SAMA HOOLE: Your tongue has 25 receptors for bitter. Twenty-five. One for every family of plant poison your ancestors learned to spit out, because bitter is the taste of a leaf defending itself.

Your tongue has a receptor for meat. It detects glutamate and inosinate, the taste of a steak, a broth and an aged cheese, and it rewards you for finding them.

Your tongue has a receptor for fat. Found in 2015, named oleogustus, and it fires on dripping, marrow and cream.

Your tongue has a receptor for meat. It detects glutamate and inosinate, the taste of a steak, a broth and an aged cheese, and it rewards you for finding them. Your tongue has a receptor for fat. Found in 2015, named oleogustus, and it fires on dripping, marrow and cream. Your tongue has one receptor for sweet. It was built for ripe fruit and honey, which arrived for a few weeks a year. Your tongue has 25 receptors for bitter. Twenty-five. One for every family of plant poison your ancestors learned to spit out, because bitter is the taste of a leaf defending itself. Every child on earth rejects greens without being taught. That is the 25 receptors working exactly as built. The adult learns to override them. It takes years, salt, oil and a sauce, and the child is told it is being difficult. One receptor for meat, one for fat, 25 alarms for plants, and the whole nation has been trained to eat past the alarms and feel guilty about the two that say yes.

Your tongue filed broccoli under poison before you had a word for either.
