Pesto, a vibrant green sauce originating from Genoa, Italy, is celebrated not only for its distinctive flavor but also for its array of nutritional benefits. Traditionally crafted by crushing fresh basil, garlic, pine nuts, Parmesan cheese, and extra virgin olive oil with a mortar and pestle, pesto adds a burst of summer flavor to a variety of dishes. Understanding its nutritional profile and health benefits can help you make informed choices about incorporating it into your diet.
What is Pesto?
The term "pesto" is a generic descriptor for any uncooked sauce created by crushing or grinding ingredients into a paste. Its roots trace back to Genoa, Italy, where "pestare" means "to pound or crush," reflecting the traditional preparation method. While basil pesto (pesto Genovese) remains the most recognizable, variations abound, offering a diverse palette of flavors and nutritional profiles.
Traditional Pesto Ingredients
Classic pesto, or pesto Genovese, typically includes:
- Fresh basil
- Fresh garlic
- Salt
- Extra-virgin olive oil
- Aged Parmesan and/or Pecorino cheese
- Pine nuts
These simple ingredients combine to create a versatile condiment that can be used as a sauce for pasta, a spread for sandwiches, a marinade for meats, or a flavorful addition to soups and salads.

These values highlight the nutritional benefits of pesto, particularly its healthy fats and protein content.
Macronutrients
- Fats: Fats are a significant component of basil pesto, primarily from olive oil and nuts. A serving of basil pesto contains approximately 8-10 grams of fat, including healthy monounsaturated and polyunsaturated fats. The fat content in pesto is primarily unsaturated, which is believed to have heart health benefits. Mono- and polyunsaturated fats from plants and nuts can block the production of inflammation-promoting compounds in your body. Plus, eating more of these foods may improve blood pressure, blood sugar, and cholesterol levels
- Proteins: Although not a primary source of protein, basil pesto provides a modest amount of this essential macronutrient. A serving contains about 2-3 grams of protein, which comes mainly from the cheese and nuts. Pine nuts are a healthy, plant-based source of protein.
- Carbohydrates: Basil pesto is low in carbohydrates, making it suitable for low-carb diets. A typical serving contains only about 1-2 grams of carbohydrates, primarily from the basil leaves and garlic.
Vitamins and Minerals
In addition to macronutrients, basil pesto is rich in various vitamins and minerals that contribute to its health benefits. Basil pesto is an excellent source of vitamin A, which is essential for maintaining healthy vision, supporting immune function, and promoting cell growth. Vitamin C, known for its immune-boosting properties, is also present in basil pesto. Iron is a crucial mineral for producing hemoglobin, a protein in red blood cells that carries oxygen throughout the body. Calcium is essential for maintaining strong bones and teeth, as well as for muscle function and nerve transmission.
Health Benefits of Pesto
The ingredients in pesto contain an array of nutrients that are good for your mind and body. Pesto is a nutrient-rich, flavorful sauce packed with healthy fats, antioxidants, and vitamins. The health benefits of basil pesto go beyond its nutrient content.
Antioxidant Properties
Basil pesto is rich in antioxidants, which help combat oxidative stress in the body. Oxidative stress occurs when there’s an imbalance between free radicals and antioxidants, leading to cell damage and contributing to various chronic diseases. Antioxidants can help protect your cells and DNA from oxidative damage. Sweet basil contains multiple antioxidant molecules that may help fight cellular damage, decrease inflammation, and reduce your risk of chronic health conditions.
Anti-Inflammatory Effects
Chronic inflammation is linked to numerous health conditions, including heart disease, arthritis, and certain cancers. Basil pesto contains ingredients with anti-inflammatory properties, such as basil, olive oil, and nuts. Healthy fats, antioxidants, and other compounds in olive oil and pine nuts can block the production of inflammation-promoting compounds in your body.

Heart Health
One of the most notable benefits of basil pesto is its positive impact on heart health. Olive oil, a key ingredient in basil pesto, is well-known for its heart health benefits. It is rich in monounsaturated fats, which help lower bad cholesterol (LDL) levels while maintaining good cholesterol (HDL) levels. Nuts, such as pine nuts, walnuts, or almonds, are another crucial component of basil pesto that contribute to heart health. These nuts provide healthy fats, protein, and fiber, all of which are beneficial for maintaining cardiovascular health.
Digestive Health
Pesto promotes digestive health from garlic, which has prebiotic properties and supports a healthy gut microbiome.
Part of the Mediterranean Diet
Pesto is part of the Mediterranean diet. This eating pattern often includes fresh herbs, olive oil, and nuts - some of the ingredients in pesto - and is linked with a lower risk of many chronic health conditions, especially:
- heart disease, heart attack, and stroke
- diabetes
- many types of cancer, including breast, stomach, pancreatic, and liver
- Alzheimer’s disease and dementia
Benefits of Individual Ingredients
- Olive Oil: Olive oil contains a lot of healthy fats that may reduce your risk of heart disease. Some research has even found that people who eat high levels of olive oil are 81% more likely to live longer! Lab studies on olive oil also show it can prevent the growth of bacteria, other microbes, and maybe even certain tumors.
- Garlic: Garlic may help your immune system work more efficiently, reducing inflammation while helping your body better fight off infection. It can also keep you healthy by reducing blood pressure levels. Garlic’s plant compounds have been shown to lower blood pressure and cholesterol. Like olive oil, garlic has antimicrobial properties. Plus, some animal and test-tube studies suggest that certain compounds in garlic might stop the growth of or even kill cancer cells.
- Basil: Fresh basil is also associated with health benefits. For example, test-tube and animal studies have shown that antioxidants and essential oils from basil leaves may reduce blood sugar levels and prevent the growth of foodborne pathogens
Potential Health Risks
While pesto offers numerous health benefits, it’s important to be aware of potential allergens and health risks that could affect some individuals.
High Fat and Calorie Content
Pesto has a high fat content due to ingredients like olive oil, nuts, and cheese, which can raise cholesterol levels and increase the risk of heart disease when consumed in large quantities. High calorie content can contribute to weight gain if consumed frequently or in large portions, especially when paired with high-calorie foods like pasta.

