It's true that wooden cutting boards have antibacterial properties. In fact, studies have shown that they are more effective at reducing bacterial numbers than other cutting board materials like plastic, rubber, and glass. The antibacterial properties of wood come from molecules that are present in the wood, which form a protective barrier against bacteria. Wooden cutting boards also have the added benefit of being a natural renewable resource. So if you're looking for a cutting board that is both healthy and environmentally friendly, then a wooden cutting board is definitely the way to go.
