A. Establishing a healthy food bank
B. Increasing taxes on tobacco products
Upstream interventions focus on addressing the root causes of health problems and promoting health at the population level. In this context:
A. Establishing a healthy food bank addresses the issue of food insecurity, which is a fundamental determinant of health.
B. Increasing taxes on tobacco products is an example of a policy change aimed at reducing tobacco use, which is a significant risk factor for various health problems.
The other options (C, D, E) are more downstream interventions that involve providing care or education to individuals who are already affected by health issues or at-risk behaviors.
