Why Do Tomatoes Taste So Bland?

The video explores why modern tomatoes often lack flavor, tracing the issue back to artificial selection for uniformly red tomatoes, which inadvertently reduced their sweetness and flavor. This was due to the silencing of the GLK 2 gene, which affects chlorophyll and carotenoid production. Scientists have confirmed this connection and are exploring genetic modifications and traditional breeding methods to restore flavor. Heirloom tomatoes, which retain their GLK 2 gene, are highlighted as a flavorful alternative.

What are heirloom tomatoes, and why are they considered more flavorful?
