According to official medical sources, vegan are strict vegetarians that never eat animal and dairy products, no matter if we are talking about eggs or yoghurt. Moreover, being a vegan means not using animal tested products, or clothes that are made of leather or wool and others such. Some of the main benefits of being a vegan mainly refer to the health advantages that are to be drawn from such a lifestyle. For instance, animal fats and animal proteins can boost the risk of developing serious diseases such as cancer, diabetes, cardiovascular diseases, hypertension, and even arthritis, to name just a few of the more serious ones. According to vegans, the milk that comes from cows or goats, for instance, has a completely different content as compared to human milk. They claim the human body is not designed to ingest milk coming from cows and other milk-producing animals.
