Vegans refer to a community who follows a vegetarian diet which excludes meat, egg, dairy products, garlic, onions, wine and animal-derived food products.
Some people easily switch from normal diet to become a vegan while others struggle with the commitment. However, it all comes down to your goal. What is your objective to become a vegan? For health reasons, religious, human rights or animal rights?
The question to ponder upon - are homo sapiens herbivores, omnivores or carnivores originally?
I would say that we are anatomically more similar to herbivores. Humans do have very long intestinal tract like the herbivores. Carnivores have shorter gastrointestinal tracts (GIT) and their stomachs are 20 times more acidic than that of humans and herbivores.
We do not have acidic saliva like carnivores but we have alkaline saliva to digest plants. Besides our GIT have villi to help slow absorption of nutrients. The bowels of carnivores are smooth. Herbivores and humans need fibers in their diet to help the peristalsis of food through the long digestive tracts. Carnivores have sharp teeth and claws to hunt for preys, humans and herbivores don't.
Omnivores are anatomically more similar to carnivores. Therefore, we are not omnivores either. For detailed comparison, please visit the site below:

A religious friend once told me that when an animal is killed for meat, it stresses up the animal and its body will release toxins which is bad for humans. The same goes with chickens and cows which are bred and forced into eggs and milk production.
We all have a choice. It's up to the individual. What works for you may not work for others.
