Dr. Grim, then the director of the hypertension research center at the Charles R. Drew University of Medicine and Science in Los Angeles, hypothesized that high rates of hypertension among African Americans were due to the horrors of slavery, including the Middle Passage, the mass transport of slaves from West Africa to North America from roughly 1600 to 1800. These brutal experiences forced a genetic shift, Dr. Grim argued, that allowed those who were genetically predisposed to retain more sodium in their blood (the definition of hypertension) to survive.
