Potential Health Concerns and How to Address Them

Conclusion: The Verdict on Healthy Pesto

Whether pesto is healthy depends on quality and quantity. The beneficial ingredients in traditional pesto offer antioxidants and healthy fats.

Choosing homemade or high-quality store-bought pesto and using it sparingly allows you to enjoy its flavor in a balanced diet.

Pro Tip for Homemade Pesto
