Policies that emphasize, regulate, and incentivize preventative and preemptive health care tend to reduce health inequalities and increase general health. For example, health insurance policies that incentivize health screenings, annual physicals, and vaccinations encourage individuals to be proactive regarding their health care. Universal access to healthy foods also reduces health inequalities. In particular, social programs such as low-cost community grocery stores and food support programs often drastically reduce health disparities between communities. Social awareness programs emphasizing healthy eating habits and strong fitness habits can also influence individuals' personal health habits.
