Slaves Were Well-Fed, Adequately Housed and Received Good Medical Care

The high consumption of meat, sweet potatoes, and peas made the slave diet not only adequate, but it actually exceeded modern recommended daily levels of the chief nutrients. […] Many slaves had far better clothes than poor whites. […] Comments of observers suggest that the most typical slave houses of the late antebellum period were cabins about eighteen by twenty feet. […]
Such housing may sound mean by modern standards but actually compared well with the homes of free workers in the ante bellum era. […]
The medical care was good. Generally, the slaves received the same medical care the family received.
