People who are vegans consume only plant-based foods, and avoid eating anything from an animal, including dairy, honey, eggs, and gelatin. You may wonder why a growing number of individuals are choosing this benevolent and healthful diet. Some people become vegan after they learn about factory farms, like dairy operations where cows are harshly exploited to get the maximum output of milk. Finding this unbearably cruel, they look for alternatives. Others choose a plant-based diet for health reasons. Multiple studies have demonstrated consuming meat increases the risk of major health problems over time.
