Benefits of the Mediterranean Diet: How This Eating Plan Boosts Heart Health and Longevity

In 2010, the American Heart Association came up with ‘Life’s Simple 7’ , seven practices you can easily incorporate into your daily life to help maintain a healthy heart.  One of those key activities is eating a healthy diet. So, if your goal is to tick off boxes on a heart-health checklist, eating well is crucial, which leads us to the Mediterranean Diet.

The Mediterranean Diet has soared in global popularity due to its delicious and nutritious nature, readily available ingredient options, and ease of implementation. It’s not just foodies and health-conscious people who are raving about it. Experts have consistently recognized the Mediterranean Diet as the best overall eating plan for health. In fact, a recent Harris Poll survey with U.S. News & World Report confirms its reign as the top health plan for 2024.

For the seventh year in a row, the Mediterranean Diet has topped the charts with 85.1% popularity. Its secret? A focus on overall diet quality. This means prioritizing daily consumption of fruits, vegetables, whole grains, beans, nuts, legumes, olive oil, herbs, and spices instead of focusing on a single nutrient or food group.

One of the standout benefits of the Mediterranean Diet is its positive impact on cardiovascular health. This eating plan is rich in heart-healthy fats, antioxidants, and anti-inflammatory ingredients that work together to support a healthy heart. It helps improve cholesterol levels, regulate blood pressure, and support overall heart health. In short, it’s a heart’s best friend.

What is the Mediterranean Diet?

The Mediterranean Diet, or MedDiet, is based on the traditional eating habits of people living around the Mediterranean Sea including Greece, Italy, and Spain. The diet first gained attention in the 1950s when researchers observed that Europeans living in rural areas near the Mediterranean Sea had a higher life expectancy than those in other parts of Europe, despite having less access to advanced medical services and a lower standard of living.

Being regionally based, local civilizations have relied on what their lands produced naturally. Historically, red meat including beef, pork and lamb was reserved and prepared on special occasions therefore, consumption was limited. They hardly ever ate processed meats, butter, ice cream, or whole-fat dairy products, except for cheese and yogurt in moderation.

Key Components of the Mediterranean Diet

The Mediterranean Diet stands out from other diets due to its low sugar and processed food content.

• The main source of fat in the Mediterranean Diet is extra-virgin olive oil (EVOO). Additionally, red wine is frequently consumed in moderation with meals. Extra-virgin olive oil and red wine both contain compounds known as polyphenols, which are touted by health experts for their anti-inflammatory benefits.
• Minimally processed, locally grown vegetables, fruits, and unrefined grains also serve as a foundation.

• Legumes and nuts are a part of the Mediterranean Diet. These are great sources of plant-based proteins and healthy fats. They provide essential nutrients like magnesium and potassium, which are beneficial for heart health.

• Fish and shellfish are common, especially for those living near the sea.

• Foods like whole wheat, oats, and barley are excellent sources of fiber and essential nutrients. They help maintain stable blood sugar levels and promote a healthy digestive system.

How Exactly Does the Mediterranean Diet Support Cardiovascular Health?  A Glimpse at The Science:

·        Reduction in Cardiovascular Disease Risk

The Mediterranean Diet has been a hot topic for researchers, and for good reason—it significantly lowers the risk of heart disease. Researchers have found that people who stick closely to this diet, compared those who do not, have a 50 to 70% lower chance of developing cardiovascular diseases. Another detailed analysis of 16 studies focused on women has revealed that those who followed the Mediterranean Diet had reduced mortality due to heart disease.

Key components of the Mediterranean diet include olive oil and fatty fish rich in Omega-3 fatty acids. These foods help reduce inflammation and keep bad cholesterol (LDL) in check, protecting your heart in the process.

Research also shows that increasing your intake of olive oil can lower your long-term risk of heart disease and even reduce the likelihood of death. Simply replacing fats like butter and margarine with olive oil can make a big difference in maintaining a healthy heart.

Moreover, eating fatty fish a few times a week significantly lowers the risk of death from heart disease. People who eat fish regularly have a 21% to 34% lower risk compared to those who don’t eat fish.

