Diet and Prevention of Cardiovascular Disease and Cancer: JACC: CardioOncology State-of-the-Art Review

Abstract

Cardiovascular disease (CVD) and cancer remain the leading causes of mortality in the United States, where poor diet has surpassed smoking as the leading risk factor for death, and life expectancy has hit a plateau as CVD mortality has stagnated over the past decade. Although the pathophysiology of CVD and cancer is complex and multifactorial, lifestyle factors including diet often contribute significantly to their pathogenesis. There is a wealth of observational data as well as emerging trial data supporting the benefits of a predominantly whole-food plant-based diet in the prevention of CVD and cancer. However, there is a need for implementation science to effectuate existing knowledge. Given the shortcomings of the standard American diet, characterized by excessive intake of red meat and ultraprocessed foods, while deficient in fiber and phytonutrients, it will be necessary to shift default patterns of eating to make healthy choices the path of least resistance.
