Rose and colleagues1 reported intriguing results showing that elevated chocolate intake was found in individuals with probable major depression (as defined by a Center for Epidemiologic Studies Depression Scale [CES-D] score of ≥22), whatever the sex of the individual.
Although one review has already concluded that there is no evidence that chocolate has a significant impact on depression,2 the interrelationship among elevated chocolate intake, depression, and clinical progression of human immunodeficiency virus (HIV) or hepatitis C virus (HCV) may be particularly fascinating in the HIV-HCV–positive population for several reasons. These individuals have a history of drug injection and/or alcohol abuse, which may both be detrimental to HIV treatment adherence and response.
