Summary
This pesto contains beneficial ingredients like Genovese basil, extra virgin olive oil, and high-quality cheeses, which contribute to its nutritional value. However, the presence of sunflower oil, a seed oil high in omega-6 fatty acids, detracts from its healthiness due to potential inflammatory effects. The product is processed, which limits its score, despite having a relatively clean ingredient list with minimal additives.
