Human body is very different from body of carnivorous animals. Human body cannot identify and differentiate the fat irrespective of whether it is obtained from vegetarian source or non-vegetarian source. Digestive system only does its work and tries to digest fat irrespective of its source. Digestive system of carnivores animal is very strong when compared to human beings. Since they have to solely depend upon living beings to obtain energy, their digestive power is quite enhanced. Their digestive system is so strong that it can extract more and more amount of carbohydrates and fat and digest everything completely. No ill-effects of any sort are imparted on their body. This is not the case with human beings. Their digestive power is not that strong. Digestive system of human beings is made for digesting vegetarian food which is light and easily digestible.
When human body consumes non-vegetarian food, its digestive system is able to digest only a part of it. Only that much of carbohydrates and fat is utilized as is needed for the body, rest is left unused. If consumption of non-vegetarian food is continued for a long period of time or if made as a life style then the fat rich element starts accumulating within the inner wall of arteries of heart. Continued accumulation of fat within inner walls of arteries will thicken them from inside and they will become constricted as a result blood flow to the heart slows down. This condition is known as arteriosclerosis. Heart should get sufficient amount of blood it requires all the time. This blood carries required amount of oxygen in it. Arteriosclerosis is a condition where this supply is cut down and this slows down effective working of heart thereby reducing heart beat. As a consequence to this stage comes heart attack. Apart from arteriosclerosis, clot formation in blood is also seen in people who consumes excess of non-vegetarian food and if the clot formation is in the blood vessels of vital organs like heart, brain, kidney etc..... then blood supply to these vital organs is greatly diminished resulting in a fatal failure of these vital organs.
Fat of animal products is not only responsible for causing heart attack, arteriosclerosis and damage to vital organs but is also responsible for causing deadly cancer. Colon is a part of large intestine. It is present at lower end of large intestine. Since human intestines are not designed for digestion of animal products, colon most of the times may get diseased and become cancer prone. Before undigested food enters excretory system, it remains in colon for a certain period. Rich fibrous foods gets digested easily and hence does not affect colon or other parts of intestine. Non-vegetarian food is devoid of fiber and thus undigested toxic non-vegetarian food passes very slowly through colon and remains in it for a long time and this is a very important reason that it gets affected with cancer. Not only colon, rectum is also affected equally. Thus, fiber rich diet is essential to prevent colon and rectal cancer. During digestion of animal fat, steroid metabolism is formed. It is responsible for causing carcinogenic cancer.
Non-vegetarians not only have to worry about the weak digestive power they have within them but also regarding other products that are very toxic and in spite of their toxicity given to birds and animals right form their birth and sometimes even before birth. These toxic materials help animals and birds to accumulate fat within their bodies. Excess of fat increases their price. But the real price is to be paid by human body who consumes them. These toxic materials not only remain limited to animals and birds but also reaches human body through the fat that they are consuming. Some of such toxic products are tranquilizers, hormones, antibiotics and many such medications. Animals are injected with higher doses of antibiotics. This keeps them alive because sustainability is difficult in their case as a question can be raised on the hygiene in which they are kept. The shelter they are provided is very unhygienic and rarely care is taken to keep it clean. Thus, they are affected with lots of diseases. Antibiotics help them to fight with diseases. However, these antibiotics not only remain limited in their body but also enter human body who consume animal fat. Not only antibiotics, in fact antibiotics resistant bacteria too enters human body which was initially produced in animal body due to excess of antibiotics ingested in them. If human beings consume animal fat in excess, may die of toxins present in it. In fact kids if are given animal fat even in small amount also can experience hazardous effects on their health and body.
Sodium nitrate and sodium nitrite are another two harmful chemicals sprayed in excess on various animals fat and also on fishes. These chemicals will keep animal fat from being spoiled and provide rich red color to it when it reacts with blood pigmentation. Animals are also scared of death and thereby excess of uric acid is present in their blood. This excess of uric acid also enters human body. It's a waste product our body produce which gets excreted out and excess ingested in human body through animal fat exerts poisonous effects on body.
Human body requires certain amount of carbohydrates and fat daily. Though one can obtain sufficient amount of carbohydrates and fat from animal fat, it also brings with it lots of toxins and hazardous effects. Thus nutrition and daily requirement of body should be obtained by following a healthy balanced vegetarian diet which is in rich in fibrous fruits and vegetables. Such diet will keep us healthy and enhance longevity by keeping diseases and disorders of all types away. Let us not depend on animal fat as human body is not designed to digest it. Instead of challenging our body and ingesting in it unwanted toxic materials, let us keep it free from toxins. Apart from caring about our health, let us also care about animals and help them to survive and breathe freely instead of preying on them.
