Pesto, that vibrant green sauce originating from Genoa, Italy, is a culinary staple adored worldwide. Its rich, herbaceous flavor elevates pasta dishes, sandwiches, salads, and more. However, not all pesto is created equal. While the classic recipe boasts fresh ingredients, commercial versions can sometimes be laden with unhealthy additives, excess salt, and lower-quality oils. So, what is the healthiest pesto to buy? This guide explores the nutritional landscape of pesto, helping you make informed choices for a healthier and tastier experience.
Understanding the Basics of Pesto
Traditional pesto, or “pesto alla Genovese,” typically consists of seven core ingredients: fresh basil, pine nuts, garlic, Parmesan cheese, Pecorino cheese, extra virgin olive oil, and salt. These ingredients, when high quality, offer numerous health benefits.
Basil is rich in antioxidants and vitamins. Pine nuts contribute healthy fats and minerals. Garlic is known for its immune-boosting properties. Parmesan and Pecorino provide calcium and protein. Extra virgin olive oil delivers heart-healthy monounsaturated fats.
However, the convenience of store-bought pesto often comes at a cost. Manufacturers may substitute ingredients or add preservatives to extend shelf life and reduce production costs. These alterations can significantly impact the nutritional profile and overall healthfulness of the product.
Key Ingredients to Watch Out For
When selecting a healthy pesto, scrutinizing the ingredient list is paramount. Certain ingredients should raise red flags.
Sunflower Oil as a Substitute
Many commercial pesto brands replace extra virgin olive oil with sunflower oil or other cheaper vegetable oils. While sunflower oil isn’t inherently unhealthy, it lacks the same beneficial antioxidants and monounsaturated fats as extra virgin olive oil. Extra virgin olive oil also contributes to the unique flavor profile of authentic pesto. Opt for pestos that prominently feature extra virgin olive oil as the primary oil source.
Excessive Salt Content
Salt is a crucial component of pesto, enhancing the flavors of the other ingredients. However, many store-bought pestos contain excessive amounts of sodium, which can contribute to high blood pressure and other health problems. Check the nutrition facts label and compare sodium content across different brands. Choose options with lower sodium levels.
Hidden Sugars and Additives
Some pesto brands may add sugar to balance the acidity or artificial preservatives to prolong shelf life. These additions can diminish the health benefits of the sauce and may be detrimental to your overall health. Scrutinize the ingredient list for added sugars like dextrose, corn syrup, or artificial preservatives such as potassium sorbate or sodium benzoate.
Lower-Quality Cheese
The type of cheese used in pesto significantly impacts its flavor and nutritional value. Authentic pesto uses high-quality Parmesan and Pecorino cheeses, which are aged and full of flavor. Some commercial brands may substitute these with lower-quality cheeses or cheese powders, which lack the same depth of flavor and nutritional benefits. Look for pestos that specify the use of real Parmesan and Pecorino cheese.
Modified Starches and Fillers
Some manufacturers use modified starches or fillers to thicken the pesto or reduce the amount of expensive ingredients like basil and pine nuts. These additives offer little to no nutritional value and can detract from the overall quality of the product.
Decoding the Nutrition Facts Label
Understanding the nutrition facts label is essential for making informed decisions about the healthiest pesto to buy. Pay close attention to the following aspects:
Serving Size
Always check the serving size to accurately assess the nutritional content. What may seem like a reasonable amount of calories, fat, or sodium could be significantly higher per serving than you realize.
Total Fat and Saturated Fat
Pesto is naturally high in fat due to the olive oil and nuts. However, focus on the type of fat. Aim for pestos that are predominantly composed of monounsaturated fats from extra virgin olive oil. Limit your intake of saturated fat.
Sodium Content
As previously mentioned, sodium content is a crucial factor to consider. Compare sodium levels across different brands and choose options with lower amounts. Aim for pestos that contain less than 200mg of sodium per serving.
Sugar Content
Ideally, pesto should have minimal to no added sugar. Check the ingredient list for added sugars and choose options that are naturally sweet from the basil and other ingredients.
Protein and Fiber
While pesto isn’t typically a significant source of protein or fiber, some brands may contain higher amounts due to the inclusion of nuts and cheese. These nutrients can contribute to satiety and overall health.
Healthiest Pesto Buying Strategies
Navigating the pesto aisle can be overwhelming. Here are some strategies to help you choose the healthiest option:
Read the Ingredient List Carefully
This is the most crucial step. Prioritize pestos with short, recognizable ingredient lists. The ingredients should primarily consist of fresh basil, extra virgin olive oil, pine nuts, garlic, Parmesan cheese, Pecorino cheese, and salt. Avoid products with added sugars, artificial preservatives, or low-quality oils.
Opt for Refrigerated Pesto
Refrigerated pesto is often fresher and contains fewer preservatives than shelf-stable versions. It’s more likely to be made with higher-quality ingredients.
Consider Organic Options
Organic pesto is made with ingredients grown without synthetic pesticides or fertilizers. This can reduce your exposure to harmful chemicals and support sustainable farming practices.
Check the Sodium Content
Compare sodium levels across different brands and choose options with lower amounts.
Look for Extra Virgin Olive Oil
Ensure that extra virgin olive oil is the primary oil source. This provides the most health benefits and contributes to the authentic flavor of pesto.
Support Local Producers
If possible, consider purchasing pesto from local farmers markets or specialty food stores. These producers often use fresh, high-quality ingredients and may offer unique flavor variations.
Making Your Own Healthy Pesto
The best way to ensure you’re consuming the healthiest pesto is to make it yourself. Homemade pesto allows you to control the ingredients and adjust the recipe to your preferences. Here’s a basic recipe:

When in doubt, making your own pesto at home is always the best option, allowing you to control every ingredient and create a sauce that perfectly aligns with your dietary needs and preferences.
