The Ultimate Beginner's Guide to the Mediterranean Diet for a Heart-Healthy Lifestyle

The Mediterranean diet is a way of eating based on the traditional cuisine of countries bordering the Mediterranean Sea. It's more than just a diet; it's a lifestyle. Rich in fruits, vegetables, whole grains, and heart-healthy fats, it can help manage your weight, protect your heart, and prevent diabetes. If you're looking for a heart-healthy eating plan, the Mediterranean diet might be right for you. It is one of the healthy eating plans that American nutrition experts recommend. And other diets have some of the same recommendations as the Mediterranean diet.

Understanding the Mediterranean Diet

There's no single definition for the diet, partly because there’s variation between countries. Overall, however, the diet is high in healthy plant foods, is low in animal products and meat and includes fish and seafood at least twice a week. The foundation of the Mediterranean diet is plant foods.

Moderate amounts of dairy, poultry and eggs are part of the Mediterranean diet, as is seafood. Unsaturated fats are a strength of the Mediterranean diet. Olive oil and nuts are the main sources of fat in the Mediterranean diet. They provide unsaturated fat.

Core Components of the Mediterranean Diet

The Mediterranean diet generally involves eating whole foods, such as fruits and vegetables, whole grains, and lean protein, while limiting processed foods. It emphasizes plant-based foods, including whole grains, beans, nuts, and extra-virgin olive oil. Popular in regions like Greece, Italy, Spain and Turkey, the traditional diet features a modest amount of lean poultry and plenty of seafood, focusing on overall diet quality rather than specific nutrients.

Here's a breakdown of the key food groups:

Vegetables: Tomatoes, broccoli, kale, spinach, onions, cauliflower, carrots, Brussels sprouts, cucumbers, potatoes, sweet potatoes, turnips.
Fruits: Apples, bananas, oranges, pears, strawberries, grapes, dates, figs, melons, peaches. Aim for 2 to 3 servings of fruit each day.
Whole Grains: Oats, brown rice, rye, barley, corn, buckwheat, whole wheat bread and pasta. Switch to whole-grain bread, cereal and pasta. You also can try other whole grains, such as bulgur, barley and farro. If you eat about 2,000 calories a day, aim to have at least 3 ounces of whole grains.
Legumes: Beans, peas, lentils, pulses, peanuts, chickpeas. Eat at least three servings a week of legumes.
Nuts and Seeds: Almonds, walnuts, macadamia nuts, hazelnuts, cashews, sunflower seeds, pumpkin seeds, almond butter, peanut butter. Each week, aim to eat four servings of raw, unsalted nuts.
Herbs, Spices, and Condiments: Sea salt, pepper, turmeric, cinnamon, cayenne pepper, oregano, garlic, basil, mint, rosemary, sage, nutmeg, cinnamon, pepper. Spice it up. The Mediterranean diet has a lot of flexibility, so you can make it a delicious and nutritious way to eat.
Fish and Seafood: Salmon, sardines, trout, tuna, mackerel, shrimp, oysters, clams, crab, mussels. Eat fish or shellfish 2 to 3 times a week. Fresh or water-packed tuna, salmon, trout, mackerel and herring are healthy choices.
Poultry: Chicken, duck, turkey.
Eggs: Chicken, quail, and duck eggs.
Dairy: Cheese, yogurt, milk. Some good choices are skim or 1% milk, low-fat cottage cheese, and low-fat Greek or plain yogurt. Limit how much cheese you eat. One serving is about the size of four dice. And cut back on higher fat dairy.
Healthy Fats: Extra virgin olive oil, olives, avocados, and avocado oil. Replacing saturated fats with unsaturated fats may help lower the risk of heart disease. For example, you could replace butter with olive, canola, or safflower or sunflower oil in cooking or at the table.

Fats and the Mediterranean Diet

Unsaturated fats are a strength of the Mediterranean diet. Olive oil and nuts are the main sources of fat in the Mediterranean diet, providing unsaturated fat. Fish is also a key part of this diet, especially fatty fish rich in omega-3s.

Omega-3s are unsaturated fats that may lower inflammation, reduce blood fats called triglycerides, and affect blood clotting. Lean fish and shellfish, such as shrimp, crab, clams and scallops, are also included. Choose fish that are low in mercury to avoid potential harm to the brain and nervous system over time.

Alcohol Consumption

Like people all over the world, some who live in the Mediterranean region drink alcohol and some do not. Red wine tends to be included more often than is white wine. Alcohol has been linked with a lower risk of heart disease in some studies. However, it's not risk-free. One large study suggested that people who regularly drank any amount of alcohol had a higher risk of high blood pressure and coronary artery disease.

Factors that affect your decision might be the extra calories alcohol brings to the diet, or any kidney or liver problems you may have. If you do drink, do so in moderation. One serving per day for females and two servings per day for males.

Foods to Limit

While the Mediterranean diet is not highly restrictive, it's important to limit certain foods:

Slowing the decline of brain function as you age.
Helping you live longer.

The Importance of Variety

There’s usually no need to count calories or track macronutrients (protein, fat, and carbs) on the Mediterranean diet, unless you are managing your glucose levels. But, it is essential to consume all food in moderation.

Tips and Advice for Following the Mediterranean Diet

Eat MORE plant-based foods (daily) - Vegetables, whole grains, beans, legumes, herbs, and good extra virgin olive oil.
Eat SOME seafood and omega-3-rich foods (2 to 3 times per week) - Fish (preferably fatty fish like salmon and mackerel, but you can use white fish varieties as well), nuts, and seeds.
Eat LESS red meats and sweets. These should be enjoyed sparingly. And it’s important to remember that it is not just about the frequency but also the amount. When the craving hits for those baked meatballs or rack of lamb, we eat them, but the plate is still a lot more vegetable-focused.
Switch from whatever fats you use now to extra virgin olive oil. Start by using olive oil in cooking, and then try some new salad dressings with olive oil as the base.
Add whole-grain bread or other whole grains to the meal. Select dense, chewy, country-style loaves without added sugar or butter.
Begin or end each meal with a salad.
Add more and different vegetables to the menu. Add an extra serving of vegetables to both lunch and dinner, aiming for three to four servings a day.
Eat more fish, aiming for two to three servings a week.
Substitute wine in moderation for other alcoholic beverages.
Cut out sugary beverages.
Eat less high-fat, high-sugar desserts. Poached or fresh fruit is best. Aim for three servings of fresh fruit a day.
Seek out the best quality food available.
Finally, try to have dinner as a family as often as possible.
