Veganism is a philosophy and way of living that avoids all animal products like meat, dairy and eggs. Going vegan for a month can have significant health benefits as it leads to a plant-based diet higher in nutrients. Campaigns like Veganuary encourage people to try veganism in January to raise awareness of the lifestyle. Vegans must ensure they get essential nutrients from plant sources and fortified foods, though vitamin B12 supplementation is important. Adopting a vegan diet can help prevent diseases and reduce symptoms like PMS. Veganism also benefits the environment by avoiding intensive animal agriculture which uses significant resources and emits greenhouse gases.
