ORIGIN

Tidbit originally referred to a small, tasty morsel of food (from the English dialect word "tid," meaning "tender, soft, delicate," plus "bit," meaning "small piece").

It first appeared in English around 1640 in the food sense and by about 1735 was being used to mean "a small, interesting piece of news or information".

Later in the 18th century, tidbit came to be used for anything small or inconsequential.

Here's a tidbit about a tidbit:

Russian composer Igor Stravinsky, who was obsessed with his health, regularly ate only TIDBITS of raw vegetables. While dining with composer Nicholas Nabokov in a restaurant one evening, he ordered raw potatoes and tomatoes. When Nabokov left a slice of cutlet on his plate however, Stravinsky asked if he might finish it off. He did so with a large drop of sour cream and then declared, "I'm going to surprise the raw potato in my stomach!"
