- Heavily processed meats (e.g., deli ham, salami, bacon, hot dogs):
These pack high levels of saturated fats, sodium, and preservatives—all of which can work against the heart health you’re aiming for. Stick to roasted chicken breast, grilled turkey, or sustainable fish as your go-to proteins most days. Regional delicacies like Italian prosciutto? Save them for special occasions and enjoy just a small portion when the moment feels right.
- Refined grains (white bread, white rice, many packaged cereals, regular pasta):
Stripped of nutrients and fiber, these cause rapid blood sugar spikes that leave you hungry again fast. Instead, reach for whole-grain breads, brown rice, and traditional grains like farro, bulgur, or barley. When dining out, ask if whole-grain options are available—or simply keep your refined carb portions modest.
- Sugary sweets and desserts (cakes, cookies, candy, soda, packaged pastries):
You won’t find many of these in traditional Mediterranean eating patterns, where fresh fruit or a drizzle of honey over yogurt is the sweet treat of choice. For special occasions, a small portion of your favorite dessert is perfectly fine—just keep those indulgences infrequent. Dark chocolate or a simple fruit compote makes a healthier Mediterranean-style finish to any meal.
- Highly processed snack foods (potato chips, flavored crackers, fried snacks):
Loaded with unhealthy fats and excess salt, these should be swapped for nuts (preferably unsalted), roasted chickpeas, or olives. Craving crunch? Try lightly toasted whole-grain pita brushed with olive oil—it’s satisfying and keeps you in the Mediterranean mindset.
- Butter, margarine, and cream-heavy sauces:
The Mediterranean diet centers on extra virgin olive oil as the main fat source. Use it for cooking or as a finishing drizzle, and swap creamy sauces for blended avocado or Greek yogurt. When a recipe calls for butter, try cutting the amount in half and adding a splash of olive oil for richness.
- Processed cheese and full-fat dairy:
Cheese absolutely has a place in Mediterranean cuisine—but it’s enjoyed in moderation. Skip the processed slices and opt for small amounts of feta, ricotta, or Parmigiano-Reggiano. For daily use, stick with unsweetened yogurt or a splash of milk in your coffee.
- Alcoholic beverages:
Moderate wine consumption may be part of the Mediterranean approach—ideally with meals and limited to one glass daily for women, two for men, following traditional guidelines. Avoid sweetened spirits or heavy cocktails. And if you don’t currently drink, there’s no health reason to start.

Let’s be honest—exceptions are part of the Mediterranean way. Don’t stress if you enjoy a local delicacy or a beloved family recipe during holidays or travel. The real focus is on your overall eating pattern: whole foods, plants, seafood, beans, and olive oil most of the time, with traditional treats appearing just a few times each month.

Who should use caution: risks, contraindications, and medication considerations
The Mediterranean diet is generally heart-healthy and flexible, but it’s not a perfect fit for everyone. Certain health conditions and medications can make aspects of this diet risky—or at least require a few thoughtful modifications.
People with chronic kidney disease (CKD) should proceed carefully. The diet emphasizes legumes, whole grains, and certain fish that are rich in potassium and phosphorus—minerals that can be problematic when kidney function is impaired.
If you have advanced kidney disease, consult your nephrologist before adopting this eating pattern. And if you’re on potassium-sparing diuretics, you’ll need to monitor your intake of high-potassium foods like tomatoes, spinach, and beans to avoid hyperkalemia.

Those with fat malabsorption disorders—such as chronic pancreatitis or certain gallbladder conditions—may struggle with the Mediterranean diet’s emphasis on healthy fats from olive oil, nuts, and fish. Digesting these can lead to gastrointestinal discomfort or nutrient gaps, so careful moderation or low-fat substitutions might be necessary.
Medication-food interactions shouldn’t be overlooked, either. Common Mediterranean foods like grapefruit and some citrus fruits can interfere with statins, antihypertensives, and immunosuppressants, affecting drug absorption or increasing side effects.
Always inform your healthcare provider about all medications and supplements you’re taking to get personalized advice.
Individuals with celiac disease or gluten sensitivity need to sidestep gluten-containing staples commonly found in the Mediterranean diet—like whole-grain breads and couscous. Work with a dietitian to find safe substitutions and prevent gastrointestinal issues.
