Diets

Diet is the collection of food and drink that someone consumes. A healthy diet, which means eating various groups of food in right quantities, leads to a healthy lifestyle. Experts say grains, fruits, vegetables, protein, and diary are necessary types of food for a balanced diet. As holozoic heterotrophs, human beings have a wide range of choices to supplement their diets which allows them to change their diet when desired. Thousands of different types of diets are used around the world for various reasons, like losing or gaining weight, having long healthy life, acquiring culinary habits, religious believes, clinical problems, and so forth. Unlike humans, most animals and plants have their constant diets. Based on their containing materials,

Most animal species are either carnivorous or herbivorous, while some of them such as bears, crows, and rodents are omnivores. Some nutritionists call omnivores as opportunistic feeders, since there is no limitations in omnivorous diets and they are free to consume any type of food which is available. Omnivorous diet has the widest possibility of variation, hence it does not have a typical diet plan. Omnivores are divided into two groups: the first group are mainly meat eaters, because they consume meat very often; the next group follow a flexitarian diet, a diet that includes meat very hardly.

Ovo-vegetarians concern about slaughtering male calves, denying calves’ source of milk, and continuously keeping cows pregnant to lactate.
