The term "healthier version" refers to a modified or altered form of something that is considered to be better for one's health compared to its original counterpart. This could mean that it contains fewer calories, less sugar, fat or salt, more nutrients and vitamins, or has been made with healthier ingredients overall. The phrase can be used in a variety of contexts such as food, drinks, fitness routines, lifestyle choices, etc., to describe something that is an improvement over the traditional version due to its positive impact on one's well-being.
