Naturally Gluten-Free Staples of the Mediterranean Diet

Many of the most celebrated foods in Mediterranean cuisine are inherently gluten-free. Building your meals around these foundational ingredients ensures a nutritious and delicious diet.

Fruits and Vegetables

As the base of the Mediterranean food pyramid, a wide variety of fresh, local, and seasonal fruits and vegetables should be eaten at every meal.

Vegetables: Tomatoes, cucumbers, spinach, kale, cauliflower, broccoli, bell peppers, eggplant, and zucchini are all excellent choices.
Fruits: Enjoy berries, apples, oranges, pears, figs, and grapes, which provide essential vitamins, minerals, and antioxidants.
Avocados: A cornerstone of healthy fats, avocados can be added to salads or used in spreads.

Legumes

Lentils, chickpeas, and beans are fantastic sources of plant-based protein and fiber, central to many Mediterranean meals.

Chickpeas: Essential for making hummus and falafel. Ensure falafel is prepared using a gluten-free binder or method.
Lentils: Perfect for hearty soups and stews.
Beans: Including cannellini, fava, and kidney beans, are great in salads and stews.

Healthy Fats

Extra virgin olive oil is the primary fat source, prized for its flavor and anti-inflammatory properties. Nuts and seeds are also key sources of healthy fats, fiber, and protein.

Nuts: Almonds, walnuts, and pistachios are perfect for snacking or adding to dishes.
Seeds: Sunflower and sesame seeds (and tahini) are commonly used.

Protein Sources

Fish and seafood are encouraged at least twice a week, while poultry and eggs are consumed in moderation.

Fish and Seafood: Examples include salmon, sardines, trout, tuna, shrimp, and mussels. Baked or grilled preparations are ideal; avoid breaded versions.
Poultry and Eggs: Good protein sources, but should be consumed less frequently than plant-based proteins and seafood.

Dairy and Herbs

Dairy: Greek yogurt, goat cheese, and feta are typically gluten-free options. Fermented dairy can benefit gut health, but always check labels for additives.
Herbs and Spices: Naturally gluten-free, these add authentic flavor without needing extra salt. Popular choices include oregano, basil, parsley, mint, rosemary, and thyme.
