Mediterranean Diet May Be Better for Heart Health, Study Finds

Eating well is more critical than ever as heart disease continues to be one of the biggest killers in the world. Scientists are still studying for what foods offer the best protection from cardiovascular disease. The Mediterranean diet is yet another diet that has shown to be one of the healthiest long-term approaches to heart health, according to a new scientific study.

The Mediterranean diet isn't a "diet" like others, where you cut out a food group; instead, it emphasizes a diversity of nutritious whole foods. New studies have shown that those who regularly stick to this diet may have a reduced risk of heart attacks, strokes, and cardiovascular deaths compared to those who adhere to low-fat diets.

In this article, we will discuss what the current research has shown, the scientific backing for the Mediterranean diet, the foods it encompasses, and some practical tips on how to make it a part of your daily diet.

What Is the Mediterranean Diet?

The Mediterranean diet is based on the traditional food habits of the Mediterranean countries, such as Greece, Italy and southern Spain. This is not a precise diet plan, but rather a general guide to eating that requires an abundance of fresh and highly processed foods.

The Mediterranean diet is not just about calorie restriction; it is a diet that promotes good food and good nutrition. It promotes consumption of foods that are rich in vitamins, minerals, antioxidants, healthy fats, and dietary fiber.

Common foods include:

• Extra virgin olive oil

• Fresh vegetables

• Seasonal fruits

• Whole grains

• Beans and lentils

• Nuts and seeds

• Fish and seafood

• Moderate amounts of yogurt and cheese.

• Herbs and spices rather than too much salt.

Usually restricted foods are:

• Processed meats

• Sugary beverages

• Refined carbohydrates

• Ultra-processed snacks

• Excessive sweets

This approach has been associated with better cardiovascular health, blood sugar control, healthy cholesterol levels and reduced inflammation.

What did the new research reveal?

A new study has been published that looked at long-term health outcomes of adults who followed various diets. Those who followed this Mediterranean diet closely had the same or better cardiovascular results compared to many people who were on standard low fat diets.

The study concluded that a greater adherence with the Mediterranean eating pattern was linked to:

Lower Risk of Cardiovascular Disease is the title of the story.

Those who ate the most fruits, vegetables, olive oil, legumes, whole grains and fish had the lowest rates of major cardiovascular events during the study.

The elimination of cholesterol from the body.

Improved cholesterol clearance.

Unsaturated fats, especially those found in olive oil and nuts, were effective at keeping cholesterol levels healthy, which included raising HDL ("good") cholesterol and keeping LDL ("bad") cholesterol levels in check when part of a healthy diet.

Reduced Chronic Inflammation

A number of the foods eaten in the Mediterranean are rich in antioxidants and anti-inflammatory compounds that can help lower chronic low-grade inflammation, one of the risk factors linked to cardiovascular disease.

Improved Overall Longevity

They also found that those who followed the Mediterranean diet more closely had reduced mortality from cardiovascular disease.

The results are positive but researchers warn that no one food can stop sickness. Rather, the overall diet and long-term healthy lifestyle are responsible for these benefits.

The importance of healthy fats and not just reducing fat intake.

Low-fat diets have long been touted as a way to prevent heart disease. But modern nutrition science has revealed that it's not always the amount of fat that matters, but rather the kind of fat that's eaten.

The Mediterranean diet swaps out saturated and trans fat for better unsaturated fats in these foods:

• Olive oil

• Walnuts

• Almonds

• Pistachios

• Avocados

• Salmon

• Sardines

• Mackerel

These foods are rich in omega-3 fatty acids and monounsaturated fats, which are important for regular heart activity, inflammation prevention, and healthy cholesterol levels.

The focus is now on eliminating fats and selecting healthy fats, and this has become one of the key aspects of contemporary dietary guidelines.

Key Nutrients That Support Heart Health

The Mediterranean diet will naturally supply a few nutrients that are linked to cardiovascular health.

Dietary Fiber

Vegetables, fruits, legumes, and whole grains provide fiber, which helps maintain healthy cholesterol and digestive health.

Omega-3 Fatty Acids

Fatty fish are rich in omega-3 fatty acids, linked to normal heart functioning and triglyceride reduction.

Antioxidants

Cancer-fighting antioxidants like vitamin C, vitamin E, and polyphenols are found in colorful fruits and vegetables, which help fight oxidative stress to the cells.

Potassium

Leafy green vegetables, beans, tomatoes, and bananas are rich in potassium, which is a key mineral needed for a healthy blood pressure.

Each section teaches how to eat and what to limit in your diet that is consistent with the Mediterranean diet.

The best part of the Mediterranean diet is that there are no calorie limits or restrictions on any food groups. Rather, it recommends consuming more healthful, less processed foods most of the time and less of certain foods that can be harmful to the cardiovascular system when consumed in large amounts.

Regular foods to eat

Make the majority of food choices from these nutrient-dense foods:

• Extra virgin olive oil

• Leafy green vegetables

• Tomatoes

• Cucumbers

• Bell peppers

• Broccoli

• Carrots

• Sweet potatoes

• Whole grains (brown rice, oats, quinoa, barley)

• Beans

• Lentils

• Chickpeas

• Almonds

• Walnuts

• Pistachios

• Sunflower seeds

• Chia seeds

• Flaxseeds

The best protein sources include fish, such as salmon, sardines, trout, and tuna.

• Skinless poultry

• Greek yogurt

• Moderate amounts of cheese

• Herbs and spices

• Plenty of water

Foods to Limit

Health benefits beyond heart health.

The primary known benefit of the Mediterranean diet is cardiovascular protection, but many other health benefits have been linked to it.

Aim for better blood sugar control

Foods high in fibre and healthy fats can help to promote better insulin sensitivity and healthy blood glucose levels.

Healthy Weight Management

Fiber and protein from whole foods keeps people full and satisfied, reducing the likelihood of overeating and resulting in a healthy body weight.

Improved Brain Health

Various studies indicate that following the Mediterranean diet long-term can contribute to good cognitive health and lower the chance of cognitive decline.

Decreased risk for some chronic diseases

Studies suggest that a Mediterranean diet could help reduce the risk of:

• Type 2 diabetes

• Metabolic syndrome

• High blood pressure

• Certain cancers

• Fatty liver disease

Better Gut Health

High-fiber vegetables, fruits, legumes and whole grains feed the good bacteria in the gut, which are essential for digestion, immunity and health.
