According to a 2012 report, 2% of the US population follows a vegan diet, which is a strict plant-based diet that excludes all animal-derived foods.1Increasingly, people are choosing to follow this diet for ethical, environmental, religious, and health concerns.
The increase in patients following a vegan diet can lead to requests for provider advice about the safety of this dietary pattern. Several studies have demonstrated health benefits of plant-based diets, including improvements in ischemic heart disease mortality, as well as decreases in hypertension, hyperlipidemia, obesity, type 2 diabetes mellitus, and cancer incidence.
Despite these benefits, could vegans be at risk for deficiency of essential nutrients? The present article concisely summarizes the recent literature examining potential negative consequences of a vegan diet and assists clinicians in their conversations with patients.
