In today's modern, practical and fast-paced society people are becoming more health conscious. This includes trying to choose the best options available for a beneficial lifestyle. Exotic Greek salads, fresh juices, delicate tofu preparations, stinky grilled vegetables, creamy grain soups, moist soufflés and much more are common choices for many people's meals. Nowadays they are becoming increasingly concerned about the growing health risks of a meat-based diet. On the other hand, others have gone a step further and believe that animal cruelty involving killing animals and using them for their products is inhumane and should be outlawed. Since meat consumption has been an accepted part of the human diet across the spectrum of many civilizations for millions of years, a controversy emerges between those who want the use of animal products to be banned and those who enjoy a steak that much meanwhile. Should people consider going vegan? In general, veganism refers to the consumption exclusively of vegetables and the total abstention from products of animal origin. Anthropologists believe, according to their studies of many human fossils around the world, that sixty-five million years ago most humans ate primarily plant foods, being more likely gatherers than hunters. Indeed, the human digestive system resembles this primitive vegetarian condition of other herbivores in coprolites and rudimentary tools discovered through archaeological finds at early human settlements. As the climate changed, the physical structure also changed: the discovery of fire and increased brain size changed the diet to include meat products. These facts, advocates of banning animal products argue, demonstrate that humans are not meant to eat meat. Promoters of the vegan lifestyle point out that chronic diseases have decreased, proteins can be obtained through plant sources, and animals should not be slaughtered if possible. They also list the following benefits of being vegan.
