsaturated fatty acid: Olive oil, nuts, fatty fish (Salmon, sardine, Atlantic mackerel, cod, herring, lake trout, canned light tuna)

Flavonoid’s: known for antioxidant properties. Found in onions, kale, red and purple grapes, red wine, berries, tomatoes ,lettuce, scallions, broccoli, white tea, black tea, apples, blueberries, strawberries, cocoa, chocolate, parsley, red peppers, celery, lemons, limes, oranges, grapefruit.

Fiber (prebiotics):  High fiber intake (complex and insoluble). Found in Fruits, vegetables, legumes, whole grains.

These super nutrients work on our body and cause increased resistance to stress, increased insulin sensitivity, increased immune function, increased microbiome diversity. Decreased inflammation, decreased oxidative stress, decreased metabolic syndrome, decreased obesity and type 2 diabetes, decreased LDL, decreased cardiovascular diseases, decreased colorectal cancer, decreased neurogenerative disorders. 5,8

Many properties in these powerful foods have not been identified. These food properties have shown to prevent or improve the management of chronic diseases.

Mediterranean Diet potential cons:

With all the decades of research and health benefits with the Mediterranean diet, what could possibly go wrong? Would there be any disadvantages following this type of lifestyle?

Will I gain weight on a Mediterranean diet?

The Mediterranean Diet lifestyle incorporates daily physical activity and employs moderation in food portions. It also encourages a higher volume of nutrient but not calorically dense vegetables, fruits, and whole grains daily, while avoiding processed foods. For more information on how to easily incorporate daily activity into your daily life see HAES Life-Enhancing Movement – Waistline Dietitian

Eating more fresh fruits, vegetables, unprocessed wholegrains, and healthy fats will help register your hunger and fullness sensations. These foods help our internal hunger and fullness mechanisms work more efficiently. You will likely feel more satisfied with the higher fiber food intake with less overall food. We typically eat more processed foods before we have the same level of contentment.

Research studies have shown that people following a Mediterranean diet had improved body weight, improved BMI (body mass index) and WC (Waist Circumference). The Mediterranean Diet can help you attain your health weight by balancing healthy food choices and using your own internal hunger and fullness cues. 1,12,20,21.

Is the Mediterranean Diet too high in carbohydrates?

The Mediterranean Diet limits sugar and sweets to special occasions. The type of carbohydrates allowed on the Mediterranean Diet are fresh fruits, vegetables, minimally processed whole grains and legumes. These carbohydrates are also a good source of fiber. Pairing a moderate portion of these higher fiber carbohydrates with healthy fat and lean proteins at meals is generally recommended.

The Mediterranean Diet positively affects microbiome diversity. This means that it improves the resilience and strength of your gut. This lowers oxidative stress and inflammation, while improving insulin sensitivity and immune function. Consequently, this reduces Type 2 Diabetes Mellitus as well as many other diseases.25 For more information on the benefits of prebiotics and probiotics see my fellow dietitians blog article The Difference Between Prebiotics and Probiotics: The Basics – The Mental Wellness Dietitian (

Studies have shown that people following the Mediterranean Diet had a reduction in developing diabetes as well as improved glucose control for people with diabetes.1,10,12,15,16,18.  If you have poorly controlled diabetes work closely with your doctor and registered dietitian to help you find the best balance of foods and medication to help you manage your blood sugar.

Arthur Ashe quote " Start where you are, use what you have, do what you can."

Should I really be drinking wine?

If you don’t already drink alcohol, don’t start. There are many other ways to get in the antioxidants from red wine. The polyphenol called resveratrol can also be found in grapes, grape juice, peanuts, pistachios, blueberries, cranberries, and dark chocolate.

The Mediterranean Diet allows up to one 5-ounce glass of Wine for women and two 5-ounce glasses of wine for men with one main meal a day. I have measured this out several times. This is not a lot of wine, and it would not be healthy to have more than this amount (studies show a negative effect on health with higher intakes.)

Some people should not drink at all, like women who are pregnant or trying to become pregnant, people under the age of 21 and people with certain health conditions. Some religions and social beliefs abstain from any alcohol. Herbal teas, or water is used in place.

If you do drink wine, limit to the portion size recommended to get the biggest health benefit! Moderation remains the key to overall health.

Will I become nutrient deficient because I am limiting red meat and dairy?

Many studies have indicated that people following the Mediterranean Diet eating pattern have good nutrient profiles and do not typically have any nutrient deficiencies. Bone mass and fractures were lower in people adhering to Mediterranean Diet, therefore indicating that getting adequate calcium and minerals is likely with a varied Mediterranean diet. Improved BMD (bone mass density) and lower fracture risk. 1,17,22,23,24.

The Mediterranean Diet limits red meat to less than 2 servings a week. Red meat is rich in iron, vitamin B12. You can continue to consume other foods rich in these nutrients:

Iron: Enriched breads, cereals, raisins, dried fruit, Egg yolk, spinach, and other leafy greens.

B12: Chicken, Fish, Dairy, Eggs, Fortified foods in B12 including fortified cereal, non-dairy milk, soy products.

The Mediterranean Diet limits dairy to two times a day. Other good sources of calcium and vitamin D include:

Calcium: Dark green leafy vegetables, edible fish bones, fortified juices, salmon, sardines with bones, shrimp, tofu.

Vitamin D is also in fatty fish and egg yolk.

How can I afford to go on a Mediterranean Diet?

Having less red meat and smaller portions of poultry and fish will reduce your grocery bill.

Cook more and eat out less. Many foods prepared at home are cheaper and more nutritious. Go back to basics and find a few simple healthy recipes your family enjoys.

The best way to save money at the grocery store is to plan. Plan your meals ahead of time. Check to see what foods you already have in the house and plan meals around food your already have most ingredients for first.  Then plan other meals around the sales.

When you go to the store, shop with a list to cut down on any extra purchase. Check the local sale advertisements and store coupons. Stock up on non-perishable sale items.

Shop for foods that are in season. Fruits and vegetables that are in season are usually less expensive. Buy just what you need so they do not go bad before you use them. Also have frozen vegetables and fruits on hand and buy them whenever they are on sale.

Focus on the nutritious lower cost foods such as beans, peas, and lentils, eggs, peanut butter, sweet or white potatoes, canned salmon, tuna, or crabmeat. Grains such as oats, brown rice, barley, or quinoa. Frozen and canned fruits and vegetables.

Life is a voyage. Adjust your sails towards health and vitality!

What if I do not have time to cook?

I would encourage you to begin slow and start small if this is new way of eating. Keep it simple. Start with gradually adjusting the meals you have been cooking with the healthier food and seasoning options. You may not have to change a lot.

Start by seeing what ingredients you already have available. Try to plan each week’s menus in advance.

Try a new recipe weekly. You may be able to modify some of your favorite recipes you already use and just focus on using the foods to include on the Mediterranean Diet.

Remember this is not a race but a journey. Cook once and eat twice. Every meal does not have to be perfect. Try starting out with one meal a day. Gradually grow to more and more.

Where’s the beef?

What if you cannot live without the beef? You do not have to eliminate red meat. Start by cutting back and eat it less often. Choose leaner cuts and trim visible fat before cooking, and use leaner cooking methods. Moderation is the key.

If these restrictions feel too strict, start slow and adapt what you can. Gradually build up.

What if I have a sweet tooth and cannot give up sugar?

You can start by using less sugar and eating fewer desserts. Replace some of your desserts with fruit. Try figs for a sweet taste after a meal.  Try adding other spices. Adding cinnamon to oatmeal. Reducing your sugar intake will help improve your overall health.
