Why are health studies so white?

As a single mother of an asthmatic son in Memphis, Tennessee, Peete worked hard to provide her child with the medical care he needed. Her son took medications, received allergy shots, and used a nebulizer, a machine that pumps vaporized medicine into the lungs. Despite her efforts, her son may have received treatments tailored to someone else. As with many diseases, the bulk of research on respiratory ailments in the U.S. has focused on white European-Americans, and Peete and her son are black.
