Veganism is a philosophy that seeks to avoid animal exploitation and promotes a plant-based lifestyle. It is a controversial way of living that differs from social norms. The Veganuary campaign encourages people to try veganism in January. While vegan diets require care to ensure adequate nutrient intake, they may provide health benefits by reducing disease risk and improving personal health. However, claims about benefits related to women's menstrual cycles require more research. Veganism also helps the environment by reducing agricultural land and water use compared to meat production.
