Humans detect taste with taste receptor cells. These are clustered in taste buds and scattered in other areas of the body. Each taste bud has a pore that opens out to the surface of the tongue enabling molecules and ions taken into the mouth to reach the receptor cells inside.

Why do we not like some foods?

One biological mechanism for why we perceive tastes differently is in our taste buds. … Super tasters are those who have more “fungiform papillae” taste receptors, and can taste certain things like bitterness more intensely.

These receptor cells are sensitive to the chemicals contained within foods that are ingested, and they release neurotransmitters based on the amount of the chemical in the food.

How does taste help us survive?

The sense of taste is our body’s gatekeeper, promoting our species’ survival by encouraging us to eat things that we need and avoid those that could harm us. Like many other animals, our early ancestors evolved an aversion to bitter flavours, helping to evade plant toxins.
