With more than 20 years of experience as a cardiac dietitian, I have seen our understanding of what constitutes a “heart-healthy diet” evolve—from a focus on low-fat and plant-based eating to a greater emphasis on whole foods and, importantly, what we can add to our diet rather than what we should avoid.
There is so much conflicting nutrition information out there—from eggs to oils—that it is easy to get caught up in one food or nutrient. But when it comes to heart health, the whole picture matters. I am often interviewed about the latest food trends and asked, “Is this good for you?” My answer is almost always the same: No single food determines your health. It is the combination of foods you eat over time that matters most.
Over the past decade, the well-studied Mediterranean dietary pattern has consistently been recognized as one of the leading approaches to heart-healthy eating. I counsel my patients on the principles of a Mediterranean-style pattern because there is no specific “Mediterranean diet” that everyone needs to follow.
The research from the Seven Countries Study helped draw attention to the relationship between dietary fat, saturated fat, and coronary heart disease and played an important role in popularizing the Mediterranean dietary pattern in nutrition research.
It is also important to remember that there is no single traditional Mediterranean diet. Eating patterns have historically varied considerably among the countries and regions surrounding the Mediterranean Sea, influenced by culture, agriculture, religion, and economics. However, common themes include vegetables, fruits, legumes, whole grains, nuts, olive oil, fish, and relatively modest amounts of meat.
What Does a Mediterranean-Style Pattern Look Like?
I have broken down what a Mediterranean-style pattern of eating looks like below. More importantly, the focus is on the overall pattern of eating—emphasizing foods that support heart health rather than focusing primarily on foods to limit or avoid.
Emphasize:
● Vegetables and fruits with meals and throughout the day
● Beans, lentils, and other legumes on a regular basis
● Whole grains in place of refined grains
● Nuts and seeds as nutrient-dense snack options
● Extra-virgin olive oil in place of butter and other sources of saturated fat
● Fish and seafood regularly, particularly in place of some red or processed meat
● Herbs and spices to add flavor while reducing reliance on excess salt
● Moderate amounts of yogurt, cheese, poultry, and eggs
Limit:
● Processed and red meats
● Highly processed foods
● Added sugars and sugary beverages
● Refined grains
● Foods high in saturated fat
● Excess sodium
It’s More Than What’s on Your Plate
There are important traditional Mediterranean lifestyle patterns that should not be overlooked, as they can also contribute to overall health and well-being.
● Eating meals socially
● Cooking and preparing meals at home
● Enjoying food rather than labeling foods as “good” or “bad”
● Regular physical activity
● Choosing seasonal and locally available foods when possible
● Eating mindfully and taking time to enjoy meals
The Mediterranean pattern isn't about following a perfect menu. It's about building a dietary pattern around minimally processed plant foods, unsaturated fats, seafood, and other nutrient-dense foods while making highly processed foods and processed meats occasional rather than everyday choices.
This reflects an important principle in heart-healthy nutrition: the overall dietary pattern matters more than any individual “superfood.”
The Dietitian’s Bottom Line
A heart-healthy lifestyle doesn’t begin with a perfect meal plan. It begins with small, sustainable choices: adding another vegetable, choosing whole grains, reaching for olive oil, including beans or fish, sharing a meal, or simply making time to enjoy the food on your plate.
Heart-healthy eating isn’t about perfection. It’s about the pattern—the choices we make, enjoy, and return to day after day.
