The fact that human body is designed to take in only vegetarian food has always been an important topic of discussion. With a close look on our features and comparing it with animals' the solution lays bare before us. The structure of our teeth closely matches that of a herbivore than a carnivore. The flat stretch of front teeth and the grinding teeth that follow are the basic structure and dental design in a herbivore.Carnivores has only rows of canines that are used to tear meat into pieces. Flat teeth are uncommon in such animals.Considering the cases of omnivore (consumes both vegetarian and non-vegetarian) along with the flat teeth and the grinding teeth supplementary pairs of canines will be included which can be a paragon for human dental structure. But this seems to be modification that have taken place after years of evolving. When analyzing the teeth structures of primitives as their primary food was plants and their parts the skeletal remains leaves us evidences of pure vegetarians.
But we can never neglect the fact that in European countries to survive the extreme cold conditions intake of fat and meat is inevitable to maintain their body temperature. That is the reason why they consume far more multiples of the amount of meat we eat.For them a condition without including meat in their diet will often chance their survival during extreme climatic conditions. As for us exclusion of meat from our diets will cost us nothing more than reduction in the number of side dishes for our meals.
The inclusion of such non-vegetarian varieties came to India with the arrival of the Mughals, The Britishers and many such usurpers who brought in heavily their life style upon us. By the introduction of Christianity the western mode of living affixed itself into the lives of Indians.Although Indian cuisine included marine varieties especially from the coastal menus such large quantities and qualities of non-vegetarian dishes entered into our's when we began to copy what the English did. Not just the food habits but attire, style, speech, mode of living, and many more.
When it comes to the question of which is better, the answer that suites in best would be vegetarian. A carnivore kills as to feed itself and never kills for sport. As part of the food chain the entire design of a carnivore supports only the intake of meat. But as for us, our system supports vegetarian diet the most.In Kerala we resort to non-vegetarian diet only for the pleasure of our senses . When religion takes in the role of proclaiming the use of non-vegetarian diet we have to remember that these religions when considering the source of their birth (place of birth), inclusion of non-vegetarian diet is inevitable for the climatic conditions there. When compared to the moderate climate of Kerala the maximum our body can afford, to go in hand with our climatic conditions and necessities, is a vegetarian diet and if necessary marine or freshwater fish items and eggs.
