Understanding the Mediterranean Diet Principles
The Mediterranean diet isn't a restrictive set of rules but a flexible eating pattern inspired by the traditional cuisines of countries bordering the Mediterranean Sea, such as Greece and Italy. It emphasizes enjoying meals with family and friends and prioritizing fresh, whole foods over processed ones.
The Foundation: Plant-Based Foods and Healthy Fats
At its core, the diet is built on a foundation of plant-based foods. This includes consuming plenty of fresh and seasonal vegetables, fruits, legumes, nuts, seeds, and whole grains. The primary source of added fat is extra virgin olive oil, which is rich in monounsaturated fats and antioxidants.
The Role of Protein
Protein sources are consumed in moderation and vary widely. Fish and seafood are eaten frequently, often at least twice a week. Lean poultry and eggs are included weekly, while red meat and highly processed meats are limited to only a few times per month.
A Typical Daily Mediterranean Diet Example
Breakfast: A bowl of Greek yogurt topped with fresh berries, a handful of walnuts, and a drizzle of honey. Another option might be avocado toast on whole-grain bread with sliced tomatoes and a sprinkle of black pepper.
Lunch: A large Greek salad with mixed greens, cucumber, cherry tomatoes, kalamata olives, and a small amount of feta cheese, all dressed with extra virgin olive oil and lemon juice. Add a scoop of quinoa or chickpeas for extra protein and fiber.
Dinner: Grilled salmon seasoned with herbs like rosemary and lemon, served with a side of roasted vegetables such as zucchini, eggplant, and bell peppers, and a small portion of brown rice.
Snacks: Healthy snacks can include a handful of almonds, an apple with a tablespoon of almond butter, or some raw veggies with hummus.
