More and more people are opting for a vegetarian diet, driven by concerns for health, animal welfare and the environment. This dietary model comes in many variants as veganism, lactovegetarianism or flexitarianism, among others, and, if well balanced, can bring numerous benefits: improvement of the digestive system, reduction of the risk of lifestyle diseases, better wellbeing and cancer prevention. In the diet rankings organised by U.S. News & World Report, flexitarianism and veganism were rated particularly highly - for their health-promoting effects and ease of use.