High Sodium Content
High sodium content particularly in commercial varieties, which can contribute to hypertension and increased cardiovascular risks.
Allergens
Basil pesto contains several ingredients that are common allergens, including nuts and dairy. Pine nuts, often used in traditional pesto recipes, can cause allergic reactions in individuals with nut allergies. Accidentally eating pesto that contains nuts could trigger a life threatening anaphylactic reaction in those who are allergic to tree nuts.
Foodborne Illness
Another potential concern about eating pesto is the risk of foodborne illness. Like other fresh foods, fresh pesto - whether homemade or from the refrigerator section at the grocery store - can spoil if not stored properly or stored too long.
How to Choose and Store Pesto
Choosing Quality Pesto
Quality pesto should have a vibrant green color and a fresh, herbaceous aroma, indicating it is made with fresh basil. The texture should be creamy but with some granularity to show it hasn't been overly processed. The oil should be well-emulsified with the other ingredients. Avoid pesto that has separated, with oil pooling on the surface, or has turned a darker green or brown color, as these changes can suggest oxidation or age. Pesto that smells sour or rancid should also be avoided, as it will negatively impact its flavor.
Storage Tips
Pesto should be kept in the refrigerator in a sealed container. Keeping it chilled helps preserve its taste and prevents it from spoiling for 1-2 weeks after opening. To maintain its bright green hue, consider adding a thin layer of olive oil on the surface. When pesto is exposed to air, it can oxidize and diminish in quality. Make sure to keep it covered and avoid using unclean utensils, as this can introduce harmful bacteria. Always use a clean spoon to take out the amount you need and promptly close the container afterward. Extra Tip: To preserve pesto for longer periods, consider freezing it in ice cube trays, allowing you to thaw small portions as needed without exposing the entire batch to air.
Shelf Life
Pesto can last for 1-2 weeks in the refrigerator once opened. For longer storage, pesto can be frozen for up to 6 months. Ensure it is stored in an airtight container to maintain its flavor and quality. Unlike fresh pesto, the type sold on unrefrigerated shelves has been pasteurized and/or contains preserving ingredients. When it’s unopened, you can keep it in your pantry - just make sure to store it in the fridge after opening it and use it within about 2 weeks.
Creative Uses for Leftover Pesto
Leftover pesto can be used in a variety of flavorful dishes. Toss it with pasta for a quick and easy meal, or spread it on sandwiches, wraps, or pizzas for a burst of herby flavor. Pesto is also great when mixed into a vinaigrette for salads, adding a fresh and aromatic touch. Use pesto as a marinade for grilled meats, fish, or vegetables, where its flavors infuse the ingredients as they cook. If you have a lot of pesto, consider making a batch of pesto butter by mixing it with softened butter, perfect for spreading on bread or topping grilled dishes. Pesto can also be stirred into a risotto or quinoa for added richness or used as a dipping sauce for breadsticks, vegetables, or shrimp.
Variations and Alternatives
While traditional basil pesto is the most well-known, there are many variations of pesto sauces.
Nut-Free Alternatives
For individuals with allergies, there are several alternatives to the traditional ingredients used in basil pesto. For a nut-free version, you can substitute pine nuts with seeds such as sunflower or pumpkin seeds. These seeds provide a similar texture and nutty flavor without the allergenic properties.
Dairy-Free Options
For a dairy-free option, you can use nutritional yeast in place of Parmesan cheese.
Other Greens
Purists may argue that real pesto should be made from basil. But if you don’t care for basil or don’t have any on hand, there’s no reason you can’t make pesto from other ingredients. Any fresh, flavorful herbs or leafy greens can stand in for basil.
Other greens to include in your pesto:
- spinach
- arugula
- baby kale
- oregano
- parsley
- cilantro
If you want to get creative, you can also make pesto from sun-dried tomatoes, olives, or roasted red peppers.