Omega-3s improve heart health by lowering triglycerides, raising good cholesterol, preventing artery blockages, increasing artery flexibility, and reducing inflammation. Including fatty fish and omega-3 supplements in your diet can significantly improve heart health. Omega-3 fatty acids also help stabilize heart rhythms, reducing the risk of irregular heartbeats known as arrhythmias which can lead to severe cardiac events.

·        Cholesterol Improvement

There are two main types of cholesterol: LDL also known as (bad) and HDL referred to as (good). High levels of LDL contribute to cardiovascular disease when they are deposited in artery walls that have been damaged by high blood pressure, chronic inflammation, and/or oxidative stress.  Conversely, HDL cholesterol helps remove bad cholesterol from your bloodstream, lowering heart disease risk.

The Mediterranean diet boosts HDL (good) cholesterol levels by increasing consumption of unsaturated fats over saturated fats. Unsaturated fats, found in foods like olive oil, lower LDL (bad) cholesterol and increase HDL cholesterol. The MedDiet also includes fiber-rich foods like whole grains, which help reduce LDL cholesterol.

·        Blood Pressure Regulation

Nearly half of U.S. adults deal with high blood pressure, which can lead to serious health problems if not treated. Making lifestyle changes like following a healthy diet can significantly help manage high blood pressure.

Researchers from Harokopio University in Greece conducted a study over 20 years, beginning in 2002, with more than 3,000 participants who did NOT have high blood pressure. They kept track of how well participants followed the Mediterranean Diet and monitored their health over the years. The results showed that following the Mediterranean Diet consistently over 20 years reduced the risk of high blood pressure by 46.5%.

Olive oil, a key part of the Mediterranean Diet, helps keep blood vessels relaxed and open, which is essential for maintaining healthy blood pressure levels.  Fruits, vegetables, and legumes, also mainstays of the Mediterranean Diet, are rich in potassium and magnesium. Both potassium and magnesium help relax blood vessels and play a vital role in controlling high blood pressure.

Mediterranean Diet for Longevity

Studies using advanced tests, like epigenetic biological age tests, have highlighted how the Mediterranean Diet can positively affect our biological age, which is a measure of how old our bodies really are, not just our calendar age.

One study published in GeroScience found that following a Mediterranean-like diet can significantly slow down our biological aging. This means that people who stick to this diet stay younger, biologically speaking, for longer. The benefits are not just because the diet boosts the immune system, but also due to specific foods in the diet.

Eating plenty of fish, fruits, vegetables, and poultry—key components of the Mediterranean Diet—can improve your body’s biological age. Additionally, vitamins like B12 and folate, found in many Mediterranean foods, play a vital role in preserving your DNA and keep you youthful.

On the flip side, high levels of glucose, inflammation, being overweight, having a high waist-to-hip ratio, high triglycerides, high blood pressure, and low HDL cholesterol can all speed up your biological aging. By managing these factors, you can potentially lower your biological age.

The Mediterranean Diet focuses on eight key dietary components that can help you stay biologically younger:

1. Eating more vegetables and fruits
2. Eating more nuts and legumes
3. Eating more whole grains
4. Choosing low-fat dairy instead of full fat
5. Cutting back on dairy
6. Eating less red and processed meat
7. Limiting sugary drinks
8. Reducing salt intake

Mediterranean Diet Reduces the Risk of Chronic Diseases

Following the Mediterranean Diet can help you avoid many chronic diseases. For example, because the diet focuses on a balanced intake of nutrients and low levels of processed sugars, it significantly lowers the risk of type 2 diabetes and metabolic syndrome. In fact, a 2014 meta-analysis found that people who follow the Mediterranean Diet have a 23% lower risk of developing type 2 diabetes. Key components of diet – whole foods, healthy fats, and fiber-rich foods help maintain steady blood sugar levels and improve insulin sensitivity.

In terms of cancer prevention, the Mediterranean Diet’s high content of antioxidants and anti-inflammatory compounds is beneficial. A systematic review  has highlighted that adherence to this diet was associated with a reduced risk of various cancers, including breast and colorectal cancers.

Cognitive Health Benefits of Mediterranean Diet

Research published in “Frontiers in Nutrition” suggests that the anti-inflammatory and antioxidant properties of the Mediterranean Diet help protect brain health. By reducing inflammation and oxidative stress in the brain, the Mediterranean Diet supports cognitive function and helps prevent neurodegenerative diseases.
