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.
