Vegan is a style of eating in which no animal products at all are consumed. This includes meat, fish, or poultry, and foods that are derived from these animals like milk, eggs, lard, or even honey. When following a vegan diet, you can eat anything made from plants, which is why it’s also sometimes called the “plant-based” diet. Vegans can eat beans, legumes, grains, nuts, seeds, and of course fruits and vegetables.
