'high-protein' originates from the combination of 'high,' meaning 'great in amount or degree,' and 'protein,' which comes from the Greek word 'proteios,' meaning 'primary' or 'of first importance.'

'protein' changed from the Greek word 'proteios' to the modern English word 'protein' through Latin and French influences.

Initially, 'protein' referred to a primary substance in nutrition, and this meaning has largely remained the same in modern usage.
