Pesto, that vibrant green sauce hailing from Genoa, Italy, is a culinary delight. Its aromatic blend of basil, pine nuts, garlic, Parmesan cheese, and olive oil adds a burst of flavor to pasta, sandwiches, and countless other dishes. But beyond its delicious taste, a crucial question arises: how healthy is pesto, really? Let’s dive into a comprehensive exploration of pesto’s nutritional profile, potential benefits, and possible drawbacks.
Decoding the Ingredients: Pesto’s Nutritional Building Blocks
Pesto’s health value is intricately linked to its core ingredients. Each component contributes unique nutrients and compounds, influencing the overall healthfulness of the sauce.