What makes one pesto healthier than another?
The healthiness of pesto primarily boils down to its ingredients and their proportions. Traditional pesto is made with basil, pine nuts, Parmesan cheese, garlic, and olive oil, but commercially produced versions can vary significantly. Healthier pestos often prioritize a higher basil content, use extra virgin olive oil, and minimize the amount of cheese and salt. The presence of added sugars, unhealthy oils (like sunflower or canola oil), or artificial preservatives can detract from the overall health profile.
Furthermore, nut sources and their quality impact nutritional value. Pine nuts, while traditional, can be expensive; some manufacturers substitute with cheaper alternatives like walnuts or cashews. While these substitutes are not inherently unhealthy, they alter the flavor profile and nutritional composition, potentially increasing the omega-6 to omega-3 fatty acid ratio, which ideally should be balanced. Paying attention to these ingredient details helps determine the overall healthfulness of a pesto.
What are the benefits of choosing pesto made with extra virgin olive oil?
Extra virgin olive oil (EVOO) is a cornerstone of the Mediterranean diet and offers numerous health benefits. Unlike refined olive oils, EVOO is extracted through cold pressing, which preserves its natural antioxidants, including polyphenols. These antioxidants have anti-inflammatory properties and can protect against chronic diseases such as heart disease and cancer. Using EVOO in pesto contributes significantly to the pesto’s overall nutritional value.
EVOO also boasts a rich, fruity flavor that enhances the taste of pesto. Its monounsaturated fats, primarily oleic acid, contribute to heart health by helping to lower LDL (bad) cholesterol levels. In contrast, pestos made with less healthy oils like sunflower or canola oil may contribute to inflammation due to their higher omega-6 fatty acid content and lack the beneficial antioxidants found in EVOO.
Are there healthier alternatives to Parmesan cheese in pesto?
While Parmesan cheese adds a distinct flavor and texture to pesto, it is high in saturated fat and sodium. Healthier alternatives focus on lower-sodium and lower-fat options. Nutritional yeast can be used to impart a cheesy flavor with fewer calories, fat, and sodium. It is also a good source of B vitamins, making it a beneficial addition for vegans and vegetarians.
Another approach is to reduce the quantity of Parmesan used and supplement with other flavor enhancers like lemon juice or a touch more garlic. Some recipes incorporate a small amount of Pecorino Romano cheese, which has a sharper flavor, allowing for a smaller quantity to achieve a similar taste impact. Ultimately, moderation and mindful substitution can contribute to a healthier pesto without sacrificing flavor.
How can I identify pesto with a lower sodium content?
Reading the nutrition label is crucial for identifying pesto with a lower sodium content. Pay close attention to the “sodium” listing per serving and compare different brands. Look for products labeled “low sodium” or “reduced sodium,” which generally contain significantly less sodium than regular versions. Consider the serving size provided on the label, as this can be misleading if it doesn’t reflect a typical serving.
Another strategy is to check the ingredient list for added salt. Some manufacturers use excessive amounts of salt to enhance flavor or extend shelf life. Choosing pestos with minimal or no added salt allows you to control the sodium content when you use it in your recipes. Making your own pesto at home is the best way to completely control the ingredients, including the amount of salt.
What are the benefits of making my own pesto compared to buying it?
Making your own pesto offers significant advantages in terms of health and quality control. When you make it yourself, you have complete control over the ingredients, allowing you to choose high-quality, fresh components like organic basil, extra virgin olive oil, and freshly grated Parmesan cheese. This ensures that you are consuming the best possible nutrients and avoiding unhealthy additives or preservatives.
Homemade pesto allows for customization to suit your dietary needs and preferences. You can easily adjust the amount of cheese, garlic, or olive oil to create a pesto that aligns with your health goals. Furthermore, you can experiment with different nut varieties or incorporate other healthy additions like spinach or kale to boost the nutritional value. Ultimately, making your own pesto provides a fresher, healthier, and more personalized culinary experience.
What are some healthy additions I can incorporate into pesto to boost its nutritional profile?
Beyond the traditional ingredients, there are several ways to enhance the nutritional profile of pesto. Adding leafy greens like spinach, kale, or arugula not only increases the vitamin and mineral content but also provides added fiber. These greens blend seamlessly into the pesto, offering a subtle flavor boost and a significant nutritional advantage. Flaxseeds or chia seeds can be incorporated for an added dose of omega-3 fatty acids and fiber.
Consider adding roasted vegetables like bell peppers or sun-dried tomatoes to enhance the flavor and nutrient content. These additions provide antioxidants and vitamins while adding depth to the pesto’s flavor profile. A squeeze of lemon juice can brighten the flavors and provide a boost of vitamin C. These simple additions transform pesto into a more nutritionally dense and flavorful condiment.
How should I store pesto to maintain its nutritional benefits and flavor?
Proper storage is essential for preserving the nutritional benefits and flavor of pesto. Store-bought pesto should be refrigerated immediately after opening and consumed within a few days. To prevent oxidation and browning, press a layer of olive oil on top of the pesto before sealing the container. This creates a barrier that protects the pesto from exposure to air.
For longer-term storage, freezing pesto is an excellent option. Portion the pesto into ice cube trays or small freezer-safe containers. Once frozen, transfer the cubes or portions to a freezer bag for convenient use. Thawing only the amount you need helps preserve the freshness and flavor of the remaining pesto. Properly stored pesto can retain its quality for several months in the freezer, ensuring you have a healthy and flavorful ingredient readily available.
