'health-conscious' originates from the combination of 'health' and 'conscious,' where 'health' refers to the state of being free from illness or injury, and 'conscious' means being aware of and responding to one's surroundings.

'health-conscious' evolved from the increasing awareness and importance of personal health and wellness in modern society.

Initially, it meant being aware of one's health, and this meaning has largely remained the same in modern usage.
