African Americans experience _______, which tends to increase blood pressure.​

A) ​a diet higher in salt than European Americans
B) ​a diet lower in fat and higher in fiber
C) ​larger and more cohesive families
D) ​discrimination based on skin color

Discrimination based on skin color is a known risk factor for increased blood pressure among African Americans. This can be attributed to the chronic stress and trauma associated with experiencing discrimination, which leads to increased physiological responses and eventually hypertension. While there may be differences in diet and family structure between African Americans and European Americans, they are not directly linked to increased blood pressure.
