今集將會解答有關人類五種味覺的問題。「為何糖份是甜的?」原來是一個錯誤的問題。「為何糖份對人類來說是甜的?」才是正確問法。味道其實不算是真實存在,只是人類大腦創造出來的一種感覺,是人類為了生存而發展出來的探測工具,讓我們可以分辨哪種食物有營養價值、哪一種有毒。

This episode covers the five taste receptors which are sweet, salty, spicy, bitter, and sour. "Why is sugar sweet?" is the wrong question. "Why does sugar taste sweet to us?" is the right question. Taste doesn't exist in things. It is something our brains create. It is a type of antenna that mankind has developed for survival. It is the ability to consume nutrients and avoid poison.
