Eating raw meat is considered an alternative to over-cooking. This often destroys part of the necessary enzymes and proteins but raw meat can cause food poisoning, indigestion and often increases the risk of salmonella or tapeworm infection. Unfortunately, these aren’t the only bad effects of consuming raw meats.
Meat is an essential part in any optimal dietary scheme, in the proper physical and mental development of children, in illness treatment or recovery diets, and, overall it is critical for being healthy and fit. Although, people can and some even do live without consuming animal flesh and by-products (like eggs, milk), the vitamins and proteins from these sources can not be completely replaced by any other natural food, whether vegetables, grains or fruits. Vegans, for instance, have to take artificial supplements to make up for the lack of animal nutrients, which can not really be a wholly healthy practice.
