Our taste buds are naturally wired for a preference for sweet. When combined with salt and fat, our taste buds are not only happy but so is our brain. And while there is nothing wrong with a happy brain, our taste buds have been hijacked to respond positively to sweet and salty at the expense of bitter. If you don't believe me, think about the last time you ate radicchio, dandelion, chicory, or bitter melon.
These bitter foods that are part of traditional global cuisines are essentially absent from most people's modern diet. This lack of bitterness in our daily diet may explain why we are seeing so many digestive system issues.
Bitter taste is associated with activating the digestive system. Bitter engages and excites the digestive process essentially calling it to wake up and prepare for incoming food. In this way bitter flavors are essential to health.
Here are some interesting ways to incorporate bitterness into your daily diet. At first your taste buds might be surprised by the bitter taste, but taste buds have the ability to evolve and change over time, so soon you could be seeking the bitter flavor out.
