Becoming a vegan requires you to make drastic changes to your diet. You have to eliminate anything of animal origin, which includes meat, seafood, cheese, milk, eggs, fish and gelatin. Vegan diets are naturally low in saturated and trans fats, reducing your risk of developing heart disease and related complications.
Vegan diets can obtain all the essential nutrients by eating plant-based foods. Veganism is a strict type of vegetarianism that excludes meat and all animal products. Vegans do not eat meat, fish, eggs, dairy products, or any foods containing them. A vegan diet relies on plant-based foods including fruits, vegetables, grains, beans, nuts, and seeds.
