A vegan diet excludes all animal products. Many people choose to eat this way for ethical, environmental, or health reasons.
There are several ways to follow a vegan diet, but scientific research rarely differentiates between the different types.
Vegan diets seem very effective at helping people naturally reduce the number of calories they eat, resulting in weight loss.
Vegan diets seem particularly effective at improving markers of blood sugar control. They may also lower the risk of developing type 2 diabetes.
Vegan diets may improve heart health. However, more high quality studies are needed before researchers can draw strong conclusions.
A vegan diet is linked to several other health benefits. However, more research is needed to determine whether the diet was a direct cause of those benefits.
Vegans avoid consuming any animal flesh, animal byproducts, or foods containing an ingredient from animal origin.
