Heredity is considered a non-modifiable risk factor for health because it refers to the genetic predispositions or traits that are inherited from parents. These genetic factors can influence an individual's susceptibility to various health conditions and diseases, such as heart disease, diabetes, and certain types of cancer. Since these traits are established at birth and cannot be changed, they fall under the category of non-modifiable risk factors.

In contrast, unhealthy diet, physical activity level, and tobacco use are all modifiable risk factors. These factors can be changed or improved through lifestyle choices, interventions, and health-promoting behaviors. For instance, individuals can adopt a healthier diet, increase their physical activity, and quit smoking to reduce their overall risk for chronic diseases. Understanding the distinction between modifiable and non-modifiable risk factors is crucial for developing effective health management strategies and interventions.
