Which tastes do you like?

Your ability to taste bitter substances protects you from swallowing harmful substances - many poisonous plants taste bitter. But it is possible to 'acquire a taste' for a bitter substance such as the quinine in tonic water, or coffee. An acquired taste popular throughout the world is capsaicin, the substance in chilli peppers that makes them hot. Even though capsaicin triggers pain receptor cells, it's eaten daily by over one-third of the world's population.
