Eating meat and dairy products is the SAD (Standard American Diet) diet. The SAD diet can only make you sad. It causes heart disease, cancer, diabetes and makes you fat. Raising animals for food destroys the environment... And those animals are not happy. They are enslaved and live humiliating, fearful lives of abuse and tremendous suffering. Veganism turns sadness into joy.
In fact, we would know ourselves that we are not meant to be meat eaters, and we would not have allowed ourselves to become conditioned to meat eating in the first place, if the effects of meat eating were felt right away. But since heart disease, cancer, diabetes, osteoporosis, etc. usually take many years to develop, we are able to separate them from their cause (or contributing factors) and go on happily eating an animal-based diet.
It's a common myth that athletes and other highly active people need the protein from meat and dairy to fuel their activities and build and repair muscles and other bodily tissues. In fact, there is growing evidence that consumption of too much protein can lead to very serious health issues, including kidney disease, osteoporosis, and cancer. The active body can get all the protein it needs from a diverse, 100% plant-based diet.
