There are certain foods I can't get enough of and, incidentally, most of them fall within the Italian diet. Luckily for my health, Italian cuisine follows the Mediterranean pattern of eating-it focuses on simple, natural ingredients, such as tomatoes, garlic, olive oil, dark leafy greens and whole grains, making it one of the world's healthiest diets. Research suggests that the benefits of a Mediterranean-style eating pattern may include improved weight loss, better control of blood-glucose (sugar) levels and reduced risk of depression. Check out these 8 essential ingredients of Italian cuisine, compiled by EatingWell's editors, that you should add to your diet.

1. Olive Oil
Make olive oil, which is high in monounsaturated fat, your go-to cooking oil. By replacing butter with olive oil-the most commonly used oil in the Mediterranean-you'll cut back on saturated fat, help lower "bad" LDL cholesterol and boost levels of "good" HDL cholesterol. In addition, extra-virgin olive oil is high in antioxidants called polyphenols that have been linked to heart health. Try eating like an Italian by dressing your salad greens with a drizzle of extra-virgin olive oil and a squeeze of lemon or use olive oil to sauté fresh vegetables. You can even use olive oil in place of some butter in baking.

2. Tomatoes

There's nothing quite like a ripe tomato, whether served on a bed of fresh greens or made into an Italian red sauce to dress a bowl of hearty pasta. Tomatoes are packed with vitamin C and lycopene, a heart-protective antioxidant that may also help prevent some cancers (particularly prostate). Vitamin A, potassium and folate are also among the tomato's nutritional benefits. Although cooked tomatoes have less vitamin C, their lycopene is more available and antioxidant activity is undiminished. To boost the tomatoes in your diet, add fresh tomatoes to your salads, soups or pasta dishes, or learn how to make homemade tomato sauce. Or slice a juicy tomato and enjoy the simple, fresh flavor of tomatoes with a piece of whole-grain toast and a sprinkling of grated Parmesan.

3. Garlic

Garlic has both antibiotic and antifungal properties and boasts anticancer characteristics. Studies show garlic may lower breast, colon, stomach, throat and skin cancer risks. It's heart-healthy, too, as it's been shown to prevent clotting. The secret to all these health benefits? Sulfides. Those beneficial sulfides aren't released, however, unless the garlic is crushed or chopped and left to sit for at least 10 to 15 minutes before eating or cooking. Garlic purchased already chopped offers the same benefits. Try adding chopped garlic to sautéed greens, salad dressings or homemade spaghetti sauce.

4. Seafood

Seafood is a staple protein in Italian diets; any and all kinds of shellfish and fish are celebrated, often several in the same dish. While fattier types like tuna and salmon supply heart-healthy omega-3 fatty acids, lean seafood like shrimp and mussels provide ample protein, niacin and selenium. Serve fish or seafood at least twice a week.

5. Whole Grains

Historically, unrefined grains (whole-wheat pasta, whole-grain bread, barley, whole-wheat couscous) are the base of most Mediterranean diets. Leaving the grains whole lowers their glycemic index, so they are digested more slowly and produce gentler rises in glucose and insulin than refined versions; they also retain all their fiber, magnesium, vitamin E and other antioxidant phytochemicals. Diets rich in whole grains may protect against heart disease, diabetes and other chronic diseases. Top toasted whole-grain bread with diced tomatoes, garlic and basil. Toss whole-wheat pasta with olive oil, garlic and Parmesan cheese.

6. Beans

Beans are an essential, satisfying and healthy ingredient often found in Italian cuisine. Aim to swap out some of your meat and get your protein from beans and other legumes like lentils and chickpeas. By displacing meat, you'll lower your saturated-fat intake while adding healthful nutrients, like fiber and antioxidant-rich flavonols. Eaten daily, combined with grains and starches, beans provide high-quality protein along with folate, calcium, iron and zinc. They also offer healthy, filling doses of fiber (both soluble and insoluble), phytates and phytosterols; studies suggest beans may help manage diabetes, prevent colon cancer and reduce heart disease risk. Add a dish or two that contain beans and other legumes to your weekly menu. Add beans to a hearty pasta dish in place of meat, spread pureed beans on homemade pizza or make a minestrone soup with beans.

7. Nuts

Nut trees are almost as common as olive trees in Italy. Nuts are savored as snacks, ground into sauces and sprinkled on salads. Nuts are loaded with heart-friendly monounsaturated fat; they're also rich sources of protein, fiber, vitamin E, folate, calcium and magnesium. Nut protein is also high in arginine, an amino acid that helps maintain healthy blood vessels. Try topping your salad with chopped nuts or adding nuts to your baking.

8. Dark Leafy Greens

To be Italian is to appreciate dark leafy vegetables, especially this earthily bitter brassica that pairs beautifully with bold ingredients like sausage, anchovy and hot pepper. Like other cabbage family members it's a nutrition superstar, providing plenty of vitamin C, potassium, calcium and fiber as well as carotenoids and cancer-fighting indoles and isothiocyanates. Include a generous portion of rich dark leafy greens, such as chard, kale, escarole and collards, either in a salad or sautéed with olive oil, plenty of garlic and a touch of crushed red pepper.
