Although meat is certainly a source of concentrated protein it is a very poor source of other food elements like minerals, vitamins and carbohydrates. In addition, eating flesh from the cow or any other animal is detrimental to the health of human beings for many reasons. For example, if a human, who has a much longer colon than the carnivorous animals, eats flesh, the following problems will ensue:
The minimum daily requirement of protein, which nutritional experts calculate to be between seventy and ninety grams, is easily achieved with dairy products and foods from the vegetable kingdom. Protein is found in ample quantity in milk, cheese, yogurt, whole wheat, corn, many varieties of nuts and beans, and some vegetables. Thus vegetables, fruits, grains and dairy products provide a perfectly balanced diet. Consuming animal flesh, on the other hand, results in excess protein, which produces liver ailments, high blood pressure, and hardening of the arteries.
In addition, dead animal flesh contains many toxic elements, such as:
Due to forced feeding, penning, and other unnatural practices, animals raised for slaughter suffer from dozens of diseases, such as foot-and-mouth disease, fevers, catarrhal conditions, cancer, tuberculosis, and mastitis. In addition, poultry are often impregnated with estrogens, which can cause cancer. Many studies in cancer research reveal that areas in which meat-eating is highest tend to have the highest cancer rate, while vegetarian areas generally have a far lower rate.
Immediately after an animal is slaughtered, rigor mortis sets in, and then the process of decay takes over. Thus meat-eating always involves consumption of decayed flesh together with its incumbent dangers to health.
Meat-eaters may wonder, “But meat is a perfect, complete protein, while I’d have to spend hours purchasing, cooking, and combining the right vegetables to get enough protein every day.”
First of all, meat is not “pure” or “perfect” protein, but at best 25-30% protein. Its net protein utilization (NPU, the amount actually digested and absorbed by the body) is 67%, compared to 82% for milk, 70% for cheese, 67% for mung beans, and 60% for whole wheat. By weight the above foodstuffs may have less protein than meat, but because their NPU is high, simply by eating more of them or combining them one can easily meet one’s protein RDA (minimum recommended daily allowance). For example, milk is only 4 to 5% protein, but two cups give about 40% of the average usable protein RDA of 43.1 grams. A two-inch cube of cheese yields about 30%. And the objection that vegetarianism is too time-consuming is ridiculous. Complementarity, the right combination of foods, is as common-sense and natural as bread and butter, and it easily avoids dietary deficiencies. Furthermore, complementarity increases the food value of the combined foods. For example, the NPU of rice alone (60%) and beans alone (40%) increases by 43% when they are eaten together, and pairing milk with whole-wheat bread increases their combined NPU by 13%.
Besides, protein isn’t everything. Essential nutrients like iron, potassium, magnesium, and calcium, as well as essential vitamins like C, A, riboflavin, niacin, and the B complex, are almost entirely absent in flesh foods. Vegetarian foods are absolutely necessary to maintain good health.
