Dietary diversity، or eating a wide range of foods، is perceived by most people to be beneficial for their health. However، it might actually backfire، as the Technical Times said. According to the American Heart Association's latest scientific statement، a diverse diet، otherwise called a "varied diet،" could just lead to eating more calories، which in turn increases risks of obesity. The problem doesn't lie in the diet itself — people might just be misinterpreting what "varied" really means in the context of a healthy diet. Marcia C. de Oliveira Otto، lead author of the latest advisory، says that could be a big problem. "We looked at all the evidence that was out there and saw a link between dietary diversity and a greater intake of both healthy and unhealthy foods،" according to Otto، an assistant professor of at the University of Texas's Department of Epidemiology، Human Genetics and Environmental Sciences. "This raised some red flags and had implications on obesity — we saw a greater prevalence of obesity amongst people with a greater dietary diversity." While some dietary guidelines prioritize having varied diets، majority are unclear about what so-called dietary diversity is، exactly. Also unclear is how such a diet is measured and whether it is a healthy dietary goal.
